At a Glance
A three-layer system ties language-driven planning to real robot control using a digital twin and standardized tool interfaces, letting heterogeneous robots coordinate safely and reducing manual hardware testing from days to hours.

Key Findings
A semantic layer (language and vision models) plans tasks at a low rate while a separate physical layer handles fast control; an online tool pool maps abstract instructions into runnable software calls so different robot platforms can share the same plans. A digital twin using extended robot descriptions checks collisions and dynamics before commands reach hardware, preventing infeasible or unsafe actions. Execution traces and observations are stored in a local resource pool so the system can reuse skills and gradually align high-level reasoning with real-world capabilities.

Data Highlights
1Validated in a 60 m² smart-home testbed with kitchen and living room scenes.
2Demonstrated coordination across up to four heterogeneous robots; main physical demo involved three collaborating robots operating across three constrained regions.
3Authors report cutting manual annotation and demonstration effort from days to hours by using the data collection and reuse loop.
What This Means
Robotics engineers and system integrators who need one framework to orchestrate diverse robot types without hand-tuning every SDK will find this useful. Technical leads evaluating multi-robot deployments can use the tool-pool + digital twin pattern to reduce risky hardware tests and speed integration. Researchers building embodied agents can reuse the local data pool to bootstrap physically grounded training data. Human-in-the-Loop Pattern
Key Figures
Fig 1: Figure 1: The ROSClaw framework adopts a three-layer semantic–physical architecture to bridge high-level cognitive reasoning and low-level physical control. The cognitive layer relies on LLM knowledge graphs and logical elements in the digital space to support macro-level task understanding. The coordination automation layer abstracts hardware heterogeneity through an Online Tool Pool and enables task environment activation. The ROSClaw physical world provides unified control over heterogeneous robotic agents while continuously accumulating multimodal observations, robot states, and reusable skills within a Local Resource Pool. The accumulated interaction experience is fed back to the cognitive layer, forming a closed-loop process that supports continual system evolution and cross-task knowledge reuse.
Fig 2: Figure 2: e-URDF-based physical firewall. Heterogeneous system resources (SDKs, MCPs, and APIs) are aggregated into an Online Tool Pool to enable the transformation of abstract instructions into executable operations. A strict e-URDF-based physical safeguarding mechanism for heterogeneous agents is adopted, leveraging forward dynamics simulation and collision detection in Isaac Lab to ensure physical feasibility prior to scheduling.
Fig 3: Figure 3: Real-World Environment for Collaborative Tasks. In the physical environment, S 1 S_{1} denotes the mobile manipulation region, S 2 S_{2} represents the localized grasping region, and S 3 S_{3} corresponds to the mobile navigation region. Each embodied agent in the physical world is constrained to operate only within a subset of these regions.
Fig 4: Figure 4: Heterogeneous Multi-Agent Collaboration. In (A), ROSClaw receives user requirements, initializes the sub-agents, assigns tasks to each agent, and simultaneously exchanges state information with them. In (B), the log outputs generated during task execution by each sub-agent are presented. In (C), the physical-world execution is illustrated: the mobile robotic arm approaches the doorway and opens the door; the humanoid robot enters and moves toward the harvesting area; the fixed robotic arm transfers the fruit; and the humanoid robot carries the fruit basket to the kitchen.

Evaluations were in structured or semi-dynamic indoor settings; performance under heavy clutter, rapid disturbances, or very noisy perception is not yet shown. The local resource pool collects data but does not yet close the loop into fully autonomous policy optimization—further work is needed to turn logs into continual learning. Scaling to many more robots, more unpredictable environments, or fully decentralized trust/evaluation mechanisms will require additional engineering and probabilistic modeling. State Inconsistency
The Details
ROSClaw is a system-level framework that bridges the gap between high-level, language-driven planning and low-level robot control for heterogeneous teams. It uses a three-layer design: a cognitive layer with language and vision models for low-rate, long-horizon planning; a coordination layer that exposes an Online Tool Pool to translate abstract instructions into platform-specific software calls; and a physical layer that runs robots while enforcing safety and feasibility. The system separates slow semantic planning from fast control so planners need not be tightly coupled to hardware timing, and it validates candidate actions in a headless digital twin before they reach real actuators. The digital twin uses an extended robot description format to run collision checks and forward-dynamics checks, acting as a physical firewall to filter infeasible commands.
