AI Technical Summary
Existing pipeline robot designs cannot adapt to pipelines of different diameters and angles, making it difficult to crawl across pipelines and navigate bends. In particular, support-type and multi-section designs fail when the diameter changes significantly or the pipeline angles are inconsistent, and wheel designs can only operate in horizontal pipelines.
The design of a magnetic pipe robot with two drive wheels utilizes the magnetic attraction between the magnetic wheels and the pipe. Combined with a differential drive method, the magnetic wheels are rotated in opposite directions by a control mechanism. Equipped with an attitude sensor for self-calibration and auxiliary components to prevent rollover, it achieves flexible steering and stable crawling.
It enables flexible circumferential and axial crawling within magnetic pipes of various angles and diameters, allowing for stable passage through bends and branch pipes. It possesses precise control capabilities, improving the robot's stability and adaptive adjustment capabilities.
