SOLAR PANEL CLEANING DEVICE

WIPO Patent Application WO/2014/196480

A1

In order to cause a main body autonomously traveling on a light receiving surface of a solar panel to travel so as not to deviate a predetermined cleaning line, the cleaning line is set in a direction parallel to a straight line observed on the light receiving surface, a camera (7) for capturing an image of the light receiving surface in front of the main body (1) that is autonomously traveling, an image processing unit (8) for extracting the straight line as an extracted line from the captured image captured by the camera (7) and detecting the inclination of the extracted line, and a steering means for steering the direction of travel of the main body (1) by a pair of right and left crawlers (2) are provided, and on the basis of the change of the inclination of the extracted line detected by the image processing unit (8), control for making a difference in speed between the right and left crawlers (2) as the steering means is performed so as to return the main body (1) to the cleaning line.
