Abstract

A robot cleaner, a system thereof, and a method for controlling the same. The robot cleaner system includes a robot cleaner that performs a cleaning operation while communicating wirelessly with an external device. The robot cleaner has a plurality of proximity switches arranged in a row on a lower portion of the cleaner body. A guiding plate is disposed in the floor of the work area, the guiding plate having metal lines formed in a predetermined pattern, the metal lines being detectible by the proximity switches. Since the recognition of the location and the determination of traveling trajectory of the cleaner within a work area becomes easier, performance of the robot cleaner is enhanced, while a burden of having to process algorithms is lessened.
