[0002] In recent years, with the continuous improvement of communication technology, computer computing power, machine learning technology and image processing technology, autonomous mobile robots have gradually entered people's lives. It has brought great troubles to the autonomous walking of the robot. Now the commonly used robot movement methods are: electromagnetic induction, which allows the robot to move along a fixed path by laying tapes on the robot's running path; two-dimensional code assisted positioning, in the robot Paste the two-dimensional code on the path of the action. When the robot detects the two-dimensional code information through the visual detector, it will perform the corresponding action. However, these two control methods make the robot's movement path and degree of freedom very limited. , using laser radar to guide the robot's automatic operation can avoid the single trajectory of the robot's movement, but the outdoor environment is very limited. Currently, it is widely used indoors, and the robot's own hardware requirements are high, and the robot needs to compose the surrounding environment to achieve navigation. When encountering obstacles or deviations in the operation of the motor, errors in the positioning of the robot are often caused, and various obstacles are usually encountered during the walking operation of the self-mobile robot. Therefore, how to safely cross obstacles and ensure the robot's safety Motion accuracy and smooth walking are the key issues to improve the work efficiency of self-mobile robots
