Wild Thumper 4WD (All Terrain Robot)
This rugged, 4-wheel-drive chassis is a smaller version of the Wild Thumper 6WD chassis. It is designed to move in rough terrain, making it a great platform for any robot that needs to perform tasks in a complex outdoor environment.
It features four powerful DC motors with brass brushes and steel gearboxes that drive large (120mm diameter) 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.
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.
