Customer Integration Case: Dual-Arm Mobile Manipulator Built on REEMAN Big Dog Chassis
A customer has developed a dual-arm mobile manipulator using the REEMAN Big Dog Mobile Chassis as its wheeled mobile platform.
The integrated system combines two robotic arms, custom grippers, and a mobile robot base to perform object handling and material transfer between workstations.
In the 82-second customer demonstration, the robot handles objects at a workstation, grasps a blue material bin using both arms, transports it to another workstation, places it down, and moves away.
This customer integration demonstrates how an existing REEMAN AMR chassis can serve as the mobility foundation for a customized dual-arm robotic system, reducing the need to develop the complete mobile platform from scratch.
Project Overview: From Mobile Chassis to Dual-Arm Robot
The customer integrated two robotic arms and application-specific end effectors onto the REEMAN Big Dog wheeled platform, creating a mobile manipulation system for object-handling operations.
Instead of developing a separate mobility platform, the project uses the existing chassis as the foundation for the customer's robotic arm integration.
Project Configuration
| Item | Project Details |
|---|---|
| Application | Dual-arm mobile manipulation |
| Mobile Platform | REEMAN Big Dog Mobile Chassis |
| Rated Chassis Payload | 100 kg |
| Robotic Arms | Two customer-integrated robotic arms |
| End Effectors | Customer-integrated grippers |
| Navigation | Laser SLAM |
| Obstacle Avoidance | LiDAR and 3D vision |
| Development Support | SDK and API interfaces |
| Demonstrated Workflow | Object handling, bin grasping, transport, and placement |
| Environment | Indoor demonstration area |
The robotic arms, grippers, and manipulation functions are part of the customer's integrated system. They are not standard components of the bare REEMAN chassis.
What Does the Dual-Arm Mobile Manipulator Demonstrate?
The customer video shows a sequence of robotic manipulation and material transfer operations, from initial object handling to placement at another workstation.
1. Object Handling at the First Workstation
The demonstration begins with an overview of the integrated dual-arm robot. The two robotic arms operate around a workstation and perform object-handling movements.
This sequence illustrates how robotic manipulation equipment can be combined with a mobile platform for customized workstation tasks.
2. Dual-Arm Grasping of a Material Bin
Both robotic arms approach a blue material bin. Their end effectors engage the bin, allowing the integrated system to lift it from the workstation.
This demonstrates the customer's integration of two robotic arms for handling a shared object.
3. Mobile Transportation Between Workstations
After grasping the material bin, the mobile robot travels toward another workstation while the robotic arms hold the load.
The wheeled platform provides the movement required to transfer the object between locations, combining mobile movement and manipulation within one integrated system.
4. Material Placement and Task Completion
At the second workstation, the robotic arms lower the material bin into position, release it, and retract.
The mobile platform subsequently moves away, completing the demonstrated handling and transfer sequence.
The central achievement of this customer project is the integration of dual-arm object manipulation with a wheeled mobile robot platform.

Why Use REEMAN Big Dog Mobile Chassis for Robotic Arm Integration?
Developing a mobile manipulator requires both robotic manipulation equipment and a suitable mobile platform.
For robotics developers, building the mobile platform independently also involves navigation, obstacle avoidance, motion control, communications, and charging functions.
The REEMAN Big Dog Mobile Chassis provides an existing autonomous mobile platform that developers can use as the basis for customized robotic applications.
100 kg Rated Payload for Equipment Integration
REEMAN Big Dog has a rated chassis payload capacity of 100 kg, supporting the integration of compatible equipment and robotic arm systems.
The total load must include robotic arms, mounting structures, controllers, grippers, and handled objects. Load distribution and dynamic stability must also be evaluated.
Laser SLAM Autonomous Navigation
The chassis uses Laser SLAM navigation for indoor mobile movement. It can navigate using environmental features without requiring magnetic strips or QR-code routes.
This provides developers with an existing navigation foundation for mobile robotic applications.
LiDAR and 3D Vision Obstacle Avoidance
The platform uses LiDAR and 3D cameras for navigation-related environmental perception and obstacle avoidance.
These sensing capabilities support mobile movement around obstacles. Application-specific object recognition and grasp planning are handled separately by the integrated manipulation system.
Open SDK and API for Secondary Development
REEMAN provides development interfaces for integrating supported chassis navigation and task functions into customized robot applications.
Depending on the applicable software configuration, available interfaces include:
- HTTP API: Navigation commands and supported status queries.
- Android SDK: Application integration and supported callbacks.
- RS232: Serial communication within the supported system architecture.
- Local MQTT: Compatible communication using REEMAN's Android-based AMR software.
Developers can integrate supported mobile navigation functions with their own robotic arm controllers and application software. The available commands and status data depend on the selected interface.
What Makes Big Dog Suitable for Customized Robot Development?
The value of a ready-made mobile chassis is its ability to provide the mobility foundation for different robotic development projects.
Potential integration applications include:
- Single-arm mobile manipulators
- Dual-arm mobile manipulation systems
- Warehouse picking robots
- Mobile inspection equipment
- Research and laboratory robotic platforms
- Customized industrial mobile robots
This customer's dual-arm project is an example of how a wheeled chassis can be incorporated into a customized robotic system.
The suitability of each proposed application depends on its mechanical, electrical, software, and safety requirements.
What Should Developers Evaluate Before Robotic Arm Integration?
Before choosing a chassis for a single-arm or dual-arm mobile manipulator, developers should assess the complete system requirements.
| Requirement | What to Evaluate |
|---|---|
| Payload | Total installed weight and maximum handled object load |
| Mechanical Stability | Arm reach, center of gravity, and dynamic forces |
| Mounting | Installation dimensions, structural rigidity, and mounting points |
| Navigation | Operating environment, pathways, and obstacles |
| Software Integration | Required SDK/API commands and control interfaces |
| Power | Robotic arm and controller power requirements |
| Safety | Combined mobile base and robotic arm operating conditions |
A chassis rated for 100 kg does not automatically guarantee compatibility with every robotic arm combination. Engineering assessment is required to verify stability and integration feasibility.
