Abstract
A self-driving vacuum cleaner may include: a main body; a drive unit; a pattern irradiation unit, disposed on a front surface of the main body, for irradiating light; a camera, disposed on the front surface of the main body; and a controller for detecting a light pattern formed by the pattern irradiation unit using an image photographed by the camera, determining whether an obstacle exists in front of the main body on the basis of the brightness of the detected light pattern, and controlling the drive unit to pass or avoid the obstacle on the basis of the determination result.
