Outline

This paper presents Discrete-Guided Diffusion (DGD), a novel framework that integrates discrete multi-agent pathfinding (MAPF) and a constrained generative diffusion model to solve the multi-robot motion planning (MRMP) problem. DGD decomposes the nonconvex MRMP problem into tractable subproblems, combines discrete MAPF solutions with constraint optimization techniques to capture complex spatiotemporal dependencies, and incorporates a lightweight constraint recovery mechanism to ensure path feasibility. This approach demonstrates state-of-the-art performance, achieving planning efficiency and high success rates while scaling up to 100 robots in large, complex environments.

Takeaways, Limitations

Takeaways:
We present a novel approach that combines the advantages of discrete MAPF and continuous optimization techniques to simultaneously address the scalability of the MRMP problem and the path quality issue.
Demonstrates the possibility of efficient and high-success rate motion planning for large-scale multi-robot systems.
High-quality path generation considering complex spatiotemporal dependencies.
Limitations:
The performance of constraint recovery mechanisms may be affected by the complexity of the environment.
Lack of detailed analysis of the computational complexity of the proposed method.
Additional validation of generalization performance across various robot configurations and environmental conditions is needed.
