DD-GBP: Anytime Multi-Arm Planning and Continuous Execution via Distributed Dynamic Gaussian Belief Propagation

We propose a new distributed dynamic Gaussian belief propagation (DD-GBP) method that directly plans joint-space trajectories through parallel local inference.

Key points

  • Safely executing long-horizon multi-arm tasks online in complex dynamic environments remains challenging.
  • A unified Gaussian-process (GP) parameterization connects adaptive planning horizons, interpolation-time factors, and continuous execution.
  • Dynamic subnet reconstruction and event-triggered updates reduce communication and inference costs while responding to moving obstacles.
  • In 50 long-horizon, multi-target four-arm scenes with moving obstacles, DD-GBP achieves $92.5%$ collision-free all-target completion and the highest success rate among six representative baselines.
