Export Quality 4WD Aluminum alloy DIY Robot car with motor and wheels Silver

Metal Tank Robot Smart Car Chassis Kit (with BO Motors & Wheels)

Build your own DIY robot tank or smart car using this 4wd robot chassis kit. This 4wd robot chassis kit uses a heavy-duty powder-coated silver frame and four 65mm direct-drive wheels, so you get a stable base for both tank-style and car-style projects. Because the platform is a metal chassis for robot builders, it handles sensors and controllers without flexing, and the included BO motors deliver smooth movement right away.

Unlike belt tracks, this design behaves like a true robot tank chassis with wheel traction. At the same time, it stays beginner-friendly: the 4wd robot chassis kit comes with pre-slotted mounting holes, wiring, and a 6×AA battery holder to help you start fast. If you want to upgrade later, the open layout of this metal chassis for robot makes add-ons easy.

Why choose this chassis

Whether you’re prototyping for competitions or teaching STEM, this 4wd robot chassis kit gives you torque, stability, and room to grow. The frame acts as a rugged robot tank chassis for outdoor surfaces, while the compact size suits indoor line-following or obstacle-avoidance tasks. With four BO motors already matched to the wheels, your build stays efficient and predictable.
