This rugged, 6-wheel-drive chassis from Dagu Electronics has independent suspension for each of its spiked 120mm-diameter wheels, allowing exceptional traction over uneven terrain
Its body is made from 2mm-thick anodized aluminum with a 10mm-pitch grid of 4mm holes, making it easy to mount electronics and accessories to the chassis. Assembly of the chassis is a simple three-step process that takes just minutes. This model is black with metallic-red hubs and has 34:1 steel gearboxes on the motors.
This rugged, 6-wheel-drive chassis from Dagu Electronics is designed to excel at traversing rough terrain and steep inclines, making it a great platform for any robot that needs to perform tasks in a complex outdoor environment. It features six powerful DC motors with brass brushes and 34:1 steel gearboxes that drive large (120mm diameter) spiked tires, and a unique “super-twist” suspension system acts to keep each wheel in contact with the ground for maximum traction, even when driving over uneven or bumpy surfaces. The suspension can be adjusted to suit different loads and conditions. The chassis is made from a 2mm-thick corrosion-resistant anodized aluminum plate, all of the nuts, bolts, and screws are stainless steel, and the brass fittings and suspension springs are nickel-plated.
When powered at 7.2 V, the version of the chassis with 34:1 gearboxes can reach a top speed of approximately 7 km/h (4.5 mph), and each motor has a stall torque of roughly 5 kg-cm (70 oz-in).
Using the Chassis
The chassis’ aluminum plate has 4mm holes spaced every 10mm, providing plenty of options when it comes to mounting your control electronics, sensors, and additional hardware, and with a maximum recommended payload of 5 kg (11 lb), this platform is capable of carrying a lot of cargo! Two compartments in the chassis have been designed to hold 7.2 V sub-C battery packs (not included) that are commonly used in RC cars. A total of four such battery packs can fit in these compartments. The interior of the chassis also features convenient screw terminals for connecting your battery and motor driver leads. The motor leads are pre-connected to these screw terminals.
This is a differential-drive chassis, meaning that turning is accomplished by driving the motors on the two sides of the platform at different speeds. The three motors on each side of the robot are wired in parallel, so only two channels of motor control are required to get this chassis moving. The motors are intended for a maximum nominal operating voltage of 7.2 V (2 V minimum), and each has a stall current of 6.6 A and a no-load current of 420 mA at 7.2 V. Since the motors will briefly draw the full stall current when abruptly starting from rest (and nearly twice the stall current when abruptly going from full speed in one direction to full speed in the other), we recommend a motor driver capable of supplying the 20 A combined per-channel stall current of these motors at 7.2 V.

If you are looking for a smaller, less expensive chassis, consider one of the Wild Thumper 4WD models
Note that while the Wild Thumper chassis includes six wheels, the wheels can be purchased in pairs for use as replacement Wild Thumper parts or as wheels for custom chassis. The wheels are available with metallic-red hubs and chrome-colored hubs.
Why not try it with Yukon?
Looking for a controller for your project? Yukon is a high-power modular robotics and engineering platform, built around RP2040 and designed to drive the most ambitious robots, props and devices.
