Title:
PHOTOVOLTAIC CLEANING ROBOT BASED ON VISUAL SLAM
Document Type and Number:
WIPO Patent Application WO/2022/267336
Kind Code:
A1
Abstract:
Disclosed is a photovoltaic cleaning robot based on visual SLAM. The photovoltaic cleaning robot comprises a robot body (100), a rolling brush cleaning assembly (200), and a continuous track driving device (300); the robot body (100) is provided with a photosensitive sensor, an anti-falling sensor, a wheel encoder, and an inertial measurement unit; the photosensitive sensor is disposed at the front side of the top part of the robot body (100); the photosensitive sensor is used for sensing a surface image of a photovoltaic panel in front of the robot body (100); the anti-falling sensor is used for sensing the edges of a photovoltaic panel below the robot body (100) to prevent falling; the wheel encoder is used for acquiring the rotational speed of the continuous track driving device (300) and obtaining wheel mileage; and the inertial measurement unit is disposed on the continuous track driving device (300) and is used for measuring pose information of the robot body (100), coupling the wheel mileage and the pose information for basic positioning of the photovoltaic cleaning robot, and performing global auxiliary positioning by using the surface images of the photovoltaic panels. The cleaning robot can improve the automation degree and applicability to reduce manpower and power station maintenance costs.
