Mobile robot path planning method based on distance judgment and angle deflection

The invention provides a mobile robot path planning method based on distance judgment and angle deflection. The method comprises the following steps: step 1, a global grid map constructed by using anSLAM mapping algorithm is taken as priori information, global path planning is performed to obtain a pre-planned path, and if the environment of the static environment is not changed, a mobile robot moves according to the pre-planned path; and step 2, when the environment is changed, i.e., an obstacle appears on the pre-planned path, the mobile robot acquires distance information and obstacle angle range information according to information scanned by laser radar, and is guided to deflect and move, so that the purpose of returning to the global pre-planned path is achieved, and the navigationof the robot in a dynamic environment is further realized. According to the method, obstacle distance information and angle range information are obtained through an existing sensor of the robot, triangle solving is conducted to calculate an obstacle avoidance track, the calculated amount of the robot is reduced, the real-time performance of robot movement is enhanced, and the moving efficiency ofthe robot is improved.
