ROBOT CLEANING SYSTEM AND METHOD FOR CHARGING THE SAME
First Claim
1. A robot cleaning system comprising:
- a robot cleaner comprising;
a sensor for receiving a specific signal sound,a rechargeable battery, anda control unit; and
a recharging base comprising;
an audio output device for outputting the specific signal sound,wherein the control unit calculates a distance and a direction from the robot cleaner to the recharging base based on the signal sound received by the sensor, and controls the robot cleaner to move based on the calculated distance and direction, when a remaining amount of the battery is less than a preset value, andwherein the robot cleaner docks with the recharging base to recharge the battery of the robot cleaner.

Abstract
A robot cleaning system includes a robot cleaner comprising a sensor for receiving a specific signal sound, a rechargeable battery, and a control unit; and a recharging base comprising an audio output device for outputting the specific signal sound. The control unit calculates a distance and a direction from the robot cleaner to the recharging base based on the signal sound received by the sensor, and controls the robot cleaner to move based on the calculated distance and direction, when a remaining amount of the battery is less than a preset value. The robot cleaner docks with the recharging base to recharge the battery of the robot cleaner.

11. A method for recharging a robot cleaner comprising:
-
checking, by a control unit of a robot cleaner, a remaining amount of a battery in the robot cleaner; sensing, by a sensor of the robot cleaner, a specific signal sound generated by an audio output device of a recharging base, when the remaining amount of the battery is below a preset value; calculating, by the control unit, a direction and a distance from the robot cleaner to the recharging base, based on the received specific signal sound; controlling, by the robot cleaner control unit, the robot cleaner to drive based on the calculated direction and distance and to dock with the recharging base; and controlling, by a control unit of the recharging base, the recharging base to recharge the battery of the robot cleaner. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
