  • Biomimetic Soft Underwater Robot Inspired by the Red Muscle and Tendon Structure of Fish
    Daisuke Aragaki; Toi Nishimura; Ryuki Sato; Aiguo Ming
    Biomimetics, MDPI AG, 8, 2, 133-133, 24 Mar. 2023, Peer-reviwed, Underwater robots are becoming increasingly important in various fields. Fish robots are attracting attention as an alternative to the screw-type robots currently in use. We developed a compact robot with a high swimming performance by mimicking the anatomical structure of fish. In this paper, we focus on the red muscles, tendons, and vertebrae used for steady swimming of fish. A robot was fabricated by replacing the red muscle structure with shape memory alloy wires and rigid body links. In our previous work, undulation motions with various phase differences and backward quadratically increasing inter-vertebral bending angles were confirmed in the air, while the swimming performance in insulating fluid was poor. To improve the swimming performance, an improved robot was designed that mimics the muscle contractions of mackerel using a pulley mechanism, with the robot named UEC Mackerel. In swimming experiments using the improved robot, a maximum swimming speed of 25.8 mm/s (0.11 BL/s) was recorded, which is comparable to that of other soft-swimming robots. In addition, the cost of transport (COT), representing the energy consumption required for robot movement, was calculated, and a minimum COT of 0.08 was recorded, which is comparable to that of an actual fish.

  • Design and Implementation of Symmetric Legged Robot for Highly Dynamic Jumping and Impact Mitigation
    Lei Wang; Fei Meng; Ru Kang; Ryuki Sato; Xuechao Chen; Zhangguo Yu; Aiguo Ming; Qiang Huang
    Sensors, MDPI AG, 21, 20, 6885-6885, 17 Oct. 2021, Peer-reviwed, Aiming at highly dynamic locomotion and impact mitigation, this paper proposes the design and implementation of a symmetric legged robot. Based on the analysis of the three-leg topology in terms of force sensitivity, force production, and impact mitigation, the symmetric leg was designed and equipped with a high torque density actuator, which was assembled by a custom motor and two-stage planetary. Under the kinematic and dynamic constraints of the robot system, a nonlinear optimization for high jumping and impact mitigation is proposed with consideration of the peak impact force at landing. Finally, experiments revealed that the robot achieved a jump height of 1.8 m with a robust landing, and the height was equal to approximately three times the leg length.

  • Bio-Inspired Take-Off Maneuver and Control in Vertical Jumping for Quadruped Robot with Manipulator
    Ru Kang; Fei Meng; Lei Wang; Xuechao Chen; Zhangguo Yu; Xuxiao Fan; Ryuki Sato; Aiguo Ming; Qiang Huang
    Micromachines, MDPI AG, 12, 10, 1189-1189, 30 Sep. 2021, Peer-reviwed, The jumping motion of legged robots is an effective way to overcome obstacles in the rugged microgravity planetary exploration environment. At the same time, a quadruped robot with a manipulator can achieve operational tasks during movement, which is more practical. However, the additional manipulator will restrict the jumping ability of the quadruped robot due to the increase in the weight of the system, and more active degrees of freedom will increase the control complexity. To improve the jumping height of a quadruped robot with a manipulator, a bio-inspired take-off maneuver based on the coordination of upper and lower limbs is proposed in this paper. The kinetic energy and potential energy of the system are increased by driving the manipulator-end (ME) to swing upward, and the torso driven by the legs will delay reaching the required peak speed due to the additional load caused by the accelerated ME. When the acceleration of ME is less than zero, it will pull the body upward, which reduces the peak power of the leg joints. Therefore, the jumping ability of the system is improved. To realize continuous and stable jumping, a control framework based on whole-body control was established, in which the quadruped robot with a manipulator was a simplified floating seven-link model, and the hierarchical optimization was used to solve the target joint torques. This method greatly simplifies the dynamic model and is convenient for calculation. Finally, the jumping simulations in different gravity environments and a 15° slope were performed. The jump heights have all been improved after adding the arm swing, which verified the superiority of the bio-inspired take-off maneuver proposed in this paper. Furthermore, the stability of the jumping control method was testified by the continuous and stable jumping.

    Zewen He; Fei Meng; Huaxin Liu; Lei Wang; Xin Zhu; Xuxiao Fan; Ryuki Sato; Aiguo Ming; Qiang Huang
    CISM International Centre for Mechanical Sciences, Courses and Lectures, Springer International Publishing, 584, 323-330, 2019, In the field of robotics, small cat-like robots, due to its small size, good flexibility, low energy consumption, has become a research trend. Elastic four-bar linkage mechanism (EFLM) with programmable trajectory, good stability, and certain buffer performance, is an excellent choice for driver design of small quadruped robot. We designed a novel miniature cat-like robot, Og-cat, which is optimized in structural features and special parameters compared with other similar quadruped robots. Moreover, we developed a method that can make leg trajectory implement accurately for robots using EFLM. A trajectory realization function is obtained through MATLAB fitting so that the trajectory can be executed precisely. The proposed method has been confirmed on our small quadruped robot Og-cat.

  • Development of a proximity sensor for robot hand to grasp at arbitrary fingertip position
    NAKAYAMA Takumi; FURUTA Takato; ARITA Hikaru; MING Aiguo
    The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), The Japan Society of Mechanical Engineers, 2019, 2A2-G07, 2019, We are developing robot hands with proximity sensors capable of acquiring information on the vicinity of an object. Up to now, a grasp posture at which the fingertip is facing directly to the object is considered and network structure proximity sensors have been designed for the grasping. By using the proximity sensors, it is difficult to realize a grasping at an arbitrary position of the fingertip, which is necessary for complicated grasping tasks. In this paper, a network structure proximity sensor is designed to meet the need and basic characteristics are investigated by experiments using a prototype of the sensor.

    PROCEEDINGS 2018 12TH FRANCE-JAPAN AND 10TH EUROPE-ASIA CONGRESS ON MECHATRONICS, IEEE, 230-235, 2018, Peer-reviwed, In the animal kingdom, many mammals are using their tails to assure their stability while running, jumping, falling, etc. Researches have been performed in order to add tails on wheeled or legged robots in order to improve their stability. However, those tails are often far from the biological structure and resumed to a simple rigid tube with a mass on the extremity. On the other hand the biological tail is composed of many bones moving one on the other and actuated with an important number of muscles. Therefore replicating this structure would result in big and heavy systems using many actuators that would reduce the physical performances of the robot. In this paper, we developed a new bio-inspired cable-driven tail system capable of swinging a flexible tail from base to tip around the pitching axis using a single actuator. First we designed a new flexible tail mimicking the structure of the animal tail. Then we developed a new actuation system using the combination of cams and drive wheels to realize the actuation of 8 cables using a single actuator. Finally, we measured the efforts generated by the swinging motion of the tail and perform experiments to observe its effects on the jumping motion.

  • Robotic Grasping Using Proximity Sensors for Detecting both Target Object and Support Surface
    Sasaki, Koichi; Koyama, Keisuke; Ming, Aiguo; Shimojo, Makoto; Plateaux, Regis; Choley, Jean-Yves
    2018 IEEE/RSJ INTERNATIONAL CONFERENCE ON INTELLIGENT ROBOTS AND SYSTEMS (IROS), IEEE, 2925-2932, 2018, Peer-reviwed, The robustness of the positioning and posturing of robot hands relative to target object and support surface is an important issue for autonomous grasping. For example, to perform a grasping action such as picking up thin objects from a table top, the position and posture of the hand must be controlled to keep adequate relative posture and distance to the support surface besides those between the hand and the target object. Because slight errors in the posture and position are enough to cause grasping failure, the positioning and posturing of the hand must be precise enough, specially when the hand is close to the target object and support surface. To improve the robustness of robotic grasping, in this paper we present a method by grasping control based on the relative posture and position between hand and support surface besides those between hand and target object, using proximity sensors. Proximity sensors are newly installed on fingernails besides on the fingertips. As the fingernail sensor, an integration of Time-of-Flight (TOF) sensor and photo-reflector is designed to realize long range detection, as well as with precise and high-speed detection regardless of the reflectance of support surfaces when approaching the support surface. By the sensors, the hand can approach the object and support surface coarsely first, and then can be controlled fast and precisely to realize adequate grasping motion along the support surface but without contact with the support face. The method has been implemented to a manipulator system, and successful grasping experiments have demonstrated the effectiveness of the proposed method.

    2018 IEEE INTERNATIONAL CONFERENCE ON CYBORG AND BIONIC SYSTEMS (CBS), IEEE, 391-396, 2018, Peer-reviwed, In this paper, a new leg mechanism that mimics the function of the musculoskeletal structures of the thigh of the mammals is proposed. The bi-articular muscle-tendon complex of the thigh makes it possible to drive the hip and the knee joints as well as store and release the elastic energy, and it contributes to extension of the leg at the jumping and swinging of the leg during running. A mechanism with the function is introduced to a bipedal robot that mimics the hind limbs of mammals. In order to verify the effect of the mechanism, motion planning for the vertical jumping is performed for the models with and without the mechanism by a nonlinear optimization simulation. The motion trajectory is optimized to maximize the jumping height and the derived results show that the jumping height can be improved by the mechanism. Through the experiments, it is confirmed that the jumping height by the bipedal robot with the proposed mechanism was improved and the effectiveness of the proposed mechanism is shown.

  • Development of High-Performance Soft Robotic Fish by Numerical Coupling Analysis
    Zhao, Wenjing; Ming, Aiguo; Shimojo, Makoto
    APPLIED BIONICS AND BIOMECHANICS, HINDAWI LTD, 2018, 1-12, 2018, Peer-reviwed, To design a soft robotic fish with high performance by a biomimetic method, we are developing a soft robotic fish using piezoelectric fiber composite (PFC) as a flexible actuator. Compared with the conventional rigid robotic fish, the design and control of a soft robotic fish are difficult due to large deformation of flexible structure and complicated coupling dynamics with fluid. That is why the design and control method of soft robotic fish have not been established and they motivate us to make a further study by considering the interaction between flexible structure and surrounding fluid. In this paper, acoustic fluid-structural coupling analysis is applied to consider the fluid effect and predict the dynamic responses of soft robotic fish in the fluid. Basic governing equations of soft robotic fish in the fluid are firstly described. The numerical coupling analysis is then carried out based on different structural parameters of soft robotic fish. Through the numerical analysis, a new soft robotic fish is finally designed, and experimental evaluation is performed. It is confirmed that the larger swimming velocity and better fishlike swimming performance are obtained from the new soft robotic fish. The new soft robotic fish is developed successfully for high performance.

    2018 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND BIOMIMETICS (ROBIO), IEEE, 287-292, 2018, Peer-reviwed, This paper presents a robot with pseudo direct drive and multi-springs inspired from structure of a cat. Combining spring and cable pulley, the passive flexible mechanical structure is realized by two parts: an elastic four-bar linkage crossing the knee and ankle joints; a sprung cable crossing the hip, knee and ankle joint. The structure can make full use of robot's gravitational energy and motor power to store more energy in landing, and then release energy in jumping, which enhances dynamic jump ability. Besides, the robot can maintain a standing state stably under static condition balance with the help of spring which avoids overheating of the motor and improve energy efficiency. Simulation and experiments demonstrated that the multi-springs can reduce the load of knee joint motor and the jumping height of the robot with the springs was 42 mm higher, which show an obvious effectiveness in jumping function.

    2018 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND BIOMIMETICS (ROBIO), IEEE, 1226-1231, 2018, Peer-reviwed, The extraordinary jumping ability of quadrupedal animals, is greatly attributed to appropriate jumping motion strategy with elastic element in legs. This paper introduces an optimization process of the robot jumping to a maximum horizontal distance from a static state, and verifies it on a small quadrupedal robot using elastic four-bar linkage mechanism. Two steps of optimization, with simplified stick models built to depict the dynamic characteristics of real robot, was set to search a best jump motion. Moreover, experiments of real robot validate the effectiveness of the mechanism and optimizing jumping method, while the robot could achieve a maximum horizontal jumping distance of 250 mm (78% of body length).

