This Zumo robot is a low-profile tracked robot platform intended for use with an Arduino (or compatible device, such as an A-Star 32U4 Prime) as its main controller. It uses two 75:1 HP micro metal gearmotors to drive the treads, providing plenty of torque and a top speed of approximately 2 feet per second (60 cm/s). The Zumo robot includes a 0.036-thick laser-cut stainless steel sumo blade mounted to the front of the chassis for pushing around objects like other robots.
