Abstract

An artificial intelligence (AI) robot and a method for controlling the AI robot, includes detecting a target object changing its position in a travel area after determining a condition of the travel area based on an image captured by an image capturing unit while the AI robot is traveling in the travel area. The AI robot is controlled to travel based on the target object detected.

First claim

What is claimed is:

1 . A robot, comprising:
a main body; a driving unit configured to move the main body; an image capturing unit configured to capture an image of a travel area around the main body to generate image information regarding the travel area of the main body; and a controller configured to:
control traveling of the main body by determining a condition of the travel area based on the captured image while the main body is traveling in the travel area,
detect a target object changing its position in the travel area after determining the condition of the travel area while the main body is traveling in the travel area, and control the main body to travel in response to the detection of the target object changing its position in the travel area.

2 . The robot of claim 1 , wherein the image capturing unit is disposed at an upper portion of a rear side of the main body.

3 . The robot of claim 1 , wherein the image capturing unit is configured to capture an image of a traveling direction of the main body.

4 . The robot of claim 1 , wherein the controller is configured to detect an object changing its position among objects captured in the image information, and identify the detected object as the target object.

5 . The robot of claim 1 , wherein the controller is configured to control the main body to travel in response to detection of the target object based on a plurality of preset control modes.

6 . The robot of claim 5 , wherein the plurality of control modes comprises:
a first control mode configured to control the main body to travel slowly; a second control mode configured to control the main body to stand by; and a third control mode configured to control the main body to travel by avoiding the target object.

7 . The robot of claim 6 , wherein the controller is configured to control the main body to travel while maintaining at least a predetermined distance between the main body and the target object, when the main body is controlled to travel according to one or more of the plurality of control modes.

8 . The robot of claim 5 , wherein the controller is configured to control the main body to travel according to one or more of the plurality of control modes until the target object is no longer detected.

9 . The robot of claim 1 , wherein the controller is configured to determine a type of the target object based on a result of detecting the target object and comparing the detected target object with a predetermined detection reference, and control the main body to travel according to the determined type of the target object.

10 . The robot of claim 1 , further comprising a communication unit configured to communicate with an external communication target element,
wherein the controller is configured to generate notification information of a result of detecting the target object, and transmit the notification information to the communication target element from the communication unit.

11 . The robot of claim 1 , further comprising an output unit configured to output an audio output,
wherein the controller is configured to generate an alarm signal based on a result of detecting the target object, so that an audio output is output from the output unit based on the alarm signal.

12 . A method for controlling a robot including a main body, a driving unit configured to move the main body, an image capturing unit configured to capture an image around the main body to generate image information regarding a travel area of the main body, and a controller configured to control traveling of the main body by controlling the driving unit and determine a condition of the travel area based on the image information, the method comprising:
generating image information by capturing an image around the main body while the robot is traveling in the travel area; detecting a target object changing its position in the travel area based on the image information; and controlling the main body to travel based on a result of the detection.

13 . The method of claim 12 , wherein detecting the target object changing its position in the travel area based on the image information includes detecting the target object among objects captured in the image information by recognizing that the target object is changing its position.

14 . The method of claim 12 , wherein controlling the main body to travel based on the result of the detection includes controlling the main body to travel in response to movement of the target object when the target object is detected.

15 . The method of claim 14 , wherein controlling the main body to travel based on the result of the detection includes determining a type of the target object based on a comparison of the result of the detection and a predetermined detection reference, and controlling the main body to travel based on the determined type of the target object.

16 . The method of claim 15 , wherein controlling the main body to travel includes at least one of control modes, comprising:
a first control mode configured to control the main body to travel slowly; a second control mode configured to control the main body to stand by; and a third control mode configured to control the main body to travel by avoiding the target object.

17 . A robot, comprising:
a main body; a driving unit configured to move the main body; an image capturing unit configured to capture an image of a travel area around the main body to generate image information regarding the travel area of the main body; and a controller configured to:
control traveling of the main body by determining a condition of the travel area based on the captured image while the main body is traveling in the travel area,
detect a target object changing its position in the travel area,
determine a type of the target object based on a result of detecting the target object and comparing the detected target object with a predetermined detection reference, and
control the main body to travel in response to the detection of the target object changing its position in the travel area, wherein the control of the main body to travel in response to the detection of the target object is based on a plurality of preset control modes and the determined type of the target object.

18 . The robot according to claim 17 , further comprising a communication unit configured to communicate with an external communication target element,
wherein the controller is configured to generate notification information of a result of detecting the target object, and transmit the notification information to the communication target element from the communication unit.

19 . The robot according to claim 17 , further comprising an output unit configured to output an audio output,
wherein the controller is configured to generate an alarm signal based on a result of detecting the target object, so that an audio output is output from the output unit based on the alarm signal.

20 . The robot according to claim 17 , wherein the plurality of control modes comprises:
a first control mode configured to control the main body to travel slowly; a second control mode configured to control the main body to stand by; and a third control mode configured to control the main body to travel by avoiding the target object.
