Abstract

A robot cleaner is provided that includes a driver configured to move the robot cleaner, and a suction unit configured to suck foreign objects from a surface below the robot cleaner. The robot cleaner also includes a detector configured to capture images of regions disposed in front of the robot cleaner. The robot cleaner further includes a controller configured to control the detector to capture a first image of a region before cleaning, control the detector to capture a second image of the region after cleaning, and generate cleaning result information using the first and second images.

Claims

1. A robot cleaner comprising:

a driver configured to move the robot cleaner;

a suction unit configured to suck foreign substances from a surface below the robot cleaner;

a detector configured to capture images of regions disposed in front of the robot cleaner and detect liquid under the robot cleaner; and

a controller configured to control the detector to capture a first image of a region before cleaning, control the detector to capture a second image of the region after cleaning, and generate cleaning result information using the first and second images,

wherein the controller is configured to stop driving the robot cleaner in response to the liquid under the robot cleaner being detected by the detector.

2. The robot cleaner as claimed in claim 1, further comprising a communication interface configured to receive schedule information of a user from a server,

wherein the controller is further configured to generate a cleaning schedule of the robot cleaner based on the schedule information and perform a cleaning job according to the cleaning schedule.

3. The robot cleaner as claimed in claim 2, further comprising a storage unit configured to store a plurality of cleaning schedules to be performed by the robot cleaner,

wherein each of the plurality of cleaning schedules has a different cleaning time.

4. The robot cleaner as claimed in claim 2, wherein:

the suction unit is further configured to perform suction according to a plurality of operation modes;

the communication interface is further configured to receive weather information from the server; and

the controller is further configured to control the suction unit to be operated in one of the plurality of operation modes corresponding to the weather information.

5. The robot cleaner as claimed in claim 1, wherein:

the detector is further configured to detect an object in front of the robot cleaner; and

the controller is further configured to determine whether or not the object is a suckable object, and determine a region in which the object is located as a non-cleanable region when the detected object is not the suckable object.

6. The robot cleaner as claimed in claim 5, wherein, when the object is the suckable object, the controller is further configured to capture the first image of the object, control the driver and the suction unit to suck the object, and control the driver and the detector to capture the second image of the region in which the object was located.

7. The robot cleaner as claimed in claim 5, wherein:

the detector comprises;

a first capturing unit configured to capture regions in front of the robot cleaner; and

a second capturing unit configured to capture regions behind the robot cleaner, which opposite of in front of the robot cleaner, and

when the object is the suckable object, the controller is further configured to capture the first image of the object using the first capturing unit, control the driver and the suction unit to suck the object, and control the second capturing unit to capture the second image of the region in which the object was located after suction of the object.

8. The robot cleaner as claimed in claim 5, wherein the detector is further configured to determine a type of the object based on a sound pattern generated in sucking of the object.

9. The robot cleaner as claimed in claim 1, further comprising a communication interface configured to transmit the cleaning result information to a preset terminal apparatus in response to cleaning being completed.

10. The robot cleaner as claimed in claim 1, wherein:

the detector is further configured to detect a degree of dust on the surface, and

the controller is further configured to determine a cleaning state in a region in which a cleaning job is completed according to the degree of dust detected through the detector.

11. The robot cleaner as claimed in claim 10, wherein the detector comprises:

an air exhaust unit disposed on a bottom side of the robot cleaner and configured to discharge air toward the surface; and

a dust sensor configured to detect the degree of dust in the air input to the suction unit.
