Diffusion for Long-Horizon Multi-Robot Path Planning in Human-Shared Environments

Jul 14, 2026

Researchers introduce Multi-Robot Rolling Diffusion (MRRD), a framework designed for real-time, long-horizon navigation of robot teams in crowded human environments. MRRD integrates rolling-horizon planning, parallelized diffusion inference, and conflict-based search to generate socially aware, human-like paths while resolving inter-robot collisions. Experiments demonstrate that MRRD scales to 15 robots in real-time and significantly outperforms existing baselines in both safety and mission success rates.

Why it matters: This work represents a notable advance in multi-robot coordination for crowded, human-shared spaces, supporting safer and more efficient deployment of robot teams in real-world environments.
