Voice Recognition based robotic hand for handicapped people

Project Title

Voice Recognition based robotic hand for handicapped people

Project Area of Specialization RoboticsProject Summary

The prime aim of this project is to make the Robotic hand based on voice commands given by the user. This robotic hand will be very useful in different situations and applications involving the medical field as well as other fields where human interaction is challenging and unsafe. The main intention of developing the robotic hand is to use it in the medical field to assist physically disabled people. Moreover, the biggest advantage of these hands is that it can work in hazardous areas which may not be safe for human workers. In this project, we will design a novel active prosthetic hand with multiple fingers. The potential benefits of such an active prosthetic hand are as follows. First, an active prosthetic hand will provide the capacity to do real work, mimicking the movement capability of a real hand and therefore improving the living standards and/or comfort of people who have lost their hand(s) for a variety of reasons. Second, a prosthetic hand with a proper cosmetic design and/or appearance will foster the self-esteem of the subject.

Project Objectives

Prosthetic hands are devices designed to help those with full or partial hand loss retain the function and appearance of a regular hand. Basic prosthetic hands are cosmetic replicas with only basic functions. Whereas innovative electric prosthetic hands have a set of fully articulated fingers. The main aim is to develop a prosthetic hand that more close to the real ones in the function to help the people who lost their hand.

Project Implementation Method

We will first design a novel multi-fingered prosthetic hand with the ability to pick up and releasing objects. The prosthetic hand employs 3 DC motors /Servo motors and gears to transfer motion to the linked parts of the fingers. We will use flexible thin-film resistive force sensors at the fingertips of the prosthetic hand to adjust the grip force at the fingers. The second part of the study will involve the use of speech recognition to control the prosthetic hand. The control circuit will consist of an HM2007 speech recognition IC/Voice recognition module V3 and a PIC microcontroller to drive the DC motors /servo motors moving the fingers. We will implement both the prosthetic hand and its speech recognition-based control electronics.

Benefits of the Project

The potential benefits of such an active prosthetic hand are as follows. First, an active prosthetic hand will provide the capacity to do real work, mimicking the movement capability of a real hand and therefore improving the living standards and/or comfort of people who have lost their hand(s) for a variety of reasons. Second, a prosthetic hand with a proper cosmetic design and/or appearance will foster the self-esteem of the subject.

Technical Details of Final Deliverable

The servo/Dc motors of hand  are controlled by bluetooth/Voice recognition module.The motors come in position to pick and drop something based on voice commmands given by the user.User can also stop motor by using voice command.
