Export Quality 4WD Aluminum alloy DIY Robot car with motor and wheels (Black)

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

Build your own DIY robot tank or 4WD smart car using this export-quality robot car chassis kit. Designed as a strong and adaptable platform, this robot car chassis kit features a powder-coated black frame, four 65mm wheels, and BO motors, making it ideal for both indoor navigation and rugged surfaces. Because it works much like a 4wd car chassis while still supporting open hardware, it also integrates easily into arduino chassis projects for students and hobbyists.

Unlike belt-driven designs, the structure behaves like a compact robot tank while remaining lightweight. The included motors and wiring ensure the robot car chassis kit delivers smooth torque and simple installation. With plenty of mounting holes, this arduino chassis layout supports sensors, drivers, and controllers, making upgrades effortless. Its wheel-based traction also makes it a dependable 4wd car chassis for robotics learning paths.

This heavy-duty platform helps reduce assembly time, and because the robot car chassis kit uses direct-drive wheels, steering and motion control remain precise for both autonomous and RC builds. Whether you are experimenting with an arduino chassis or constructing a small rover, this design also acts as a stable 4wd car chassis for long-term use.
