Attempts have been made to reproduce the rotation and flexion of the wrist by adding degrees of freedom to the wrist joint. However, it is still difficult to fully reproduce the functionality of the wrist joint owing to the weight of the prosthesis and size limitations. In this study, we developed a new socket and prosthetic hand control system that does not interfere with the wrist joint motion. This allows individuals with hand defects who previously used prosthetic hands with fixed wrist joints to freely use their remaining wrist functionality. In the pick-and-place experiment, where blocks were moved from higher to lower locations, we confirmed that the proposed system resulted in a lower elbow position compared with the traditional prosthesis, and the number of blocks transported increased. This significantly reduced the compensatory motion of the elbow and improved the user’s performance compared with the use of a conventional prosthetic hand. This study demonstrates the usefulness of a new myoelectric prosthetic hand that utilizes the residual functions of people with hand deficiencies, which have not been utilized in the past, and the direction of its development.

Scientific journal - A Hand Gesture Recognition Strategy Based on Virtual-Dimension Increase of EMG
Yuxuan Wang; Ye Tian; Jinying Zhu; Haotian She; Yinlai Jiang; Zhihong Jiang; Hiroshi Yokoi
Cyborg and Bionic Systems, American Association for the Advancement of Science (AAAS), 5, 29 Jan. 2024, The electromyography(EMG) signal is the biocurrent associated with muscle contraction and can be used as the input signal to a myoelectric intelligent bionic hand to control different gestures of the hand. Increasing the number of myoelectric-signal channels can yield richer information of motion intention and improve the accuracy of gesture recognition. However, as the number of acquisition channels increases, its effect on the improvement of the accuracy of gesture recognition gradually diminishes, resulting in the improvement of the control effect reaching a plateau. To address these problems, this paper presents a proposed method to improve gesture recognition accuracy by virtually increasing the number of EMG signal channels. This method is able to improve the recognition accuracy of various gestures by virtually increasing the number of EMG signal channels and enriching the motion intention information extracted from data collected from a certain number of physical channels, ultimately providing a solution to the issue of the recognition accuracy plateau caused by saturation of information from physical recordings. Meanwhile, based on the idea of the filtered feature selection method, a quantitative measure of sample sets (separability of feature vectors [SFV]) derived from the divergence and correlation of the extracted features is introduced. The SFV value can predict the classification effect before performing the classification, and the effectiveness of the virtual-dimension increase strategy is verified from the perspective of feature set differentiability change. Compared to the statistical motion intention recognition success rate, SFV is a more representative and faster measure of classification effectiveness and is also suitable for small sample sets.

Frontiers in Neuroscience, Frontiers Media SA, 17, 30 Nov. 2023, Faced with the increasingly severe global aging population with fewer children, the research, development, and application of elderly-care robots are expected to provide some technical means to solve the problems of elderly care, disability and semi-disability nursing, and rehabilitation. Elderly-care robots involve biomechanics, computer science, automatic control, ethics, and other fields of knowledge, which is one of the most challenging and most concerned research fields of robotics. Unlike other robots, elderly-care robots work for the frail elderly. There is information exchange and energy exchange between people and robots, and the safe human-robot interaction methods are the research core and key technology. The states of the art of elderly-care robots and their various nursing modes and safe interaction methods are introduced and discussed in this paper. To conclude, considering the disparity between current elderly care robots and their anticipated objectives, we offer a comprehensive overview of the critical technologies and research trends that impact and enhance the feasibility and acceptance of elderly care robots. These areas encompass the collaborative assistance of diverse assistive robots, the establishment of a novel smart home care model for elderly individuals using sensor networks, the optimization of robot design for improved flexibility, and the enhancement of robot acceptability.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference, 2023, 1-4, Jul. 2023, True, Function electrical stimulation (FES) is recommended as one of the effective methods for rehabilitation of motor function after stroke. There are two forms to deliver electrical stimulation to induce muscle contraction: Bipolar electrode configuration with two electrodes of the same size, and monopolar electrode configuration with a bigger electrode as an indifferent electrode and a smaller one as an active electrode. The purpose of this study is to compare the two kinds of configuration on biceps brachii in terms of induced muscle contraction force and muscle fatigue. In the experiment, electrical stimulation was applied on biceps brachii muscles of the right arm. Isometric contraction was induced by fixing the elbow joint during the stimulation. The experimental results showed that the induced contraction force was bigger using monopolar electrode configuration with the indifferent electrode on the antagonist muscle, and there was no significant difference in muscle fatigue between the configurations. Monopolar electrode configuration with the indifferent electrode on the antagonist muscle was suggested as the most effective method for FES on biceps brachii.Clinical Relevance- This study establishes an effective electrode configuration for FES on biceps brachii.

Last, Cyborg and Bionic Systems, American Association for the Advancement of Science (AAAS), 2022, Article ID: 9861875, 16 Jan. 2022, Peer-reviwed, The usability of a prosthetic hand differs significantly from that of a real hand. Moreover, the complexity of manipulation increases as the number of degrees of freedom to be controlled increases, making manipulation with biological signals extremely difficult. To overcome this problem, users need to select a grasping posture that is adaptive to the object and a stable grasping method that prevents the object from falling. In previous studies, these have been left to the operating skills of the user, which is extremely difficult to achieve. In this study, we demonstrate how stable and adaptive grasping can be achieved according to the object regardless of the user’s operation technique. The required grasping technique is achieved by determining the correlation between the motor output and each sensor through the interaction between the prosthetic hand and the surrounding stimuli, such as myoelectricity, sense of touch, and grasping objects. The agents of the 16-DOF robot hand were trained with the myoelectric signals of six participants, including one child with a congenital forearm deficiency. Consequently, each agent could open and close the hand in response to the myoelectric stimuli and could accomplish the object pickup task. For the tasks, the agents successfully identified grasping patterns suitable for practical and stable positioning of the objects. In addition, the agents were able to pick up the object in a similar posture regardless of the participant, suggesting that the hand was optimized by evolutionary computation to a posture that prevents the object from being dropped.

Sensors, MDPI AG, 21, 18, 6234-6234, 17 Sep. 2021, Peer-reviwed, Myoelectric prosthesis has become an important aid to disabled people. Although it can help people to recover to a nearly normal life, whether they can adapt to severe working conditions is a subject that is yet to be studied. Generally speaking, the working environment is dominated by vibration. This paper takes the gripping action as its research object, and focuses on the identification of grasping intentions under different vibration frequencies in different working conditions. In this way, the possibility of the disabled people who wear myoelectric prosthesis to work in various vibration environment is studied. In this paper, an experimental test platform capable of simulating 0–50 Hz vibration was established, and the Surface Electromyography (sEMG) signals of the human arm in the open and grasping states were obtained through the MP160 physiological record analysis system. Considering the reliability of human intention recognition and the rapidity of algorithm processing, six different time-domain features and the Linear Discriminant Analysis (LDA) classifier were selected as the sEMG signal feature extraction and recognition algorithms in this paper. When two kinds of features, Zero Crossing (ZC) and Root Mean Square (RMS), were used as input, the accuracy of LDA algorithm can reach 96.9%. When three features, RMS, Minimum Value (MIN), and Variance (VAR), were used as inputs, the accuracy of the LDA algorithm can reach 98.0%. When the six features were used as inputs, the accuracy of the LDA algorithm reached 98.4%. In the analysis of different vibration frequencies, it was found that when the vibration frequency reached 20 Hz, the average accuracy of the LDA algorithm in recognizing actions was low, while at 0 Hz, 40 Hz and 50 Hz, the average accuracy was relatively high. This is of great significance in guiding disabled people to work in a vibration environment in the future.

Methods: An epilepsy patient with implanted intracranial electrodes participated in this study. IEEGs were recorded while the patient imitated simulated movement of a robot arm. Independent component analysis (ICA) and partial least squares regression (PLS) were used to extract components specifically distributed over the sensorimotor areas. These components were used to estimate the wrist velocity vector using support vector regression (SVR). The robot arm was three-dimensionally controlled based on the estimated velocity using ROS where inverse kinematics were implemented.
Results: We developed the system for real-time three-dimensional control of a robot arm by estimating the wrist velocity based on iEEG using ICA, PLS and SVR.
Conclusion: Three-dimensional velocity control based on iEEG, ICA, PLS and SVR is feasible for real-time control of a robot arm.

The developed system consisted of four degrees of freedom joints and control system adapting a user through machine learning technique and surface myoelectric potential of the trunk. We measured the surface myoelectric potential of the trunk of healthy subjects at multiple points and analyzed by using a principal component analysis to identify the proper myoelectric potential measurement part of the trunk. As a result, it was revealed that the proper EMG measurement site of the trunk is distributed in the chest and back. In addition, as a result of the experiment of verifying the grasping / moving motion of the object by the shoulder artificial arm using the surface myoelectric potential of the chest and the back for controlling the motion of the arm, all the subjects successfully grasped and moved the object within a certain period of time.

