Prosthetic Hand

The cost burden of many commercial prosthetics is unfortunately too much for many amputees to endure. For my senior design project, we decided to design a low-cost prosthetic hand with a myoelectric system for a lifelike experience. The hand has an onboard micro controller unit (MCU) which implements a control algorithm for the six motor drivers within the hand. After training the myoelectric system which is worn on the limb, the user flexes their muscles for a desired hand orientation and the state is conveyed to the hand for the onboard MCU to  bring the system to its desired orientation. The internal gearing system within the hand was designed to avoid motor idling when a force is applied. The hand was successfully tested on an amputee and is currently being spun into a start-up.
