Large 2-Layer Aluminum 4WD Robot Chassis for Arduino & Raspberry Pi

Professional robotics projects demand more than just a place to mount components – they need a foundation that can grow with your ambitions. The YonPhsy 2-Layer 4WD Robot Chassis Kit delivers exactly that. At the heart of this kit is a rugged two-tier aluminum alloy frame. The dual-layer design does more than look impressive – it separates your electrical system from your mechanical system, giving you dedicated space for main control boards and sensors on the upper deck while housing batteries, motor drivers, and power distribution on the lower level. No more tangled wires, no more struggling to fit everything onto a cramped single plate. Four TT gear motors with a 1:48 reduction ratio power the 4WD system, delivering reliable torque and smooth movement across both indoor lab benches and outdoor test tracks. The large rubber-tread wheels provide excellent grip and shock absorption, while the 4WD configuration ensures balanced power distribution even when carrying heavy payloads like camera modules, LiDAR units, or full sensor suites. The spacious 230×168mm platform offers nearly 40% more mounting area than standard single-layer chassis, with abundant pre-drilled holes for attaching ultrasonic sensors, IR modules, servo brackets, and virtually any accessory compatible with Arduino, Raspberry Pi, and other popular development boards. The 480g all-aluminum build provides the structural rigidity needed for advanced applications – from ROS-based autonomous navigation to AI-powered obstacle avoidance. Everything you need comes in the box: two precision-cut aluminum plates, four TT motors, four rubber wheels, motor fixing blocks, all necessary hardware, connecting wires, and even a screwdriver for assembly. Whether you are an engineering student building your first autonomous rover, a researcher prototyping the next generation of mobile robotics, or a competitor preparing for a robotics championship, this chassis kit provides the professional-grade foundation your project deserves
