Abstract

A cleaning robot is provided. The cleaning robot includes a main body, a moving assembly to move the main body around a home, an imaging unit to obtain images around the main body, a controller to generate a map of the home using the obtained images, and a communication unit to transmit the generated map to a home monitoring apparatus. A procedure to match location and type information of electric devices to a two-Dimensional (2D) or three-Dimensional (3D) map of the home may be automated. As described above, the map of the home may be realistically generated by utilizing a map generated by the cleaning robot and inconvenience experienced by a user to manually register electric devices located in each room of the home may be solved by automatically registering the electric devices.

First claim

What is claimed is:

a controller configured to:
generate a map of the home using the obtained images, and
identify location information of the electric device if communication of the electric device is performed,

wherein the communicator is further configured to transmit the generated map, the identified location information and information of the electric device to the home monitoring apparatus.

2. The cleaning robot according to claim 1 , wherein the communicator is further configured to communicate with an electric device disposed near the main body to receive basic information from the electric device.

3. The cleaning robot according to claim 2 , wherein the controller is further configured to:
match the basic information of the electric device to the identified location information in the generated map,
wherein the communicator is further configured to transmit the generated map to which the basic information of the electric device is matched, to the home monitoring apparatus.

4. The cleaning robot according to claim 1 , wherein the controller is further configured to:
perform image processing on the images, and
identify the location information of the electric device in the image-processed images.

5. The cleaning robot according to claim 1 , further comprising:
a cleaning tool configured to collect foreign substances on a floor of the home, wherein the controller is further configured to:
control operations of the moving assembly and the cleaning tool if a current mode is a cleaning mode,
communicate with an electric device of the home while performing cleaning,
determine whether the communicated electric device is a new electric device or a pre-registered electric device, and
update the map upon determining that the communicated electric device is the new electric device.

6. The cleaning robot according to claim 5 , further comprising:
a voice detector configured to detect voice,
wherein the controller is further configured to control the moving assembly to move to a location corresponding to the detected voice.

7. The cleaning robot according to claim 6 ,
wherein the voice detector comprises a microphone array, and
wherein the controller is further configured to recognize a location corresponding to a voice detected by the microphone array.

8. The cleaning robot according to claim 7 , wherein the controller is further configured to:
recognize the voice detected by the microphone array, and
determine a room designated by the recognized voice.

9. The cleaning robot according to claim 6 ,
wherein the voice detector comprises one microphone, and
wherein the controller is further configured to:
recognize a voice detected by the microphone, and
determine a room designated by the recognized voice.

10. The cleaning robot according to claim 1 , wherein the home monitoring apparatus is located at a charger station to supply power to the main body, and displays information about electric devices matched to the map of the home.

11. The cleaning robot according to claim 1 , wherein the home monitoring apparatus is located at the main body, and displays information about electric devices matched to the map of the home.

12. A cleaning robot, comprising:
a main body;
a moving assembly configured to move the main body around a home;
an image capturer including a first image capturing unit and a second image capturing unit aligned at different locations of the main body,
wherein the first image capturing unit and the second image capturing unit are configured to obtain two-dimensional (2D) images around the main body, respectively;
a controller configured to:
perform image processing on the captured 2D images to obtain a three-dimensional (3D) images recognize an electric device based on the obtained 3D images, and
generate a map to which the recognized electric device is matched; and

a communicator configured to transmit the map to which the recognized electric device is matched, to a home monitoring apparatus.

13. A cleaning robot, comprising:
a main body;
a moving assembly configured to move the main body around a home;
an image capturer including a first image capturing unit configured to capture two-dimensional (2D) images and a second image capturing unit configured to capture three-dimensional 3D images;
a controller configured to:
generate a map by distinguishing rooms of the home based on the 3D images,
perform image processing on at least one of the 2D and 3D images to recognize electric device, and
generate the map to which the recognized electric device are matched; and

a communicator configured to transmit the map to which the electric device are matched, to a home monitoring apparatus.

14. The cleaning robot according to claim 13 , wherein the controller is further configured to:
identify location information of an electric device if the electric device is recognized, and
match information of the electric device having the identified location information into the map.

15. The cleaning robot according to claim 14 , further comprising:
a storage configured to store the location information of the electric device using 3-axis values.

16. A method for controlling a cleaning robot having a main body, a moving assembly configured to move the main body around a home, and an image capturer configured to obtain images around the main body, the method comprising:
determining whether an operation command is a command to execute a map generating mode if the operation command is input;
operating and moving the moving assembly around the home if the operation command is a command to execute a map generating mode;
obtaining a plurality of two-dimensional (2D) images around the main body while moving around the home;
generating three-dimensional (3D) images using the 2D images;
generating a map of the home based on the obtained 2D images of the generated 3D images;
recognizing an electric device disposed around the home by performing image processing on the generated 3D images;
matching the recognized electric device to the generated map; and
transmitting the map to which the electric device is matched, to a home monitoring apparatus.

17. The method according to claim 16 , wherein the recognizing of the electric device comprises:
distinguishing rooms of the home using the generated 3D images; and
recognizing an electric device of each room.

18. A method for controlling a cleaning robot having a main body, a moving assembly configured to move the main body around a home, and an image capturer configured to obtain images around the main body, the method comprising:
