ABSTRACT:
A robot cleaner, a robot cleaning system and a method for controlling the same capable of efficiently performing work on command by recognizing the driving distance and direction of the robot cleaner regardless of a of wheel slippage or irregularity in the floor. The robot cleaner performs a working operation while moving about a floor, and comprises a main body, a driving unit for driving a plurality of wheels disposed on a bottom portion of the main body, a downward-looking camera disposed among the wheels on the bottom portion of the main body for photographing images of the floor perpendicular to the driving direction of the robot cleaner, and a control unit for recognizing driving distance and direction of the wheels using image information of the floor photographed by the downward-looking camera, and for controlling the driving unit corresponding to a target work by using the recognized distance and direction of the wheels. An upward-looking camera can photograph and use information relating to spatial orientation for determining and correcting driving distance and direction.
