What is claimed is: 1. A robot cleaner system comprising: a first transmitter generating first infrared signals, the first transmitter being associated with an external apparatus; a second transmitter generating second infrared signals, the second transmitter being associated with the external apparatus, the second infrared signals having less strength than the first infrared signals and having a different code than the first infrared signals, wherein the codes of the infrared signals differ in wave size or shape; a receiving part simultaneously receiving the first and second infrared signals, 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 infrared signals so that the robot cleaner is moved to a desired position with respect to the external apparatus. 2. The robot cleaner system of claim 1, wherein the first transmitter comprises a pair of first transmitters provided on a face of the external apparatus. 3. The robot cleaner system of claim 2, wherein the second transmitter is on the face between the pair of first transmitters. 4. The robot cleaner system of claim 1, wherein the first signals have a first angle range and the second signals have a second angle range, and the second angle range being narrower than the first angle range. 5. The robot cleaner system of claim 1, further comprising a third transmitter generating third signals, the third transmitter being associated with the external apparatus, the third signals having less strength than the second signals. 6. The robot cleaner system of claim 5, wherein the first signals have a first angle range, the second signals have a second angle range, and the third signals have a third angle range, wherein in the second angle range is narrower than the first angle range and the third angle range is narrower than the second angle range. 7. The robot cleaner system of claim 5, wherein the third signals have a different code from the first infrared signals and the second infrared signals, and the codes of the infrared signals differ in wave size or shape. 8. The robot cleaner system of claim 5, wherein a plurality of second transmitters or a plurality of third transmitters are provided. 9. The robot cleaner system of claim 8, wherein the plurality of second transmitters are disposed on the front and both sides of the external apparatus. 10. The robot cleaner system of claim 5, wherein the third signals have a different code from the first infrared signals and the second infrared signals.