情報管理, Japan Science and Technology Agency, 58(2015), 12, 887-899, 01 Mar. 2016, Invited, This paper describes a prosthetic hand for both complementing the function of the hand and for enhancing the function of the body. Types, structures and the operational principles of traditional prosthetic hands are explained, and then the details of prosthetic hands that are controlled by the users electromyogram (EMG), which is the principal subject of this paper, are also explained. The EMG prosthetic hand was first developed over half a century ago; however, there have been no major changes in the control strategy of EMG prosthetic hands in their long history. Although the traditional EMG control strategy is optimized for EMG prosthetic hands with single degrees of freedom, these days EMG prosthetic hands with multiple degrees of freedom are becoming available on the market, and as a result, many people have difficulties with controlling them. Our research group has developed a novel intuitive EMG controller for prosthetic hands with multiple degrees of freedom, and the developed EMG controller outlines the possibility for physical expansion. Finally, we outline the change in society based on this technology, and its possible future expansion.

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), The Japan Society of Mechanical Engineers, 2016, 1P1-14a4, 2016, Electromyogram (EMG) signals represent the electric potentials on the surfaces of muscles. These signals may be applied for controlling prosthetic replacements such as a prosthetic hand. This paper treats on application of EMG prosthetic hand for congenital defects. The experimental product of EMG prosthetic hand is developed for the subjects under 5 years old. The main problem of experimental product is a design issue of socket of amputee. The socket needs to support all weight of prosthetic hand and object of handling. Furthermore, EMG sensor electrodes are needed to be attached on the surface of amputee side firmly, in order to avoid noise. Therefore this paper proposes new socket design by using conductive polymer and flexible fabric. The experimental result shows that the prototype socket is applied for infant amputees and succeeded to grasping and releasing small object and holding big heavy object by using EMG prosthetic hand.

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), The Japan Society of Mechanical Engineers, 2016, 2A1-14a3, 2016, In this paper presents the result of developed robot hand for grasping and manipulating objects as prosthesis by using 3D printing. Author's group develops myoelectric hand for infants which are amputee with transverse deficiencies. A robot hand is required ultra-small, ultra-light, grasping force similar with infant's grasping force and less discomfort movement of hand. As the result, we have developed ultra-light robot hand which is same grip force and pinch force comparing with conventional hands. Specifications of the robot hand shows; size is similar with 2 years old child, weight is 50g ( with no cosmetic globe), 70g( with cosmetic globe), grasp force is about 18.6N. Finally, we have verified usefulness of robot hand for myoelectric hand for infant, by conducting the experiments about mechanical performance and subject experiment.

Therapeutic Research, 37, 8, 795-802, 2016, Peer-reviwed, Humans can identify partly occluded objects such as fragmented letters and the process involved could be considered as a common ability to discriminate, for example, between animal camouflage and jungle surroundings. The present study found that the same mechanism is responsible for visual identifying fragmented letters. Psychological experiments showed that individuals with normal vision most frequently imagined the shortest-linear links when observing three points corresponding to the vertices of virtualscalene triangles. Computer simulation also showed that multiple lines between pixels in close proximity remaining within the fragments with randomly removed pixels reproduced the shapes of original letters. Therefore, these results suggest that fragmented letters can be identified via linkages of spontaneously-induced illusory lines that interpolate elements remaining in close proximity within the visual system of the brain.

Proceedings of the Fuzzy System Symposium, Japan Society for Fuzzy Theory and Intelligent Informatics, 30, 694-697, 2014, Use of a myoelectric prosthetic hand is an effective way to rehabilitate upper limb motor function of amputee. In our previous study, we have already developed a two DoF prosthetic hand which has driving MP (meta phalangeal) joint of interlocked middle finger and index finger, and CM (carpometacarpal) joint of thumb. It is structured to perform three grasping postures, namely, power grip, precision grip and lateral pinch. To realize holding function with these postures, 85% of hand movement for ADL is covered. Though the grip performance of the hand depends on joint angles of thumb and fingers, the shape of hand was decided on an empirically. Therefore, the problem that we cannot design the shape of hand according to desired function was remained. It should be solved to clarify the relationship between hand functions and shape with a proper shape model. In this study, we proposed a shape model for function design of the two-DoF prosthetic hand, and confirmed the hand function by some experiments. Then, we measured their gripping force by pull-out test, and evaluated the hand function in daily life by Pick-and-Place task with selected target which are frequently used in daily life. The result shows following tendency: (1) the bending angles of fingers and thumb are larger, their pull-out force are larger, and their grasping function- are lower, (2) the bending angles of fingers and thumb are smaller, their pull-out force are smaller, and their grasping functions are higher.

日本ロボット学会誌, The Robotics Society of Japan, 28, 7, 783-791, Sep. 2010, Peer-reviwed, The purpose of this research is to discriminate many motions using EMG signal for prosthetic application's control. The basic idea of this study is that, the current degree of proficiency, i.e., how well the application is operated by a user is to be analyzed from bio-signal closely related to human motor process, and control rule is generated depending on the proficiency level. Thus, our proposed system consists of two parts: estimation of user's proficiency level using EMG signal, and motion classification using self-organized clustering. In the experiment, users trained to discriminate motions using our proposed system, and then they all were able to discriminate seven forearm motions with approximately 90% accuracy. In addition, one of the users was able to discriminate nine motions with 21% higher accuracy than before training. The results indicated the effectiveness of proposed system.

In this paper, we evaluate amputee's motor recovery by using adaptable myoelectric hand from the standpoint of brain function and clinical practice. As a result, we clarified that robust control ability of prosthetic hand activates the activity of the primary motor cortex, and the substitute function of the body provided by the myoelectric hand realizes the motor recovery as close to healthy person's body function.

JRSJ, The Robotics Society of Japan, 27, 7, 732-738, 15 Sep. 2009, Peer-reviwed, A low-invasive method to record neural activity is required for safe and practical brain-machine interfaces (BMI). BMIs are expected to be used to reintegrate motor functions of physically disabled persons; however, conventional invasive methods require electrodes inside the dura mater. In this study, the authors used epidural electrodes, which are located between the skull and dura mater, to record rat neural activity for low-invasive BMI. The signals were analyzed using short-time Fourier transform, and the power spectra were classified into rat behavioral conditions by an artificial neural network and a support vector machine. The accuracy was approximately 60∼85% in two behavioral conditions classifications according to the tested electrodes' locations and frequency bands. The results indicated the feasibility of low-invasive BMI using epidural electrodes.

In order to identify the brain system, the multi-site and simultaneous recording is required. However, the property of the invasiveness leads to miniaturizing such a device. Therefore, the multi-site microprobe was fabricated by applying a multilayer structure of electrical circuits. Moreover, the anisotropic etching was applied in order to simplify the fabrication process. And the electrical property of this microprobe was described.

日本ロボット学会誌, The Robotics Society of Japan, 19, 2, 85-95, Mar. 2001, Peer-reviwed, This paper describes a design method of a robot system which consists on mechanically linked plural agents, so as to realize autonomous robots which can adaptively behave in the real world. A difficulty in designing distributed autonomous systems, is how to embed a dynamics for self organizing environment-oriented-action-rules in the systems. So, we propose a robot system which controlled by a decision making method that has oscillator and learning method based on same object functions, and which has a structure of mechanically linked agents that are identically designed, in order that each agent actively interacts with other agents and the outer world. For verifying an usefulness of the system, behavioral acquiring tests in target approaching and obstacle avoidance were implemented by using Distributed Autonomous Swimming Robot that was constructed by the proposed way. Moreover, for learning efficiency in complex tasks such as obstacle avoidance, we proposed Switching Q-learning in which previously obtained action rules were effectively used As a result, the robot acquired simple obstacle avoidance behavior, and time-sequential connections between acquired action rules were observed by interaction-based learning in a distributed autonomous system. That is, it was verified that the proposed system design method was one of the solutions of adaptive systems to complex environments.

人工知能学会誌, 人工知能学会, 15, 5, 896-903, Sep. 2000, Peer-reviwed, In Multi-Agent Systems, agents sense their local information, and they estimate the global environment. Autonomous agents should have independent estimate functions according to their local information. The functions should adapt the global environment. We consider this estimate function to be exactly a "norms of behavior" in the human sense. In this study, we construct a competitive social system with selfish autonomous agents. Agents interact with their alternative actions each other repeatedly as like as IPD(Iterated Prisoner's Dilemma)games.Agents have a estimation table for their action independently. Agents'strategies of action are adapted to their own estimate function, and agents'norms of behavior satisfy. But global environment deprives their energy according to a global rule. In such systems, the agent which adapt not only strategy but also norms of behavior to the environment can survive.

電子情報通信学会論文誌D-II, The Institute of Electronics, Information and Communication Engineers, J82-D-II, 9, 1510-1519, Sep. 1999, Peer-reviwed, 本論文では筋電義手制御のための新しい学習法を提案する.従来研究されている筋電義手の制御手法は,切断者に対する義手適用訓練と義手に対する個人差の学習を別々に行うOff-line型である.そのため切断者は訓練中においては義手操作の感覚をつかみづらく,使用中は義手を自身の変化に追従させるのが困難であった.そこで本論文では実時間で学習を行うOn-line型の学習機構を設計する.本手法では切断者本人が使用中に与える評価から,義手装置は表面筋電位と動作の間の適切な写像関係を獲得する.これにより訓練時間の短縮と個人差への適応を実時間で実現する.本論文では手法の検証のために6種類の動作識別実験を行っている.まず前腕の運動イメージを用いた実験を行い,従来のOff-line型の手法と比較している.更に上腕での切断者を意識して,肩甲帯の運動から筋電信号を取り出し義手駆動実験を行っている.実験における前腕での識別率は提案手法で89.9%,従来法で80.3%であった.また提案手法における肩甲帯での識別率は79.3%の性能が達成されており,上腕切断者に対する本筋電義手制御法の適用の可能性が確かめられている.

