Robotic Arm for the Easy Mobility of Amputees using EMG Signals

Abstract

A robotic arm is a Programmable mechanical arm to replicate the functions of human arm. They are widely used in industries. Human robot-controlled interfaces mainly focus on providing rehabilitation to amputees in order to overcome their impairment or disability leading them to live a normal life. The major objective of this paper is to develop a movable robotic arm controlled by EMG signals from the muscles of the upper limb. In this system, we mainly focus on providing a low 2-dimensional input derived from electromyography to move the arm. This work involves creating a prosthesis system that allows signals recorded directly from the human body. The arm is mainly divided into 2 sections, control section and moving section. Movable part contains the servo motor which is connected to the Arduino Nano board, and it helps in developing a motion in accordance with the EMG signals acquired from the body. Control part is the part which is controlled by the operation in accordance with the movement of the amputee mainly the initiation of the movement with respect to the threshold fixed in the coding. The major theme of the project is to provide an affordable and easily operable device that helps even the poor sections of the amputated society to lead a happier and normal life by mimicking the functionaries of the human arm in terms of both the physical, structural as well as functional aspects
