Abstract

Provided is a lawn mower for forming images. The lawn mower includes: an image input unit receiving an image to be formed in a lawn area; a position detection unit detecting position information of the lawn mower on a movement path of the lawn mower; a lawn mowing unit processing a lawn according to any one of a plurality of lawn processing patterns which corresponds to each position on the movement path while the lawn mower moves along the movement path; and a control unit analyzing the image received from the image input unit, determining a lawn processing pattern, which corresponds to the position information detected by the position detection unit, to express the image in the lawn area and controlling the lawn mowing unit according to the determined lawn processing pattern and independently of the movement path.

Claims

1. A lawn mower for forming images, the lawn mower comprising:

an image input unit configured to receive an image to be formed in a lawn area;

a position detection unit configured to detect position information of the lawn mower on an arbitrary movement path of the lawn mower;

a lawn mowing unit configured to process a lawn according to any one of a plurality of lawn processing patterns which corresponds to each position on the arbitrary movement path while the lawn mower moves along the arbitrary movement path, wherein the lawn mowing unit comprises a processor with at least one of a direction and height that is adjustable independently of the arbitrary movement path of the lawn mower; and

a control unit configured to analyze the image received from the image input unit, further configured to determine a lawn processing pattern, which corresponds to the position information detected by the position detection unit, to express the image in the lawn area, and further configured to control the lawn mowing unit according to the determined lawn processing pattern and being independent of the arbitrary movement path of the lawn mower.

2. The lawn mower of claim 1, wherein the arbitrary movement path is determined by at least one of a user and the control unit.

3. The lawn mower of claim 1, wherein the lawn processing patterns comprise a first pattern processed along a predetermined direction and a second pattern processed in a direction different from the predetermined direction.

4. The lawn mower of claim 3, wherein the lawn processing patterns comprise three or more patterns having different directions.

5. The lawn mower of claim 1, wherein the lawn processing patterns comprise a first pattern having a predetermined height and a second pattern having a height different from the predetermined height.

6. The lawn mower of claim 5, wherein the lawn processing patterns comprise three or more patterns having different heights.
