Abstract

The invention discloses a robot obstacle avoidance method, electronic equipment and a readable storage medium, which are applied to the technical field of artificial intelligence, and the robot obstacle avoidance method comprises the following steps: when a robot detects a dynamic obstacle, according to the original path planning information of the robot and the first motion feature information of the dynamic obstacle, determining the first motion feature information of the dynamic obstacle; predicting the collision probability of collision between the robot and the dynamic obstacle; when the collision probability is greater than a preset probability threshold, predicting second motion feature information of the dynamic obstacle in the next time step according to the first motion feature information; according to the original path planning information and the second motion feature information, the collision risk of the robot and the dynamic obstacle in the next time step is predicted, and a collision risk type label is obtained; and according to a path planning strategy corresponding to the collision risk type label, adjusting an original planning path corresponding to the original path planning information so as to control the robot to avoid the dynamic obstacle. The technical problem that the control safety of the robot is low is solved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to a robot obstacle avoidance method, electronic equipment and a readable storage medium. Background technique [0002] With the rapid development of science and technology, the application of robots is becoming more and more extensive. When the robot is working, it often encounters the risk of collision with obstacles. The distance between the obstacle and the robot is a method of avoiding obstacles, but the robot's travel information is not fixed, and the movement information of the obstacle is not constant, so that the distance between the obstacle and the robot determined only by the travel image Inaccurate, resulting in an increased risk of the robot colliding with obstacles, resulting in low control safety of the robot. Contents of the invention [0003] The main purpose of this application is to provide a robot obstacle avoidance method, electroni...
