This document describes a proposed wheeled pipeline inspection robot. It aims to address issues with irregular motion and loss of contact (motion singularity) that occur when conventional robots navigate curved and branched pipelines. The proposed robot features three wheels that are not fixed at 120 degree intervals, allowing the wheels to remain in contact with the pipe surface through turns. Its motion is analyzed through simulations of traveling through straight and curved pipes of varying diameters. The results show the robot can successfully navigate different pipeline scenarios and configurations to overcome limitations of previous designs.
