Prosthetic Hand Controlled Using Mind Waves

Abstract

The human hand is a part present in almost all human beings’ activities and the most intriguing and versatile appendage to the human body. Amputees face variant problems during their daily tasks even the simplest ones. There were many attempts thought out history to replace the effected limps with artificial prosthesis. This thesis introduces using NeuroSky Mobile2 headset to control a 3D printed prosthetic hand with five DoFs, using attention level and Iblink signals, servo motors are used to actuate the hand’s fingers through a group of artificial tendons, the user can choose either to operate the hand or not by generating an Iblink event, and the amount of attention controls the movement of servo motors, Arduino R3 port is used as the controller. This project resulted in a prosthetic hand which can achieve three simple task which are opening/closing hand and grasping an object.