  • Bioinspired Control of Walking With Toe-Off, Heel-Strike, and Disturbance Rejection for a Biped Robot
    Xuechao Chen; Zhangguo Yu; Weimin Zhang; Yu Zheng; Qiang Huang; Aiguo Ming
    IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 64, 10, 7962-7971, Oct. 2017, Peer-reviwed, Human-like features, like toe-off, heel-strike, and disturbance rejection, can enhance the performance of bipedal robots. However, the required control strategies for these motions influence each other, and few studies have considered them simultaneously. Humans can walk stably with toe-off and heel-strike even after experiencing disturbances. Thus, we can study human control strategies, and then, apply them to a bipedal robot. This paper proposes a bioinspired control method to realize stable walking with toe-off and heel-strike for a bipedal robot even after disturbances. First, we analyze human walking and obtain some control strategies. Then, we propose a pattern generator and a walking controller to mimic these strategies. The pattern generator can predefine the zero-moment-point to plan the center of mass trajectory and determine appropriate foot placement. The controller adjusts torso acceleration to make the support leg compliant with the external disturbances. The controller also achieves toe-off and heel-strike in cooperation with the pattern generator. Finally, the validity of the proposed method is confirmed through simulations and experiments.

  • Robotic Grasping Using Proximity Sensors for Detecting both Target Object and Surrounding Environment
    SASAKI Koichi; KOYAMA Keisuke; MING Aiguo; SHIMOJO Makoto
    The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), The Japan Society of Mechanical Engineers, 2017, 2P1-B11, 2017,

    Grasping thin objects on the table is difficult because a slight angular error of the robot hand causes grasping failure. Besides, unintended contact with surface of the table causes not only grasping failure but also malfunction of the robot hand. Therefore, In the grasping, posture adaptation between hand and environment is important for successful grasping. In this paper we present a grasping method for thin object using finger pad and nail proximity sensor which can detect both object and surrounding environment. Because the nail proximity sensor is consisted of photo reflector and TOF proximity sensor, angular and distance error between the hand and the surrounding environment can be detected and corrected during approach to the object. As an experimental result, we show that the proposed method has robustness for environment and can grasp thin object on the table even if angular error exists.

    The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), The Japan Society of Mechanical Engineers, 2017, 2P1-B10, 2017,

    We verified the effectiveness of presentation method of the object plane information by electrotactile stimulation based on proximity sensor outputs. The proximity sensor is able to obtain distance and posture information between the sensor and the object at the area near the object, and mounted on a robot fingertip. If the proximity information is transmitted to the operator, it is useful for the operator to grasp the object in teleoperation robot. Especially, we focused on posture presentation in this paper, by which operator can make the robot fingertip confront the object. The experiment all results show the possibility that the proposed method enables the operator to adjust the grasping posture.

    The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), The Japan Society of Mechanical Engineers, 2017, 2P1-B09, 2017,

    In industrial field and home service field, there is required to grasp various objects with one type of a hand. Since fingertips of multi-D.O.F hand have a wide movable range, it is suitable for grasping objects with various shape and size. In our laboratory, we have developed the hand equipped with proximity sensors. And we realized a pre-grasp motion which adjusts distance and posture between the fingertip and an object without touching it. However, the hand used is expensive custom-made items, and there is problems that a controller is large and expensive. In this research, we develop a low-cost robot hand equipped with the proximity sensor. This robot hand consists of RC servo motors, which has advantages of easy maintenance, easy installation and low-cost.

    Yu, Dacheng; Yu, Zhangguo; Chen, Xuechao; Huang, Qiang; Shi, Yongliang; Zhu, Min; Zhang, Weimin; Ming, Aiguo; Shimojo, Makoto
    2017 CHINESE AUTOMATION CONGRESS (CAC), IEEE, 445-450, 2017, Peer-reviwed, Compliance control using tactile sensor for robotic hands have been one of the major research topics. Most researchers use a variety of multi-dimensional force sensors with compliance control. In this paper, we replace traditional multi-dimensional force/torque sensor with one-dimensional pressure sensor. In order to achieve the effect of multi-dimensional sensor, we also propose a vector decomposer to calculate the three-axes position error vector from one-dimensional position signal and make it works in position based impedance control. Finally, the performance of the vector decompose algorithm and compliance grasping are verified in simulation and experiment.

  • Reuse of SysML Model to Support Innovation in Mechatronic Systems Design
    Mizuki Shinozaki; Faida Mhenni; Jean-Yves Choley; Aiguo Ming
    2017 11TH ANNUAL IEEE INTERNATIONAL SYSTEMS CONFERENCE (SYSCON), IEEE, 50-55, 2017, Peer-reviwed, Mechatronic systems are inherently complex as they are multidisciplinary, integrating both hardware (electronical, mechanical) and software components. A huge effort is needed in the early design stages to take into account the requirements and constraints of the different stakeholders. A system model is needed to facilitate the communication between the collaborators from different domains. These efforts may be considered as a time loss by several companies. However, when a system model is available (i.e. electrical actuator for aircraft industry), it seems obvious that designing a new variant of the system with a modification of a set of requirements requires much less human effort, as it profits from the reuse and change of the already existing models of the previous system. In this paper, we propose to show the usefulness of the capitalization and reuse of system models by showing how a SysML model of an E-Taxiing (Electric Taxiing) aircraft system can be reused in order to design a new innovative HEPS (Hybrid Electric Propulsion System).

  • 2足歩行安定性を向上する足裏実装型非接触センサの開発
    有田 輝; 米田 将允; 鈴木 陽介; 下条 誠; 明 愛国
    日本ロボット学会誌, The Robotics Society of Japan, 35, 9, 669-680, 2017, Peer-reviwed, For bipedal robots walking on uneven terrain, lack of information about a terrain may cause serious reduction of the stability. To solve the problem, the purpose of this paper is to develop a sensor which can be mounted on robot's soles and propose methods which can increase the stability of bipedal walk with the sensor. The sensor should detect information including relative posture and relative distance between the sole of the swing leg and the floor, when the robot execute the walk by ZMP-based control. In this paper, the sensor has been designed based on Net-Structure Proximity Sensor (NSPS) and a prototype has been developed. The developed sensor is with thin structure, light weight, less wirings (four wires only) and fast response (<1[ms]). Experimental results show that the sensor can output necessary relative posture and positon between the sole and the floor for walk control. Besides, the sensor has been mounted to the soles of a hobby robot and its feasibility is shown by controlling robot so that its sole can land on a tilted floor with maximum contacting area to improve the stability.

  • Design of biomimetic soft underwater robots
    Aiguo Ming; Wenjing Zhao
    Mechatronic Futures: Challenges and Solutions for Mechatronic Systems and Their Designers, Springer International Publishing, 91-111, 01 Jan. 2016, Peer-reviwed, The evolution process for creatures is very, very long, and contains many useful secrets and rationality mostly hidden in their structure, motion and configuration. Biomimetic mechatronic design is a useful approach for future mechatronic innovation, which can significantly enhance the performance of mechatronic systems. As an important issue for biomimetic mechatronic design, it is necessary to make a robot as soft as a natural creature to achieve more efficient, high-performance and creature-like motions. Compared to a conventional rigid robot, the design and control of a soft robot is difficult because the coupling between the flexible structure and surrounding environment should be considered, which is very difficult to resolve due to the large deformations and complicated and coupled dynamics. This is the main reason why design methods for soft robots has not been established, despite the many trial developments of soft robots that have been undertaken to date. The challenges for the design of biomimetic soft underwater robots based on numerical simulation considering the coupling between the flexible structure and surrounding fluid as well as control technologies are described in this chapter.

  • 指先に光学式近接覚センサを備えた多指ハンドによる同時接触での把持 (物体表面の反射率推定とセンサ出力の補正)
    小山佳祐; 鈴木陽介; 明愛国; 下条誠
    日本機械学会論文集, The Japan Society of Mechanical Engineers, 82, 833, transjsme.15-00366-00366-15-00366, Jan. 2016, Peer-reviwed, In grasping of a robot hand, a contact timing of each finger has a influence on grasp success. In order to eliminate the gap and grasp an object quickly, proximity sensing from the robot surface is effective way. The sensor detects the object posture and distance in a several tens of millimeters from the robot surface. It enables that the robot adjusts postures and distance between the object and fingertips along the object surface. In this paper, we demonstrate a quick grasp with contacting each finger simultaneously by proximity sensors on fingertips. In order to realize the grasp by optical proximity sensors, we introduce our reflectance estimation of the object surface and calibration of the sensor output. This approach uses only the proximity sensor output and a relative moving distance of the fingertip. It is unnecessary to add extra equipment or sensor for estimation and calibration. It is possible to achieve the grasp regardless of the reflectance of the object surface. In the experiment, we confirmed that the approach can be applied to surface with different reflection characteristics (iron plate, aluminum plate, paper: cylinder and plane ), and the hand can grasp a object with various reflectance surfaces (31.9∼76.1%) quickly with contacting each fingertip within 0.056s.

  • Integrated Control of a Multi-fingered Hand and Arm using Proximity Sensors on the Fingertips
    Keisuke Koyama; Yosuke Suzuki; Aiguo Ming; Makoto Shimojo
    2016 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND AUTOMATION (ICRA), IEEE, 4282-4288, 2016, Peer-reviwed, In this study, we propose integrated control of a robotic hand and arm using only proximity sensing from the fingertips. An integrated control scheme for the fingers and for the arm enables quick control of the position and posture of the arm by placing the fingertips adjacent to the surface of an object to be grasped. The arm control scheme enables adjustments based on errors in hand position and posture that would be impossible to achieve by finger motions alone, thus allowing the fingers to grasp an object in a laterally symmetric grasp. This can prevent grasp failures such as a finger pushing the object out of the hand or knocking the object over. Proposed control of the arm and hand allowed correction of position errors on the order of several centimeters. For example, an object on a workbench that is in an uncertain positional relation with the robot, with an inexpensive optical sensor such as a Kinect, which only provides coarse image data, would be sufficient for grasping an object.

  • Development of a Flexible Tail for Legged Robot
    Ryuki Sato; Shun Hashimoto; Aiguo Ming; Makoto Shimojo
    2016 IEEE INTERNATIONAL CONFERENCE ON MECHATRONICS AND AUTOMATION, IEEE, 683-688, 2016, Peer-reviwed, Some creatures can realize dynamic locomotions with a slender body by utilizing the dynamic effect by moving their whole body besides their legs. For example, some mammals moving by hopping with two legs at high speed and high efficiency have a tail as long as their body length. Their tails are composed of multi-joint and are exible. The dynamic effect by swinging their exible tails is useful for fast running and high jumping. In this paper, we develop a exible tail mechanism for two-legged robot inspired by the exibility of the animal tail. This tail is comprised of 6 linkages in series and the linkages are connected with elastic passive joints. First, the elasticity of tail joints and the motion of the tail base joint are designed by jumping simulations. To evaluate the effectiveness of the exible tail mechanism, jumping experiments have been conducted using the prototype of the two-legged robot with the exible tail as well as rigid tail. The results of these experiments show that the legged robot realized higher jumps with using the effect of swinging its exible tail.

    2016 IEEE/RSJ INTERNATIONAL CONFERENCE ON INTELLIGENT ROBOTS AND SYSTEMS (IROS 2016), IEEE, 2425-2430, 2016, Peer-reviwed, Cats have protractible claws to fold their tips to keep them sharp. They protract claws while hunting and pawing on slippery surfaces. Protracted claws by tendons and muscles of toes can help cats anchoring themselves steady while their locomotion trends to slip and releasing the hold while they retract claws intentionally. This research proposes a kind of modularized self-adaptive toe mechanism inspired by cat claws to improve the extremities' contact performance for legged robot. The mechanism is constructed with four-bar linkage actuated by contact reaction force and retracted by applied spring tension. A feasible mechanical design based on several essential parameters is introduced and an integrated Sole-Toe prototype is built for experimental evaluation. Mechanical self-adaption and actual contact performance on specific surface have been evaluated respectively on a biped walking platform and a bench-top mechanical testing.

  • Development of A Flexible Coupled Spine Mechanism For A Small Quadruped Robot
    Ryosuke Kawasaki; Ryuki Sato; Eiki Kazama; Aiguo Ming; Makoto Shimojo
    2016 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND BIOMIMETICS (ROBIO), IEEE, 71-76, 2016, Peer-reviwed, Quadruped animals realize dynamic motions such as fast running and high and long jumping with the utilization of the flexibility of their bodies. It is known that the motions of their front and rear legs couple with the flexion and extension of their spine when running or jumping. In recent years, quadruped robots inspired by cats and cheetahs have been developed. In our group, a small quadruped robot has been developed with leg mechanisms which consist of spring and damper systems inspired by bi-articular muscle-tendon complexes of animals. The robot is able to perform various motions such as walking, running and jumping. In this paper, flexibility features as in animal bodies are to be introduced to make the robot run fast and jump long (or high) by coupling the motions of their spine and legs. In our design, the flexion and extension of the spine are realized by a spine joint with a torsion spring, and the coupling to the front and rear legs has been realized by cables. Driving the scapula or hip joints causes flexion of the spine and stores the elastic energy in the spring. The extension of the spine with the spring assists in driving the scapula or hip joints. As a result, in the jump experiment, the robot with a flexible spine can realize longer jump distance than that by a robot with a rigid spine.

