Abstract

An embodiment of the invention provides a control method of a cleaning robot. The method includes the steps of: forming a cleaning area according to at least three points which are selected from a light generating device, a charging station or an obstacle; moving the cleaning robot along an outer of the cleaning area from a first position; recording a first cleaning route when the cleaning robot returns back to the first position; moving the cleaning robot to a second position and planning a second cleaning route according to the first cleaning route; and moving the cleaning robot along the second cleaning route.

Claims

1. A control method for a cleaning robot, comprising:

forming a cleaning area according to at least three means which are selected from a light generating device, a charging station or an obstacle;

circling along an outline of the cleaning area from a first position;

recording a first cleaning route when the cleaning robot returns back to the first position;

moving the cleaning robot to a second position and planning a second cleaning route according to the first cleaning route; and

circling along the second cleaning route.

2. The method as claimed in claim 1, wherein a distance between the first position and the second position is a first distance.

3. The method as claimed in claim 2, wherein the first distance is half of a width of the cleaning robot.

4. The method as claimed in claim 1, further comprising:

estimating a center of the cleaning area,

wherein when the second position is the center of the cleaning area, the cleaning robot does not move along the second route and finishes its work.

5. The method as claimed in claim 1, further comprising:

estimating a center of the cleaning area,

wherein when a distance between the second position and the center of the cleaning area is less than a predetermined distance, the cleaning robot does not move along the second route and finishes its work.

6. The method as claimed in claim 5, wherein the predetermined distance is half of a width of the cleaning robot.

7. The method as claimed in claim 1, further comprising:

when the cleaning robot detects a light beam output by the light generating device, the cleaning robot moving along the light beam.

8. A control method for a cleaning robot, comprising:

forming a cleaning area according to at least three means which are selected from a light generating device, a charging station or an obstacle;

estimating a center of the cleaning area;

moving the cleaning robot to the center of the cleaning area; and

moving the cleaning robot in a spiral route and cleaning the cleaning area.

9. The method as claimed in claim 8, further comprising:

when the cleaning robot detects a light beam output by the light generating device, the cleaning robot moving along the light beam.
