Design and Controlling of Low-Cost Prosthetic Hand Using Force Sensor

Abstract

Birth defects or several tragic events can result in the loss of a hand that can be physically and emotionally incredibly difficult to bear. In the study, a low-cost, prosthetic hand has been developed and managed, irrespective of geographical and financial conditions. It would be feasible and affordable to many people to create a prosthetic hand with basic materials, available in most areas and powered by servomotors, based on muscle motion detected by the use of Resistive Force Sensor (RFS). Due to its simplicity and low cost, the Arduino controller is used as a main control unit for the operation of this prosthesic. It is shown that throughout the experimental work it has been figured out that a developed low-cost prosthetic hand is working well and affordable. The findings of experiments indicate that the success rate for choosing big and light weight items is about 78%. But because of the simple lightweight materials used in constructing it, it cannot withstand large and small items very well.
