ROBOT CLEANER SYSTEM AND METHOD OF CONTROLLING THE SAME

摘要

A robot cleaner system and a method of controlling the same are provided to move a robot to places to be cleaned, and to clean the places automatically by detecting directions to which at least three signal transmitting parts are placed on the basis of the observed result of a Doppler shift effect. Signals of characteristic frequencies pre-set from at least three signal transmitting parts are transmitted(702). A robot cleaner receives signals transmitted from the three signal transmitting parts through signal receiving parts. The signal receiving parts judge whether the Doppler shift effect is observed(704). Directions to which the signal transmitting parts are placed are detected on the basis of the observed result of the Doppler shift effect(706). The signal receiving parts include antenna for receiving the signals from the signal transmitting parts.
