3D PRINTED INTEGRATED FULL FUNCTION PROSTHETIC HAND-ARM SYSTEM

ABSTRACT A low cost anthropomorphic robotic full function prosthetic integrated hand-arm system is proposed, using 3D printing technology. Two methods of control are proposed for synthetic hand-arm system: 1. instrumented glove designed to imitate left or right hand to control the prosthetic hand. 2. using electromyography (EMG) signals generated through a sensor mounted on any muscle in the user's good arm. Simple tasks, requiring both the hands, can be achieved, by servomotor controlled finger motions. The rotation of servomotors, acting as actuators, is controlled using a microcontroller. The objective of the proposed work is to build a prototype of a controlled hand-arm system that replicates the full function hand and wrist movements towards the development of low cost solution of prosthesis for people with motoring disabilities.
