针对障碍环境中的多机器人无碰撞路径规划,提出围绕虚拟智能体的编队势场准集中式方法,兼顾编队维持与局部避障,并验证五边形编队可安全通过狭窄通道。

摘要:

本文提出了一种新颖的准集中式方法,用于多机器人系统(MRS)在充满障碍物环境中的无碰撞路径规划。围绕位于编队中心的虚拟智能体,提出了一种新的编队势场(FPF)概念,可确保编队的自组织与维持。虚拟智能体的路径采用集中方式规划,而处于FPF极小值处的机器人被迫随虚拟智能体一起移动。在障碍物附近,各个机器人自私地规避碰撞,因此会略微偏离编队。所提出的准集中式方法为MRS引入了编队灵活性,使其能够在充满障碍物的工作空间中有效导航。文中给出了对该方法的系统分析以及选择FPF的指导原则。使用一种候选FPF的结果表明,其可确保五边形编队有效挤过狭窄通道,并避免与墙壁发生任何碰撞。

英文摘要:

This paper presents a novel quasi-centralized approach for collision-free path planning of multi-robot systems (MRS) in obstacle-ridden environments. A new formation potential fields (FPF) concept is proposed around a virtual agent, located at the center of the formation which ensures self-organization and maintenance of the formation. The path of the virtual agent is centrally planned and the robots at the minima of the FPF are forced to move along with the virtual agent. In the neighborhood of obstacles, individual robots selfishly avoid collisions, thus marginally deviating from the formation. The proposed quasi-centralized approach introduces formation flexibility into the MRS, which enables MRS to effectively navigate in an obstacle-ridden workspace. Methodical analysis of the proposed approach and guidelines for selecting the FPF are presented. Results using a candidate FPF are shown that ensure a pentagonal formation effectively squeezes through a narrow passage avoiding any collisions with the walls.
