Revolutionizing Robot Collaboration in Unstructured Environments
This paper presents SPINE-HT, a framework addressing limitations in LLM-enabled heterogeneous robot teaming in unstructured environments. It grounds LLM reasoning in physical and semantic contexts through a three-stage process: generating validated subtasks, assigning them based on robot capabilities, and refining them with online feedback. SPINE-HT achieves nearly twice the success rate compared to prior LLM approaches in simulation and an 87% success rate in real-world missions involving diverse robot platforms like Jackals, Huskys, Spots, and UAVs.

Real-world Chemical Spill Triage Mission
Context: A team of heterogeneous robots (Husky, Spot, Jackal, UAV) is deployed to triage a chemical spill, locate a barrel, deliver a containment package, and block a road in an unknown, dynamic environment. The mission requires dynamic planning, capability-based tasking, and real-time adaptation.
Challenge: Traditional LLM planners struggle with grounding plans in the physical world, reasoning about robot-specific capabilities (e.g., Husky for rugged terrain, Spot for speed, Jackal for communication), and adapting to discoveries like a chemical barrel in an open-set environment.
Solution: SPINE-HT leverages LLM-generated, validated subtasks and assigns them based on robot capabilities. The UAV maps the area, Husky explores rugged terrain, Spot explores distant areas, and Jackal acts as a comms relay. Upon discovering a chemical barrel, SPINE-HT refines the plan, prioritizing its inspection and containment delivery by the Jackal.
Outcome: The mission was successfully executed with online adaptation, demonstrating robust heterogeneous collaboration and achieving an 87.5% success rate in real-world tests, significantly outperforming LLM-enabled baselines in unstructured settings.
Key Benefit
Reduced Hallucinations Through Plan Validation and GroundingThe framework significantly reduces LLM hallucinations and infeasible plans by employing an Assume-Guarantee framework for plan validation, ensuring subtasks respect robot capabilities and environmental constraints.
