The path planning of agricultural robot can improve the working efficiency of the robot,optimize the working path,save energy consumption,reduce operating costs,and improve the quality and accuracy of operation,which has become an important direction of agricultural robot research.With the promotion of market and national policy,agricultural robot path planning has been developed rapidly in China.The key of path planning technology is to obtain accurate environmental information,map construction,and the choice of intelligent planning algorithm.In this paper,the key points of agricultural robot path planning technology are sorted out and summarized.The requirements and differences of path planning in different agricultural scenes were described,the methods and characteristics of path planning were analyzed,and the commonly used path planning algorithms and their characteristics were introduced,including A*algorithm,Dijkstra algorithm,particle swarm optimization algorithm,RRT algorithm and so on.Finally,the development trend of agricultural robot path planning was analyzed and prospected.