Because the surface EMG vary from individual person to person, it is very difficult to control this kind of prosthesis (almost one month of training is needed). To overcome this problem, we develop such prosthesis whose controller can be adapt to the characteristics of an individual person's surface EMG.In this adaptation, the Evolvable Hardware(EHW)is used for the controller of the prosthesis.

日本機械学会論文集C編, The Japan Society of Mechanical Engineers, 60, 580, 124-129, Dec. 1994, Peer-reviwed, A new approach of finding the path to a goal automatically is proposed in this paper. For this problem, our approach uses the vibrating potential method (VPM) to provide the strategy for finding the path. The VPM is a new problem solving system we proposing, and has sufficient unity of fundamental mathematical expression to describe the movement of agents as autonomous machines. In this method, a vibrating potential field (VPF) as an environment is constructed by agents and their interaction energy. These agents interact with each other by the information from the detected wave motion from the environmental surroundings. By the VPM, each agent can decide its movement through detection of wave motion as the environmental surroundings without specific problem oriented programming. In this paper, we set moving-robot agents (RA), obstacle agents (OA) and goal agent (GA) on VPF. We show computer simulations that RA can find the path by two methods. One is position control by local-area sensoring and the other is path planning by detecting global information from GA.

日本機械学会，日本機械学会論文誌Ｃ編, The Japan Society of Mechanical Engineers, 59, 564, 2346-2352, Aug. 1993, Peer-reviwed, In this paper, we aim to solve the obstacle-avoidance problem using the vibrating potential method (VPM). The obstacle-avoidance problem is famous inthe field of a navigation of automatically guided vehicles (AGV). There are many kinds of behavior for a group of AGVs such as forward and backward movement, rotation, fission, fusion, avoidance of obstacles and passing through free-form narrow paths. Since these types of behavior are capable of changing according to the environmental surroundings of the AGVs or their goals, the problem can be described using three systems : "Obstacles," "AGVs" and "Goals". For this problem, we use the VPM to obtain a strategy for achieving a goal for each AGV. In the VPM, an environment is constructed by means of a wave motion propagated from the obstacles, AGVs and goals. These subsystems of the obstacle-avoidance problem system interact with each other through the information from the detected wave motion from the environmental surroundings. Using a VPM, each AGV can decide upon its movement through detection of wave motion from the environment surroundings without specific problem-oriented programming. Furthermore, the movement of a group of AGVs is represented in computer simulations for such situation as approaching behavior for each goal, avoiding obstacles and fission and fusion behavior.

Humanoid robotic upper limbs including the robotic hand and robotic arm are widely studied as the important parts of a humanoid robot. A robotic upper limb with light weight and high output can perform more tasks. The drive system is one of the main factors affecting the weight and output of the robotic upper limb, and therefore, the main purpose of this study is to compare and analyze the effects of the different drive methods on the overall structure. In this paper, we first introduce the advantages and disadvantages of the main drive methods such as tendon, gear, link, fluid (hydraulic and pneumatic), belt, chain, and screw drives. The design of the drive system is an essential factor to allow the humanoid robotic upper limb to exhibit the structural features and functions of the human upper limb. Therefore, the specific applications of each drive method on the humanoid robotic limbs are illustrated and briefly analyzed. Meanwhile, we compared the differences in the weight and payload (or grasping force) of the robotic hands and robotic arms with different drive methods. The results showed that the tendon drive system is easier to achieve light weight due to its simple structure, while the gear drive system can achieve a larger torque ratio, which results in a larger output torque. Further, the weight of the actuator accounts for a larger proportion of the total weight, and a reasonable external placement of the actuator is also beneficial to achieve light weight., American Association for the Advancement of Science (AAAS), 2021, Cyborg and Bionic Systems, 2021, 9817487, 1-12, English, Peer-reviwed, Introduction scientific journal, 2692-7632 - 個性適応システムを有するユニバーサルソケットの有用性評価

A stationary grasping posture is classified in the control method of an electromyogram prosthetic hand. This grasping posture is static, such as an open hand posture, and one in which the operator of an electromyogram prosthetic hand intentionally continues muscular contraction. In operating prosthetic hand, because an operation image of prosthetic hand is different from the image of normal hand, an operator feels unnaturally. In this paper, authors propose a method that predicts a grasping posture using the surface electromyogram in hand preshaping and physical quantity sensors to solve the problem. Experimental results demonstrate that operators be able to control the prosthetic hand using proposal method more naturally than using conventional method., The Japan Society of Mechanical Engineers, 20 Mar. 2015, 日本機械学会関東支部総会講演会講演論文集, 2015, 21, "10413-1"-"10413-2", Japanese, 110009948194, AA11902161 - 慢性期脳梗塞症例に対する1か月間の機能的電気刺激療法を用いたホームエクササイズは脳活動に影響を与えるか:―PET画像を用いた検討―

【はじめに，目的】機能的電気刺激（functional electrical stimulation：FES）は，運動機能を改善する目的で脳卒中や脊髄損傷後の症例で用いられており，実際に歩行などの運動機能が改善した報告が散見される。近年では，電気刺激に伴い体性感覚皮質や島の賦活が報告されるなど，FESが脳活動に与える影響に注目されている。しかし，実際にFESの治療中及び治療期間前後の脳機能画像を評価した報告は我々が捗猟し得た限りない。ポジトロン断層法（positron emission tomography：PET）は，放射性トレーサーを用いて脳血流量を間接的に測定することで，脳活動の変化を客観的に把握することができる。電気刺激がPET撮像に影響を与えることはなく，fMRIほど動きが制約されないことから，FESの脳機能評価としてPETは有用である。そこで本研究では，慢性期脳梗塞症例に対して1か月間のFESを用いたhome exerciseを実施し，その前後の運動課題中の脳活動をPETを用いて評価し，若干の知見を得たので報告する。【方法】症例は発症3年以上経過した慢性期脳梗塞症例5名である（平均発症期間7.6±3.7年，男性3名，女性2名，平均年齢61.8±20.1歳）。本研究はcross-over designとし，FESを用いたhome exercise 1か月間とFESを用いないhome exerciseを1か月実施する期間を作成し，その順序はランダムに規定した。home exercise開始前及び各時期終了後にPET撮像と身体機能評価を実施した。脳機能画像評価はH<sub>2</sub>[<sup>15</sup>O]-PETにて測定し，頭部の過剰な動きを抑制するために頸椎カラーを装着した。PET撮像は，①安静，②随意運動のみ，③電気刺激のみ，④随意運動と電気刺激の併用の4タスクとし，3分間のタスク中の脳血流を測定した。電気刺激は麻痺側大腿四頭筋に実施し，電極は内側広筋と外側広筋のモーターポイントに貼り付けた。電気刺激はCarrier周波数2000Hz，Burst周波数を100Hz，Duty比50%の双極矩形波とし，疼痛は感じないが十分筋収縮が生じる強度とした。運動タスクは下肢伸展運動とし，最大等速性筋力の10％の負荷量を抵抗とした。下肢伸展運動は4秒間伸展―4秒間屈曲のリズムとし，伸展相に電気刺激が同期するよう設定した。各時期前後には身体機能評価として，Hand held dynamometerを用いた等尺性筋力，バランス機能評価であるBerg balance scale（BBS），歩行機能評価を実施した。1ヶ月間のhome exerciseは座位での膝伸展運動とし（20分間2セット/日，5回/週），FESを用いた時期には運動に合わせて電気刺激を負荷させるようにした。【結果】Home exercise開始前の脳機能画像評価では，随意運動のみでは対側運動野を中心に血流増大が認められ，電気刺激のみでは血流増大は認めず，電気刺激と随意運動の併用では対側感覚野に血流増大領域が拡大していた。比較的麻痺重症例では，随意運動のみでは両側の運動関連領域の血流が増大していたが，電気刺激と随意運動の併用により同側脳血流は減少し，対側運動関連領域に賦活は限局化していた。1か月間のFES併用のhome exercise後のPETでは，介入前と同様な運動タスクであるにも関わらず，随意運動のみで血流増大領域の限局化がみられた。一方，FES非実施home exercise前後ではこの限局化の反応は明確ではなかった。大腿四頭筋等尺性筋力やBBSでは，FES実施home exercise期間でもFES非実施home exercise期間でも増加する傾向を認めたが，各期間で明らかな違いは認められなかった。【考察】随意運動のみと比較して電気刺激を併用することにより即時的に感覚野まで賦活範囲が拡大しており，電気刺激を併用することで感覚入力が増大していることが考えられた。1か月間FESを用いたhome exerciseを実施することで，FESを実施しない時期と比較して明らかな身体機能の変化は見られなかったが，PET画像では随意運動のみで賦活する範囲が限局化していた。これは，限局化した脳活動で同一のタスクが行えるよう変化していることを示唆しているのではないかと推測された。【理学療法学研究としての意義】脳卒中ガイドラインでFESは推奨されているものの，実際の臨床で広く使用されているとは言い難い。その理由としてFESがもたらす効果が十分解明されていないことが考えられる。本研究では，慢性期脳梗塞症例においてもFESを用いたhome exerciseによって短期的に脳賦活パターンに変化が生じたことが示され，理学療法研究として意義が大きいと考えられる。, 公益社団法人 日本理学療法士協会, 2015, 理学療法学Supplement, 2014, 0, Japanese, 130005248222 - Brain machine interfaces using electrocorticograms: development towards clinical application

