Pololu 257 - Pololu Robot Chassis RRC01A Solid Blue

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 – you can save by getting them in one of our chassis completion kit. combination deals. 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.

If you have your own chassis design in mind, you can get a custom chassis and other custom robot parts made with our laser cutting service.
