Robot cleaner, robot cleaning system and method of controlling same
First Claim
1. A robot cleaner for performing a cleaning operation comprising:
- a drive unit for driving a plurality of wheels;
a camera disposed in the body; and
a controller programmed to recognize a position of the drive unit using position information obtained from a recognition mark 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,wherein the recognition mark has a plurality of direction indicating portions integrally formed therewith, the direction indicating portions formed in an azimuthal direction from a predetermined center point of the recognition mark and having different lengths.

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.

3. A robot cleaning system comprising:
-
a robot cleaner comprising a drive unit for driving a plurality of wheels; an upper camera disposed in the body, for photographing an upper image extending perpendicular to a running direction of the robot cleaner; and a remote controller in wireless communication with the robot cleaner programmed to recognize a current position of the robot cleaner by using an image of a recognition mark formed on a ceiling of a working area that is photographed by the upper camera, and controlling a working course of the robot cleaner to perform a target cleaning operation based on a recognized current position of the robot cleaner, wherein the recognition mark has a plurality of direction indicating portions integrally formed therewith, the direction indicating portions formed in an azimuthal direction from a predetermined center point of the recognition mark and lengths that are different from one another. - View Dependent Claims (4, 5, 6, 7)

8. A robot cleaner comprising, in combination:
-
a body; a suction unit; a plurality of wheels; a drive unit connected to the wheels; an obstacle detecting sensor positioned on the body; a running distance detecting sensor positioned on the body; a camera configured to photograph a recognition mark formed on a ceiling of an area to be cleaned; a controller configured to send a signal to the drive unit and programmed to recognize a position of the robot cleaner based on a comparison of a current photograph of the recognition mark and a stored photograph of the recognition mark, wherein the recognition mark has a plurality of direction indicating portions integrally formed therewith, the direction indicating portions formed in an azimuthal direction from a predetermined center point of the recognition mark and having different lengths. - View Dependent Claims (9, 10)