Brain machine interfaces (BMIs) using intracranial electroencephalograms (electrocorticograms) are a promising candidate of the clinical application of high performance BMIs. We demonstrated that high frequency band activity is an excellent feature to decode movement onset and type, independent of the severity of motor dysfunction. Using the decoding features, real time control of a robotic arm was successfully performed by the patients that brain surface electrodes were placed to treat intractable epilepsy or intractable pain. We started a clinical trial in severe ALS patients using a wired BMI system involving the temporary placement of newly-developed personalized electrodes. A fully implantable wireless system is indispensable for clinical application of invasive BMIs to reduce infection risk. We are now developing the implantable system, which includes a 128-ch integrated amplifier circuit, 3D personalized high density electrodes, a wireless data transfer system and a wireless battery charger. We aim to put the implantable system to clinical use as soon as possible., Japanese Society for Medical and Biological Engineering, 2015, Transactions of Japanese Society for Medical and Biological Engineering, 53, 0, S145_02-S145_02, Japanese, 130005163770 - K15100 Functional Recovery induced by Phantom Sensation using Mutual Adaptable Biofeedback : Adaptable EMG Prosthetic Hand and Electric Stimulator
Yokoi Hiroshi
This work reports on a biomedical robotic approach for neuroprosthesis based on body image adjustment. A novel concept of functional recovery of motion based on biofeedback to connect the intentions of motion and the sensory input has attracted considerable attention. This study describes adaptable EMG prosthetic hand experiments that show that the sensory motor cortex indicates the human intentions of motion through synchronized proprioceptive sensor inputs. This illusion induces strange activities in the sensory motor area according to the synchronous biofeedback of interference-driven electrical stimulation. The proposed device can be applied for the rehabilitation of paralysis due to stroke; it has functions for changing the stimulation parameters and controlling many channels in order to adapt to various types of paralysis and to support complex movements such as grasping, standing, and walking., The Japan Society of Mechanical Engineers, 07 Sep. 2014, Mechanical Engineering Congress, Japan, 2014, "K15100-1"-"K15100-5", Japanese, 110009944169, AA12588255 - リアルタイム脳磁計による神経義手を用いた求心路遮断性疼痛の病態解明

Myoelectric hand is required that enabling user to achieve various kinds of Activities of Daily Living (ADL). Above all, grasping behavior which accounts for 85 percent of ADL is necessary to achieve first. In grasping behavior, human controls the five fingers dexterously. In the five fingers' movements, the most important movements are opposition-apposition and adduction-abduction of thumb for grasping behavior. Therefore it is necessary that myoelectric hand has the two movements of thumb. Actually, there are some myoelectric hands which are being marketed. But these are so heavy that wearing those hands are a burden to users. To solve that problem, myoelectric hands used tendon driven which enable to make hands light have been being developed now. But, previous thumb mechanism is short for range of motion and torque. So it does not achieve enough kinds of grasping behavior. In this study, we developed a coupled-tendon driven thumb mechanism which can do opposition-apposition and adduction-abduction. This mechanism does opposition-apposition by using cylindrical guide set on opposition axis to enable to balance two wires. And this one dose adduction-abduction and flexion-extension by towing three links set on the link which moves around opposition axis perpendicularly from palp of hand. A prototype confirmed that proposal mechanism is enough to light to use as myoelectric hand and has range of motion the same as human. Moreover, prototype confirmed that it has more torque of adduction up to 670% than previous mechanism and achieves grasping behavior used in daily living., The Japan Society of Mechanical Engineers, 08 Sep. 2013, Mechanical Engineering Congress, Japan, 2013, "J151034-1"-"J151034-4", Japanese, 110009935444, AA12588255 - J151024 Decision technique of the most suitable placement of the stimulation electrode for limbs control using surface electrical stimulation : Design of a pulse select circuit selecting the most suitable electrodes from many electrodes
SATO Yuki; SUZUKI Minako; KATO Ryu; YOKOI Hiroshi
Precise motor point stimulation is needed for efficient functional electrical stimulation (FES) because the stimulation of the motor point makes the muscle to contract the most. However physical therapists have difficulties of determining the position of motor point, because the position of motor point is different about 20% of muscle length among individuals. Therefore the purpose of this paper is to develop the automated FES electrodes positioning system which can stimulate the motor point precisely. This research deals with this purpose by developing the pulse select circuit, which can allocate FES stimuli to the multiple arbitrary electrodes. Therefore this circuit can search the most efficient pattern of electrodes positions by selecting stimulating electrodes in various patterns. Thus developed circuit can change position and area of stimulation at once: a wide variety of muscles are applicable. Moreover, developed circuit can be applied to other bio-instrumentation system which searches the best stimulation position. The developed pulse select circuit consists of a microcomputer, demultiplexers and photo-MOS relays, and it can select one arbitrary FES output line out of four output lines, and assign the selected output line to multiple arbitrary electrodes., The Japan Society of Mechanical Engineers, 08 Sep. 2013, Mechanical Engineering Congress, Japan, 2013, "J151024-1"-"J151024-5", Japanese, 110009935438, AA12588255 - 学習型筋電ハンドの製作

MORISHITA Soichiro; YOKOI Hiroshi
Authors have discussed foreseeability of experts about the malfunction of an automatic machine caused by the event which is out of the coverage of the machine. The expert can make a proper decision based on expertise about the coverage of the automatic machine. On the other hand, non-experts become anxious about the handling of the automatic machine and may underestimate the machine's coverage. When the malfunction that experts cannot foresee occurs under such a situation, the result accords with the forecast by non-experts by chance. Then, the experts are held excessively responsible for the foreseeability. In this paper, we proposed a model which explain this cognitive bias of non-experts. The concept of "unknowable variable" is introduced to the state variables, which express the state of automatic machines. Then we explain that the tentative values are determined by the subjectivity of the person evaluating automatic machines. Moreover, based on the model, we qualitatively show that non-experts are apt to underestimate the coverage of the automatic with a case study approach., The Institute of Electronics, Information and Communication Engineers, 12 May 2011, IEICE technical report, 111, 41, 1-4, Japanese, 0913-5685, 110008725540, AA11651731 - 急性期脳卒中患者における歩行中機能的電気刺激療法の即時効果 三次元動作解析システムを用いた検討

MORISHITA Soichiro; YOKOI Hiroshi
When an accident or a malfunction with automatic machines occur, the foreknowledge possibility of the engineer who designed them is often alleged. In general, opinions of experts are taken seriously than opinions of people who do not have expertise. If it is shown with objective evidence that it is unexpected malfunction even for experts, the foreknowledge possibility is denied. The expert can make a proper decision based on expertise about the coverage of the automatic machine. On the other hand, the person who does not have expertise becomes careful about the handling of the automatic machine and may underestimate the coverage. When the malfunction that an expert cannot foresee under such situation occurs, the result accords with the forecast by the person who does not have expertise by chance. Then, the engineers are questioned excessive responsibility. This tendency is in particular remarkable about a computer system. In this paper, the case that a user of the Okazaki City Library was arrested is shown as a case study of this problem. Moreover, with the perspective about a design of the automatic machine and engineering ethics, we discuss it as the internal security issues that authors have considered., The Institute of Electronics, Information and Communication Engineers, 02 Dec. 2010, IEICE technical report, 110, 321, 27-30, Japanese, 0913-5685, 110008675549, AA11651731 - BMI研究の最前線 基礎-臨床、医学-工学の連携 ヒト皮質脳波を用いたBMI臨床応用への統合的アプローチ(Frontier of Brain-machine Interface: Collaboration between Basic and Clinical Neuroscience Integrative BMI approach for functional restoration using human electrocorticograms)

