This 12 lb. robot was a collaborative effort from UCLA's Heavyweight Combat Robotics team. I was the Weapon Sub-team Lead for this project.Â
Weapon Design
This robot has a combination spinner and hammer arm weapon. As sub-team lead, I delegated tasks between project members and contributed to the design and fabrication of this sub-system. The spinner is powered by a pulley system (timing belts not pictured) connected to a brushless motor. The arm moves 180 degrees to attack opponents from either side and deliver a high kinetic energy impact.
The weapon arm involves a multi-stage pulley system. To reduce friction, we implemented ball bearings and bushings at each axle. To ensure a robust design capable of taking multiple hits from opponents, I created a test layout with multiple hole tolerances to determine the best dimensions for a press fit.
A scaled 3D printed version of the weapon system was printed to help identify challenging components to assemble and any design flaws.

This bot competed in several matches at a local tournament. In this environment, teams have to collaborate to quickly make repairs between fights.
