Aiming at the problem of path conflicts among multiple robots running in the same environment during mobile robot cluster operations, which can lead to collisions among robots, this paper studies a trajectory planning algorithm for mobile robot clusters that integrates graph neural networks. Construct a kinematic model of a mobile robot to describe its motion characteristics; Using a fusion graph neural network-based mobile robot cluster operating environment feature extraction model, multi-dimensional features of the mobile robot cluster operating environment are extracted to comprehensively understand environmental information; Combining the artificial potential field method, based on the extracted features, the destination is set as a gravitational source, and the direction of motion that attracts the robot is towards the destination; Set obstacles as repulsive sources, control robots to avoid obstacles, and determine the direction and speed of each robot's movement based on the resultant force. Plan collision avoidance trajectories for mobile robot clusters during operation. The experiment shows that the proposed algorithm can effectively extract multidimensional features of the operating environment of mobile robot clusters, and plan collision free and risk index less than 0.1 running trajectories for multiple mobile robots.
褚晶等[7]构建 Petri 网模型描述多机器人运动状态与行为,用线性时序逻辑(LTL)语言精确表述月球基地建设等任务的逻辑和时序要求,结合二者协同运算分析,求解多机器人路径规划结果。而在一些需要机器人进行灵活决策和自适应调整的任务中,LTL 语言的精确性和固定的逻辑结构可能无法充分涵盖所有情况,导致任务描述不完整,进而影响路径规划的准确性。
