The strongly made Rover 5 tracked chassis from Dagu Electronics is an excellent base for tank style robots. A unique design allows the tread height to be adjusted for extra clearance. Independant motors for each wheel include quadrature encoders for precise control. This version has 2 motors with encoders - one motor per rear wheel.
Rover 5 is a new breed of tracked robot chassis designed specifically for students and hobbyist. Unlike conventional tracked chassis’s the clearance can be adjusted by rotating the gearboxes in 5-degree increments. “Stretchy” rubber treads maintain tension as the clearance is raised.
Each gearbox has an 87:1 ratio includes an optical quadrature encoder that gives 1000 pulses over 3 revolutions of the output shaft.
Inside of the chassis are 4 noise suppression coils at the bottom and a battery holder that accepts 6x AA batteries. It is recommended to use NiMh batteries as they last longer and have a higher current output than Alkaline batteries.
Expanding the chassis
The quickest way to get the 2WD Rover chassis moving is with the Dagu Rover 5 Explorer PCB. This includes motor drivers, voltage regulators, encoder support and lots of places to plug in servos and sensors.

The RP5 expansion plates from Pololu are also compatible with the Rover chassis. Both wide and narrow plates fit giving lots of space to add things on top.
