SYSTEM AND METHOD FOR AUTOMATICALLY RETURNING SELF-MOVING ROBOT TO CHARGER
First Claim
1. A system for automatically returning a self-moving robot to a charger, the system comprising:
- the charger, including an infrared module, for emitting infrared light in response to a charging request signal received from the self-moving robot through a wireless transceiver and outputting an infrared emission signal according to the emission of the infrared light; and
the self-moving robot for outputting the charging request signal to the charger when a battery voltage of the self-moving robot is lower than a reference voltage and moving back to the charger using image information input from a camera module in response to the infrared emission signal received from the charger, the self-moving robot including a microprocessor for controlling movement of the self-moving robot to return the self-moving robot to the charger, using position information of infrared light in a picture input from the camera module, if the infrared light is detected in the picture input from the camera module.

Abstract
A system and method for automatically returning a self-moving robot to a charger is provided. The charger emits infrared light from an infrared module in response to a charging request signal received from the self-moving robot through a wireless transceiver, and outputs an infrared emission signal according to the infrared light emission. The self-moving robot communicates a variety of data with the charger, outputs the charging request signal to the charger when its battery level is lower than a reference level, and moves back to the charger using image information input from a camera module in response to the infrared emission signal from the charger. The self-moving robot 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 input from the camera module, if the infrared light is detected in the picture input from the camera module.
