The Pololu round robot chassis is a robotic plateform to build your own round robot. This acrylic chassis is 3mm thick has a diameter of 127mm. Many general-purpose holes and slots will let you create your own custom robot with your own configuration of sensors and components. Two holes can be used with the 42×19mm wheels equiped with the Pololu micro gearmotors. It also can be used with the wheel encoder set.

The motors can be mounted on either side of the chassis so that it change height from the ground. With motors mounted on bottom of the chassis, you can use the Pololu 1" ball caster as a third point of contact with the floor. With motors mounted on the top of the chassis,  use the Pololu 3/8" ball caster with the included 1/16" spacer for a best fit.
