Control of Simultaneous Motion in Shoulder Prostheses

This project developed a prototype electronic control unit to simultaneously execute motions in more than one joint of a prosthesis. The first phase established design parameters of the control unit by modeling the movements of a prosthetic arm and predicted the inertial forces acting on a moving prosthesis. The second phase built the motion control system and proved that digital signal processing can be used with analog technology to control simultaneous motions and counteract the predicted inertial forces.
