Inspiration
CU Combat Bots is competing at UC Berkeley in a 3lb "Beetleweight" Combat Robotics competition on March 31st.
What it does
Titanium Joe is has a Combat Robot that can drive up to 15 ft/sec. It features an Egg Beater as its main Kinetic Energy weapon, which has a theoretical max energy of 240J, and tip speed of 1227 m/s.
How we built it
We used OnShape to design a test bed that was 3D printed before the hackathon. We used duct tape to mount most of the components to the bed, and nuts and bolts to secure the motors and motor mounts. During the event, the first prototype of the final body was designed in OnShape, but unfortunately was not 3D printed because it would have taken ~30 hours. An Arduino was programmed to translate signals from a receiver to the PWM waves for the motors.
Challenges we ran into
We had to redesign and reprint the motor mounts twice during the hackathon.
Accomplishments that we're proud of
It drives really well!
What we learned
OnShape is a great tool for collaborating on CAD designs.
What's next for Titanium Joe
Printing the first prototypes for the body, and attaching and testing the weapon system.
