ROBOT CLEANER SYSTEM AND METHOD FOR CONTROLLING A ROBOT CLEANER
First Claim
1. A method of controlling a robot cleaner, comprising:
- a calculation step of, when cleaning start information is received, a control unit of the robot cleaner scanning one cleaning area including a plurality of small regions by driving a driving unit of the robot cleaner, thus calculating a cleaning time for the cleaning area;
a cleaning step of the control unit performing cleaning of the cleaning area by driving the robot cleaner;
a detection step of, when a signal transmitted from a transmission device located in the cleaning area is received during performance of cleaning, the control unit detecting which transmitter, among a plurality of transmitters mounted in the transmission device, transmitted the signal;
a determination step of the control unit determining using results of the detection whether a time for which a signal transmitted from a same transmitter that transmitted the signal has been received is equal to or longer than a preset period stored in a storage unit of the robot cleaner;
a continuous cleaning step of, if it is determined that the time for which the transmitted signal has been received is shorter than the preset period, the control unit continuously performing cleaning of a small region in which the robot cleaner is located by driving the robot cleaner; and
a movement step of, if it is determined that the time for which the transmitted signal has been received is equal to or longer than the preset period, the control unit moving the robot cleaner until a signal transmitted from another transmitter is received.

Abstract
The present invention relates to a robot cleaner system and a method of controlling a robot cleaner. When cleaning start information is received, a control unit (17) of the robot cleaner scans one cleaning area (30), thus calculating a cleaning time. The control unit performs cleaning of the cleaning area. When a signal transmitted from a transmission device (20) is received, the control unit detects which transmitter transmitted the signal. The control unit determines whether a time for which a signal transmitted from a same transmitter has been received is equal to or longer than a preset period. If the time is shorter than the preset period, the control unit continuously performs cleaning. If the time for which the transmitted signal has been received is equal to or longer than the preset period, the control unit moves the robot cleaner until a signal transmitted from another transmitter is received.
