Design of a gripping movement control system for a robotic hand prosthesis

Abstract:

In this paper, a description of a control system for basic grip movements for a low-cost hand prosthesis is presented. The idea is to provide movements to those people who do not have fingers due to congenital malformations, considering that the movements of their wrists are complete. The wrist movements are acquired by means of the Myo bracelet, which has wireless communication. The Myo bracelet has eight myoelectric sensors and an IMU, i.e., non-invasive sensors that are positioned around the forearm. The gestures read by means of the Myo bracelet are processed by the control system to send the commands to the small electric actuators installed in the prototype hand prosthesis.
