Project 01

Differential Wrist for Robot

Problem
The team needed a differential wrist design that could integrate with other subsystems and serve as a reference for future designs.
Solution
Designed a differential wrist mechanism with two degrees of freedom and rotation. Used X-contact bearings and a solid shaft for better reliability, even though the team initially wanted regular bearings and hex shafts.
Status
Manufacturing pending.
