The Pololu Zumo chassis is a small, tracked robot platform that is less than 10 cm on each side — small enough to qualify for Mini Sumo competitions — and works with a variety of micro metal gearmotors to allow for a customizable combination of torque and speed. You can use this chassis as the base for your custom robot or get one of our more complete Zumo robots, which include electronics designed specifically for the Zumo chassis.

The video below introduces the first of these such robots, the Zumo robot for Arduino:
