Path Planning for Multi-robot Systems in Intelligent Warehouse

In this work, the path planning problem of robotics group is surveyed in the context of multi-robot transportation tasks on an intelligent warehouse. The mainly researches focused on the a shortest path theory and algorithm for single robot system. To solve the path planning problem on multi-robot systems, a novel approach is presented for multi-robot systems in an intelligent warehouse by using the method of artificial potential function (APF) in this paper. The proposed improving method of APF that motioned the strategy of wall-following with priority and how to solve the unavoidable troubles in obstacle avoidance for multi-robot systems such as local minima, non-reachable target, collision and traffic jams. Finally, several numerical simulations were provided to show the effectiveness, and the performance of the proposed method with the theoretical results.
