A robot cleaner, robot cleaning system, and a method for controlling the same, the robot cleaner cleaning by wirelessly communicating with an external apparatus having a driving unit for driving a plurality of wheels; an upper camera disposed on a main body for photographing an upper image perpendicular to a direction of driving the robot cleaner; and a controller for controlling the driving unit to allow the robot cleaner to drive with a cleaning area according to a predetermined driving pattern, and compensating the driving path by analyzing the image photographed by the upper camera. In other embodiments, the robot cleaner may include a second forwardly directed camera which may be utilized to provide a three dimensional image of the cleaning area, and also sensors for sensing the walls defining a cleaning area or obstacles in the cleaning area. In yet another embodiment, and to reduce the image computing load on the robot cleaner, transmission of the image to an external processor/controller may be effected by a radio antenna. The robot cleaner, the robot cleaning system, and the method for controlling the same, can recognize the robot cleaner position more accurately as the position is recognized by using an upper image that does not experience as much alteration as does a floor. Therefore, a movement error to a target position is reduced, and a commanded work can be performed more easily.
