HandMECH and WristMECH are designed and developed as body-powered passive upper extremity prostheses. They can provide activities of daily living as simple approximations of human hand and wrist. Currently Pre-botic Hand and RoboWrist are under development to control the hand and wrist motions with minimized actuators. Actuators make use of also EEG, EMG signals for providing users to control their prosthesis as in biological counterpart. We’re looking for team members who are interested to work on any of these devices or bring new concepts.
