The Realman Robotics RML-125-1800 is a compound lifting robot that unites five core subsystems — a mobile chassis, a vertical lifting rail, a 6-DOF robotic arm, vision sensors, and an end effector — under a single master controller. The model designation reflects its lifting hardware: a 125 mm rail width and an effective lifting height of 1.8 m, travelled at 150 mm/s. Where a conventional mobile manipulator is limited to one working height, the RML-125-1800 drives to a location, adjusts its arm elevation, and manipulates objects across shelves, bins, carts, and workstation surfaces. The integrated arm module offers 610 mm reach, 5 kg payload, and ±0.05 mm repeatability, while an open-source 3D visual sensor at the arm end supports autonomous dynamic grasping rather than simple scripted motion.

Realman positions the platform for logistics warehousing workflows such as inventory checking, object handling, and station-to-station operations, including structured scenarios like unmanned containers. Navigation combines a 10 m laser ranging LiDAR, a depth camera, and ultrasonic sensors for scene mapping, path planning, and automatic obstacle avoidance, delivering positioning accuracy of within about ±5 cm at travel speeds up to 1 m/s. The eight-wheel chassis pairs differential drive with active suspension and lists roughly 11 hours of runtime at 0.7 m/s unloaded and around 20 hours on standby. Onboard computing is handled by an NVIDIA Volta GPU (384 cores, 48 Tensor Cores) and NVIDIA Carmel ARM CPU running Ubuntu 18.04, and safety functions include laser and visual obstacle avoidance, force sensors, and an emergency stop.
