1. A robot cleaner comprising:
- a main body;
a moving device to move the main body;
a control unit at the main body to recognize an area requiring cleaning;
a camera at the main body to take an image in a vicinity of the main body; and
a memory in which reference image information acquired by taking an image in the vicinity of the main body when the area is clean, and map information are stored,wherein, when the control unit recognizes the area requiring cleaning while in a standby state of the robot cleaner, the control unit controls the moving device so that the main body moves from a standby position to the area requiring cleaning to clean the area based on the control unit recognizing the area requiring cleaning, andwherein the control unit recognizes the area requiring cleaning by using the reference image information stored in the memory and image information related to an image subsequently taken by the camera, andrecognizes coordinate information of the area requiring cleaning from the map information.

Abstract
A robot cleaner includes a main body, a moving device to move the main body, and a control unit at the main body to recognize an area requiring cleaning. When the control unit recognizes the area requiring cleaning while in a standby state of the robot cleaner, the control unit controls the moving device so that the main body moves from a standby position to the area requiring cleaning to clean the area based on the control unit recognizing the area requiring cleaning.

1. A robot cleaner comprising:
-
a main body; a moving device to move the main body; a control unit at the main body to recognize an area requiring cleaning; a camera at the main body to take an image in a vicinity of the main body; and a memory in which reference image information acquired by taking an image in the vicinity of the main body when the area is clean, and map information are stored, wherein, when the control unit recognizes the area requiring cleaning while in a standby state of the robot cleaner, the control unit controls the moving device so that the main body moves from a standby position to the area requiring cleaning to clean the area based on the control unit recognizing the area requiring cleaning, and wherein the control unit recognizes the area requiring cleaning by using the reference image information stored in the memory and image information related to an image subsequently taken by the camera, and recognizes coordinate information of the area requiring cleaning from the map information. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A robot cleaner comprising:
-
a main body; a moving device to move the main body; and a control unit at the main body to recognize a cleaning restriction area, wherein when the control unit recognizes an area requiring cleaning while in a standby state of the robot cleaner, the control unit controls the moving device such that the main body cleans the area requiring cleaning based on the control unit recognizing the area requiring cleaning except for the cleaning restriction area, and when a proportion of the cleaning restriction area to an entire cleaning target area is greater than a reference proportion, the control unit controls the robot cleaner to stop the cleaning and to return to a standby position. - View Dependent Claims (9, 10, 11, 12, 13)

14. A robot cleaner comprising:
-
a main body; a moving device to move the main body; a control unit at the main body to recognize an area requiring cleaning; a communication unit at the main body to communicate with an external detection device; and a memory at the main body to store map information, wherein, when the control unit recognizes the area requiring cleaning while in a standby state of the robot cleaner, the control unit controls the moving device so that the main body moves from a standby position to the area requiring cleaning to clean the area based on the control unit recognizing the area requiring cleaning, and wherein the communication unit receives image information including information related to the area requiring cleaning from the external detection device, and the control unit uses the received image information and the map information stored in the memory to recognize a coordinate of the area requiring cleaning.
