Abstract
A robot cleaner includes a drive unit for driving a plurality of wheels, a camera disposed in a body for photographing an upper image extending perpendicular to a running direction, a controller for recognizing a position by using position information obtained from a recognition mark formed on a ceiling of a working area that is photographed by the camera, and controlling the drive unit by using the recognized position information to correspond to a target cleaning operation. Accordingly, since the recognition mark for the recognition of a current position of the robot cleaner is formed on a ceiling that has a few changes, the position recognition is performed with more accuracy and the traveling of the robot cleaner to the target work area and a cleaning operation is performed efficiently.
