The Pololu Pushbutton Power Switch is a compact, solid-state power switch that features built-in reverse-voltage protection and is controlled by a momentary pushbutton: one push turns on power and another push turns it off. This is a...

This breadboard-compatible module is an alternative to bulky power switches. It uses a small integrated slide switch to control a high-side power MOSFET that can deliver continuous currents up to around 6 A at 2 V to 20 V . The board...

These black plastic wheels press-fit onto the 3mm D shafts on many of our motors, including our micro metal gearmotors and our mini plastic gearmotors , to make a nice drive solution for small robots. The wheels have silicone tires and...

These tiny brushed DC gearmotors are intended for use at 6 V, though in general, these kinds of motors can run at voltages above and below this nominal voltage, so they should comfortably operate in the 3 – 9 V range (rotation can start...

The Zumo robot for Arduino is an Arduino-controllable tracked robot platform that is less than 10 cm × 10 cm—small enough to qualify for Mini Sumo. It includes two micro metal gearmotors coupled to a pair of silicone tracks, a stainless...

This kit contains most of the parts you need to build an Arduino-controlled Zumo robot. It consists of a Zumo Shield for Arduino, v1.2, a Zumo chassis kit, and a Zumo blade. You will also need a pair of micro metal gearmotors, four AA...

Overview The Pololu Zumo chassis kit contains the components necessary to build a small, high-performance tracked robot platform that is compact enough to qualify for Mini Sumo competitions. Each side of the chassis has an idler sprocket...

Use this motor driver and power distribution board to get your Romi chassis running quickly. It offers all of the same features as the smaller Power Distribution board for Romi Chassis — battery contact slots, reverse voltage protection,...

This set of six battery contacts completes the six AA battery holder molded into the Romi chassis base plate. A set is included in each Romi Chassis Kit. Notes Combined weight of all six contact pieces.

This is the main base plate for the Romi chassis, including the battery cover, in white . It is included as part of the white Romi Chassis Kit. Notes: Without Batteries.

This is the main base plate for the Romi chassis, including the battery cover, in black . It is included as part of the black Romi Chassis Kit. Note Without batteries

This power distribution board is designed specifically for the Romi chassis as a convenient way to access the chassis’s battery power and pass that on the rest of the electronics that make up your robot. It has slots for soldering...