YAMAKAWA Akihiro; KATO Ryu; MATSUSHITA Kojiro; YOKOI Hiroshi; ARAI Tamio
Robotics technology nowadays provides tools that can help us overcome several incapacities, as instance, power assisting devices for hemiplegics. In this paper we analyze the difference on the walking of a semi-paralyzed left leg hemiplegic patient with and without assistance provided by a walking assistive device developed at our laboratory. In order to analyze the effects of the assistance, we use electromyography sensors placed on both legs to measure the muscle activation, along with pressure sensors on the feet soles and bending sensors place on the hips and knees joints. Our results show an increase on the walking frequency, as well as, an increment on the muscle activity on the semi-paralyzed leg, against a decrease of muscular activity of the healthy leg. Pressure and bending sensors also show an increase in the legs movement. This results show the beneficial effects of using the assistive device., The Japan Society of Mechanical Engineers, 11 May 2007, ロボティクス・メカトロニクス講演会講演概要集, 2007, "2A2-F10(1)"-"2A2-F10(2)", Japanese, 110008695558, AA11902933 - 2A2-C10 A Proposal of EMG-to-Motion Classifier using Self-Organized Clustering
KITA Kahori; KATO Ryu; YOKOI Hiroshi; ARAI Tamio
To discriminate motion using electromyographic (EMG) signals, generally we measure EMG signals and instruct user's desired motion to system directly using a keyboard, and training data is generated. But it's difficult to discriminate motion exactly with this method when the number of motion is increased, because the feature space of each motion's training data will be overlapped. Therefore, in this research, we proposed a method to classify EMG signals using self-organized clustering and create training data. Then, we conducted some experiments of motion discrimination using proposal method., The Japan Society of Mechanical Engineers, 11 May 2007, ロボティクス・メカトロニクス講演会講演概要集, 2007, "2A2-C10(1)"-"2A2-C10(2)", Japanese, 110008695522, AA11902933 - 1A2-K09 Development of Walking Assist Machine Using Modular Wire Driven Mechanism

In this paper, the walking assist machine for leg paralysis users is proposed. The proposed walking assist machine is designed as a modular package based on wire winding up type pulling mechanism. This modular package allows us to replace it at the any position where we need to be supposed. In the experiment, this modular package installed in the hip part and toe part, and the performance was evaluated. As a result, it was able to be confirmed that a modular package had an alternative function of the bi-articular muscle by flexion of knee joint and ankle joint at same time., The Japan Society of Mechanical Engineers, 11 May 2007, ロボティクス・メカトロニクス講演会講演概要集, 2007, "1A2-K09(1)"-"1A2-K09(2)", Japanese, 110008695143, AA11902933 - 2A1-M03 A Proposal of Evolutionary Design System Crossing Reality Gap on Locomotion Robot

An evolutionary design is suitable to perform optimization of both the morphology and controller of simulated robots for adaptive locomotion. However, the simulated robots do not necessarily achieve in real because the reality gap impedes. Therefore, we purpose to develop an evolutionary design system closing the reality gap by exploit morph-functionality to evaluation of the evolutionary design.

In the case of applying the learning ability to the rehabilitation robot, we should take into account learning ability of user (human). In this paper, we developed a prosthetic hand with an interference driven finger and wrist to grasp the object stably, and a EMG-to-motion classifier using on-line learning method to adjust to the change in human's characteristics at time. Moreover, we conducted experiments to discriminate eight forearm motions, with the results, a stable and highly effective discrimination rate was achieved and maintained even when changes occurred in the mapping. Lastly, we analyzed mutual adaptation between human and adaptable prosthetic hand using ability test and f-MRI, and clarified each adaptation process., The Japan Society of Mechanical Engineers, 2006, ロボティクス・メカトロニクス講演会講演概要集, 2006, "2P2-A18(1)"-"2P2-A18(4)", Japanese, 110008694272, AA11902933 - 1A1-D08 Dynamically Stable Locomotion Acquired by Coupled Evolution of Morphology and Controller of Biped Robot
Matsushita Kojiro; Yokoi Hiroshi; ARAI Tamio
In this paper, we investigated the morphology and controller of biped robots. We viewed them as design components that together can induce dynamically stable bipedal locomotion. We conducted coupled evolution of the morphology and controller of a biped robot, which consists of nine links and eight joints, and is actuated by oscillators without sensor feedback in three-dimensional simulation. As results, both pseudo-passive dynamic walkers and active-control walkers emerged, but the pseudo-passive dynamic walkers showed more dynamic stability than active-control walkers. This is because compliant components in morphology function as noise filters and passive oscillators. Finally, we have concluded that appropriate compliance is a key to achieving dynamical stability during locomotion., The Japan Society of Mechanical Engineers, 2006, ロボティクス・メカトロニクス講演会講演概要集, 2006, "1A1-D08(1)"-"1A1-D08(3)", Japanese, 110008693675, AA11902933 - 2A1-B35 Understanding Morpho-functionality by Building Robot : Robot Design using Plastic Bottles

We designed and developed a quasi-passive dynamic walking robot with swinging torso, and we confirmed it can climb up a slope in a certain condition from some experiments so far. We tried to use this walking robot for different slope inclination angle. First, we discussed the strategy of climbing up slope of variable inclination angle. We verified through presumption and experiments that the simplest way is to change the ankle angle depending on the slope inclination angle. Next, we verified the validity of the strategy by experiments of different slope inclination angle. Finally, we discussed on the treatment of contiguous/noncontiguous change of inclination angle with some experimental results., The Japan Society of Mechanical Engineers, 2006, The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec), 2006, 0, _2P1-B18_1-_2P1-B18_3, Japanese, 110008694138 - 2P1-S-045 Slope-climbing experiments of quasi-passive walking robot(Walking Robot 2,Mega-Integration in Robotics and Mechatronics to Assist Our Daily Lives)

KATO Ryu; YU Wenwei; YOKOI Hiroshi; KAKAZU Yukinori
Learning of bio-signal-to-motion classifiers would be influenced by the factors like muscular forces and postures of the motion-related body part. In this paper, we analyzed the influence of muscular force on individual characteristics (that is means map relation between a signal and discriminating motion) using a bio-signal information criterion, which is based on the concept of conditional information entropy. This criterion was possible to reflect more correctly the degree of complexity between clusters formed by bio-signal data compared with other criterion like DB measure and KL information criterion. An experiment on forearm motion discrimination under five muscular force levels (based on 10,20,30,50,70%MVC) was conducted to verify the influence. Results indicated that change in muscular force influences individual characteristics. In the case of muscular force with 10,50%MVC, it was found through evaluation by entropy that muscular force is not enough, since information for discriminating motion was less. Consequently, we concluded that the muscular force with 20 or 30%MVC was suitable, and it was important to feed back their muscular force level to user in order to abolish individual variation., The Japan Society of Mechanical Engineers, 14 Nov. 2002, FAN Symposium : Intelligent System Symposium-fuzzy, AI, neural network applications technologies, 12, 361-364, Japanese, 110002496714, AA1190206X - Movement Control of Erastic Network Robot
FUJII Masaru; YOKOI Hiroshi; KAKAZU Yukinori
This paper describes the research on movement control of an elastic network. An elastic network is a robot which has arranged the spring of a shape memory alloy (SMA) in the shape of a network in the shape of a lattice. reinforcement learning is used for control of movement in this research. reinforcement learning of a discrete value, and continuous value reinforcement learning is compared and each feature is clarified. As a result, although based also on the degree of a sampling, although re-learning is quick, optimal movement control cannot be performed in reinforcement learning of a discrete value. However, in reinforcement learning of a continuous value, although it was easy to obtain the optimal solution compared with reinforcement learning of a discrete value, it turns out that re-learning is late, The Japan Society of Mechanical Engineers, 14 Nov. 2002, FAN Symposium : Intelligent System Symposium-fuzzy, AI, neural network applications technologies, 12, 339-342, Japanese, 110002496697, AA1190206X - Evolutionary acquisition of behavior using a robot model based on spring-mass system
UEHARA Kazutoshi; YOKOI Hiroshi; KAKAZU Yukinori
In research of evolutionary robotics, the issue about the relation between morphology and behavior is seldom progressing. In this paper, as a basis of this research, a series of experiments which investigates the characteristics of evolution in behavior are made. Genetic algorithms (GA) are run with different designs of chromosomes and fitness functions. From the results, it is observed that individuals which move with various patterns of behavior are emerged according to the settings of GA. This observation suggests that the design of the fitness function is important to generate well-ordered behavior., The Japan Society of Mechanical Engineers, 14 Nov. 2002, FAN Symposium : Intelligent System Symposium-fuzzy, AI, neural network applications technologies, 12, 321-324, Japanese, 110002496680, AA1190206X - Design and Analysis of Endoskeleton-type Wearable Power Assist Device

The objective of this paper is to develop a wearable power assist device for muscle support in daily life, which should be compact and light weight. For realizing such a device, we propose a mechanical device with no rigid frame, instead utilizing a body structure of an individual, which is called an endoskelton-type wearable power assist device. We propose the principle of the endoskelton-type device, and then we examine the effect of the device and the burden to the individual's L5/S1 disc. Following the discussion, we develop the device and verify the effectiveness., The Japan Society of Mechanical Engineers, 14 Nov. 2002, FAN Symposium : Intelligent System Symposium-fuzzy, AI, neural network applications technologies, 12, 43-44, Japanese, 110002496486, AA1190206X - 外骨格式装置型腰部パワーアシスト機構の開発

