JUNIOR DESIGN PROJECT
Sumo Wresting Robots

Herbie, as he is nicknamed, is a 68HC11 microprocessor control autonomous robot. Designed with optical and tactile sensors, his goal is to seek out his competition and then push him outside of a white ring marking the playing field.

Herbie is built upon the hollowed chasis of an RC racing car fitted with a white tupperware bowl. His main drive train and steering systems are both built with an H-bridge controller, and his speed control is achieved using a pulse width modulation signal from the microprocessor.

Though his performance in the ring was overshadowed by a lack of motor torque, Herbie functioned as he was designed. You can download the assembly code here.
