Abstract:
A cleaning robot (50) and a cleaning control method and control device (40) thereof. The cleaning control method comprises: in response to a collision of the cleaning robot (50) and an obstacle (S11), controlling the cleaning robot (50) to rotate on the spot and using a distance sensor to scan the obstacle to obtain a mapping curve of scan data and rotation angles (S12); using the mapping curve to determine whether the size of the obstacle is less than or equal to a preset value (S13); and in response to that the size of the obstacle is less than or equal to the preset value, controlling the cleaning robot (50) to bypass the obstacle and then to continue moving along the original cleaning direction (S14). In response to that the size of an obstacle is less than or equal to a preset value, the cleaning robot (50) is controlled to bypass the obstacle and then to continue moving along the original cleaning direction, so that for an obstacle of which the size is less than or equal to the preset value, the cleaning robot (50) could bypass the obstacle and then continue moving along the original cleaning direction. Therefore, the cleaning robot (50) cleans the periphery of the obstacle without changing the original cleaning direction, improving cleaning coverage rate and cleaning efficiency and the cleaning capability to the periphery of an obstacle.
