The Rover 5 tracked chassismade by Dagu Electronicsis 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 motorswhich 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 wheelor 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 andthereforethe 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 chassisremoving a gearboxand reinserting it at a different angle. The elastic rubber tracks maintain sufficient tension with several different gearbox anglesallowing the chassis height to vary by nearly 1.5" (3.8 cm).
