In the perception-assist, user's dangerous motion is changed to safety motion when there is a possibility of accident such as the collision between user's body parts and obstacles. On the other hand, the joint motion of a human can be changed by using vibration stimulation on the tendon of muscle. By using this motion change method, there is a possibility that perception-assist by using vibration...
In order to assist the daily life motion of physically weak persons such as elderly persons, many kinds of power-assist robot have been developed. In the case of physically weak persons, perception ability to perceive the surrounding environment is often deteriorated also. A method of perception-assist has been proposed to assist not only the user's motion but also interaction of the user with his/her...
A sEMG signal is useful for the control of the wearable robots because its measurement is relative-easy and the joint torque can be estimated from sEMG signals of related multiple muscles. However, estimation methods of sEMG signals are not always available for all users. On the other hand, an EEG signal is one of the biological signals which might be the substitute for a sEMG signal because an EEG...
It may be difficult task for physically weak elderly, disabled and injured individuals to perform the day to day activities in their life. Therefore, many assistive devices have been developed in order to improve the quality of life of those people. Especially upper-limb power-assist exoskeletons have been developed since the upper limb motions are vital for the daily activities. Electromyography...
In the case of some elderly or disabled persons, not only the motor ability, but also the environment perception ability is sometimes deteriorated. To assist the daily living motion of those people, power-assist robots with the perception-assist have been proposed. The power-assist robot with the perception-assist assists not only the user's motion but also the user's interaction with an environment,...
In the case of some elderly whose motor ability is deteriorated, the environment perception ability is sometimes deteriorated also. In order to deal with that problem, the power-assist robot with the perception-assist, which assists not only the user's motion but also the user's interaction with an environment, has been proposed. The power-assist robot with the perception-assist has some sensors in...
In order to improve the quality of life of persons who lost their limb due to an accident or a sickness, many myoelectric artificial arms have been proposed. To control the motion of the elbow joint of the myoelectric arm, the EMG signals of the biceps brachii and the triceps brachii muscles are frequently used as input signals. However, since both muscles are the biarticular muscles between the shoulder...