  • Grasping Strategy for Moving Object using Net-Structure Proximity Sensor and Vision Sensor
    Yosuke Suzuki; Keisuke Koyama; Aiguo Ming; Makoto Shimojo
    2015 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND AUTOMATION (ICRA), IEEE COMPUTER SOC, 1403-1409, 2015, Peer-reviwed, This study presents a robot-hand-arm system with high robustness and responsiveness by using a "Net-Structure Proximity Sensor." The sensor, which we have developed and specially designed for a robot hand, directly detects an object being to be grasped and outputs analog voltage signals according to the position/posture error between the robot hand and the object. It has been confirmed that the robot hand is able to quickly adjust to and grasp an unknown object by applying a feed-back control method based on the sensor signals. This paper focuses on the integration of the proximity-based feedback control to a commonly-used vision-based control. These sensors work in complementary manner: a vision sensor is available for planning an approaching path of a robot hand by detecting large area, and a Net-Structure Proximity Sensor enables the robot hand to adjust the approaching error before grasping and to improve the certainty of the grasping. Two objective velocities are derived independently by the sensors. By adding the velocities with considering the reliability of the sensor information, the robot hand becomes to be able to perform approaching and adjustment to the target object simultaneously.

    Takuma Uchida; Ryuki Sato; Aiguo Ming; Makoto Shimojo
    2015 IEEE INTERNATIONAL CONFERENCE ON MECHATRONICS AND AUTOMATION, IEEE, 1199-1203, 2015, Peer-reviwed, The realization of human-like dynamic motions by bipedal robots is still a challenge. One reason for this is that joints of bipedal robots are actuated with low backdrivability. In this paper, to improve backdrivability of the joints in a bipedal robot, a new mechanism of knee joint with continuously variable reduction ratio adaptive to load is proposed and a control method is also proposed according to the characteristic of the mechanism. A prototype of the bipedal robot using the designed knee joint with continuously variable reduction ratio adaptive to load has been developed. The effectiveness of the mechanism is shown by experimental results using the prototype.

  • Development of Robot Legs Inspired by Bi-articular Muscle-tendon Complex of Cats
    Ryuki Sato; Ichiro Miyamoto; Keigo Sato; Aiguo Ming; Makoto Shimojo
    2015 IEEE/RSJ INTERNATIONAL CONFERENCE ON INTELLIGENT ROBOTS AND SYSTEMS (IROS), IEEE, 1552-1557, 2015, Peer-reviwed, Within the limbs of typical animals, there exist bi-articular muscles crossing two joints. It is known that the bi-articular muscles of the felid play an important role in the locomotion. Also the muscle-tendon complex, composed of the gastrocnemius muscle and the Achilles' tendon that cross the knee joint and the ankle joint contributes much to the movements such as running and jumping particularly. Besides, because the muscle-tendon complex has the function for absorbing shocking, it is utilized for soft landing from high places. To achieve high performance for jumping and landing motion like cats, we are developing robot legs inspired by the bi-articular muscle-tendon complex of cats. The leg consists of hip, knee and ankle joints. For the knee and ankle joints, a four-bar linkage mechanism with one elastic linkage, in which the knee joint is driven by an electric rotary motor and the ankle joint is passive, is applied. By this mechanism, basic functions of the bi-articular muscle-tendon complex of felids like cats can be realized and the performance for jumping and landing can be improved. In this paper, the new leg mechanism is described. Moreover, a prototype of a pair of the hind legs of the quadruped robot using the new mechanism has been developed. The results of jumping and landing experiments are shown to validate the effectiveness of the mechanism.

  • Grasping Control Based on Time-To-Contact Method for a Robot Hand Equipped with Proximity Sensors on Fingertips
    Keisuke Koyama; Yosuke Suzuki; Aiguo Ming; Makoto Shimojo
    2015 IEEE/RSJ INTERNATIONAL CONFERENCE ON INTELLIGENT ROBOTS AND SYSTEMS (IROS), IEEE, 504-510, 2015, Peer-reviwed, Quick motion and soft touch control are important for autonomous grasping. To perform a grasping action, a hand must adjust its fingertips to match the object shape. It is also necessary to reduce the fingertip velocity on contact with the object. We propose a method of fingertip velocity control for fast approach and slow contact using proximity sensors installed on fingertips. The proposed control reduces the fingertip velocity at contact, decreasing the change of impulse force and thus making it appropriate for grasping soft or fragile objects. The proposed control uses time-to-contact (TTC), which is converted from sensor output. It is known that many animals, including humans, use TTC for collision avoidance. TTC represents the remaining time until collision considering the rate change of a control variable. We carried out grasping tests on various common objects using TTC. Experimental results show that the proposed control realizes fingertip alignment perpendicular to unknown shapes and surface objects and lowers the velocity at contact.

  • Development of A Small Quadruped Robot with Bi-articular Muscle-tendon Complex
    Eiki Kazama; Ryuki Sato; Ichiro Miyamoto; Aiguo Ming; Makoto Shimojo
    2015 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND BIOMIMETICS (ROBIO), IEEE, 1059-1064, 2015, Peer-reviwed, Hydraulic and pneumatic actuators are used as actuators of robots. They have large capabilities of instantaneous output, but with problems of increase in size and mass, and difficulty for precise control. In contrast, electromagnetic motors have better controllability, lower cost, and smaller size. However, in order to actuate robots, they are usually used with reducers which have high reduction ratio, and it is difficult to realize creature-like dynamic motions such as fast running and high jumping, due to low backdrivability of joints. To solve the problem, we have developed leg mechanisms, which consist of a spring and a damper inspired by bi-articular muscle-tendon complex of animals. The final target is to develop a quadruped robot which can walk, run fast and jump highly like a cat. A cat mainly uses its hind legs in jumping and front legs in landing. It implies that the hind legs play an important role in jumping, and that the front legs do in landing. For this reason, it is necessary to design different leg structures for front and hind legs. In this paper, we develop a new front leg mechanism suitable to a hind leg mechanism which was already made by our group, and make a small quadruped robot. As the result of experiments for dynamic motions, stable running trot at a speed of 3.5 kilometers per hour and forward jumping of 1 body length per jump have been realized by the robot.

    Wenjing Zhao; Aiguo Ming; Makoto Shimojo
    2014 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND AUTOMATION (ICRA), IEEE, 1474-1479, 2014, Peer-reviwed, Aiming to design a soft robotic fish with more natural, more flexible and high-performance movements through biomimetic method, we are developing a soft robotic fish with body/caudal fin (BCF) propulsion by using piezoelectric fiber composite (PFC) as actuator. Compared with conventional rigid robotic fish, the design and control of the soft robotic fish are difficult and hard to reveal its dynamic performances due to the large deformation of flexible structure and complicated coupling dynamics with fluid. That's why the design and control method of the soft robotic fish has not been established, and we need to study it by considering the interaction between flexible structure and fluid. In this paper, fluid-structural coupling analysis based on acoustics method is applied to consider the fluid effect and predict the dynamic responses of soft robotic fish using PFC in fluid. Basic driving and governing equations of soft robotic fish in the fluid are firstly described. Then the numerical acoustics coupling analysis is performed. The calculated results are congruent well with experiments on dynamic responses. Finally, based on this coupling method, a new prototype of soft robotic fish is proposed by optimization for improvement.

    2014 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND BIOMIMETICS IEEE-ROBIO 2014, IEEE, 1296-1301, 2014, Peer-reviwed, An in-depth understanding of passive bipedal walking is expected to contribute to the design of energy-efficient bipedal gaits and passivity-mimicking control laws. In this paper we investigate virtual passive bipedal walking in terms of generalized force and kinetic energy, and derive three characteristic equations which describe some essential mechanism of virtual passive bipedal walking and can be used to design a control law for completely passive bipedal walking on a level. We also show by simulation that the step length of passive bipedal walking is independent of the gravity, the step period is inversely proportional to the one-second power of the gravity, and the average speed of progression is proportional to the one-second power of the gravity.

    2013 IEEE INTERNATIONAL CONFERENCE ON MECHATRONICS AND AUTOMATION (ICMA), IEEE, 219-224, 2013, Peer-reviwed, Developing fish robots by biomimetic approach is a useful way to achieve more efficient, high-performance and fish-like motions. And it is very important to make the fish robots as soft as fishes. For this purpose, we are developing soft fish robots using flexible piezoelectric fiber composite (PFC) as actuators together with soft body structure. Comparing to the conventional rigid fish robot, the design and control of soft fish robots are difficult, because the coupling between the flexible continuum and fluid should be considered, which is very difficult to be solved due to large deformation and complicated dynamics. This is main reason why the design method for soft fish robots has not been established while many trial developments of soft fish robots have been done up to now. It motivates us to challenge the design and control problem of soft fish robots based on the analytical simulation with considering the coupling between flexible structure and fluid. In this paper, fundamental analysis for the design and control of soft fish robots using PFC is described. First, modeling of driving from input voltage of PFC to the displacement output of robot in the air is established and improved by comparing experimental results with simulation results. Next the method for structural design of fish robot is performed by modal analysis in the fluid. Finally, a new design of fish robot by the method is shown.

    2013 IEEE INTERNATIONAL CONFERENCE ON MECHATRONICS AND AUTOMATION (ICMA), IEEE, 855-860, 2013, Peer-reviwed, This paper proposes a design of common platform for small humanoid robots. There are many kinds of small humanoid robots for hobby or research. These humanoid robots are operated in different platforms developed by different developers. For this reason, the current development method is very inefficient. To solve the problem, it is necessary to develop common platform for all small humanoid robots. For this purpose, we are making a common platform for small humanoid robots on RT-Middleware which is used to build intelligent robotic systems. In this paper, first we investigated the requirements of the system to control motion-based humanoid robots.

  • Pre-shaping for various objects by the robot hand equipped with resistor network structure proximity sensors
    Keisuke Koyama; Hiroaki Hasegawa; Yosuke Suzuki; Aiguo Ming; Makoto Shimojo
    IEEE International Conference on Intelligent Robots and Systems, 4027-4033, 2013, Peer-reviwed, In this paper, we demonstrate a preliminary motion before grasping by a robot hand, for adjusting the object-fingertip distance and 2-axis postures simultaneously, using a Resistor Network Structure Proximity sensor (RNSP sensor). Through this motion (called 'pre-shaping') and the grasping of an object, the surface of each fingertip is brought into contact with the object surface so that in the next stage grasping can be undertaken. In the next stage, a force can be applied from the fingertips onto the object surface directly. The pre-shaping enhances the reliability of the feedback control for the after-contact tactile sensors. To realize the pre-shaping, we use fingertips equipped with RNSP sensors, which can detect the distance between the fingertip and the object, to determine the relative position between fingertips and an object. The RNSP sensor has a fast response (<
    1 [ms]) and simple connectivity (only 6 wires), and can be mounted easily. Additionally, a characteristics of the RNSP sensor output can be designed by the arrangement of the sensor elements. To perform the pre-shaping by simple sensor feedback control based on the configuration between the fingertip and object, we designed the RNSP sensor so that it had the appropriate characteristics for the pre-shaping. © 2013 IEEE.

    Journal of Robotics and Mechatronics, Fuji Technology Press, 25, 2, 316-323, 2013, Peer-reviwed, We have presented a slip sensor that uses pressure-conductive rubber to detect initial slip, but have not revealed the principle of high-frequency wave occurrence that is used by this detection. The wave-occurrence principle should be clarified in optimized slip sensor design, especially the properties of pressure-conductive rubber and the detector shape and for reducing individual differences in detection characteristics of the slip sensor. This paper discusses the wave-occurrence principle through a series of experiments and shows that localized fixing and peeling between pressure-conductive rubber and electrodes in the slip sensor configuration have important relation to the principle.

