The Pololu round robot chassis is a compact 5-inch base, laser-cut out of colored acrylic, designed for small mobile robots. This circular chassis is intended for use with the Tamiya twin-motor gearbox, ball caster, and truck tires.

This circular laser-cut plastic robot chassis makes a great base for small mobile robots. With a diameter of only five inches (slightly bigger than a CD), this acrylic chassis is ideal for building sturdy robots capable of navigating tight spaces. The circular chassis has many holes and slots for mounting sensors, motors, and other hardware, and they come in a variety of transparent or opaque colors!

To complete the round robot chassis, you need the Tamiya twin-motor gearbox, ball caster, and truck tires. For a platform for your electronics you can use our 5-inch round prototyping PC board, which matches the chassis perfectly. The 1.25-inch standoff set also works well with the chassis.
