Abstract

Disclosed are a mobile apparatus and a method for controlling the same. More particularly, disclosed are an autonomous mobile apparatus and a method for controlling the same. The method for controlling an autonomous mobile apparatus disclosed in the specification includes: recognizing a direction of a call signal based on the call signal; receiving and analyzing video information regarding the direction; estimating a position of a signal source of the call signal using the sound source localization and the detected person'"'"'s shape; generating a moving command to the position of the signal source; and recognizing the subject of the signal source after movement according to the moving command.

Claims

1. A method for controlling an autonomous mobile apparatus, comprising:

recognizing, by an analyzer, a direction of a call signal based on the call signal;

receiving and analyzing, by the analyzer, video information regarding the direction;

estimating, by an estimator, a position of a signal source of the call signal using the sound source localization and the detected person'"'"'s shape;

generating, by a navigation controller, a moving command to the position of the signal source; and

recognizing, by the analyzer, the signal source after movement according to the moving command.

2. The method of claim 1, wherein the call signal includes a voice signal.

3. The method of claim 2, wherein the recognizing includes recognizing, by the analyzer, the voice signal.

4. The method of claim 3, wherein the recognizing of the signal source includes generating a signal corresponding to the recognized voice signal.

5. The method of claim 1, wherein in the analyzing, the analyzer analyzes correspondence between the call signal and the video information regarding the direction.

6. The method of claim 1, wherein in the estimating, the estimator performs estimation the call signal and the video information regarding the direction.

7. The method of claim 1, wherein the generating of the moving command includes generating, by a navigation controller, a command of changing a path based on a signal sensed by an ultrasonic and/or bumper sensor.

8. The method of claim 1, wherein the recognizing of the signal source includes receiving, by the analyzer, the video information of the signal source after the movement to recognize the signal source.

9. An autonomous mobile apparatus, comprising:

a sensor module configured to sense a call signal and video information;

a navigation module configured to include a driver; and

a controller configured to control the navigation module based on the sensor module,

wherein the controller includes;

an analyzer configured to recognize a direction of the call signal based on the input call signal and receive and analyze video information regarding the direction;

an estimator configured to estimate a position of a signal source of the call signal using the sound source localization and the detected person'"'"'s shape; and

a navigation controller configured to generate the moving command to the estimated position of the signal source to generate the navigation module, and

wherein the analyzer recognizes the signal source by using the sensor module after movement according to the moving command.

10. The autonomous mobile apparatus of claim 9, wherein the call signal includes a voice signal.

11. The autonomous mobile apparatus of claim 10, wherein the analyzer includes a voice recognition unit that recognizes the voice signal.

12. The autonomous mobile apparatus of claim 11, wherein the controller further includes a response generating unit that generates a signal corresponding to the recognized voice signal.

13. The autonomous mobile apparatus of claim 9, wherein the analyzer includes a correspondence analyzer that analyzes correspondence between the call signal and the video information regarding the direction.

14. The autonomous mobile apparatus of claim 9, wherein the estimator performs estimation based on the call signal and the video information regarding the direction.

15. The autonomous mobile apparatus of claim 9, wherein the navigation controller includes an ultrasonic and/or bumper sensor module and controls the navigation module to change a path based on a signal sensed by the ultrasonic and/or bumper sensor module.

16. The autonomous mobile apparatus of claim 9, wherein the analyzer receives the video information of the signal source after the movement to recognize the signal source.
