Design and construction of an in-pipe robot for inspection and maintenance

摘要

Inspection and maintenance of aging pipelines is crucial to the reliable and continued distribution of hydrocarbons. In this paper, we describe the design and construction of a robotic platform for inspection and minor maintenance of pipelines. The 7.5 kg robotic platform was demonstrated to move straight inside 12″ to 16″ diameter pipes in a forward or backward direction, and either horizontally or vertically. The experimental robotic platform has three sets of two wheels, and three driving motors. The equations governing the mechanical frame's component sizes are presented and the robotic frame component dimensions derived. The paper also discusses the construction and testing of the robot. Future work includes adding sensors, controls for turning, a microcontroller board, and a robotic arm for performing maintenance tasks. © 2012 IEEE.
