A decentralized planner that guarantees the safety of communicating vehicles with complex dynamics that replan online
— This paper considers the problem of coordinating multiple vehicles with kinodynamic constraints that operate in the same partially-known environment. The vehicles are able to communicate within limited range. Their objective is to avoid collisions between them and with the obstacles, while the vehicles move towards their goals. An important issue of real-time planning for systems with bounded acceleration is that inevitable collision states must also be avoided. The focus of this paper is to guarantee safety despite the dynamic constraints with a decentralized motion planning technique that employs only local information. We propose a coordination framework that allows vehicles to generate and select compatible sets of valid trajectories and prove that this scheme guarantees collision-avoidance in the specified setup. The theoretical results have been also experimentally confirmed with a distributed simulator where each vehicle replans online with a samplingbased, kinodynamic mot...
