The Rover 5 tracked chassis, made by Dagu Electronics, is a durable robot platform with caterpillar treads that let it drive over many types of surfaces and uneven terrain. All you need to get the chassis moving is a robot controller or motor controller to drive the two built-in DC motors, which powered by the included 6-AA battery holder (AA batteries sold separately). A small Phillips screwdriver and an Allen wrench are included for working with the chassis.

The chassis features a rugged white plastic body with room to house the included battery holder and some additional electronics. The two powerful motors with 86.8:1 gearboxes are strong enough to lift the weight of the chassis and allow it to achieve speeds as high as 10 in/s (25 cm/s). We offer two versions of the Rover 5: with and without quadrature encoders; the encoders provide a resolution of 1000 counts per three revolutions of the wheel, or 333.33 CPR (counting both rising and falling edges of both encoder channels).

A unique feature of this chassis is the ability to adjust its height—and, therefore, the clearance under its body—by changing the angles at which the gearbox assemblies are mounted on the body. Interlocking teeth on the body and the gearboxes hold them in place and allow you to make adjustments in 5° increments by unscrewing a metal bracket inside the chassis, removing a gearbox, and reinserting it at a different angle. The elastic rubber tracks maintain sufficient tension with several different gearbox angles, allowing the chassis height to vary by nearly 1.5" (3.8 cm).

Expanding the Chassis

This chassis is compatible with our 1/8" acrylic RP5 expansion plates, which are available in narrow and wide versions and make it easy to add your control electronics, sensors, wireless modules, servos, etc. The plates feature flexible mounting hole patterns and include four tapping screws to mount the plate to the chassis (although we have noticed a misalignment between the mounting holes on the expansion plates and the Rover 5, so you might only be able to secure two of the screws on opposing corners).