In the case of classifying human's motion from electromyogram (EMG), it needs to estimate an attainment of operator's motor skill. This is because it is used to judgement of the adequate number of motion for the operator and to judgement of a necessity of the operator's training. However, previous works have not consider the attainment of motor skill. Accordingly, this paper proposes a quantification algorithm of the attainment of motor skill and appends it in our proposed EMG classifier. Experimental results reported that the attainment of motor skill enables to evaluate the operator's current motor skill. Moreover, comparing the attainment and a classification rate enables to discuss the sufficiency of information amount from the EMG signals., The Japan Society of Mechanical Engineers, 31 Jul. 2000, The proceedings of the JSME annual meeting, 2000, 1, 377-378, Japanese, 110002522310, AA11461871 - A Study on Construction of Distributed Multi Modules to Extract Features

マルチエージェント系による組織的行動の仕組みに関する基礎研究として粘菌という生物のアメーバ様運動のモデル化を試みる.アメーバ様運動の実現には体の各部が柔軟に変位しつつ系としてまとまりを持った運動の実現を如何に図るかが課題となる.このことをここでは簡単に系の整合性を図るという.横井ら[2]はVPMを用いたが,事前に試行錯誤を伴う問題向きパラメータの設定が必要であった.そこで,(a)実行時,動的に整合性を計算する仕組み,且つ(b)エージェントの情報処理量の軽減という2つの目的を持ち,粘菌の細胞集合[1]に見られる"場における情報生成"という概念をVPMに採用し拡張する.この様にマルチエージェント系によるアメーバ様運動の実現を計画し,現在システムを実装中である.本稿ではその概要を報告する., 06 Mar. 1996, 全国大会講演論文集, 52, 13-14, Japanese, 110002867082, AN00349328 - Adaptive Distributed System of Artificial Cells Using Vibrating Potential Method - An application to nTSP

積み木問題は記号処理の立場から多くのアプローチがなされてきた代表的な計画問題の一つである.そこでのアプローチは,問題を簡略化するために問題に含まれる物理的制約条件を無視し,記号論による探索問題を対象としていた.しかしながら,無視された物理的制約条件の中には,問題を解くうえで不可欠な要素が存在する.例すば,個々の積木の形状,積木間の相互作用,および,重力の影響などである.ここでは,これらの要素を考慮したうえで積木問題へのアプローチを試みる.そこで,複数の積木(ここではユニットと呼ぶこととする)の物理的相互作用と情報処理を分散処理システムとして実現するために,自律機械群のモデルとして表現することを試みる.また,このモデルを利用して,積木問題へのアプローチふ図る.具体的には,各ユニットの行動を制限するルールを波動場によって表現し,このルールを用いることにより,問題の解空間を探索する., 24 Feb. 1992, 全国大会講演論文集, 44, 207-208, Japanese, 110002888334, AN00349328 - A study on expression of memorized information by parallel connected units

工学的視点から記憶に関する多くの研究がなされてきたが、ここでは新しく、ユニット間結合を考慮した生命体モデルによって与えられるネットワークによる並列接続ユニット構造を考え、記憶情報を並列接続ユニット構造内の調和振動の重ね合わせによって表現することを試みる。知識情報処理を行なうネットワークの代表的なものとしてニューラルネットワークがある、ニューラルネットワークは、生体の能力の分散的情報処理機構を参考にして構築されたものであり、高度な記号列認識機能を持つ有効な情報処理手法である。ところで、生体の情報処理においては絶対的な距離情報が重要な位置を占めているが、ニューラルネットワークではこれを扱うことは困難である。そこで、この位置情報をも処理対象とすることを目的としてネットワーク内に伝播する情報を波動によって表現することを試みる。さらにこれらの情報を表現するフレームとして、これまでに構築してきた生体モデルを用いる。ここで、情報を波動によって表現することは、外界(環境)の三次元情報を中枢神経系内で一次元情報の位相差結合に落とすことであり、生命体モデルとは、生体内の部分機能を数理的にモデル化を行なったものである。生命体モデルに於てユニットとは、一つの機能単位としていて、それぞれのユニットはそのユニットが持つ諸機能の一つとして場の状態に応じて結合子を生成/消滅させる機能を有する。結合子はユニットから他のユニットヘの結合と情報伝播の媒体として生命体モデル内に表現されている。, 25 Feb. 1991, 全国大会講演論文集, 42, 122-123, Japanese, 110002886804, AN00349328 - 生命体モデル構築に関する基礎研究 : 波動場に於ける結合の記述

従来,生命体の特異的な構造・状態を積極的に維持する能力を有するところに注目して生命体の機能を数理モデルで表現することを試みてきた.それらは,要素同士の相互作用が不特定要素間に作用するモデルのみを対象としていた.しかし,現実には特定要素同士の結合及び結合の切断という操作が必要となるケースが多い.この様な問題定義の下にここでは問題向きにこれまで示してきた数理モデルを拡張することを試みる., 04 Sep. 1990, 全国大会講演論文集, 41, 95-96, Japanese, 110002880412, AN00349328 - A study on an adaptation modeling of bionic to the environment

日本学術振興会, 科学研究費助成事業 基盤研究(B), 横浜国立大学, 基盤研究(B), 本研究では，自己身体として身体認知を可能にするサイボーグ義手の開発とその方法論を構築し，生来身体に近づいた自然な操作感を実現する次世代の実用的なサイボーグ義手の実現を目的とする．2021年度の成果は以下の4点である． a)身体認知を促進させる体性感覚フィードバックの実現のために，義手を装着するソケット内に設置可能な超薄型多点振動シートを開発した．形状記憶合金を薄板に配置し，高速で伸縮させ薄板を振動させることで，厚さ2mm程度の柔軟な振動子を実現した．これにより，従来の10mm程度の振動子と同様の刺激・認識精度を実現した． b)操作集中や操作負担を軽減させる制御手法を実現するために，義手ハンドに超小型距離画像センサを配置し，距離画像を用いて深層学習により物体形状を認識し把持姿勢を決定し，筋電で把持動作の決定を行う手法を構築した．これにより日常生活動作の85%程度をカバーできる3種の把持姿勢，2種の手首姿勢に関して90%以上の識別率で手指動作の識別可能にし不自然な操作力が必要がなく操作可能となった． c)常時装着が可能な多自由度サイボーグ義手の義手装飾グローブの開発を行った．当初予定より開発の柔軟度を向上させるため，新たにゴムライク樹脂の3次元造形機を導入し，皮膚程度の柔軟さをもつ装飾グローブの造形を可能にした．さらに生体計測用ゴム電極を用いた超薄型の筋電センサバンドを開発し皮膚への密着性を高め安定的な信号計測を可能にした．手先重量300g，総重量1kg程度の上腕義手(手指自由度4，手首1，肘1)を開発した．4名の上腕切断者用の義手を準備をし，2022年度の身体認知の検証を行うための準備を行った． d)義手の長期使用における身体認知への影響を調査するための準備として，東海大学医学部，成育医療研究センターと連携し，筋電義手の被験者を募集し，参加同意や上肢機能の臨床評価指標を決定した．, 21H03300

日本学術振興会, 科学研究費助成事業 基盤研究(A), 電気通信大学, 基盤研究(A), 本研究は，前腕切断者用の筋電義手として，自由度の高い運動能力と感覚の代替機能の実現を目指して，指先の触圧感覚と関節角のフィードバック機構を有する5指ハンドの開発を行い，筋電制御システムを利用して，切断者の手指動作の再建の課題に挑戦する． 課題は，メカ開発とセンサグローブ開発の2項目からなる． メカ開発では，ワイヤー干渉駆動法を用いて軽量・多自由度・高出力を有する5指ロボットハンドを試作し，性能評価を通して改良し，筋電義手に適用可能な設計法を明らかにすることを目指した．2021年度においては，3名の成人前腕切断者に，試作した5指駆動型筋電義手を適用し，フィールドテストを行った．期間中3回のフィールドテスト評価では，自由度義手との性能差を，BBT（Box and Block Test）及びCarroll test等の評価試験によって比較し，有用性を評価した． 当多自由度義手は，国内2例目の筋電義手として，2022年3月31日，厚生労働省補装具完成用部品に指定された． センサグローブ開発においては，導電性シリコンを応用することにより，指先の触圧と関節角を計測し，これを振動子を用いて断端部ソケットに伝達することを目的として，開発を進めた．2020年度においては，さらに，感覚のフィードバックの方法として視覚への映像変化として情報提示を行う方法を開発し，前述の触覚と聴覚へのフィードバックとのパフォーマンス比較実験を行った．患者への触覚のフィードバック方法として申請当初はボイスコイルによる振動フィードバックを検討していたが，2021年度に再検討し，フィードバックの呈示装置として骨伝導イヤホンを採用することとし，有効性検証のため，聴覚刺激を行いながら日常生活音を聞き応答する二重課題法を行い，人の囁き声に当たる30～40dBの小さな音に応答できること，これが日常生活を阻害しないことを明らかにした．, 18H03761
Apr. 2018 - Mar. 2023 - Complementary multimodal biosiginal measurement and analysis for prosthetic hand control
Jiang Yinlai
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), The University of Electro-Communications, Grant-in-Aid for Scientific Research (C), Surface electromyography (sEMG) has been widely investigated as a biological signal from which motion intentions can be recognized to control prosthetic hands. The availability and quality of sEMG can limit the usability and intuitiveness of advanced prosthetic hands that can restore most necessary hand movements. This study introduces force myography (FMG) as a supplementary signal and develops a hybrid sensor to measure sEMG and FMG signals simultaneously. Furthermore, a layer-fusion convolutional neural network (CNN) was proposed to analyze the sEMG and FMG signals. The recognition results of hand motion showed a significantly improved classification accuracy (CA) of the hybrid sEMG and FMG with respect to individual modality due to the rubustness of FMG. The FMG-assisted sEMG sensing approach can effectively offer great potential in the clinical application of sophisticated prosthetic hands without increasing burden to the user., 19K12877

