Abstract

A robot cleaner includes an environment information detecting unit configured to obtain environment information regarding at least a portion of a cleaning area, a first communication unit configured to transmit and receive data to and from a different device positioned within the cleaning area, and a control unit configured to generate a control command regarding the different device in order to adjust the obtained environment information.

Claims

1. A robot cleaner comprising:

an environment information detecting unit configured to obtain environment information regarding at least a portion of a cleaning area;

a first communication unit configured to transmit and receive data to and from a different device positioned within the cleaning area; and

a control unit configured to generate a control command regarding the different device in order to adjust the obtained environment information.

2. The robot cleaner of claim 1, further comprising:

a storage unit configured to store the environment information and corresponding position information.

3. The robot cleaner of claim 1, further comprising:

a storage unit configured to store position information regarding the different device,

wherein the control unit generates a control command regarding a different device at a position corresponding to the environment information.

4. The robot cleaner of claim 1, wherein the environment information detecting unit detects at least one of a temperature, humidity, atmospheric pressure, and an air pollution level around the robot cleaner.

5. The robot cleaner of claim 1, further comprising:

a second communication unit configured to transmit and receive data to and from a terminal device generating a control command regarding the different device,

wherein the control unit transmits the environment information to the terminal device.

6. The robot cleaner of claim 5, wherein when the environment information is outside of a preset range, the second communication unit transmits the environment information to the terminal device through an SNS server and receives a control message regarding the different device through the SNS server, and

the control unit generates a control command regarding the different device on the basis of the control message.

7. The robot cleaner of claim 1, further comprising:

a storage unit configured to store environment information for a predetermined period of time,

wherein the control unit calculates a predetermined pattern regarding a time range in which the environment information is outside of a preset range, and generates a control command regarding the different device before the time range estimated on the basis of the predetermined pattern is reached.

8. The robot cleaner of claim 1, further comprising:

an obstacle detecting unit configured to detect an obstacle of the cleaning area using at least one sensor; and

a position recognizing unit configured to recognize a position of the robot cleaner using at least one sensor,

wherein the control unit generates a cleaning map regarding the cleaning area on the basis of information regarding the obstacle detected by the obstacle detecting unit and information regarding the position recognized by the position recognizing unit.

9. The robot cleaner of claim 8, further comprising:

a storage unit configured to store the environment information and corresponding position information,

wherein the position information is information indicating a region divided on the basis of the obstacle in the cleaning area.

10. The robot cleaner of claim 1, wherein the environment information detecting unit comprises an air sensor configured to sense dust in the air or a material included in the air.

11. The robot cleaner of claim 10, further comprising:

an air purifying unit configured to deodorize or sterilize sucked air,

wherein the control unit purifies the sucked air using the air purifying unit on the basis of pollution information sensed by the air sensor.

12. The robot cleaner of claim 1, further comprising:

a storage unit configured to store position information regarding the different device,

wherein the control unit recognizes environment information of a position corresponding to the position information of the different device, as environment information detected by the different device.

13. The robot cleaner of claim 12, wherein the environment information includes at least one of a temperature, humidity, atmospheric pressure, and an air pollution level.

14. The robot cleaner of claim 12, further comprising:

an air purifying unit configured to deodorize or sterilize sucked air,

wherein the control unit purifies the sucked air using the air purifying unit on the basis of an air pollution level detected by the different device.

15. The robot cleaner of claim 1, further comprising:

an output unit configured to output the environment information to the outside in a visual or audible manner

16. The robot cleaner of claim 15, wherein, when the environment information is outside of a preset range, the control unit outputs an alarm signal through the output unit.

17. A remote control system of a robot cleaner, the remote control system comprising:

a robot cleaner according to claim 1; and

a terminal device configured to generate a control command regarding the robot cleaner and the different device.

18. A method of controlling a robot cleaner, the method comprising:

obtaining environment information regarding at least a portion of a cleaning area;

generating a control command regarding a different device positioned within the cleaning area in order to adjust the obtained environment information; and

transmitting the control command to the different device.

19. The method of claim 18, further comprising;

when the environment information is outside of a preset range, transmitting the environment information to a terminal device through an SNS server; and

receiving a control message regarding the different device from the terminal device through the SNS server,

wherein, in the generating of the control command, the control command regarding the different device is generated on the basis of the control message.

20. The method of claim 18, wherein, in the obtaining of the environment information, an air sensor senses dust in the air or a material included in the air,

wherein the method further comprising:

deodorizing or sterilizing sucked air on the basis of pollution information sensed by the air sensor.
