How Can a Wheeled Robot Chassis Support Dual-Arm Mobile Manipulation?
A wheeled autonomous mobile robot (AMR) chassis provides the mobility foundation for mobile manipulators, allowing robotic arms to perform handling operations at different workstations.
A customer-developed dual-arm mobile manipulator built on the REEMAN Big Dog Chassis demonstrates this approach. In the 82-second video, the integrated robot performs object-handling operations, grasps a blue material bin with two robotic arms, transports it to another workstation, and places it down.
The REEMAN Big Dog Robot Chassis offers a 100 kg rated payload capacity, Laser SLAM navigation, LiDAR, dual 3D cameras for obstacle avoidance, and open SDK/API interfaces for customized robot development.
This case demonstrates how robot developers can use an existing wheeled AMR platform as the foundation for a dual-arm manipulation system instead of developing the entire mobility system from scratch.
Why Use a Wheeled Robot Chassis for Dual-Arm Mobile Manipulation?
A fixed robotic arm can only reach objects within its working area. Combining robotic arms with a wheeled mobile base allows developers to design systems that move between workstations and handle objects at multiple locations.
For indoor factories, warehouses, and laboratories, wheeled AMR platforms offer several advantages:
- Efficient indoor mobility: Suitable for smooth factory and warehouse floors.
- Autonomous navigation: Reduces the need to develop a mobile navigation system from scratch.
- Flexible integration: Supports customized robotic arms, grippers, controllers, and equipment.
- Open development interfaces: Enables navigation and task-related integration with external systems.
- Modular architecture: Allows developers to focus on manipulation functions and application workflows.
For operations on relatively flat indoor surfaces, wheeled platforms often provide a practical balance of mobility efficiency, integration complexity, and operating cost.
However, chassis suitability must be evaluated based on total system weight, center of gravity, arm reach, and dynamic loads.
Customer Integration Case: Dual-Arm Mobile Manipulator Built on REEMAN Big Dog
This customer-developed system integrates two robotic arms and custom end effectors with the REEMAN Big Dog wheeled AMR chassis.
The video documents a sequence of robotic manipulation and material transfer operations in an indoor demonstration environment.
1. Dual-Arm Object Handling
The video first shows the dual-arm mobile manipulator and its integrated robotic structure.
The robotic arms then operate around a workstation, interacting with objects and demonstrating manipulation movements.
This illustrates how robotic arms can be combined with a mobile platform to perform customized workstation tasks.
2. Dual-Arm Grasping of a Material Bin
The two robotic arms approach a blue material bin.
Their end effectors engage the bin, allowing the integrated system to lift it from the workstation.
This sequence demonstrates two-arm object handling within the customer's customized robotic system.
3. Mobile Transport and Bin Placement
After grasping the bin, the mobile robot moves toward another workstation while carrying the object.
The robotic arms lower the bin into position, release it, and retract.
The mobile platform subsequently moves away from the workstation.
The key value of this demonstration is the integration of wheeled mobility with dual-arm object manipulation in one robotic system.
The video represents a customer integration demonstration, not verified evidence of production deployment, handling throughput, or long-term operating performance.

What Does REEMAN Big Dog Chassis Provide for Robot Developers?
The REEMAN Big Dog Robot Chassis is a wheeled AMR platform designed to support customized robotic applications.
It combines autonomous mobility, navigation, environmental perception, and development interfaces in a single platform.
REEMAN Big Dog Chassis Specifications
| Specification | REEMAN Big Dog Chassis |
|---|---|
| Platform type | Wheeled AMR chassis |
| Rated payload | 100 kg |
| Navigation | Laser SLAM |
| Navigation sensor | LiDAR |
| Vision sensing | Dual 3D cameras |
| Obstacle avoidance | LiDAR and 3D vision |
| Development interfaces | HTTP API, Android SDK, RS232, local MQTT |
| Navigation control | Waypoint and coordinate-based commands |
| Charging | Automatic docking and recharging |
| Network deployment | Private LAN supported |
| Offline operation | Preconfigured local tasks supported |
| Elevator integration | Optional, subject to system configuration |
Engineering note: The 100 kg payload capacity applies to the entire load carried by the chassis. This includes robotic arms, mounting structures, controllers, additional equipment, and handled objects.
It is not the lifting capacity of each robotic arm. The stability of a dual-arm installation must be evaluated separately.
How Does REEMAN's Open SDK Support Secondary Development?
For robot manufacturers and system integrators, software integration is an important factor when selecting an AMR chassis.
REEMAN provides several interfaces to support customized robotic applications.
HTTP API
Supports navigation commands, task control, and available robot status queries.
Android SDK
Provides application integration functions and supported callbacks.
RS232 Serial Communication
Supports serial communication within the applicable system architecture.
Local MQTT
Supports compatible local communication when using REEMAN's Android-based AMR software.
Through supported interfaces, developers can command the mobile platform to navigate to predefined coordinates or waypoints, pause or cancel tasks, and return to its charging station.
Robotic arm movement, grasp planning, and application-specific object recognition are integrated separately.
The standard chassis SDK does not provide raw navigation-camera streams for customized AI object recognition. Developers may require an additional vision system for robotic grasping applications.
How to Choose a Wheeled Chassis for a Dual-Arm Mobile Robot
Before purchasing an AMR chassis for robotic arm development, evaluate these five requirements.
1. Total Payload
Calculate the combined weight of robotic arms, mounting equipment, controllers, end effectors, and handled objects.
2. Mechanical Stability
Evaluate center of gravity, arm extension, load distribution, and dynamic forces during movement and object handling.
3. Navigation and Sensing
Check whether the chassis supports autonomous navigation and obstacle avoidance appropriate for the intended operating environment.
4. SDK/API Integration
Confirm the availability of navigation commands, robot status information, and required communication protocols.
5. Application Workflow
Evaluate workstation positioning, floor conditions, charging, safety requirements, and system-level coordination.
For projects requiring a wheeled AMR platform with 100 kg rated payload capacity, Laser SLAM navigation, 3D vision obstacle avoidance, and development interfaces, REEMAN Big Dog is a candidate for integration evaluation.
