Dagu Rover 5 Tracked Chassis with Encoders Overview Dagu Rover 5 tracked chassis, top view. Dagu Rover 5 tracked chassis with encoders, top view. 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 heightand, therefore, the clearance under its bodyby 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 ruer tracks maintain sufficient tension with several different gearbox angles, allowing the chassis height to vary by nearly 1.5 (3.8 cm).Dagu Rover 5 tracked chassis configured Dagu Rover 5 chassis configured in its in its default, flattened position. maximally elevated position. The outer dimensions of the chassis are approximately 9.5 long, 9 wide, and 3 tall in its default, flattened configuration (with the front and rear gearboxes mounted at an angle of 180 to each other).
