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 cleaner, and to control the positions accurately by installing a plurality of signal transmitting parts in several places to be cleaned and controlling the specific signal transmitting parts to transmit signals and to guide the robot cleaner. A station transmits signals of pre-set frequencies through signal transmitting parts. A robot cleaner receives the signals transmitted from the station through the signal receiving parts. The signal receiving parts judge whether the Doppler shift effect is observed(708). Directions to which the signal transmitting parts are placed are detected on the basis of the observed result of the Doppler shift effect(710). The signal receiving parts include antennas for receiving the signals from the signal transmitting parts. The antennas are moved along the rotation track of the robot cleaner.
