Research on Path Planning of Mobile Robot based on A* Algorithm

Abstract

Path planning is one of the core issues in the field of intelligent robots, and it is also an important aspect in the study of artificial intelligence in robotics. The typical path planning problem refers to how to find the moving path from the starting point to the ending point for the robot in the working environment with obstacles, so that the robot can pass all obstacles safely and without collision during the movement. Firstly, the paper expounds the concept of mobile robot path planning and introduces the current research situation of mobile path planning. Then it introduces the steps of A* algorithm and A* algorithm implementation, and carries out MATLAB simulation experiment. The experiment proves that the A* algorithm can plan the global optimal path and ensure the fastness and accuracy of the path. It has certain reference significance for the future research of path planning.
