Abstract

According to a moving robot and a control method of a moving robot of the present disclosure, it is possible to reset a position of the moving robot by returning to a charging station after completing a work in one traveling zone and continuously perform a work.

First claim

What is claimed is:

1 . A moving robot comprising:
a body which forms an appearance; a traveler which moves the body; a boundary signal detector which detects a boundary signal generated in a boundary of a traveling area and a docking position signal generated in a docking device; an azimuth sensor which senses an acceleration of the body; and a controller which defines the traveling area based on the boundary signal, wherein when a position correction of the moving robot is required while the moving robot travels the traveling area, the controllers resets a position of a moving robot based on a position of the docking device after the moving robot moves to the docking device.

2 . The moving robot of claim 1 , wherein the controller controls the traveler so that the moving robot continues to travel an incomplete traveling in the traveling area after the moving robot resets the position of the moving robot.

3 . The moving robot of claim 1 , wherein the controller controls the traveler so that the moving robot moves along the boundary signal when the moving robot moves to the docking device.

4 . The moving robot of claim 1 , wherein the controller controls the traveler so that the moving robot changes a traveling direction by a random number of times within an area set with a boundary line calculated based on the boundary signal as a central axis when the moving robot moves to the docking device.

5 . The moving robot of claim 1 , wherein the boundary signal detector distinguishes the docking position signal and the boundary signal by a difference in a direction of a magnetic field.

6 . The moving robot of claim 1 , wherein a case where a position correction of the moving robot is required is when a preset time elapses from a traveling start of the moving robot.

7 . The moving robot of claim 1 , wherein the controller defines the traveling area based on the boundary signal and divides the traveling area into a plurality of traveling areas including at least a first traveling area and a second traveling area, and
a case where a position correction of the moving robot is required is when the moving robot completes traveling of the first traveling area.

8 . The moving robot of claim 7 , wherein the controller controls the traveler so that the moving robot travels the second traveling area after the moving robot resets the position of the moving robot.

9 . The moving robot of claim 7 , wherein the controller controls the traveler so that the moving robot moves along the boundary signal to a traveling starting point of the second traveling area after the moving robot resets the position of the moving robot.

10 . The moving robot of claim 8 , wherein the azimuth sensor calculates a direction angle of the body, and
the controller controls the traveler so that the moving robot performs a first pattern traveling in the first traveling area at a first direction angle and performs a second pattern traveling in the second traveling area at a second direction angle intersecting the first direction angle.

11 . A control method of a moving robot comprising:
a division step of defining a traveling area based on a boundary signal and dividing the traveling area into a first traveling area and a second traveling area; a first traveling step of the moving robot traveling in the first traveling area; a returning step of the moving robot returning to a docking device after completing the first traveling; and a position correction step of resetting the position of the moving robot based on a docking position signal generated in the docking device.

12 . The control method of a moving robot, further comprising:
a movement step of the moving robot moving to a traveling starting portion of the second traveling area after the position correction step; and a second traveling step of the moving robot traveling the second traveling area at the traveling starting point of the second traveling area.

13 . The control method of a moving robot, wherein the moving moves along the boundary signal when moving to the traveling starting point of the second traveling area.

14 . A control method of a moving robot comprising:
a traveling area definition step of defining a traveling area based on a boundary signal; a traveling step of a moving robot traveling the traveling area; a returning step of the moving robot returning to a docking device when a preset time elapses from a traveling starting point while the moving robot travels the traveling area; and a position correction step of resetting a position of the moving robot based on a docking position signal generated in the docking device.

15 . The control method of a moving robot according to claim 14 , further comprising:
a continuous traveling step of the moving robot continuing to travel incomplete traveling of the traveling area after the position correction step.
