Title: SYSTEMS AND METHODS FOR PROSTHETIC WRIST ROTATION
Abstract:
Features for a prosthetic wrist and associated methods of rotation are described. The prosthetic wrist attaches to a prosthetic hand. Rotation of the prosthetic wrist is performed in combination with grip formation of the prosthetic hand. An IMU provides data associated with the orientation of the prosthetic hand. A desired grip for the prosthetic hand is selected, for example by gesture control. A rotation for the prosthetic wrist is determined based on the orientation of the prosthetic hand from the IMU data and on the selected desired grip. The prosthetic wrist techniques can also be used in combination with prosthetic arms, elbows and/or shoulders. Example structural configurations for the prosthetic wrist and hand are also provided.
