改进A*与DWA的交通隔离机器人路径规划研究
Traffic isolation robot path planning based on improved A* and dynamic window approach
摘要
Abstract
In view of the prolonged search time and excessive hazardous points in paths when applying the traditional A*algorithm to traffic isolation robots,this study proposes a hybrid algorithm integrating improved A* with the dynamic window approach(DWA).Firstly,a four-neighborhood combined with left-right symmetric convex neighborhood search strategy is employed,along with an angular search strategy and the obstacle-distance-map weighting strategy(ODMW),to optimize redundant nodes in global paths.A bidirectional A* scheme is introduced to enhance search efficiency.Subsequently,the enhanced A* global path planning algorithm is integrated with DWA to improve real-time obstacle avoidance capabilities.Finally,simulations and physical experiments were conducted to evaluate the performance of the improved algorithm.The results demonstrate that the optimized A* algorithm significantly reduces hazardous points along paths,decreases average search time by 68.22%,and reduces average expanded nodes by 55.76%.Moreover,the hybrid algorithm combining improved A* with DWA enables traffic isolation robots to accurately reach targets while effectively avoiding unknown obstacles.关键词
