9. A method for a robot cleaner to return to an external recharging apparatus so that a connection terminal of the robot cleaner is connected to a charging terminal of a charging stand, the method comprising the steps of:
-
a) receiving a charge request signal while the robot cleaner is traveling and cleaning a certain area as instructed by a user;
b) receiving infrared signals containing different codes and strengths, analyzing the different codes included in the infrared signals and controlling the robot cleaner to approach the charging stand; and
c) connecting the connection terminal of the robot cleaner to the charging terminal of the charging stand. - View Dependent Claims (10, 11)

12. A robot cleaner system comprising:
-
a first transmitter generating first signals, the first transmitter being associated with an external apparatus;
a second transmitter generating second signals, the second transmitter being associated with the external apparatus, the second signals having less strength than the first signals and having a different code than the first signals;
a receiving part for receiving the first and second signal, the receiving part being associated with a robot cleaner; and
a control part for controlling a movement of the robot cleaner based upon the first and second signals so that the robot cleaner is moved to a desired position with respect to the external apparatus. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