    MECHATRONICS, PERGAMON-ELSEVIER SCIENCE LTD, 22, 1, 13-23, Feb. 2012, Peer-reviwed, We report our studies of a new motion planning method for a two-link golf swing robot. We introduce two fundamental properties of manipulator dynamics: the time-reversal symmetry property and the pendulum property. The former is used to reverse the rest-to-point pre-impact swing (backswing and downswing) into a symmetric point-to-rest swing in time, and the latter is used to design a proportional-derivative plus gravity, joint and coupling torque compensation control algorithm to plan the reversed pre-impact swing and the point-to-rest follow-through swing. By using this method, accurate impact position and hitting speed control of the golf swing and low computational cost are achieved. The introduced properties hold true for general multi-revolute-joint planar manipulators and the proposed motion planning algorithm can be implemented on them too. (C) 2011 Elsevier Ltd.

  • A Unified Framework for Virtual Passive Bipedal Gait Generation
    C. Xu; A. Ming; M. Shimojo
    2012 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND AUTOMATION (ICRA), IEEE, 3141-3146, 2012, Peer-reviwed, It is well known a fine tuned unpowered biped machine can passively walk down a gentle slope. The in-depth understanding of the passivity is helpful to design more efficient bipedal gaits. In this paper, we investigate the principle mechanism of passive dynamic walking and propose a unified framework for virtual passive bipedal gait generation. The framework shows the physical system's kinetic energy varies inversely proportional to the imitated virtual system's potential energy. Based on this property we propose a kinetic energy tracking control law to realize virtual passive dynamic walking on any slopes in any virtual gravity fields. Numerical simulations are given to support our proposal.

    MECATRONICS REM 2012, IEEE, 161-168, 2012, Peer-reviwed, Robotic fishes using artificial muscle as actuators have been described recently. The purpose of this work is to develop a flexible robotic fish using the piezoelectric fiber composite (PFC). To achieve the good flexibility and mobility of the robotic fish, we proposed a simple and compact structure. The load simulation method of piezoelectric actuator was employed to improve the fish's movement performance and swimming efficiency. By the analysis of the driving characteristics of the PFC, the robot structure with symmetrical distribution was designed based on the caudal fin propulsion mode. This structure was verified reasonable in the theoretical and simulation method. The dynamic characteristics of this underwater robot were both analyzed through the experiments and numerical analysis of Finite Element Method (FEM). The calculated results were congruent well with the experiment measurements of the prototype. Relatively high swimming speed was achieved during the experimental tests for a prototype. This indicated the numerical methods can be applied in the structural optimization and dynamic analysis of the robotic fish. More information will be available for the fluid-structure interaction analysis in future.

    Seiichi Teshigawara; Takahiro Tsutsumi; Satoru Shimizu; Yosuke Suzuki; Aiguo Ming; Masatoshi Ishikawa; Makoto Shimojo
    2011 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND AUTOMATION (ICRA), IEEE, 1097-1102, 2011, Peer-reviwed, Tactile sensors for slip detection are essential for implementing human-like gripping in a robot hand. In previous studies, we proposed flexible, thin and lightweight slip detection sensors utilizing the characteristics of pressure-sensitive conductive rubber. This was achieved by using the high-frequency vibration component generated in the process of slipping of the gripped object in order to distinguish between slipping of the object and changes in the normal force. In this paper, we design a slip detection sensor for a multi-fingered robot hand and examine the influence of noise caused by the operation of such a hand. Finally, we describe an experiment focusing on the adjustment of the gripping force of a multi-fingered robot hand equipped with the developed sensors.

    Hiroaki Hasegawa; Yosuke Suzuki; Aiguo Ming; Masatoshi Ishikawa; Makoto Shimojo
    Journal of Robotics and Mechatronics, Fuji Technology Press, 23, 3, 328-337, 2011, Peer-reviwed, Occlusion in several millimeters from an object to be grasped made it difficult for a vision-sensor-based approach to detect relative positioning between this object and robot fingers joint grasping. The proximity sensor we proposed detects the object at a near range very effectively. We developed a thin proximity sensor sheet to cover the 3 fingers of a robot hand. Integrating sensors and hand control, we implemented an objecttracking controller. Using proximity sensory signals, the controller coordinates wrist positioning based on palm proximity sensors and grasping from fingertip sensors, enabling us to track and capture moving objects.

    Masahiro Wada; Aiguo Ming; Makoto Shimojo
    2011 IEEE International Conference on Mechatronics and Automation, ICMA 2011, 1822-1827, 2011, Peer-reviwed, This paper proposes a new motion planning method for a hyper-dynamic robot which aims at realizing the motion control skills exhibited by professional golfers by a dexterous robot. The robot has similar distribution of actuators' capability to that of human, which is compact but requires dynamically-coupled driving for high speed motion. For such a robot with strong coupling and nonlinearity, to realize a motion including multi-boundary conditions, motion planning is very difficult. As a new method for the motion planning, the motion planning method using reinforcement learning is proposed in this paper. Simulation results show the effectiveness of the proposed motion planning method. © 2011 IEEE.

    2011 IEEE/RSJ INTERNATIONAL CONFERENCE ON INTELLIGENT ROBOTS AND SYSTEMS, IEEE, 1954-1961, 2011, Peer-reviwed, This paper presents a proximity sensor for recognizing an object in 360 degrees all around with response time only 1[ms]. The sensor applies an unique design of analog net-structure circuit, which enables all-face mounting on various peripheries and fast-response/simplification of information processing. Thus, the sensor is especially available for avoiding sudden contact with rapidly approaching objects for mobile robots, robot arms, robot hands, and other robotic systems. In this paper, the structure and the detecting principle of the sensor are firstly described, then, its detection property is tested by experiments. The result shows that the sensor recognizes the angle of the nearby object with accuracy of 3[deg]. Furthermore, as practical use of the sensor, a large size model is produced for a mobile robot to achieve omni-directional sensing. By using the application model, two detection methods are discussed on situations where the number or the positions of the nearby objects differs.

    International Journal of Mechatronics and Automation, 1, 3-4, 181-189, 2011, Peer-reviwed, The high precision gears are strongly required for advanced motion and power transmission. And the improved evaluation technology for the precision gears is becoming indispensable. Moreover, the reliability of the measured value became important when the accuracy of the gear becomes high, and the establishment of the traceability system has been needed. For the establishment of the traceability system, the higher precision gear measuring machine (GMM) with lower uncertainty is expected to contribute to improve gear calibration uncertainty. For the purpose, a new concept of the high precision GMM was proposed from analysing the problems of the conventional GMM. A prototype of the high precision GMM using the direct drive mechanism has been developed. And the high measurement capability of the developed GMM was verified by the evaluation method using the standard deviation of the measured form deviation. © 2011 Inderscience Enterprises Ltd.

But, in the boundary area of a non-contact phase and a contact phase, there are problem that lack of sensor information because the influence of occlusion comes up to surface. We devise to introduce the proximity sensor in this area. And we call the robot hand which is equipped with proximity, tactile and slip sensor "intelligent robot hand".

  • High Sensitivity Initial Slip Sensor for Dexterous Grasp

    2010 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND AUTOMATION (ICRA), IEEE, 4867-4872, 2010, Peer-reviwed, Slip-detecting tactile sensors are essential for achieving human-like gripping motion with a robot hand. In previous research, we developed a flexible, thin and lightweight slip sensor that exploits the characteristics of pressure conductive rubber. However, using this sensor, it was difficult to distinguish between object slip and a change in the normal force. Therefore, in the present research, we investigated a method for identifying object slip by analyzing the frequency components of the output signal from the sensor. As a result, we found that high-frequency components of 1 kHz or more are included in the complex voltage signal generated by object slip. Therefore, by using this high-frequency component, we developed a simple sensor that distinguished between both contact and initial slip with high sensitivity.

    JOURNAL OF INTELLIGENT & ROBOTIC SYSTEMS, SPRINGER, 56, 3, 277-299, Oct. 2009, Peer-reviwed, In this paper we discuss our simulation and empirical study of a golf swing motion controller for a two-link golf swing robot. We distinguish two variants of the whole golf swing termed as hitting problem and stopping problem. For the hitting problem arising from backswing and downswing, we map the task into the output of a target dynamic system-a harmonic oscillator-under energy control. For the stopping problem that arises from follow-through, we propose a Proportional plus Gravity and Coupling Torque Compensation (PGCTC) feedback controller. Preliminary simulation study shows the proposed controllers solve the hitting problem and the stopping problem respectively. The controllers are implemented on a physical robot. Experimental results indicate the robot is able to perform desired golf swing-backswing, downswing, and follow-through. We also give a preliminary analysis on the proposed method to understand its merits and weaknesses.

    ICRA: 2009 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND AUTOMATION, VOLS 1-7, IEEE, 1311-+, 2009, Peer-reviwed, Even with the eyes closed, humans are able to grip an object with minimal force without such information as the coefficient of friction or the weight. Tactile sensors capable of detecting slippage are necessary for this gripping action to be realized in a robot hand. Heretofore, many slip sensors were developed and produced, but there was not a slip sensor of simple structure practical for installation on fingertips of a robot hand. Therefore, we propose a low-profile/lightweight slip sensor of simple structure. The special properties of pressure conductive rubber are utilized as a detection device in this sensor. In this paper, we discuss the results of trial manufacture and of slip detection property testing of this sensor. Moreover, we will report the results of slip prevention experiments by this prototype slip sensor, and indicate that the pressure conductive rubber is promising as a material of slip sensor.

    ICIA: 2009 INTERNATIONAL CONFERENCE ON INFORMATION AND AUTOMATION, VOLS 1-3, IEEE, 918-+, 2009, Peer-reviwed, Recently, there are many needs for small tracking camera systems to be mounted on mobile platforms, such as bikes, cars, etc., to tracking some targets stably in a perturbation environment. To meet the needs, a small tracking camera system has been developed by authors. The purpose of the tracking camera system is both to stabilize the camera and to track the target simultaneously. The system consists of three axes driven by DC motors with encoders, to form velocity and position control loop. Outside the loop, another position control loop is composed based on the integration of both rate gyro and inclinometer by a designed filter, to stabilize the camera. And besides the two loops, another position compensation loop is formed by introducing the camera position information, to track the target. This paper describes the system configuration, the design of controller as well as sensor systems, and the experimental results on the tracking performance.

    2009 IEEE INTERNATIONAL CONFERENCE ON MECHATRONICS AND AUTOMATION, VOLS 1-7, CONFERENCE PROCEEDINGS, IEEE, 2805-2810, 2009, Peer-reviwed, This paper reports our recent results on the motion control of cooperative transportation by two mobile manipulators following a reference trajectory on the slope. We propose a cooperative control algorithm which is divided into two steps. In the first step, the mobile manipulators regulate their postures to keep themselves away from falling using their redundant Degree-Of-Freedom. If the robots still cannot keep stable, then in the second step, both robots adjust their forces acting on the transported object to avoid falling. Simulation results are given to validate the proposed method.

    2009 IEEE SENSORS, VOLS 1-3, IEEE, 988-988, 2009, Peer-reviwed, Slip detecting tactile sensors are essential to achieve a human-like gripping motion with a robot hand. In previous researches, we have proposed flexible, thin and lightweight slip sensor utilizing characteristics of pressure conductive rubber. However, It was hard for this sensor to distinguish between the object slip and the normal force change. Therefore, we consider the separative method using high frequency elements generated by object slipping. In this paper, we design the information processing method and developed the sensor detecting both contact and initial slip in high sensitivity and a simple composition.

    2008 PROCEEDINGS OF SICE ANNUAL CONFERENCE, VOLS 1-7, IEEE, 858-863, 2008, Peer-reviwed, To achieve a human like grasping with a multi-fingered robot hand, the grasping force should be controlled without using information from the grasped object such as its weight and friction coefficient. In this study, we propose a method for detecting the slip of a grasped object using the force output of Center of Pressure (CoP) tactile sensors. CoP sensors can measure the center position of a distributed load and the total load applied on the surface of the sensor, within 1 ms. These sensors are arranged on the fingers of the robot hand, and their effectiveness as slip detecting sensors is confirmed in tests of slip detection during grasping. Finally, we propose a method for controlling grasping force to resist tangential force applied to the grasped object using a feedback control system with the CoP sensor force output.

