We are now facing labor crisis especially in logistics area because of the quickly shrinking population of working-age. Therefore, we must make logistics more efficient by utilizing robotics technologies. This paper proposes a method to plan local and global paths more effectively using hierarchized “maps”. By using this method, an autonomous mobile robot can plan its own local path using the information that cannot be observed just by itself. And more, the management platform of the autonomous mobile robots can prevent them from crashing or deadlocking each other, and can plan more efficient global paths as a whole.
