Compound Lifting Robot (RML-125-1800)

RealMan describes the “compound lifting robot” as an evolution of traditional “robot + AGV” combinations, adding a lifting system to expand workspace and improve task flexibility for operations that require both navigation and multi-height manipulation.

In RealMan’s naming, RML-125-1800 aligns with key lifting-rail parameters shown in official materials: a 125 mm rail width and an effective lifting height of 1.8 m.

Design and Features

Integrated “mobile base + lift + arm” architecture

RealMan’s compound lifting robot integrates five core subsystems through a master controller: mobile chassis, vertical rail, robotic arm, vision sensors, and an end effector.
This architecture is designed to support end-to-end workflows where the robot must move to a location, adjust working height, and manipulate objects—instead of relying on fixed-height arms or multiple stationary workcells.

Vertical lifting system for multi-height reach

Compared with a standard mobile manipulator, RealMan’s compound lifting robot adds a lifting mechanism to “further expand the robot’s workspace.”
For the RML-125-1800 configuration, RealMan lists 1.8 m effective lifting distance and a 150 mm/s lifting speed, enabling tasks across shelves, bins, carts, and workstation surfaces at different heights.

Sensor suite for mapping, navigation, and obstacle avoidance

RealMan describes the platform as equipped with multiple sensors—laser scanning, depth vision, and ultrasonic sensing—supporting scene mapping, path planning, and automatic obstacle avoidance based on perceived surroundings.
On the official specification page, safety and protection functions include laser scanning obstacle avoidance, visual obstacle avoidance, force sensors, and an emergency stop.

Open-source 3D vision sensor and task tooling

RealMan notes that the arm’s end is equipped with execution tools and an open-source 3D visual sensor, intended to improve accuracy and flexibility under a larger working space.
The system is positioned for “autonomous dynamic grasping” in structured scenarios such as logistics and “unmanned containers,” implying coordinated perception + grasp execution rather than simple scripted motions.

Lifting rail, arm, and sensors (brochure details)

In RealMan’s compound lifting robot brochure, the vertical rail is specified as: 24 V, 280 W rated power, 125 mm width, and 150 mm/s lifting speed.

The same brochure describes the integrated robotic arm module as a 6-DOF arm with 610 mm reach, 5 kg payload, ±0.05 mm repeatability, ~7.2 kg weight, and up to ~225°/s max joint speed (as presented in the parameter block).

For perception and navigation, the brochure references a sensor set including 10 m laser ranging radar (LiDAR), a depth camera, and ultrasonic distance sensors, supporting navigation and obstacle avoidance.

Navigation performance and mobility

RealMan lists ≤ ±5 cm positioning accuracy and shows a 1 m/s moving speed in the brochure table.
The chassis is described as an 8-wheel configuration (driving + mecanum + auxiliary wheels) with differential driving and active suspension, and it lists indicative endurance values such as ~20 hours standby and ~11 hours runtime at 0.7 m/s with no load.

Main control module (on-board compute)

RealMan’s official page lists a main controller module featuring an NVIDIA Volta GPU (384 cores, 48 Tensor Cores) and an NVIDIA Carmel ARM CPU, with 8 GB LPDDR4x memory and Ubuntu 18.04 as the operating system, plus multiple USB and GPIO-class interfaces.

Applications and Use Cases

Logistics warehousing and inventory workflows

RealMan positions the compound lifting robot for logistics warehousing use, where mobility, mapping, and multi-height manipulation can support tasks such as inventory checking, object handling, and station-to-station operations.
On the official page, example “Successful Cases” include Shelf Arrangement and Intelligent Warehouse Inventory, indicating typical warehouse-facing deployments (or demonstrations) for the platform.

New retail and structured indoor operations

RealMan lists New Retail as an application scenario for the compound lifting robot, consistent with store backrooms, micro-fulfillment, and structured indoor environments where a robot can navigate aisles and interact with shelves or bins at varying heights.

Unmanned containers and structured “trackless” navigation

In its brochure, RealMan describes support for path planning and trackless navigation in structured scenarios, referencing use in unmanned containers and operations requiring large-space autonomous movement and autonomous dynamic grasping.

Advantages / Benefits

Expanded workspace through lifting + manipulation

The defining benefit is the added lifting system, which increases vertical reach compared with a fixed-height mobile manipulator. RealMan explicitly states the lift expands the working space while improving accuracy and flexibility via vision and tooling at the arm end.

Integrated navigation and sensing for autonomous operation

RealMan’s materials emphasize an integrated perception stack (laser scanning, depth vision, ultrasonic) supporting mapping, planning, and obstacle avoidance—features that reduce the need for external navigation infrastructure in structured environments.

Development friendliness and multi-platform integration

The brochure notes developer support across API/library integration and environments such as Windows/Linux/ROS with multiple communication protocols, positioning the platform for research teams and integrators building custom workflows.

FAQ Section

What is the RealMan Robotics Compound Lifting Robot (RML-125-1800)?

It is a mobile manipulation robot that combines an autonomous chassis, a vertical lifting rail, a humanoid-style robotic arm, and 3D vision sensing to perform navigation and multi-height manipulation tasks in structured indoor environments.

How does the RML-125-1800 work?

RealMan describes it as integrating chassis + lift + arm + sensors under a master controller. The robot maps its environment, plans paths, avoids obstacles using LiDAR/depth/ultrasonic sensing, then lifts the arm along a vertical rail and executes grasping/manipulation using vision and end-effectors.

Why is the RML-125-1800 important?

Lifting mobile manipulators address a practical gap in warehouse and retail automation: many tasks require both mobility and vertical reach. RealMan positions the lift as a way to expand workspace and improve task flexibility compared with fixed-height mobile arms.
