Romi Chassis Kits

The versatile Romi chassis is a great starting point for your next mobile robot. It is a differential-drive platform with a diameter of 6.5″ (165 mm) and an integrated battery holder for six AA batteries. The drive wheels are located on a diameter of the circular base plate, allowing for turns or spinning in place. A large, fixed ball caster in the rear provides a smooth third point of contact, and a second ball caster (not included) can optionally be added to the front. The chassis uses 70×8mm Pololu wheels and Mini Plastic Gearmotors with extended backshafts to enable quadrature encoders for position feedback.

The kits below, which are available in six different colors, include motors, wheels, one ball caster, battery contacts, and all other mechanical components required to assemble the chassis. The kit components are also available individually as replacement parts or for those who want to put together custom color combinations. This animation shows how the parts fit together:
