Problems solved by technology

If the predetermined distance in the obstacle avoidance path is too large, there will be too many missed scanning areas; if the predetermined distance is too small or some obstacles may be damaged after colliding with obstacles, in some cases, it is also easy for the cleaning robot to be trapped

Abstract

The invention provides an obstacle processing method and a cleaning robot. The cleaning robot comprises a controller, an image acquisition device, a robot body and a side sweeper, and the side sweeperextends to exceed the edge of the robot body. The image acquisition device is used for acquiring a first image of an obstacle in the advancing direction of the cleaning robot. The controller is usedfor identifying the type of the obstacle according to the first image of the obstacle; determining an obstacle processing mode corresponding to the type of the obstacle, the obstacle processing mode including whether the cleaning robot continues to advance according to the advancing direction before the obstacle, and distance information between the robot body and the obstacle and distance information between the side sweeper and the obstacle when the cleaning robot changes the advancing direction before the obstacle. The controller is used for controlling the cleaning robot to move accordingto an obstacle processing mode corresponding to the type of the obstacle. By implementing the method, the sweeping coverage rate can be increased for different obstacles, and meanwhile, the sweeping risk is reduced.

Description

technical field [0001] The present application relates to the field of intelligent robots, in particular to an obstacle handling method and a cleaning robot. Background technique [0002] In modern life, cleaning robots are gradually applied and popularized. During the cleaning process of the cleaning robot, various obstacles will be encountered, such as walls, tables and chairs, vases, etc. The existing obstacle handling scheme is mainly to install non-contact sensors on the front or top of the cleaning robot, such as infrared, laser or ultrasonic ranging sensors, to detect distant obstacles in a non-contact manner; then install a Set of contact sensors, such as switches or capacitive sensors, to detect the contact between the cleaning robot and obstacles. The non-contact sensor cooperates with the contact sensor to form a set of obstacle avoidance paths. In the prior art, during the cleaning process, the cleaning robot changes its motion path within a predetermined dist...
