About this paper
Zain Alabedeen Ali, Konstantin Yakovlev
The paper introduces Prioritized SIPP-MAPFKC, an algorithm for Multi-Agent Path Finding that explicitly incorporates kinematic constraints like maximum speed and acceleration/deceleration directly into path generation. This approach generates kinematically feasible paths for multiple robots in warehouse-like environments, demonstrating that appropriate speed discretization balances computational time and solution cost while providing immediately executable paths.
Key insights
- Directly incorporating kinematic constraints into the SIPP framework produces paths that are immediately executable by physical robots, reducing or eliminating the need for post-processing.
- The choice of speed-step discretization significantly impacts algorithm performance, with an optimal 'medium step' balancing computational running time and solution path cost.
- Heuristic functions that explicitly account for speed discretization (e.g., H2) provide more effective guidance for the search algorithm in kinematically constrained scenarios.
