Romi Kit

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 Romi chassis has an abundance of general-purpose mounting holes and slots intended for various sizes of screws. These holes can be used for mounting your own electronics or the variety of Romi accessories we have available, such as the Robot Arm for Romi.
