Design and fabrication of prosthetic human hand using eeg and force sensor with arduino micro controller

This project deals with the design and development of a five fingered prosthetic hand for amputated persons. The design of the system is based on a simple, flexible and optimal control strategy that enables the person to use the device as normal arm. The hand system has independent commands to move the limb up and down and position the fingers precisely. Implementation of the mechanical hardware design of the human hand is based on connected double revolute joint mechanism. The tendon system of the double revolute joint mechanism and feedback network provides the hand with the ability to confirm to object topology and therefore providing the advantage of using a simple control algorithm. The model is should be fabricated with Servo motors and force sensors for fingers actuation. The entire setup is mounted on to the shoulder of the amputated person. Inputs for the motors can be generated through EEG signals generated from brain, which enables the user to grasp the objects with the way they think accordingly.
