Structure And Movement Design To Build A Functional Prosthetic Hand, John Campbell

Honors College Theses

This project aims to create a functional prosthetic hand that will improve upon the previous design for this project. The previous design included four fingers which were moved using a four-bar linkage and slider crank mechanism in combination with a linear actuator to move all four fingers in unison. Two servo motors were used to create an opposable thumb that could be used to grasp objects. Movement of the prosthetic hand was activated using a signal received from a myoelectric sensor. The goal of this project is to study this design and attempt to upgrade the prosthetic hand utilizing a …
