Building the Romi Robot

The Romi chassis (Figure 6.2) is a differential-drive mobile robot 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 can be optionally added to the front.

The Romi chassis has plenty of general-purpose mounting holes and slots intended for various screw sizes, such as #2-56, #4-40, M2, and M3. These holes can be used for mounting your electronics, such as your microcontroller, motor drivers, and sensors:
