Robotic Hand

Project Title

Robotic Hand

Project Area of Specialization RoboticsProject Summary

Many assistive technologies implemented to help the disabled people. The purpose of this project is to design and implement a new mechanism for disabled people which can be used as a helping hand.It is completely non surgical which also helps to eliminite unbearable surgical costs. Generally, disabled people depend on others to live their lives. Our target is to make a robotic hand that has different characteristics to help the physically challenged people. The robotic hand will be able to move in any direction. It can be controlled from the movement of other hand via Bluetooth. The robot hand responds to move commands in the forward, backward, left, and right directions. A disabled person, especially those who do not have one hand can use this hand and perform activities like a normal person. The project also implements a robotic arm with pick and place capability. It is able to pick any object and carry it and place it to the required position. The robotic hand is designed such that it can be controlled by a number of different mechanisms, Disabled person can controlled his both hands by just the movement of one hand. The robot also uses an IP camera for video observation as well as video communication with others.

Project Objectives

The goal of the project is to integrate into society and improve the quality of life of person with disability of hand  by non-surgical and low-cost treatment as compare to the surgey.

Project Implementation Method

This model is constructed by servo motors and it can be controlled by the microcontroller. The motion deviations can be control through motor rotation. A servo gripper is fixed in the arm to hold the object. Initially all the motors are in the initial position,   and then the servo motor fixed at the shoulder part of the model is actuated so that the arm can be raised up and down. The elbow joint is operated by another servo motor which can move the arm front and back. The third servo motor is fixed at the wrist position of the hand. This is for the 360 degree rotation of the wrist part. The servo gripper (operated by servo motor) is fixed at the wrist position so that the gripper can hold the object to carry the object to another place DC motor with worm gear arrangement is fixed at the bottom of the total frame. This arrangement can rotate the model up to 360 degree. Two bearings are placed at the bottom of the upper model so that it can support the rotation of the hand to 360 degree. The whole process is controlled by the microcontroller.

Benefits of the Project

People with severe disabilities (amputated from one hand) can develop learned helplessness, which makes them lose interest in their environment. Robotic hands are used to provide an alternative method to engage in joint play activities. These robotic hands allows them to manipulate real objects in the context of perform activities.

Technical Details of Final Deliverable

A robot hand, with multiple fingers, designed to perform various tasks in daily life. Realization of the robot hand making flexible human-like motions by the design inspired by the human musculoskeletal system is expected.
