<p><P>PROBLEM TO BE SOLVED: To provide a system and a method for automatically returning a self-moving robot to a charger, capable of allowing the self-moving robot to accurately and quickly return to the charger when charging. <P>SOLUTION: The system for automatically returning the self-moving robot to the charger includes a charger 100 and a self-moving robot 300. The charger 100 includes an infrared module 120 for emitting infrared light in response to a charging request signal received from the robot 300 through a wireless transceiver 110, and outputting an infrared emission signal. The robot 300 outputs the charging request signal to the charger 100 when its battery voltage is lower than a reference voltage, and moves back to the charger using image information input from a camera module 310 in response to the infrared emission signal received from the charger 100. The robot 300 includes a microprocessor for controlling movement of the self-moving robot for returning to the charger, using position information of infrared light in a picture captured by the camera module 310 if the infrared light is detected in the picture input from the camera module 310. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
