Intelligent Bionic Arm

Project Title

Intelligent Bionic Arm

Project Area of Specialization NeuroTechProject Summary

Biotechnology has played a key role in revolutionizing lives. There is an incompleteness in the person’s personality after the loss and sometimes suffer acute depression and anxiety. This will lessen amputee depression acting as a service in the lives of those who have been through the traumatic experience of losing a limb. This will prove as an effective way for amputees to regain a sense of normalcy in their lives. The control task is to operate a functional bionic arm using electromyography by harnessing brain signals when a person attempts to move a limb providing complete prosthetic control. It will use a non-invasive brain machine interface to build a connection between a biological system and technology. The arm will have the ability of grip, rotation and bi-axial configuration. 

Project Objectives

The objectives of our project is that it'll revolutionize the lives of diabled people remarkably. It will give them a sense of completeness and make their living easier. Along with that our project is being done in a low cost budget. rather than using a myband sensor that increases the project cost incredibly we are using emg sensors that have reduced the cost effectively. 

Project Implementation Method

The project will have machine learning algorithms on which movements of the arm will be based. The simulation of microcontroller will be done on proteus. Atmega will be used for editing and compiling microcontroller program. Based on the movement of arm, the microcontroller will be programmed according to dc voltage level. The levels of the dc voltage corresponding to the EMG signals will be taken. We will then design a hand with 5 active fingers each having two joints whose motion will be controlled by a servo motor. The servo motor will be interfaced with an arduino. Another arduino will be trained to work with the emg sensors to provide signals to the servo motors on which it'll make the hand move. The bionic will intelligently function with the brain.

Benefits of the Project

The advantage of this technique is that the signal will be acquired from the patient's body and after suitable processing it is used as a control input to drive motors that are coupled to the prosthetic arm. So, the arm can be worn by amputees and the control mechanism will be initiated by their own EMG signals. The improvement of sensation, improved reintegration/embodiment of the artificial limb, and better controllability. This technology provides key advantages over traditional sensors, including high conductivity, compliance, flexibility and stretchability. This hierarchical multi-finger tactile sensation integration could provide a higher level of intelligence for artificial hands. Artificial limb can improve mobility and the ability to manage daily activities, as well as provide the means to stay independent.

Technical Details of Final Deliverable

A technical description is a document created for the end-user to understand how a product, process, or concept works. Loss of hand can cause many consequences in daily life. Numbers of opportunities is reduced because of hand loss. Hence, Research into producing a prosthetic hand that can be easily operated from the arm by the EMG signal is also a big step towards prosthetics. The prosthetic hand is having 5 servo motors. With this project, it was selected to save time using the open- source hand model option and the focus of this project is on electronics structure and embedded device coding, not 3D modelling. There is various type of open-source prosthetic hands printed in 3D available on the Internet. Five DC motors actuate the hand, one for each finger plus one for the thumb-opposition. Motors and sensors are scattered all over the house. The built-in control system contains a gesture control subsystem and a visual subsystem. The motion control subsystem is important as the sensory subsystem for both the amputee using a prosthetic and its control algorithms. The aim of this project to develop a low-cost, 3D prosthetic hand-printed using EMG. Though the final device has been fulfilled most of the initial steps, there are other aspects of the new layout that need to be rebuilt for real- life use cases.
