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.
