A robot cleaner, a robot cleaning system and a method for controlling the same that is capable of independently determining whether a cleaning work in a work area is completed. This is accomplished by providing a robot cleaner for performing cleaning work by communicating wirelessly with an apparatus external to the robot cleaner, comprising a main body provided with a suction unit for collecting dust on a floor to be cleaned, a driving unit disposed on the main body for driving a plurality of wheels, an upward-looking camera disposed on a top of the main body for photographing images of a ceiling perpendicular to a direction of driving the robot cleaner, an obstacle detection sensor disposed on a front of the main body for detecting an obstacle positioned ahead of the robot cleaner in the driving direction, a memory for storing position information of the obstacles detected by the obstacle detection sensor; and a control unit for calculating position information of the obstacle to store the calculated obstacle position information in the memory upon receiving an obstacle detection signal from the obstacle detection sensor, determining whether the obstacle position information stored at the memory forms a closed curve, and further controlling the driving unit to drive the robot cleaner along a predetermined driving pattern, wherein the control unit stops the suction unit from operating when the obstacle position information forms a closed curve. |
