Abstract

The present disclosure provides a moving robot including 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 area of a traveling area, and a controller which controls a traveler so that the traveler performs pattern traveling a plurality of times in the traveling area, and controls the traveler so that a traveling angle during first pattern traveling and a traveling angle during second pattern traveling are different from each other. Accordingly, when the pattern traveling is performed a plurality of times, the pattern traveling is performed at angles different from each other based on a reference axis, and it is possible to minimize an area which cannot be mowed and improve efficiency.

First claim

What is claimed is:

1. A moving robot system comprising:
a moving robot generating map information of a traveling area when driving within a boundary region of the traveling area, and mowing grass of a predetermined length for each one-time pattern traveling in the traveling area, wherein the one-time pattern traveling includes traveling the entire traveling area in a zigzag pattern while maintaining a specific traveling angle; and
a user terminal including a control application for the moving robot, receiving the map information of the traveling area from the moving robot, executing the control application to visualize the map information for the travelling area having structure for the travelling area and a visual reference line connecting a window and a door of the travelling area and setting the traveling angle of each time pattern traveling of the moving robot according to the visual reference line, and transmitting it to the moving robot,
wherein the moving robot receives the traveling angle for each pattern traveling from the user terminal when the moving robot travels in an n-time pattern traveling of the traveling area, and changes the traveling angle accordingly to complete the traveling.

2. The moving robot system of claim 1 , wherein the moving robot controls a traveler so that the traveler performs pattern traveling in the zigzag pattern in which the moving robot alternately travels a major axis and a minor axis.

3. The moving robot system of claim 2 , wherein the moving robot defines an angle of the major axis with respect to a reference line of the traveling area as the traveling angle, and angles of a first pattern traveling and a second pattern traveling are different from each other.

4. The moving robot system of claim 3 , wherein the user terminal sets the traveling angle so that the major axis is parallel to the visual reference line so that the moving robot travels and transmits a setting angle to the moving robot.

5. The moving robot system of claim 3 , wherein the moving robot transmits a request signal for requesting the travel angle of a next time to the user terminal when the first pattern traveling for the travel area is completed.

6. The moving robot system of claim 5 , when the n-time pattern traveling of the traveling is completed, the moving robot provides statistical information on a length of cut grass for each region within the traveling area to the user terminal.

7. The moving robot system of claim 3 , wherein the moving robot sets angles of the minor axis and the major axis according to the traveling angle of a new major axis.

8. The moving robot system of claim 3 , wherein the moving robot sets the traveling angle so that, during a last pattern traveling, the moving robot travels an area, in which the moving robot travels equal to or less than a critical count, of traveling areas up to a previous pattern traveling.

9. The moving robot system of claim 3 , further comprising a boundary wire which defines the traveling area.

10. The moving robot system of claim 9 , wherein the moving robot includes:
a body which forms an appearance;
the traveler which moves the body;
a boundary signal detector which detects a boundary signal generated in a boundary area of a traveling area; and
a controller which controls the traveler so that the traveler performs pattern traveling a plurality of times in the traveling area.

11. The moving robot system of claim 10 , further comprising:
a docking device to which the moving robot is docked to be charged,
wherein one end of the boundary area is disposed to be adjacent to the docking device.

12. The moving robot system of claim 11 , wherein the docking device further includes a first wire terminal and a second wire terminal connected to a power source, and
wherein one end of the boundary wire is connected to the first wire terminal and a second end of the boundary wire is connected to the second wire terminal.
