Abstract
Provided are distance detection method and device for a cleaning robot, a cleaning robot, an electronic device and a non-transitory computer readable storage medium. The method includes: acquiring detection data of an obstacle detector of the cleaning robot, determining, according to the detection data, whether a distance between the cleaning robot and an obstacle reaches a first distance, where the first distance is a distance between the cleaning robot and the obstacle at a moment when a changing trend of the detection data fits a pre-set changing trend. In the embodiments of the present disclosure, whether the cleaning robot is moving to a specific position a certain distance away from the obstacle may be detected precisely. As the specific position is determined precisely, collision with obstacles can be avoided efficiently for the cleaning robot during working, and thus the distance detection method for the cleaning robot is improved.
