The application of mobile robot technology to agricultural machinery has become the main trend in the future development of agricultural machinery.Aiming at the positioning error and global path planning in the automatic harvesting process of the reed shoot harvester,based on the traditional A*search algorithm,it dynamically increases its field expansion range on the grid map to increase the smoothness of the planned path.The simulation results show that the improved A*algorithm makes the planned path smoother.This is mainly reflected in the average decrease in path length by 7.1%,average decr...
