Modeling and development of a prosthesis inspired by the anthropometry of the hand

Abstract

The present article describes the design, modeling and development of a mechanical hand prosthesis driven by myocardial impulses. The design of the prosthesis is based on the anthropometry of the hand, taking into account the skeletal shape of the phalanges and metacarpals, the connection mechanisms between phalanges, the system of flexor tendons and extension, ligaments and muscles. Through the signals from the muscles, the control system performs the operations of grip, rotation, etc. The control system consists of nano wreck, a motor controller, DC motors and the muscle sensor system.
