The Wheeltec R5 Series Robot Mecanum Wheel Chassis is a heavy-duty, all-metal robot base platform engineered for serious robotics development. delivers smooth and stable maneuvering across carpet, concrete, and other indoor surfaces. Powered by two MD36L 60W DC gear motors paired with high-precision 500-line GMR encoders (or optional 13-line Hall encoders), the chassis achieves a top speed of 1.2 m/s with a maximum payload capacity of 15 kg. Pre-configured mounting points support NVIDIA Jetson Orin, Raspberry Pi, LiDAR sensors, and depth cameras — making the R5 a powerful foundation for ROS navigation, SLAM, and autonomous robotics research. Features High-Torque MD36L DC Gear Motors — Dual MD36L 60W brushed DC motors rated at 24V / 260 ± 12% RPM, delivering a rated torque of 10 kg·cm and a stall torque of ≥ 64 kg·cm for climbing and heavy-load capability. Dual Encoder Options — Choose the 500-line GMR encoder (high-precision, 3.3–5V, STM32-compatible) for demanding SLAM tasks, or the economical 13-line Hall encoder (3.3–5V, universal MCU compatible) for general-purpose development. Coaxial Swing-Arm Suspension — The universal caster uses a coaxial swing suspension system for consistent ground contact on uneven surfaces. Rich Peripheral Mounting Ecosystem — Pre-drilled mounting points for NVIDIA Jetson Orin, Raspberry Pi, LiDAR, depth cameras, IMU modules, displays, and microphone arrays. ROS 1 / ROS 2 Ready — Full ROS source code, assembly tutorials, and video guides included for rapid robotics development.
