An Affordable and Fully Functional Bionic Claw Using Myoelectric Signals for Physically Challenged

For a person who lost their arm or an upper limb, even a simple task becomes cumbersome because of their disability. Prosthetics play an important role in helping these people cope up with the challenges they face. Swift developments in technology have resulted in powered myoelectric hand prosthetics entering the market but are avoided by many for being expensive to purchase and maintain. This paper outlines the development of an economical prosthetic claw that can be controlled by muscle signals. The project primarily aims to bridge the gap between cheap non-functional prosthetics and expensive fully controllable prosthetics by being affordable, durable, and easy to manufacture without sacrificing functionality. The claw and its components have been designed to be easy to modify, repair, and replace, making it a flexible platform for customization as per the user’s need. This translates to an efficient and feasible solution to the ever-growing need for affordable functional upper limb prosthetics for the physically challenged.
