Abstract
An embodiment of the invention provides a control method for a cleaning robot with a quasi-omnidirectional detector and a directional light detector. The method includes: rotating the non-omnidirectional light detector when the non-omnidirectional light detector detects a light beam; when the non-omnidirectional light detector does not detect the light beam, the non-omnidirectional light detector is stopped from being spun and a rotation angle is estimated; determining a rotation direction according to the rotation angle; rotating the cleaning robot according to the rotation direction; stopping the rotation of the cleaning robot when the directional light detector detects the light beam.
