Design and Implementation of Haptic Prosthetic Hand for Realization of Intuitive Operation

Abstract

This project presents the design and implementation of a microcontroller-based voice activated wireless automation and hand movement system replicating using flex sensor system. As speech is the preferred mode of communication for human beings, this project intends to make the voice-oriented command for controlling the hand movements. The voice command is user independent. The system comprises of transmitting section and receiving section. Initially, the voice command is stored in the data base with the help of the function keys. Later the input voice commands are transmitted to through wireless device. The voice received is processed in the voice recognition system where the feature of the voice command is extracted and matched with the existing sample in the database. The module recognizes the voice and sends control messages to the microcontroller. This project also focuses on replicating the movements of the human hand using a plastic 3D printed hand simulation (hand frame). The flex sensors and servo motors work in co-ordination with ARDUINO to achieve this. The sensor sends the value to the ARDUINO, the ARDUINO processes the data and sends it to the servo motors. Based on the values provided the motor moves and thus the movement of the prosthetic hand is observed-replicating the motion of the hand.The functionality of the proposed project is based on myo-electric arm
