Intelligent warehousing and intelligent factory are important development directions in the future,in which automated guided transport vehicles(AGVs)/mobile robots play an important role.Path planning is one of the core technologies for AGV/mo-bile robots,which has been widely studied.A* algorithm has attracted much attention because of its unique advantages in global path planning.In view of its problems such as redundant points and unsmooth path,researchers have made a lot of improvements and optimization researches on A* algorithm.This paper mainly summarizes the research progress in recent years mainly from two aspects of optimizing the evaluation function of A* algorithm and the fusion of A* algorithm with other algorithms.Based on the current research progress and trend,some suggestions are put forward for the future research.