    2008 IEEE/ASME INTERNATIONAL CONFERENCE ON ADVANCED INTELLIGENT MECHATRONICS, VOLS 1-3, IEEE, 955-960, 2008, Peer-reviwed, We developed several underwater robots by using Macro Fiber Composite(MFC), a new type of piezo-electric actuator with the merits of being soft and capable of large displacement, developed by NASA recently. MFC is made by processing PZT into a fiber-like state, hence yielding better flexibility, and structural actuation is possible by pasting it to thin structures since it is covered by polyimide film. Utilizing MFC's characteristics of being thin and flexible, meandering motion observed in underwater creatures such as fish is possible by generating progressive waves for propulsive force. Hence, a space-saving, effective mechanism capable of underwater movement can be achieved. Furthermore, in addition to forward locomotion, whirling motion and locomotion direction switching by using multiple MFCs actuators has been realized also.

    ADVANCED ROBOTICS, VSP BV, 21, 11, 1231-1252, Nov. 2007, Peer-reviwed, In this paper, robust force/motion control strategies are presented for mobile manipulators under both holonomic and non-holonomic constraints in the presence of uncertainties and disturbances. The proposed control strategies guarantee that the system motion converges to the desired manifold with prescribed performance and constraint force control is developed using the passivity of hybrid joints rather than force feedback control. Experiment results validate that not only the states of the system asymptotically converge to the desired trajectory, but also the constraint force asymptotically converges to the desired force.

  • Development and control of compliant hybrid joints for human-symbiotic mobile manipulators
    Zhijun Li; Jun Luo; Hing Xi; Aiguo Ming
    International Journal of Advanced Robotic Systems, InTech Europe, 4, 1, 27-34, 2007, In this paper, we develop a robot with the ability to secure human safety in human-robot collisions arising in our living and working environments. The human-symbiotic service robot using compliant hybrid joints realizes human safety, absorbs impact force, and fulfills task. In unexpected or expected collisions with human, the arising impulse force is attenuated effectively by the proposed physical model. Owing to the displacement of the links, several recovery controls have been developed for the end-effector to maintain its desired task position after the collision. The force attenuation property has been verified through collision simulations and experiments in that the capability of the proposed passive arm in overcoming the limitations of active compliance control has been demonstrated.

    2007 IEEE INTERNATIONAL CONFERENCE ON INTEGRATION TECHNOLOGY, PROCEEDINGS, IEEE, 568-+, 2007, Peer-reviwed, We are aiming to improve the performance of a passive vibration isolator for ship-mounted antennas by designing the parameters of the isolator including nonlinear springs and dampers. It is known that a passive isolator has an inevitable problem, trade-off between minimizing the magnification of resonance and suppressing the magnifications in the region of high-frequency into lower levels. To solve this problem, we introduce a nonlinear model with more design parameters and adopt an optimization method, that is, minimizing the evaluation function consisting of two terms which indicate effects on resonant magnification and vibration isolation. By, this approach, several available solutions, which can improve vibration isolation performance while with reduced magnification of resonance, are obtained.

  • Design for high dynamic performance robot based on dynamically coupled driving and joint stops
    C. Xu; A. Ming; K. Mak; M. Shimojo
    INTERNATIONAL JOURNAL OF ROBOTICS & AUTOMATION, ACTA PRESS, 22, 4, 281-293, 2007, Peer-reviwed, A new design approach is proposed for high dynamic performance robots, such as robots performing high-speed dynamic motions. This method is based on the utilization of dynamically coupled driving and joint stops. In the method, the dynamic performance index (DPI) formulated by the desired maximum motion specifications and the boundary conditions on initial/final configurations are combined to form a design index (DI) first. Then a dexterous mechanism consisting of very light actuators and links is initially designed under an assumption of utilizing dynamically coupled driving and joint stops. By increasing the load capabilities of the actuators step by step, an iterative process of searching for the solution of DI=0 with minimal torque needs is implemented to validate and improve the initial design. This process yields a robot that is lighter than conventional robots and capable of performing dynamic motions more efficiently by utilizing dynamically coupled driving and joint stops. Based on the method, a two-link golf swing robot performing high-speed swings is designed. Simulation results indicate the method can reduce the needs for the torque and power as compared with conventional design methods. The experiment clearly illustrates the merits of the method.

    Aiguo Ming; Shinya Furukawa; Teppei Teshima; Makoto Shimojo; Makoto Kajitani
    MECHATRONICS, PERGAMON-ELSEVIER SCIENCE LTD, 16, 7, 443-449, Sep. 2006, Peer-reviwed, The motion control skill in human hyper dynamic motions, especially in ultra high speed motions, is being investigated by the authors toward a realization of hyper dynamic manipulation by robots. As a case study, a new golf swing robot, consisting of an actuated joint and a passive joint with a mechanical stopper, has been developed by us. To improve the accuracy of the motion, learning control using ANN is introduced to shadow swing motion and the swing motion of hitting a ball, and its effectiveness has been shown by experiments. Since the model used in the method depends on the swing conditions, it is difficult to adapt the same model to all conditions. To improve the versatility of the learning control method, a recurrent ANN as a model with versatility is adopted to derive the model of direct dynamics of such strongly coupled, non-linear, non-holonomic and hybrid system. And a control method based on learning and motion generation by using the model is proposed and implemented to the golf swing robot prototype. In this paper, the method for adopting the recurrent ANN and implementing the learning control is described, and experimental results are shown. (C) 2006 Elsevier Ltd. All rights reserved.

  • Robust Motion/Force control of holonomic constrainted nonholonomic mobile manipulators using hybrid joints
    Jun Luo; Zhijun Li; Aiguo Ming; Shuzhi Sam Ge
    WCICA 2006: SIXTH WORLD CONGRESS ON INTELLIGENT CONTROL AND AUTOMATION, VOLS 1-12, CONFERENCE PROCEEDINGS, IEEE, 408-+, 2006, Peer-reviwed, In this paper, robust force/motion control strategies are presented for mobile manipulators under both holonomic and nonholonomic constraints in the presence of uncertainties and disturbances. Robust controls are proposed based on a simplified dynamic model, the defined reference signals and the mixed tracking errors. The proposed control strategies guarantee that the system motion converges to the desired manifold with prescribed performance. Constraint force control is developed, which does not utilize force feedback control but is based on the passivity of hybrid joint. Experiment results validate not only the states of the system asymptotically converge to the desired trajectory but also the constraint force asymptotically converges to the desired force.

    Tomoari Maruyama; Chunquan Xu; Aiguo Ming; Makoto Shimojo
    2005 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND BIOMIMETICS, IEEE, 77-+, 2006, Peer-reviwed, A new golf swing robot to simulate human's motion has been developed by authors. The basic design concept of the robot is to realize high speed swing motion while by a smart structure, just like human. By the concept, the robot consists of a shoulder joint with powerful direct-drive motor and a wrist joint with small direct-drive motor. And for the reason, swing motion at high speed should be realized by a skill of motion control, so called dynamically-coupled driving, to compensate the lack of driving capability in the wrist joint. This paper deals with the motion control of the robot. First, a new model of golf swing robot with considering the flexibility of golf club is established and all parameters are identified by experiments. According to the new model, trajectories for different criteria are generated and implemented to the robot. Experimental results show high accuracy of the motion control.

  • Dynamic performance enhancement design of robot based on dynamically-coupled driving and joint stop
    Chunquan Xu; Aiguo Ming; Makoto Shimojo
    2006 IEEE CONFERENCE ON ROBOTICS, AUTOMATION AND MECHATRONICS, VOLS 1 AND 2, IEEE, 659-+, 2006, Peer-reviwed, A new design method based on the utilization of dynamically-coupled driving and joint stops is proposed for high dynamic performance robots, such as the robot performing highspeed dynamic motions. In the method, the desired dynamic performance and the boundary conditions of the dynamic motion are combined to be a design index (DI) first. Then the robot is initially designed by selecting light actuators and links under an assumption of utilizing dynamically-coupled driving and joint stops. By increasing the actuator capabilities step by step, an iterative process of minimizing DI is implemented to yield a robot that is lighter than conventional robots and capable of performing dynamic motions more efficiently by utilizing dynamically-coupled driving and joint stops. Based on the method, a two-link golf swing robot performing high-speed swings is designed. Simulation results indicate the method can reduce the needs for the torque and power as compared with conventional design methods. The experiment illustrates the dynamically-coupled driving and the joint stops can be used.

    IEEE-ASME TRANSACTIONS ON MECHATRONICS, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 10, 1, 87-97, Feb. 2005, Peer-reviwed, A new kind of the rotary encoder based on the magneto-optical (MO) storage is proposed. Using the MO methods, a small high-precision high-response rotary encoder can be realized. High precision is achieved by a two-stage process in which the code disk is firstly written using the direct transfer recording, and then rewritten using the corrections based on the measured errors. The systems for writing to, reading from, and evaluating the MO encoder are developed, with the optimal MO encoder reading and writing parameters determined experimentally. A trial MO encoder with a resolution of 9000 pulses/revolutions is created directly from a reference encoder, delivering an accuracy of approximately 2.8 in. The maximum resolution and response frequencies achieved are 18000 p/r and 400 kHz. After the corrected transfer recording, accuracies of 1.3 in at a resolution of 2250 p/r and 1.7 in at 9000 p/r are achieved.

    ZJ Li; AG Ming; N Xi; ZX Xie; JG Gu; M Shimojo
    2005 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND AUTOMATION (ICRA), VOLS 1-4, IEEE, 4037-4043, 2005, Peer-reviwed, a human-symbiotic safe mobile manipulator with nonholonomic constraint is described to realize human safety, impact force absorbing and task fulfillment. The robot consists of an arm covered with soft materials and hybrid joints, which can be put into active or passive mode as needed. In an unexpected or expected collision with human, the arising impulse force is attenuated effectively by the physical model formed with the hybrid joint and the soft material. Owing to the displacement movement of the link when the joint is passive, a recovery control algorithm has been developed for the end-effector to maintain its desired task position after the collision. Simulation and experiment results confirm that the proposed physical model is suitable for robot working in the human-robot symbiotic environment and the control method are useful for robot's task fulfillment.

    INTERNATIONAL JOURNAL OF ROBOTICS & AUTOMATION, ACTA PRESS, 20, 4, 260-270, 2005, Peer-reviwed, This paper presents a safe arm using compliant hybrid joints for human-friendly service robots, which realizes human safety, absorbs impact force, and provides task fulfillment. The robot is composed of links covered with soft materials and hybrid joints, which can be put into active or passive mode as needed. In an unexpected or expected collision with a human, the arising impulse force is attenuated effectively by the proposed physical model, which is developed with the hybrid joints and the soft covering. Owing to the displacement of the links when the joint is passive, a recovery control algorithm has been developed for the end-effector to maintain its desired task position after the collision. The force attenuation property has been verified through collision experiments in that the capability of the proposed passive arm in overcoming the limitations of active compliance control has been demonstrated. Simulation results also showed that the proposed control method is useful for robot's task fulfillment.

  • Optimal trajectory generation for manipulator with strong nonlinear constraints and multiple boundary conditions
    CQ Xu; AG Ming; M Shimojo
    IEEE ROBIO 2004: Proceedings of the IEEE International Conference on Robotics and Biomimetics, IEEE, 192-197, 2004, Up to now, the research work about optimal trajectory generation mainly focuses on such motion planning with boundary conditions of specified initial and final configurations. Multiple boundary conditions are seldom taken into account. This paper explores the motion planning method for hyper dynamic manipulation with multiple boundary conditions of initial, final and middle configurations and strong nonlinear constraints derived from active torque limitation and joint stop, and B-spline based optimal torque trajectory generation method is proposed by authors. By transforming the torque limitation constraints into a series of linear limitations for the coefficients of B-spline, and by using SQP optimization algorithm, optimal solutions are obtained with high convergence. Numerical experiments show the proposed method has superior numerical stability and high optimization accuracy in dealing with the optimal motion planning problem with strong nonlinear constraints and multiple boundary conditions.

  • A new golf swing robot to simulate human skill-accuracy improvement of swing motion by learning control
    A Ming; M Kajitani
    MECHATRONICS, PERGAMON-ELSEVIER SCIENCE LTD, 13, 8-9, 809-823, Oct. 2003, Peer-reviwed, A new golf swing robot to simulate human skill of motion control with one actuated joint and one passive joint has been developed by authors. Because of the special mechanism with non-holonomic constraint of the robot and the motion of high speed, it is difficult to realize an accurate swing motion by usual feedback control. To solve the problem, this paper describes a control method using mainly feedforward control based on an approximate inverse dynamics model (IDM) close to the real system. The approximate IDM is composed of a simple IDM and a compensation IDM represented by a neural network and is to be improved by learning in doing. By this method, most part of control input is shifted from feedback control to feedforward control and an accurate swing can be realized. The method is implemented to the prototype of golf swing robot, and experimental results of shadow swing before and after learning control show the effectiveness of the proposed learning control.

