Romi Chassis Kit - Black

Overview

The Romi chassis is a differential-drive mobile robot platform with a diameter of 6.5 inches (165mm). The drive wheels are located on a diameter of the circular base plate, allowing for turns or spinning in place. A battery holder for six AA batteries (not included) is integrated into the chassis. A large, fixed ball castor on the rear provides a smooth third point of contact, and a second ball castor can be added to the front. The chassis uses our 70mm wheels and mini plastic gearmotors with extended backshafts to enable quadrature encoders for position feedback. The chassis is available as complete kit including motors, and components are also available individually for replacement parts or to make custom colour combinations.
