A V‐Shaped In‐Pipe Robot to Travel Through Complex Winding Pathways in Three Dimensions
ABSTRACT This paper presents a V‐shaped gas pipeline inspection robot which achieves high roll rotation performance, out‐of‐plane double elbow travel performance, and inverted siphon adaptability at high speed without requiring complicated manual operation. The principle for traveling through the out‐of‐plane double elbow was theoretically demonstrated
