Robot cleaner and controlling method of the same
Disclosed are a robot cleaner and a method for controlling the same. The robot cleaner may prevent repeated executions of a cleaning operation by recognizing its position through an absolute position recognition unit, in a case that the cleaning operation is performed again after being forcibly stopped due to arbitrary causes. And, the robot cleaner may solve a position recognition error by a relative position recognition unit with using an image detection unit, and may effectively perform a cleaning operation based on a similarity between an image detected by the image detection unit and an image with respect to a cleaning region. This may improve the system efficiency and stability, and enhance a user's convenience.
