Path planning is one of the most important studied problems in the field of autonomous robots. The autonomous robot should pass around obstacles from a given starting position to a given target position, touching none of them, i.e. the goal is to find a collision-free path from the starting to the target position. Research on path planning has generated many fundamentally different approaches to the solution of this problem, in which A* algorithm is the one of the outstanding approaches have been developed for solving this problem, but it only ensures that the algorithm gives its result within a large amount of time-consumption. Therefore, in this paper, a Partitioning-Based Path Planning approach, called PBPP, has been proposed by partitioning-based and hierarchical methods that effectively improve the A* algorithm. The PBPP uses the concept of divide-and-conquer to divide the global map into each of sub-map in which a collision-free space is able to be represented. Furthermore, hierarchical planning can provide more feasible direction to achieve a smooth path in the result of the optimal path. The experimental results demonstrate the PBPP‘s utility for reducing time-consumption and finding low-cost paths.
