Abstract: “ Prosthesis is an artificial approach, which is used to replace a disabled body part. Prostheses are typically used to replace and provide supplement to disabled/defective body parts. Disabled body parts can be of any reason like lost accidently, birth physical disability etc. The main requirement is that its function should be as natural as real arm. There are various designs of artificial arm that are available in the market, categorized as electrical, mechanical and Myo-electric arm. Mechanical prostheses use some motion of the body to provide the power necessary to control the prosthetic component. Electrical arms activate the hand by a motor which is driven by micro switches and relays. This paper effectively focuses on the ease of use, cost effective and simple to handle prosthetic arm for economically challenged

Keywords: Prosthetic hand, Disabled, Arduino, low cost,3D printing.