The operational principle of the sensor is reflective intensity based modulation. Different reflection patterns have been considered, and the analyses of the modulation characteristics on specular reflection and diffuse reflection assumption are carried out, keeping in mind that the modulation properties of a real sensor lie between those of the two types of reflection patterns. A prototype sensor has been developed and preliminary experiment has been done. The results show that the sensor is feasible for application and valuable for further development.

    K Tobita; T Ohira; M Kajitani; C Kanamori; A Ming; M Shimojo; S Kawamoto
    PROCEEDINGS OF THE 3RD CHINA-JAPAN SYMPOSIUM ON MECHATRONICS, CHINESE INSTITUTE ELECTRONICS, 128-133, 2002, We propose a new kind of rotary encoder based on a magneto-optical storage method. By using this method, a rotary encoder with small size, high precision and response can be realized. High precision can be achieved with the ability for re-recording by using the transfer recording with error correction method. The method is as follows. Firstly, an initial recording is made directly from the reference encoder and angle position errors of MO encoder are measured. Correcting values to cancel errors are calculated based on Fourier analysis. Finally, MO encoder is re-recorded with the correcting values after erasing. The following issues are described: (1) A device for recording, playback and evaluation of MO encoder has been developed. (2) MO encoder made for trial purposes was recorded by 2250 p/r (pulses/revolution) directly from the referential encoder. Accuracy of about 2.5" and reproducibility of 0.079" were achieved. (3) As a result of experiments for transfer recording with error correction, an accuracy of 1.3" for 2250 p/r and 1.7" for 9000 p/r was achieved.

    A Ming; M Kajitani; C Kanamori; J Ishikawa
    JSME INTERNATIONAL JOURNAL SERIES C-MECHANICAL SYSTEMS MACHINE ELEMENTS AND MANUFACTURING, JAPAN SOC MECHANICAL ENGINEERS, 44, 1, 196-202, Mar. 2001, Peer-reviwed, The characteristics of angle transmission mechanisms exert a great influence on the servo performance in the robotic or mechatronic mechanism. Especially, the backlash of angle transmission mechanism is preferable the small amount. Recently some new types of gear reducers with non-backlash have been developed for robots. However, the measurement and evaluation method of the backlash of gear trains has not been considered except old methods which can statically measure at only several meshing points of gears. This paper proposes an overall performance testing method of angle transmission mechanisms for the mechatronic systems. This method can measure the angle transmission error both clockwise and counterclockwise. In addition the backlash can be continuously measured in all meshing positions automatically. This system has been applied to the testing process in the production line of gear reducers for robots, and it has been effective for reducing the backlash of the gear trains.

    Proceedings of the IEEE International Conference on Systems, Man and Cybernetics, 1, 359-364, 2001, To construct a practical system using a mobile manipulator, a new mobile manipulator with exchangeable active/passive joints has been developed by authors. In the mobile manipulator, passive joints play an important role in absorbing the mobile positioning error and reducing the internal force passively. By utilizing the exchangeable active/passive joints, a control algorithm for automatic insertion of a long pipe based only on the angular information of the passive joints is proposed. By implementing the algorithm to the mobile manipulator, the insertion task was performed successfully. The proposed control algorithm is described and the experimental results are shown in this paper.

    Kazuteru Tobita; Takayuki Ohira; Makoto Kajitani; Chisato Kanamori; Aiguo Ming
    Seimitsu Kogaku Kaishi/Journal of the Japan Society for Precision Engineering, 67, 12, 1976-1980, 2001, The feasibility for fabricating a magneto-optical rotary encoder (MO encoder) has been shown in our previous paper. In this paper, an error corrected recording method to improve accuracy of the MO encoder is described. The recording method utilizes one feature of MO encoder, that is, ability for re-recording. First, an initial recording is made directly from referential encoder to MO encoder and angular errors of the MO encoder are measured. According to the errors, correcting values for canceling the errors are calculated based on Fourier components analysis. Finally, the MO encoder is re-recorded by the correcting values after erasing the initial recording. As the result of experiments, an accuracy of 1.3" for 2250 pulse/rev. and 1.7" for 9000 pulse/rev. was achieved by using the error corrected recording method. © 2001, The Japan Society for Precision Engineering.

    Seimitsu Kogaku Kaishi/Journal of the Japan Society for Precision Engineering, 67, 1, 96-100, 2001, In this paper, a new kind of rotary encoder based on magneto-optical storage method is proposed. By using this method, a rotary encoder with small size, high accuracy and high response can be realized. MO encoder is more advantageous than a magnetic scale and optical encoder according to its high response and its high accuracy, respectively. High accuracy can be achieved by rerecording, therefore the error is corrected. Following issues are described: (1) A device for record, playback and evaluation of accuracy of MO encoder has been developed. (2) A necessary condition for record and playback for MO encoder was experimentally derived. (3) The MO encoder made for trial purposes was recorded by 2250 pulses per revolution directly from the referential encoder, as a result, accuracy of 2.5" and reproducibility of 0.079" were achieved. © 2001, The Japan Society for Precision Engineering.

  • Generation of optimal trajectory for real system of an under-actuated manipulator
    N Luan; A Ming; M Kajitani
    2001 IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND AUTOMATION, VOLS I-IV, PROCEEDINGS, IEEE, 3308-3313, 2001, Peer-reviwed, Trajectory of an under-actuated manipulator is usually generated according to both kinematics and dynamics of the manipulator, different to that of conventional manipulator. For this reason, another important problem in trajectory generation for the real system of an under-actuated manipulator is the realizablity of trajectory. That is, the real trajectory by real system may differ greatly from the trajectory generated from the dynamics model because there always exist errors in dynamic model and feedback control is less effective in under-actuated manipulator. A method for generation of optimal trajectory for real system of an under-actuated manipulator with non-holonomic constraint is proposed in this paper, By this method, dynamics model of real system can be improved by learning and optimal trajectory is generated according to the model improved sequentially. The effectiveness of the method has been confirmed by experiment with a golf swing robot. Method, implementation and experimental results of the control method are described in this paper.

    Seimitsu Kogaku Kaishi/Journal of the Japan Society for Precision Engineering, Japan Society for Precision Engineering, 67, 7, 1101-1107, 2001, Peer-reviwed, In our previous work, robust control structure based on disturbance observer for a fast and precise fine motion mechanism has been proposed. The functionality of the controller was verified using one axis of precise X-Y table combined with-one axis fine motion mechanism. As a further step in this paper, the approach is extended to two-axes fine motion mechanism with a SCARA robot as a real system to realize the final purpose, that is, the development of high-precision mounting robot. First, the paper introduces a high performance robot system based on a SCARA robot coupled with a fine motion mechanism which was developed in our laboratory. Second, the paper presents a control scheme that enables correction of possible offsets of the end-effector relative to the target and compensation of the oscillations at the end-point. Finally, experimental results show significant improvements in end-point accuracy and settling time achieved by the novel configuration of the coarse/fine robotic system. As a result, a repeatability (3σ) less than 2 μm and the CP positioning error (3σ) less than 4.0 μm were achieved by the coarse/fine robotic system.

  • Rapid obstacle sensing using mobile robot sonar
    V. Masek; M. Kajitani; A. Ming; L. V. Vlacić
    Mechatronics, 10, 1-2, 191-213, 2000, Peer-reviwed, This paper introduces rapid obstacle sensing using mobile robot sonar (ROSUM) a new method of applying simultaneous ultrasonic firing in environmental scanning. ROSUM focuses on treating undesirable crosstalk data with a heuristic pattern classification technique. In addition, least square curve fitting is applied to estimate bearing angles to the echoes' reflecting points which partially eliminates the problem of sonar's poor directionality. ROSUM enables full panorama scanning to be performed more rapidly then error eliminating rapid ultrasonic firing (EERUF), currently the most rapid method available. This makes ROSUM suitable for fast mobile robots navigating in dynamic environments since the system can detect obstacles which suddenly appear in the robot's path, and which may not be detected by the low-frequency scans in time for the robot to safely avoid them. Criteria for sonar ring design enabling multi-wave superposition to attain a quasi-homogenous sonar beam intensity pattern are also outlined. ROSUM has been implemented and tested in a specular office-like environment using a mobile robot. As a result, obstacle detection was performed not only faster, but also more accurately in comparison to conventional methods.

    Seimitsu Kogaku Kaishi/Journal of the Japan Society for Precision Engineering, Japan Society for Precision Engineering, 66, 10, 1583-1589, 2000, Peer-reviwed, This paper presents a controller structure for a fast and precise fine positioner which can be attached to the end-effector of a classical industrial robot for assembly tasks. The overall control system consists of three elements: a position loop feedback controller, a feedforward controller, and a disturbance observer for the position loop. A useful method for compensating for the asymmetry and non-linearities of the piezoelectric based system is used as the first step in the design process. The robust feedback controller based on the disturbance observer compensates for external disturbances mainly from the coarse positioner. Precise tracking is achieved by the feedforward controller. Experimental results are presented to demonstrate performance improvement obtained by each element in the proposed robust structure.

    Masek, V; M Kajitani; A Ming; L Vlacic
    INTERNATIONAL JOURNAL OF THE JAPAN SOCIETY FOR PRECISION ENGINEERING, JAPAN SOC PRECISION ENG, 32, 3, 207-212, Sep. 1998, Peer-reviwed, This paper describes a new method of scheduling multiple Ultrasonic Range Sensors (URSs) mounted on a sonar ring designed for fast mobile robot obstacle detection. This method employs simultaneous firing of all on-board URSs operating on the same frequency where false range data caused by interference among multiple URSs are consequently rejected from scan data on the basis of crosstalk modeling. This task is performed by simulating a simple backpropagation neural network. The new method allows full panorama scanning six to ten times faster than those customary in conventional applications so that mobile robot can detect obstacles which appear in its path suddenly, and which may not be detected by the low-frequency scans in time for the robot to safely avoid them. The presented experimental results show the fundamental functionality of the new method.

    A Ming; M Kajitani; T Higuchi
    INTERNATIONAL JOURNAL OF THE JAPAN SOCIETY FOR PRECISION ENGINEERING, JAPAN SOC PRECISION ENG, 29, 4, 337-342, Dec. 1995, The wire parallel mechanism is the parallel mechanism in which wires are used as legs instead of links. In our previous work, wire parallel mechanisms had been classified into CRPM (completely restrained positioning mechanism) and IRPM (incompletely restrained positioning mechanism), and basic design conditions for CRPM were given. Besides the basic design conditions, the simplification of direct kinematics, which is a common problem of the parallel mechanism, stiffness and workspace problems, which are major problems of the wire parallel mechanism, must be considered when designing the mechanism. In this paper, first the concept of the positioning mechanism using wires is extended to a wire parallel mechanism. Then the simplification of direct kinematics using the features of the wire parallel mechanism is discussed. Moreover, stiffness of the mechanism is investigated to provide hints for the design of the wire parallel mechanism.

As an application of the obtained results for mechanism design and proposed control scheme, we developed a prototype of planar Completely Restrained Positioning Mechanism using wires, in which four wires are used to realize three D.O.F.(two translational and one rotatory) positioning in a plane. To control this prototype, we constructed a practical controller by software servo with optimal tension compensation. As the results of experiments for positioning capability, the PTP repeatability accuracy of +/-0.07mm with maximum velocity of about 1m/s, and the path(circle) accuracy of +/-0.44mm are obtained. Those results show that the mechanism is available in practice.

    A MING; T HIGUCHI
    INTERNATIONAL JOURNAL OF THE JAPAN SOCIETY FOR PRECISION ENGINEERING, JAPAN SOC PRECISION ENG, 28, 2, 131-138, Jun. 1994, Peer-reviwed, Recently it becomes more and more important to use very light elements in a mechanism, such as flexible arm in space robot, to reduce the energy consumed by the elements themselves. This paper deals with the multiple degree-of-freedom (D.O.F.) positioning mechanism directly driven by thin, light wires. In which the positioning object is manipulated by multiple wires and positioned by controlling the length of each wire. Because of the flexibility of wire, the mechanism design and control are different from any other mechanisms driven by rigid element. In this paper, a general, systematic discussion about the properties, design, control and purpose of such mechanism will be given. First, the characteristics of positioning by wire are described, then two necessary conditions for positioning by wire are given. On the basis of the two necessary conditions, the design conditions, including the number of necessary wires and the disposition condition of wires, are obtained from analysis of kinematics and dynamics of the mechanism. Further, a control algorithm adaptable to the mechanism with using optimal tension distribution is proposed.

