The goal of this project was to design and manufacture robotic joints that are inexpensive and capable of being used in a variety of applications. In order to maximize the number of applications in which our design could be utilized, research was done on optimal strength, size, communications, modularity, and price. This project includes the research and design development necessary to engineer such a joint, including part selection, motor control, manufacturing processes, and strength analysis. Two Joints were constructed and tested: a rotator joint and a elbow-joint. The joints performed well under testing conditions and overall prices were kept low. With future development, these joints could be used in fields where size and price are critical.
