Prototyping a Prosthetic Arm for Ulnar and Radial Deviation

This study presents a design of a prosthetic arm which is intended for transradial and wrist disarticulated amputees. The prosthetic wrist aims to perform ulnar and radial deviation. It incorporates a Myo Ware muscle sensor and integrates it with an Arduino Uno to actuate the servo motors which can drag the load of a mannequin hand. Surface electromyogram (EMG) signals that is gathered from the forearm are used to control the angle of servo motors.
