Overview

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.

The chassis is designed to work with these parts:

Tamiya 70101 Truck Tire Set (4 tires)

Tamiya 70144 Ball Caster Kit (2 casters)

Tamiya 70097 Twin Motor Gearbox Kit

PCB01A 5" Round Prototyping PCB

 

Will the Tamiya 70168 Double Gear Box fit on the Pololu Round Robot Chassis (RRC01) with no modifications?
You can mount the double gearbox to our round robot chassis without any modifications if you use the two gear ratios that position the axle closer to the motors (344.2:1 and 38.2:1). Using the the two gear ratios that position the axle farther from the motors (114.7:1 and 12.7:1) will cause the wheels to hit the chassis. Please note that the axle of the double gearbox will not go through the center of the circular chassis; it will be slightly off-center. The chassis was designed for the twin-motor gearbox, which looks a lot like the double gearbox but does not have the same dimensions (we designed the chassis before the double gearbox existed); if you use the twin-motor gearbox, the axle will go through the center of the chassis.
