An object of the present invention

An object of the present invention is to provide a robot cleaning system that remotely controls a cleaning operation at long distances through a mobile communication terminal and controls a cleaning operation from off-site by processing the image data photographed in the cleaning robot through a mobile communication network.

The above object is accomplished by providing a robot cleaning system comprising: a cleaning robot for cleaning by moving freely in a cleaning place or area by control data transmitted in the mobile communication signal; a mobile communication relaying apparatus for receiving the mobile communication signal transmitted from the cleaning robot and another mobile communication signal to control the cleaning robot, and relaying the mobile communication signals to a corresponding remote apparatus; and a mobile communication terminal for transmitting command signals, for performing operations, to the cleaning robot through the mobile communication relaying apparatus.

The cleaning robot comprises: a driving unit for moving a robot body; a self-position recognition unit having a camera and a sensor for recognizing a current position of the robot body; an obstacle detection unit having a camera and a sensor for detecting obstacles adjacent the robot body; a vacuum cleaning unit for collecting dust on a floor; a mobile communication module for transmitting the mobile communication signal with the mobile communication relaying apparatus; and a controller for controlling each of the units to move and clean the cleaning area corresponding to the control data transmitted from the mobile communication module.

The controller transmits the operation completion data to the mobile communication terminal when an operation is completed in accordance with the transmitted control data.

The controller transmits an image photographed through the camera of the self-position recognition unit and the camera of the obstacle detection unit to the mobile communication relaying apparatus.

The robot cleaning system further comprises an image process server for analyzing the image data transmitted through the mobile communication relaying apparatus, and for transmitting the control data according to the analyzed result to the cleaning robot through the mobile communication relaying apparatus.

The image process server comprises: an interface for interfacing a data with the mobile communication relaying apparatus; an image process unit for processing the image data transmitted through the interface; and a controller for analyzing the image data processed at the image process unit, for creating the control data according to the analyzed result, and for outputting the control data to the interface.

Here, the interface of the image process server can transmit the image data by Internet from the mobile communication relaying apparatus through a mobile communication relay base, or directly receive an RF signal from the mobile communication relaying apparatus.
