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.
This two-part aluminum assembly mounts directly to 4 mm diameter motor output shafts like those on our 25D mm gearmotors and allows you to drive most scooter, skateboard, inline skate, and other common wheels that are compatible with popular 608 ball bearings.
The m3pi expansion kit contains everything you need to turn your 3pi robot into an enhanced m3pi robot. The expansion PCB ships with all the surface-mount parts populated, but the included headers, buttons, and connectors must be soldered in.
This black polyurethane scooter/skate wheel measures 84 mm in diameter and 24 mm in width and works with standard 608 bearings as well as our Aluminum Scooter Wheel Adapters, which allow these wheels to be used with an assortment of motors.
These black plastic wheels are designed specifically for use with FEETECH FS90R micro continuous rotation servos. The wheels have silicone tires and measure 60 mm (2.36?) in diameter. Two additional mounting holes for 4-40 screws make it possible to use the wheel with several of our universal mounting hubs. The wheels are sold in pairs.