This paper deals with one-axis toothed belt conveyor used as positioning mechanism in the system. A prototype of one-axis conveyor system has been developed to investigate positioning capability. To construct a flexible system which can easily change stroke, duration, velocity, and acceleration for different purposes, the conveyor is driven by a DC servo motor and controlled by a personal computer. Motion control using cam curves is applied to realize high accuracy and high speed conveying. Positioning accuracy, velocity characteristics, and residual vibration of the conveyor are also tested by experiments, and the results show that the developed conveyor system is effective as the positioning mechanism in the free-pallet index conveyor system.

    JOURNAL OF THE JAPAN SOCICTY FOR PRECISION ENGINEERING, The Japan Society for Precision Engineering, 59, 11, 1865-1870, 1993, A small SCARA robot for planar continuous path control has been developed. To realize high-speed and high-precision continuous path control, the robot was carefully designed by considering path planning, motion design, mechanism design, control system design, and teaching method design. The absolute accuracy performed by the robot is ±0.4mm in the standard working area(about A4 paper size), and the maximum speed of 500mm/s is obtained under reasonable accuracy. The accuracy is regarded as small as one tenth(1/10) of that performed by the conventional CP robots. The design policy is described and the experimental results are reported in this paper.

    明愛国; 古屋信幸; 牧野洋
    JOURNAL OF THE JAPAN SOCIETY FOR PRECISION ENGINEERING, The Japan Society for Precision Engineering, 54, 7, 1265-1271-1271, 1988, A new type robot called "Spherical SCARA (Spherical Selective Compliance Assembly Robot Arm) Robot" for the use of operations on a spherical plane has been developed. The robot has basically three joints (two rotational and one translational). It has the characteristic construction of "selective compliance", that means, the compliance in the normal direction to the working sphere is small, and which in the tangent plane and for momental force are large. With this construction the robot is adaptable to assembly operations, especially for insertion. In this report basic concepts on the robot are given, and several characteristics (coordinates transformation, singularity, compliance, positioning resolution, dynamics) are discussed.

    SASAI Ryota; SUZUKI Yosuke; MING Aiguo; SHIMOJO Makoto
    We propose haptic feedback methods based on proximity sensor output in teleoperation. Composed of four distance measurement sensors, the proximity sensors are mounted on the palm of the robot hand. When the palm of the robot hand faces an object, a plane of the object can be estimated. The operator Ls given a reaction force based on a model of virtual spring. The amplitude is determined by the distance to the estimated plane, and the direction is determined by the normal vector of the plane. In this paper, especially we propose three methods how the amplitude is determined by the distance, and we verify the differences of the operator perceiving the reaction force by each method., The Japan Society of Mechanical Engineers, 17 May 2015, ロボティクス・メカトロニクス講演会講演概要集, 2015, "1P2-N02(1)"-"1P2-N02(4)", Japanese, 110010055029, AA11902933

    In this paper, we propose a modular robot hand composed of RC servo motors which follows unknown shapes of objects using fingertip proximity sensors. The fingertip proximity sensor has been proved to enable the finger to keep constant distance and run parallel to an object by sensor feedback. The feedback control is simple and robust, and so it can be operated even using microcomputers and RC servo motors. High expandability is one of advantages of RC servo motors. By making the most of its characteristics, the robot hand can be changed degree-of- freedom (DOF) easily. The robot hand will be a variously deformable robot hand according to various purposes., The Japan Society of Mechanical Engineers, 17 May 2015, ロボティクス・メカトロニクス講演会講演概要集, 2015, "1P2-N08(1)"-"1P2-N08(4)", Japanese, 110010055035, AA11902933

    Generally, teleoperation of a robot hand with a monocular camera has problems of lack of depth information and the occlusion occur. The operator misrecognizes the position and posture of the object, and the robot hand cannot grasp the object. In the paper, to solve this problem, we use a proximity sensor, which we have developed, attached to the palm of the robot hand. The operator is able to recognize the position and posture of the object by using the proximity sensor. In addition, autonomy control based on the sensor enables to adjust the position and posture of the robot hand. We integrate operator control with autonomy control. The number of success of grasping the object increases and an operation burden decreases., The Japan Society of Mechanical Engineers, 17 May 2015, ロボティクス・メカトロニクス講演会講演概要集, 2015, "1P2-N07(1)"-"1P2-N07(4)", Japanese, 110010055034, AA11902933

" Both sensors are mounted on fingertips of our robot hand for object manipulation. The net-structure proximity sensor detects position and posture of an object, not only in non-contact but also in contact. The slip sensor detects pressure and slippage between an object in contact.

    This paper proposes a construction method for a Center of Pressure (CoP) tactile sensor using electrically-conductive paste and adhesion bond. The advantages are cost reduction and implement ability on various surface, because the conductive paste is able to draw electric circuits, for example, by pen-shaped tools, without using hot welding. A prototype sensor was implemented on a polypropylene sheet. It was confirmed that the sensor worked correctly and detected the position and amplitude of the applied force.

    TSUTSUI Yuhei; SUZUKI Yosuke; MING Aiguo; SHIMOJO Makoto
    In this paper, we propose a lattice modular robot which is able to perform both binding and transformation on 2D plane using helical magnets. A helical magnet has a cylindrical shape with helically-arranged magnetic poles on its surface. Modules have a square shape when viewed from the top. Helical magnets are arranged on each sides of square. Modules can bind each other by attraction of each of helical magnets. In addition, helical magnets work as a linear actuator by rotating it. This enables a module sliding transformation from its neighbor modules to further its adjacent modules. There are problems of existing modular robots that unable binding and unable transformation because of mechanical interference and lack of space. This proposed modular robot realizes various self-reconfigurations through overcoming those problems., The Japan Society of Mechanical Engineers, 17 May 2015, ロボティクス・メカトロニクス講演会講演概要集, 2015, "2A2-S10(1)"-"2A2-S10(4)", Japanese, 110010055646, AA11902933

    Electromagnetic motors are useful actuators for robots due to good controllability and low cost. But, usually electromagnetic motors together with reducers of high reduction ratio are used to actuate robots. It is difficult to realize creature-like dynamic motions such as fast running, high jumping, by the robots due to low backdrivability of joints. To solve the problem, a robot with leg mechanisms consisting of spring and damper inspired by bi-articular muscle-tendon complex of animals, has been developed. As the result of experiments for dynamic motion, trot running at a speed of 3.5 kilometers per hour and forward jump about 1 body length per jump have been realized by the robot., The Japan Society of Mechanical Engineers, 17 May 2015, ロボティクス・メカトロニクス講演会講演概要集, 2015, "2A2-P10(1)"-"2A2-P10(4)", Japanese, 110010055617, AA11902933

    Recently, the devices called "3D interface", which get gesture including Kinect and Leap Motion, attract people. Most of them use vision sensors for detecting human motion. However, we try to produce a new 3D interface without vision sensor, focusing on the net-structure proximity sensor our lab developed by.

    In this paper, we introduce an analog feedback system: constructed by several analog circuits and our proximity sensor, for generating a pre-shaping motion of a robot hand. The pre-shaping means adjustment of the fingertip-object distance and fingertip postures simultaneously. Through this motion, each fingertip surface contacts with object surface on target posture. So fingertip force can be applied to the object surface directly. Moreover, the pre-shaping advantages feedback control using tactile sensors after contact improving the reliability of the object grasping. By introducing the analog feedback system, it is possible to construct the system of the robot in a compact configuration as a whole., The Japan Society of Mechanical Engineers, 24 May 2014, ロボティクス・メカトロニクス講演会講演概要集, 2014, "3P2-S02(1)"-"3P2-S02(4)", Japanese, 110009967432, AA11902933

Among the joints of the two-legged robot, the variation of the torque necessary for the actuator is especially large in knee joint. In walking motion, two phases, swing phase and stance phase exist. In these two phases, the torque necessary for the knee joint actuators changes greatly. But reduction ratio of the actuators used for joints of the robot is generally constant. To solve the problem, we introduce a Load-Sensitive Continuously Variable Transmission in the knee joints, to adapt to the variation and then to achieve efficient walking motion., The Japan Society of Mechanical Engineers, 27 May 2012, ロボティクス・メカトロニクス講演会講演概要集, 2012, "2A2-V01(1)"-"2A2-V01(3)", Japanese, 110009909281, AA11902933

    Currently in many countries, the number of senior citizens who need help in daily life is increasing. We are developing a robotic system for assisting standing-up motions of the citizens from a chair by using a mobile manipulator. A standing-up posture estimation method has been proposed in our previous work, but the accuracy and processing time need to be improved.

    KOYAMA Keisuke; MUKOYAMA Yu; YE Sha; SUZUKI Yosuke; MING Aiguo; SHIMOJO Makoto
    In object grasping using vision sensors, occlusion occurs when a robot hand approaches around several millimeters from a grasping object. One solution of this problem is to introduce proximity sensors which detect the object position and distance in the near range area. Furthermore, when the weight of the grasping object is unidentified, slip sensors are required to grasp the object. This research focuses on pre-shaping using (net-structure) proximity sensors and integration of proximity sensors and slip sensors, in object passing and release tasks between a human and a robot hand. The posture of the object which the human holds out is detected by the proximity sensing, and the contact between the human and the grasping object is detected by the slip sensing., The Japan Society of Mechanical Engineers, 2012, The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), 2012, 0, _1P1-I03_1-_1P1-I03_4, Japanese, 110009908391

    In our research group, we are developing a signal processing system for a compact sized and high speed slip detective sensor.We found that it is difficult to tell initial slipping from shaped normal force charging with the traditional processing method by DWT(db2). But the raw signal of initial slipping is obviously different from the signal of a shaped normal force charging. So we differentiated the slip detection sensor's output to determine either the shaped normal force is charging or the tangential force is charging. As a result, we improved the accuracy of slip detection. I will report about that in this paper., The Japan Society of Mechanical Engineers, 2012, The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), 2012, 0, _1P1-A05_1-_1P1-A05_4, Japanese, 110009908319

    We have presented the availability of our slip sensor using pressure conductive rubber for detecting initial slip, however, we have not revealed the principle of high-frequency wave occurrence which takes the detection method. Clarification of the principle is required for optimized design of the slip sensor, especially the property of the pressure conductive rubber and the shape of the detecting part, and for reduction of individual difference of detection characteristic of the slip sensor. This paper discusses the principle through a series of experiments and finally shows that localized fixing and peeling between pressure conductive rubber and electrodes in the slip sensor configuration has influence with the principle., The Japan Society of Mechanical Engineers, 2012, The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), 2012, 0, _1A1-C02_1-_1A1-C02_4, Japanese, 110009907233

    In this paper, we propose a method for measuring distance independent of reflectance, shape and attitude by optical reflective sensors. This method uses two sensor layers: one layer has the sensor elements mounted in straight direction and the other has in tilt direction. The two sensor layer outputs have difference due to optical path length. By calculating the proportion of two sensor outputs, we can reject effect of reflectance, shape and attitude of object. We apply to multistage ring sensor for evaluate the availability of this method.

An analog circuit emulated this neuron network achieve the High-speed response. In this paper, we propose an edge detection method for an infrared proximity array with the lateral inhibition. In our approach, we first apply the photocurrent distribution obtained from that sensor to the lateral inhibition model. We then detect edge points from an edge enhancement: lateral inhibition output using zero-cross detection.

