Zumo Chassis Kit (No Motors)

The Pololu Zumo chassis is a small, tracked robot platform that is less than 10 cm on each side, allowing it to qualify for Mini Sumo competitions. The main body is composed of black ABS and features a compartment for four AA batteries and sockets for two micro metal gearmotors. It ships as a kit with two silicone tracks, two drive and two idler sprockets, a 1/16″ acrylic mounting plate, and mounting hardware. (Motors and batteries are not included.)

The Zumo chassis uses two motors, one for each tread. The ideal motors for your robot depend on your desired torque, speed, and current draw, so motors are not included with the chassis. If you have limited ability to supply current, we recommend using lower-power non-HP motors, which have a stall current of 360 mA at 6 V; if you have the ability to deliver more current, the HP micro metal gearmotors offer more torque and speed for the same gear ratio.

We recommend either 50:1 or 100:1 HP or non-HP motors for use with this chassis, but 30:1 micro metal gearmotors might also work. Note that non-HP 30:1 motors do not offer much torque, so they are not very practical for sumobots, and HP 30:1 motors will make the robot extremely fast and difficult to control. The following table shows theoretical limits based on the motor specifications. Note that the specifications are for 6V operation, while four NiMH AA cells will typically provide less than 5V.
