INTERNATIONAL JOURNAL OF ADVANCED ROBOTIC SYSTEMS 14(5) 2017年9月 査読有りThis article proposes a virtual hand and a virtual training system for controlling the MyoBock-the most commonly used myoelectric prosthetic hand worldwide. As the virtual hand is controlled using the method also adopted for the MyoBock hand, the proposed system provides upper-limb amputees with operation sensibilities similar to those experienced in MyoBock control. It can also display an additional virtual hand for the provision of instructions on hand operation, such as the recommended posture for object grasping and the trajectory desirable to reach a target. In virtual hand control experiments conducted with an amputee to evaluate the proposed virtual hand's operability, the subject successfully performed stable opening and closing with high discrimination rates (89.3 +/- 6.65%), thanks to the virtual hand's incorporation of the MyoBock's operational characteristics. A training experiment using the proposed system was also conducted with eight healthy participants over a period of 5 days. The participants were asked to perform the box and block test using the MyoBock hand in a real environment on the first and final days. The results showed that the number of blocks transported in 1 min significantly increased and that the participants using the instruction virtual hand changed the orientation of the hand approaching blocks from vertical to lateral. The outcomes of the experiment indicate that the proposed system can be used to improve MyoBock hand control operation both quantitatively and qualitatively.

日本機械学会ロボティクス・メカトロニクス講演会講演論文集(CD-ROM) 2017 ROMBUNNO.2P1‐P08-P08 2017年5月9日<p>This paper is described about the design and operation evaluation of the skeleton type electric prosthetic hand for mass production purpose. Through changing an electric motor unit from a servomotor to a linear step motor in order to reduce power consumption against the previous prosthetic hand [4] [5] and through changing the initial shape of the glove were achieved. Then a user-evaluation was performed in order to check grip shape against various forms of objects.

日本ロボット学会誌 34(6) 404-410 2016年This paper proposes an interactive training system for control of myoelectric prostheses. The proposed training system is capable of selecting suitable motions (EMG patterns) for each user by eliminating ineffective ones, and can also provide consistency between user's motor images and the corresponding prosthetic movements using a virtual prosthetic hand (VH). In the experiments performed, a one-day training session using the proposed system was conducted with nine healthy males (including an experienced) and an upper limb amputee. In addition, EMG discrimination ability of each subject during VH control without any feedback information was evaluated before and after the training to verify the training effects of the proposed system. The results showed that the discrimination rates for selected motions were sufficiently high (98.9 ± 1.24%) by using the proposed selection method, and the accuracy in discrimination for VH control was significantly improved after training (for healthy subjects and the amputee at the 0.1% and 1% level, respectively). It is therefore confirmed that the proposed system can be used for myoelectric prosthesis control training.

This prosthetic hand has ability to grasp an object with adaptive prehension according to its form. Its finger can be moved similarly to the bending of the fingers of a person. 4 Fingers of this electric powered prosthetic hand can be controlled by conventional 2-channel electrode system through controlling of only one servomotor.</p>

ロボティクス・メカトロニクス講演会講演概要集 2015 _1P2-K05_1-_1P2-K05_2 2015年This paper proposes a training system for controlling the five-finger EMG-prosthetic hand that enables not only fast finger motions but also a strong grasping force. The proposed system is developed based on the control method equivalent to the five-finger prosthetic hand, and conducts three types of training: muscle contraction, muscle cooperation, and grip force training. In the contraction training and the cooperation training, the control ability of muscle force and the reproducibility of EMG patterns can be trained, respectively. Appropriate gripping force according to the hardness of an object can also be trained via the grip force training using a virtual prosthetic hand. The validity of the proposed system is demonstrated in the five-day experiments conducted for three subjects.

We modularized the ECS "Bio-remote" developed at Hiroshima University based on OpenRTM. The modularity enhanced flexibility and expandability of Bio-remote, and it made possible to operate by combining multiple input signals. In addition, we performed a trial test with an upper limb amputee in a room which was build to evaluate Bio-remote. We confirmed the operation of the prototype system and the advantage of the modularity that the system function can be easily modified and added.

In the experiments performed, a one-day training session using the proposed system was conducted with two healthy males. The results showed that the number of motions was gradually increased through training and the discrimination rates for selected motions were sufficiently high (average discrimination rates: 95.7 ± 1.54 [%]). It is therefore confirmed that the proposed system could be used for myoelectric prosthesis control training.