    The purpose of this paper is to consider the strategy of grasping a moving object robustly using the Net Structure Proximity Sensor which has fast response (1 ms) and detects the object position and distance in near field. In general, a temporary lack of sensory information due to occlusion occurs when using vision sensor to grasp object. In this strategy, we integrate the object following motion and the pre-shaping motion corresponding to the object posture together to grasp the object which moves randomly without any concern for occlusion using the proximity sensor. Specifically, the example of following the object from heights of 50mm makes it clear that it is possible to follow the object in maximum 30m/s in speculation., The Japan Society of Mechanical Engineers, 2012, The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), 2012, 0, _1A1-L01_1-_1A1-L01_4, Japanese, 110009907323

    In this paper, we propose the multi-point position measurement using a photo array and infrared LED which can be applied to three-dimensional user interface. In recent years, the digital terminal which manages and operates information is tended to multiply functions. Thus, the handleability of its interface decline relatively, and it is necessary to become skilled in operation. Accordingly, a touch panel which enables sensuous operation became widely used. These lead to the situation where user cannot make full use of function and the digital divide. Because an input and an output of a touch panel are seamless, the operation with the gesture input realizes a direct and intuitive interaction and improves the operability of digital terminal. An improvement in the handleability by an intuitive operation depended on the flexibility of the interface. Therefore, an improvement of the handleability is expected by expanding an input range from two-dimensions to three-dimensions., The Japan Society of Mechanical Engineers, 2012, The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), 2012, 0, _2P1-P02_1-_2P1-P02_2, Japanese, 110009909434

    The objective of this research is to detect posture of an object using the Net Structure Proximity Sensor applied to the fingertip of robot hand for reliable grasping. In object grasping and object sensing, occlusion occurs when using the vision sensor around several millimeters from grasping object. The solution of this problem is to introduce the proximity sensor which detects the object position and distance in near range area. The posture detection uses the sensor position output which takes zero not being affected by the distance whenever the surface of object and the surface of the sensor are parallel position. This detection technique is introduced to manage the object grasping successfully in adjusting the robot hand posture in two axes to appropriate grasping position., The Japan Society of Mechanical Engineers, 2011, The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), 2011, 0, _1A1-J02_1-_1A1-J02_4, Japanese, 110009690609

    Slip detecting tactile sensors are essential to achieving a human-like gripping motion with a robot hand.

This sensor can distinguish between condition of the object slip and the normal force change using a frequency component.

    Slip detecting tactile sensors are essential to achieving a human-like gripping motion with a robot hand. Up until now, we have proposed flexible, thin and lightweight slip sensor utilizing characteristics of pressure conductive rubber. When an object slides on the surface of our slip sensor, the complex output change occurs. By using this output change, this sensor can distinguish between the object slip and the normal force change. But, the mechanism of the complex voltage change is unclear.

    In this paper, we propose a design method of resistance for Net Structure Proximity Sensor (NSPS). Generally, vision sensors and tactile sensors are used for the external world measurement. A vision sensor has the problem of occlusion and a tactile sensor cannot detect until coming in contact. Therefore, we have developed NSPS that detects the intermediate area of vision and tactile area. NSPS can detect within 1ms the center position of the approaching object and the distance to the object without contact. This sensor is composed of resistor networks connected by phototransistor. The performance of NSPS is determined by the resistance in the networks. However, there was no practical design method of the resisters because of the network circuit. Accordingly, we describe a method for designing easily arbitrary dynamic range and faster measurement speed and confirm the validity of the proposed method., The Japan Society of Mechanical Engineers, 2011, The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), 2011, 0, _2P1-O01_1-_2P1-O01_4, Japanese, 110009711553

    In this paper, we considered an assessment function for effective optical elements placement of the Mesh of proximity sensor and searched a simulation result which maximizes the assessment function. Output characteristic of this sensor depends on relative placement of the optical elements. Since the placement has large amount of freedom, designing of the sensor which meets desired specification is difficult even using the optical simulator. Thus we proposed the simulator-supported method for effective element placement using Genetic Algorithm, and attempted to improve the sensor output characteristic over applying this method to the sensor design.

In previous studies, various walking measurement devices which is using pressure conductive element were developed, but they had several problems such as wires, responsivity, non-linearity and so on. So using we developed net structure tactile sensor, these problems were able to solve, but non-linearity problem that remains to be solved. And instead of pressure conductive rubber which have inferior repeatability, on/off switches which is quantitative and element use net structure sensor. Therefore the sensor charasteristics output is digitally and simplistically.

    To achieve a skillful operation like the human being by robot hand, an interaction with the vision and the tactile sense is indispensable. To consider the safe and certain grasping operation by the robot hand, we proposed use of proximity sensor which can detect the several tens of millimeters from finger-tip surface and tactile sensor. And we call such a robot hand an "intelligent robot hand" and develop this. This time, we propose the control method of internal force based on CoP(center of pressure) tactile sensor for the achievement of grasping by three fingers and confirmed utility of the proposal method by the experiments., The Japan Society of Mechanical Engineers, 25 May 2009, ロボティクス・メカトロニクス講演会講演概要集, 2009, "2A2-J04(1)"-"2A2-J04(4)", 110008698374, AA11902933

    The external world measurement sensor is useful so that the robot may evade the collision of man and the obstacle. However, a vision sensor has the problem of occlusion and a tactile sensor cannot be detected until coming in contact. Then, a proximity sensor that can detect the approach of the object is useful to interpolate the intermediate area of these vision and tactile area. We Study on the Proximity Sensor Network System that can be fitted on the free-form surface. In this paper, we simulated the sensor output by the ray-tracing method to examine the influence by having changed the arrangement of the light-emitting parts and light-receiving parts., The Japan Society of Mechanical Engineers, 25 May 2009, ロボティクス・メカトロニクス講演会講演概要集, 2009, "2A2-K06(1)"-"2A2-K06(4)", 110008698389, AA11902933

    Slip detecting tactile sensors are essential to achieving a human-like gripping motion with a robot hand. Up until now, we have proposed flexible, thin and lightweight slip sensor utilizing characteristics of pressure conductive rubber.

    This paper describes the morphing omnidirectional gripper which is able to grasp various objects with low melting point alloy. The deformable part of the gripper changes its shape by covering all directionof objects and makes the contacting area higher. In order to keep the high grasping force, proposed gripper does not need any additional energy thanks to the solid state of the deformable part including low melting point alloy. The design of the actual prototype model with cooling mechanism is shown and built. In addition, the usage of functional fluids for the morphing part is proposed.

    To achieve a human like grasping with a multi fingered robot hand, an interaction with vision and tactile information is indispensable. The method to use the camera for the vision information acquisition of the robot hand is common. The camera is effective globally but incorrect locally because of blind spot and the shadow of robot hand itself. Therefore it is thought that acquisition of approach and contact information to the object continually is very effective for grasping by introducing the proximity sensor which is sensing distance of several centimeter from an object.

    Takashi Shinohara; Yusuke Kobayashi; Aiguo Ming; Takashi Kida; Susumu Iizuka; Chisato Kanamori
    For Above Deck Equipment (ADE) on a ship, it is necessary to perform experimental modal analysis (EMA) by base excitation. Existing EMA tools are designed to perform curve-fitting on the frequency response function of displacement or acceleration at measuring point to an excitation force. However, in case of experiment by base excitation, transmissibility of acceleration, that is, the ratio of accelerations between measuring point and base is to be used for modal analysis. A method, which makes modal analysis for base excitation possible by performing curve-fitting on the transmissibility of acceleration using existing EMA tools, is proposed in this paper. First, the relation of transmissibility of acceleration using modal parameters in case of base excitation is derived. Based on the relation, a new method for modal analysis is given and its feasibility for one D.O.F. system is shown by numerical calculation. Finally, the method is applied to the modal analysis of an ADE, and its effectiveness is shown by comparing experimental results with simulation results using the modal parameters obtained by the method., Japan Society of Mechanical Engineers, 2005, Nihon Kikai Gakkai Ronbunshu, C Hen/Transactions of the Japan Society of Mechanical Engineers, Part C, 71, 12, 3388-3395, 0387-5024, 33644870089

    KAJITANI Makoto; KANAMORI Chisato; MING Aiguo; AOYAMA Hisayuki
    Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, The University of Electro-Communications, Grant-in-Aid for Scientific Research (B)., This project is a fundamental research on cooperation among multiple distributed autonomous mobile robots. The purpose is to develop cooperative control algorithms, sensor systems and several prototypes of mobile robot and mobile manipulator and to demonstrate the availability of developed systems by experiments. The basic concept of intelligent distributed autonomous robot system has been discussed and experiments by newly developed robots have been done by researchers at both University of Electro-Communications and Griffith University. The results obtained are as follows. 1) Several methods of obstacle detection and obstacle avoidance have been developed by using characteristics of multiple infrared sensor and ultrasonic sensor cooperatively. 2) As a case study, cooperation among multiple autonomous robots in intelligent vehicles and trans-portation systems is considered. Algorithm for road intersection crossing, front-vehicle tracking, overtaking, lane following, obstacle avoidance, front-vehicle distance control, narrow bridge crossing and formation driving have been developed and implemented to the robot system. 3) A new method, that is, rapid obstacle sensing using mobile robot sonar (ROSUM), for treating the crosstalk data of a so-called sonar ring, while employing a simultaneous firing regime has been proposed. It is shown by experiments that the robot with ROSUM sonar ring can avoide obstacles quickly and smoothly in complicated environment. 4) A new prototype of mobile manipulator with exchangeable active/passive joints has been developed in order to solve various problems in performing a cooperated task, in which a long pipe is to be moved out from a restrained location, transferred to an assigned position and set to a new restrained location. Experiments on proposed task by the cooperation of human and the mobile manipulator have been performed. The task was performed successfully by the simple control method. Cooperation for the task by two mobile manipulators will be done in the next work., 10044141

  • Development of a composite transmission characteristics measurement system for angle transmission mechanisms
    KAJITANI Makoto; KANAMORI Chisato; MING Aiguo
    Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, The University of Electro-Communications, Grant-in-Aid for Scientific Research (B), Angle transmission error, backlash and stiffness of an angle transmission mechanism exert a great influence on the servo performance in the mechatronic mechanisms. The purpose of this research is to investigate the relation between the characteristics of angle transmission mechanism and the control performance quantitatively. A composite transmission characteristics measurement system for angle transmission mechanisms has been developed and its capability has been evaluated by measurement experiments on typical angle transmission mechanisms. 1) Various angle transmission mechanisms, e.g. gear reducers, traction drive, timing belt can be measured by the developed system. Experimental conditions including inertial loads, torque load, input pattern of velocity, parameters of control system can be changed easily. Transmission error, backlash, stiffness and control performance (control errors of position and velocity, step response, stability) can be measured and evaluated on display or output to printer by this system. 2) This system can realize all functions of conventional angle transmission test system. Besides those functions, it can measure backlash continuously and measure dynamic transmission characteristics. The differences of transmission error due to the different polishing methods of teeth face can be observed also. 3) In the experiments of dynamic transmission on simple coupling mechanism with backlash and gear reducers, complicated vibration of transmission mechanism including contacting, collision (one side, two sides) and free states between driving and driven sides due to the existence of backlash was observed 4) A simulation model has been established for our system including dynamic model of mechanism and model of control system. Similar results can be obtained by simulation using this model. It will be useful for the controller design of a system with backlash., 09555054

    日本学術振興会, 科学研究費助成事業, 電気通信大学, 基盤研究(B), 1台のロボットでできない作業は複数のロボットで協調して行う必要がある.本研究は,2台の移動ロボットにより長尺パイプを設置された状態から取り外し,所定の経路を通って指定の場所まで搬送し,指定された位置に取り付けるという一連の具体的作業を設定し,その実現に必要なさまざまな問題を解決することを目的とし,以下の結果を得ている. (1) 2台の移動ロボットにより一連の作業(取り外し,搬送と取り付け)を行うシステムの概念設計を行った.まず一連の作業について解析を行い,2台の移動ロボットによる協調作業を前提としたマニピュレーション機能,移動機能を検討した.そして,各機能を実現でき,かつ簡単なシステムとして2輪独立駆動式の移動部と能動/受動切り替え可能な関節を有するマニピュレータからなる移動マニピュレータシステムを提案し,協調制御を考慮してマニピュレータの自由度の数と関節配置方法を決めた. (2) 5自由度の能動/受動切り替え可能な関節を有するマニピュレータと2輪独立駆動式の移動部からなる移動マニピュレータを設計し,試作した.能動/受動切り替え関節において,電磁クラッチを用いて切り替えを行い,受動時にも各関節の各位置を知るために関節軸にエンコーダも取り付けている. (3) 開発した1台の移動マニピュレータと人間の協調により,本研究で設定した一連の作業実験を行った.新たに開発した運動計画ソフトウエアにより移動マニピュレータの軌道を生成し,これらの作業を行う.受動関節により各作業中の位置誤差を吸収し,受動関節の変位に基づき移動マニピュレータの軌道修正を行う制御アルゴリズムを提案した.これらにより,人間との協調によりこの一連の作業を簡単な制御方法で成功させた. 今後,以上の成果に基づき2台の移動マニピュレータによる作業実験を行っていく予定である., 08455120
