Abstract

The invention discloses a wall-following method of a cleaning robot, the cleaning robot comprises an infrared wall-following sensor, and the infrared wall-following sensor comprises an infrared transmitting tube, a main infrared receiving tube and an auxiliary infrared receiving tube. The wall-following method comprises the following steps: detecting an infrared signal received by an auxiliary infrared receiving tube; determining whether the infrared signal received by the auxiliary infrared receiving tube meets a strong and weak change condition or not; if the intensity change condition is met, the threshold value of the main infrared receiving tube is updated to the infrared signal currently detected by the main infrared receiving tube, so that the main infrared receiving tube guides the cleaning robot to perform edgewise operation according to the updated threshold value.

Description

technical field [0001] The present disclosure relates to the technical field of household appliances, and in particular, to a cleaning robot and a method for moving along a wall. Background technique [0002] A cleaning robot is an intelligent device that can assist users to clean the home environment, and it mainly includes a sweeping robot, a mopping robot, and a sweeping, suction and dragging integrated robot, etc. [0003] In order to enable the cleaning robot to effectively clean the corners of the wall and avoid the collision between the cleaning robot and the wall when the cleaning robot cleans along the wall, an existing cleaning robot is usually provided with a sensor along the wall. Existing sensors along the wall mainly include ToF ranging sensors, ultrasonic ranging sensors, and infrared-to-tube ranging sensors. Among them, infrared-to-tube ranging sensors are widely used in cleaning robots because of their low cost. [0004] However, the infrared-to-tube rangin...