MUKAI Masaya
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), Tokai University, Grant-in-Aid for Scientific Research (C), The minimum length of the HALS incision is 50 mm. Also, the hands and fingers of the operators are at risk of burn injury and the range of hand movement is restricted. To address these shortcomings of HALS, we have studied a 5-finger robot hand with a similar size to a child’s hand and the functionality of a normal hand. In collaboration with an engineering group, we have investigated whether such a hand could be developed to perform robotic HALS clinically. We have been granted several patents for a modified robot hand system that was originally developed for an electronic hand. The robot hand can perform the surgical procedures required for HALS and folds vertically at the palm to reduce its size for insertion through the incision. Furthermore, we are developing an exoskeleton signaling system with pressure sensors incorporated into the tips of the robot fingers to provide pseudo-tactile sensation for the surgeon., 17K10656

Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, The University of Electro-Communications, Grant-in-Aid for Young Scientists (B), In this study, we aimed to model a mechanism of voluntary control of human multi-muscle, and apply it for controlling EMG shoulder disarticulation prosthesis. First, a notion of voluntary control was introduced to the framework of muscle synergy analysis. Then, our experiments demonstrated that voluntarily activatable muscle synergies could be extracted by using an appropriate index. It was also suggested that the muscle synergy is not a minimum unit of voluntary muscle control. Moreover, we applied the notion of the synergy freezing degrees of freedom to the EMG shoulder disarticulation prosthesis system so as to control its robot-arm movements by low degrees of freedom input. As a result, both-shoulder amputee user could use our developed EMG shoulder disarticulation prosthesis to pick an object and place on it. Above results showed the usability of our proposed notion “humanize-robotics.”, 17K17724
01 Apr. 2017 - 31 Mar. 2019 - Nerve-Machine Interface and myoelectric hand for upper limb amputation.
Takagi Takehiko; YOKOI Hiroshi
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Grant-in-Aid for Scientific Research (C), An amputated nerve transferred to a nearby muscle produces a detectable electromyographic signal corresponding to the transferred nerve; this technique is known as targeted muscle reinnervation (TMR). It is optimal to select and transfer each motor fascicle to achieve highly developed myoelectric arms with multiple degrees-of-freedom motion. Each median nerve fascicle was transferred to the long head branch of the biceps or the brachialis branch, while the short head branch of the biceps was retained for elbow flexion. Each radial nerve fascicle was transferred to the medial or lateral head branch of the triceps, while the long head branch of the triceps was retained for elbow extension. Functional and electrophysiological improvement was noted, with marked improvement in the identification rate for each digit, forearm, and elbow motion after the selective nerve transfers. More selective nerve transfers may be required for the development of prostheses with multiple degrees of freedom., 16K10875

Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Challenging Exploratory Research, The University of Electro-Communications, Grant-in-Aid for Challenging Exploratory Research, Surface electrodes are required to measure the EMG (Electromyography) signals for the control of myoelectric prosthetic hands. This study developed conductive silicon by mixing silicon with aggregative carbon black. The conductive silicon was applied to metallic non-woven fabric to create materials for the electrodes. Since the electrodes are supposed to be used between the skin and the socket, the influence of force to the quality of the EMG signal was investigated. The electrodes were encapsulated in insulating silicon to be applicable to circumstances with sweat or water. Furthermore, a pressure-sensitive sensor was developed with the conductive silicon, which can be integrated into the prosthetic hand to provide sensory function., 16K12951

Mori Koichi; SEKI Tatsuya
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), National Rehabilitation Center for Persons with Disabilities, Grant-in-Aid for Scientific Research (C), The deafblind persons who have suffered visual impairment after hearing impairment or both after adulthood experience relative difficulty in learning Braille, so that the means of information acquisition tend to be limited to tactile sign language or finger spelling and the like. However, since these means are dependent on human assistance including tactile sign language interpreters, it is difficult to acquire information independently, which is a major cause of deterioration of quality of life (QOL). The aim of this research was to enablethose deafblind people who cannot use Braille, independent information acquisition with a signing robot hand. A hand and arm robot that mimicked a human right hand and arm with multiple degrees-of-freedom was developed that can produce tactile finger letter signs sequentially as output from a text entered at the console or from a text file., 26350691

Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Challenging Exploratory Research, The University of Electro-Communications, Grant-in-Aid for Challenging Exploratory Research, Functional Electrical Stimulation (FES) is considered effective to recover the motor function of the paralytic by inducing muscle contraction with paralytic electrical stimulation. However, the strong fatigue and avoidance response when using FES is yet to be overcome in order to improve its effectiveness and acceptability. This study therefore developed a muscle fatigue evaluation method according to the frequency characteristics of the electromyography associated with FES, and elucidated the relationship between FES parameters and the induced body movement and cortical activation. The FES device developed based on the findings of this study was validated by subjects with leg paralysis.

2007 - 2009 - Task assignment methodology of multiple tasks with order constraints for multiple robot system
OTA Jun; ARAI Tamio; YOKOI Hiroshi; CHIBA Ryousuke; UEDA Ryuuichi
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), The University of Tokyo, Grant-in-Aid for Scientific Research (C), In former researches in mufti-robotics, in spite of its importance, there have been no propositions of task allocation scheme toward the problem involving "task constraints" that impose some restriction on the orders of task execution. In other studies involving task constraints such as job shop scheduling, task constraints are given by the designer. We address the problem that robots should calculate task constraints by themselves and should execute task allocation considering their constraints. As an example of such problem, we adopted rearrangement task of multiple movable objects. In this research, following subjects should be solved. 1. Task allocation should be executed considering task constraints. 2. Task constraints should be calculated as early as possible. Toward these subjects, we have obtained following results. 1. By means of classification of task constraints, we have obtained calculation methods of task constraints and task allocation methods considering these constraints. 2. We have promoted efficiency of calculation procedure of task constraints. First, we have analyzed calculation procedure from viewpoints when calculation should be done and how long it should be taken. Next, we have listed all possible procedure. Finally, we have tested these procedures in simulated environments. As a result, following method turns out to be the most effective: In every time of task allocation, robots should calculate some constraints that costs comparatively low calculation costs. And robots should calculate other constraints that cost comparatively high calculation costs only when robots fail to planned tasks. In future works, more flexible framework that divides given task into several small tasks is needed. For example, some objects should be temporarily set to adequate intermediate goals., 18500148

2005 - 2006 - Development of a actively adaptable system to exploit the remaining function of upper limb amputee
YOKOI Hiroshi; YU Wenwei; WATANABE Ichiro; ARAI Tamio
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), The Univesity of Tokyo, Grant-in-Aid for Scientific Research (B), In order to reconstruct and the mobility function in upper limb amputations, during the course of this study we performed an automatic analysis of all possible remaining functions for amputees.In addition, in order to generate new functions we developed an actively adaptive system. The fruit of research obtained in 2006 fiscal year is as follows. 1) We established an intended motion prediction method with adaptive function for timely changing individual parameters. During the 2006 fiscal year, under the active search theory using a self-organizing map we looked for the remaining functions in the stump for upper limbs, eliminating the timely changes in the training data, we performed a online learning algorithms that allowed for an stable motion discrimination over long periods of time without loss of identification success rate. 2) We developed an 8 motions discrimination system using an small type UNIX server (gumstix) with the capacity to acquire EMG signals using the robotix module in order to improve the portable electromyogram (EMG) controlled prosthetic hand system constructed at our laboratory. Without losing performance from the high performance personal-computer based motion discrimination system we successfully implemented a completely portable EMG controlled prosthetic hand system with the possibility to discriminate up to 8 different hand motions with a control response time higher than 0.1Hz. 3) In addition, in order to improve the mobile implementation, we performed an evaluation test for a long period of time (6 months) using the system described above in order to confirm the continuous adaptation of individual characteristics. The system is currently being evaluated by a 50 years old right hand amputee woman. 4)Since last year, we used an functional magnetic resonance imaging (fMRI) to measure the effects in the amputee's brain over the use of the high performance portable EMG controlled prosthetic hand system. The investigation showed that as a result of the adaptation to the prosthetic system the amputee's brain presented activation in the somatosensory and motor cortex areas and the frontal lobe (area in charge of processing new information) presented a reduction in activation. Even more, the patient presented an perceptual illusion of ownership of the prosthetic hand. We think this is due to the information acquired from the appropriate visual and somatosensory feedback application. 5) As an application of the active search theory for remaining function, we developed a walking assistance system that makes use of the leg's remaining function in a left leg hemiplegics patient. The system drives the leg using the body's involuntary reflex system that remains intact in the patient aiming at the patient's walking improvement. As a result of the system implementation, the person presented an improvement in body position and walking speed., 16360118
2004 - 2006 - Intensive Training Therapy with Functional Electrical Stimulation for Recovery of Walking Function in Hemiplegics
YU Wenwei; YOKOI Hiroshi; TATSUOKA Hozumi
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), Chiba University, Grant-in-Aid for Scientific Research (B), The purpose of this study is to develop the intensive training therapy with the assists of functional electrical stimulation to help the recovery of walking function in hemiplegic patients. To realize the purpose, we developed a walking training station which consists of 1) a split-belt walking machine that can enable perturbed walking, 2) a support frame that could allow the patients to do safe training, 3) a functional electrical stimulation system that could not only assist the normal walking for hemiplegic patients, but also improve the balance maintenance of patients by artificial reflexes, 4) a set of measurement devices to monitoring the patients' walking. Besides, we also developed a neuro-musculo-skeletal model which could be used to compare and analyze both the normal walking and perturbed walking. Using the walking training station and simulation, a series of gait experiment and computer simulation experiment were carried out. The followings are the results and discussion. 1) The reflexive responses are phase-dependent. That is, different phase of perturbation occurrence would cause difference reflexive responses. Especially, the phase difference resulted in the amplitude difference of muscle activity, rather than the difference of response latency. The walking assist should also take the perturbation occurrence into consideration. 2) The simulator with a reflexive pathway which was implemented by using the EMG profiles acquired and processed in gait experiments with slip perturbation, could respond to the slip perturbation and recover from the perturbed gait to keep walking. That is, the reflexive pathway could improve the perturbation-resistance for walking. 3) When constructing the control system for assistive devices, time varying and individual dependent users characteristics should be taken into consideration, so that, the users could be appropriately assisted. An interaction based learning method was proposed and applied to acquire not only the control mechanism of FES, but also the perturbation occurrence detection system adaptively. 4) Patients received training on the walking training station. With the assist of FES, the training on the station could improve not only the posture and the speed during walking, but also the motivation of patients. 5) Using the walking speed on walking training station, and symmetricity of the walking as the indexes, the training effect could be evaluated. The evaluation before and after the training showed that, the training could improve the walking function of patients., 16300178

Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), HOKKAIDO UNIVERSITY, Grant-in-Aid for Scientific Research (B), In a snowfall region, snow-removal work during winter is hard work. Then, the purpose of this study is development of the autonomous work support module for snowplows carried out snow-removal work autonomously. In order to make a snow-removal work autonomously, it is necessary to detect an on-the-snow obstacle and an in-the-snow obstacle when the weather or temperature condition changed. Therefore, in this research, we use sensors that are a pyroelectoric infrared sensor, a reflected infrared sensor, and an ultrasonic sensor for on-the-snow obstacle detection, and a metal sensor for in-the-snow obstacle detection on the autonomous snowplow. Moreover, GPS was carried in order to detect own position. Using the experimental model which carried these sensors and controller, an evaluation test of these sensors and a move control experiment of the move controller in outdoors environment were conducted, and the validity of an autonomous work support module was shown., 12555066

Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), HOKKAIDO UNIVERSITY, Grant-in-Aid for Scientific Research (C), In this research project, the following three topics have been developed and investigated in order to realize the personal adaptable intelligent power assisting system. (i) Force control based on motion perception using Electricmiogram (EMG) signals In this system, it is necessary to consider an internal state of a human operator such as fatigue and slight changes of motion pattern, as well as conventional physical load. In this project, the method of representing the internal state with the EMG signals has been developed. Furthermore, the force control method with the internal state has been developed and verified. (ii) Modeling and analysis of individual motion perception Utilizing motion perception ability of an individual human operator, the power assisting system can become easier system to handle for him. In this project, we have focused on the system of wrist-elbow with three degrees of freedom, and we have investigated and modeled the interaction among the system. In addition, we have proposed the control system using the individual motion perception, and we have verified it. (iii) Development of power assisting device and its control We have developed two kinds of power assisting devices. The first one is a lightweight wearable one DOF device, and the other one is an external device of one DOF transnational motion. We have developed the personal adaptable control scheme by refining the above two control schemes, and we have applied it to the two devices. As a result, we have confirmed that the personal adaptable intelligent power assisting system, which can follow an arbitrary motion of a human operator with assisting force or torque, is achieved., 11835002

YOKOI Hiroshi
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), HOKKAIDO UNIVERSITY, Grant-in-Aid for Scientific Research (C), This research project is focused on the technical back-up for the people with spinal cord injuries to achieve the motor function, which was lost by an accident. The aim of this research is to develop a methodology on the adaptive control of the motorized prosthetics for individuals using a current LSI technology and an adaptive learning theory in order to measure and process the action potential signal of the dura mater of the spinal cord at the brain-side from the damaged area. The important components of this research are development of an adaptive classification method, reconstruction of a control function using FPGA (Filed Programmable Gate Array), classification of electrophysiological signals of a rat cranial dura mater for a new communication and control, and development of multi-site electrode using micromachining technology. The findings achieved by this research are as follows. 1. We applied the adaptive learning theory to classify the human electromyogram as the signal including the differences of individuals, and performed to control the prosthetic hands. As a result, the adaptation for individuals and stable classification was verified, and the adaptive learning theory was effective. 2. We measured from cranial dura mater, which is closer to the sensory cortex, in an anaesthetized rat electrophysiologically.. The cluster corresponding to the stimuli was generated by the off-line time series analysis using the adaptive learning theory. 3. With the same method, we measured the signal from the area, which is concerned with the control of the lower limb, above the Layer-I of the motor cortex using electrodes located at cranial bone. And the result showed the possibility of classification and extraction for the signal corresponding to the movement of lower limb. 4. We developed multi-layer, multi-site implantation microelectrode. And the measurement of the signal from the dura mater of the spinal cord with the various implantation methods using wire-electrode or multi-site electrode is tried. 5. The signal processing system executable to synthesize an intended mapping function and the experience system by using FPGA was developed. The experience showed that this system has the computability to synthesize the signal processing circuit on the learning theory and the capability of the effective high speed processing in terms of parallel processing. Conclude this research : The aim of this research is to develop the device to classify the signal for individual's characteristics of action potential as the real-time adaptive processing system. For this purpose, we performed to construct adaptive classification method for nerve signal, and showed the possibility of synthesis of the signal processing circuit on the learning theory by FPGA for real-time processing. With considering the result of animal experience, we serve as a stepping-stone to develop the intelligent motorized prosthetics by adaptive classification of signal on the dura mater of the spinal cord. And we made the result of these researches public for dissertation and so on., 10838004

KAKAZU Yukinori; YOKOI Hiroshi
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), Hokkaido University, Grant-in-Aid for Scientific Research (C), The automatic operations of loading and unloading are one of the most important research themes of factory automation in industry. However, this type of problem is classified into the large scale of scheduling problem that is difficult to solve using combinatorial optimization techniques. For these problems, multiple and cooperating schedulers method has been proposed that is based on parallel computation and distributed autonomous computation. Such method is useful for quick computation by the reasonable schedulers that has a distributed function of computation load. So how to design the reasonable schedulers becomes the key point of this automatic operations of loading and unloading problem In this research, we propose IPD architecture based on mathematical model of competitive systems. For the automatic loading and unloading problem, autonomous small robots are designed that has two functions of scheduling and loading. The scheduling function is improved by the feedback of evaluating value which is sum of efficiency of robot's work. This improvement is a self-learning process of the proposed architecture based on prisoner's dilemma. This report shows theory of proposed IPD architecture and results of loading and unloading problem. As a result of this research, the hybrid problem of cooperating loading and unloading operation is solved by new concept of competitive computation of IPD architecture. The IPD architecture is applied to the autonomous scheduling robots group, and the result shows self-learning function of improvement of scheduling capability. Basic phenomena of social system of autonomous robot group is shown and published., 09650284

Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), HOKKAIDO UNIVERSITY, Grant-in-Aid for Scientific Research (B), The mechanism of human sense and behavior is a highly complicated nonlinear information processing system that is obtained by adapting to the complex environment. There are various complex phenomena. e.g.. a transition between various behavior patterns, a competitive recognition of multiple meaning, and, chaotic dynamics in biological systems, etc. In order to understand such human information processing, a research of human system, as a complex adaptation system, becomes very important. The fundamental goal of our research is to construct a measurement system of human cognitive behavior and to integrate various levels of human activity from biological level to behavioral and cognitive level, In this research, we mainly focused on the following three subjects as bases of such study : 1. Analysis of biological nonlinear dynamics. 2. Self-organized information processing. 3. Interactive measurement of human behavior. 1) The extraction and characterization methods of biological internal dynamics were investigated. Here we developed a concept of dynamic real-time characterization of biological dynamics and applied to the analysis of human blood flow dynamics. 2) The adaptive learning method for multi neural agents system was investigated. For the pulse neural network, we developed the method of spatio-temporal self-organized learning and applied to a binding of sensory information. 3) We constructed the interactive system between human and computer agent. Here we investigated how the behavior of agent influences human mental state and understanding of the agent. Through these studies, we developed a basic framework to handle a non-explicit human information such as physiological or mental factor of human system., 08458083
