Abstract

The present disclosure provides a moving robot including a body which forms an appearance, a traveler which moves the body with respect to a traveling surface in a traveling area, a sensing unit which acquires environment information of the traveling area, and a controller which sets a parameter tailored to the traveling area according to the environment information and performs pattern traveling of the traveling area. Accordingly, even when information on an environment in which the moving robot is installed is not obtained from a manufacture in advance, the moving robot can directly obtain information on the corresponding environment and set an optimum parameter according to the environment to increase efficiency.

First claim

What is claimed is:

1. A moving robot comprising:
a body which forms an appearance;
a traveler which moves the body with respect to a traveling surface in a traveling area;
a sensing unit which acquires environment information of the traveling area; and
a controller which sets a parameter tailored to the traveling area according to the environment information and performs pattern traveling of the traveling area,
wherein the controller obtains information on a lawn condition in the traveling area as the environment information, sets a parameter for bumper sensitivity according to the information on the lawn condition, and performs the pattern driving.

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

3. The moving robot of claim 2 , wherein the controller includes slope information of the traveling surface, as the environment information.

4. The moving robot of claim 3 , wherein the controller includes information on a lawn length and a lawn density, as information on the lawn condition.

5. The moving robot of claim 3 , wherein the controller performs slope compensation so that the moving robot travels in a slope upward direction on the traveling surface based on the slope information.

6. The moving robot of claim 3 , wherein the controller controls the traveler in the traveling area to perform a preceding traveling to obtain the environment information.

7. The moving robot of claim 1 , wherein the controller sets the bumper sensitivity higher as the lawn density increases or the lawn length increases.

8. A moving robot system comprising:
a boundary wire which defines a traveling area;
a moving robot which includes a body which forms an appearance, a traveler which moves the body with respect to a traveling surface in the traveling area, a sensing unit which acquires environment information of the traveling area, and a controller which sets a parameter tailored to the traveling area according to the environment information and performs pattern traveling of the traveling area; and
a user terminal which transmits information on the parameter to the moving robot,
wherein the controller obtains information on a lawn condition in the traveling area as the environment information, sets a parameter for bumper sensitivity according to the information on the lawn condition, and performs the pattern driving.

9. The moving robot system of claim 8 , wherein the controller controls the traveler so that the traveler performs pattern traveling in a zigzag mode in which the moving robot alternately travels a major axis and a minor axis.

10. The moving robot system of claim 9 , wherein the user terminal stores an application for the moving robot.

11. The moving robot system of claim 10 , wherein the controller transmits information on the traveling area to the user terminal.

12. The moving robot system of claim 11 , wherein the information on the traveling area includes the environment information and gradient information on a sloped surface.

13. The moving robot system of claim 12 , wherein the user terminal receives simulation of a pattern path according to a value of a slope compensation from the moving robot.

14. The moving robot system of claim 8 , further comprising:
a docking device to which the moving robot is docked to be charged,
wherein one end of the traveling area is disposed to be adjacent to the docking device.
