4WD shock-absorbing chassis for off-road climbing ROS platform DIY

4WD Shock-Absorbing Smart Robot Chassis – Off-Road Climbing ROS Platform DIY

This 4WD shock-absorbing smart chassis is an ideal platform for off-road robotics, ROS learning, autonomous navigation, and terrain-testing experiments. It features independent suspension with metal shock absorbers that greatly improve stability on uneven surfaces such as rocks, gravel, or slopes.

The dual-layer mounting structure offers abundant space for controllers, batteries, sensors, cameras, LiDAR, IMU modules, and other expansion hardware. Its high-grip rubber tires and aluminum hub wheels provide excellent traction for climbing and obstacle traversal.

Compatible with popular robotics ecosystems like Arduino, Raspberry Pi, and ROS, this chassis is suitable for research, education, competitions, and advanced DIY builds. Designed for strength, stability, and modular customization.

Note: Controller and Batteries are not included and must be purchased separately.
