Abstract

<p>In the recent years, aged pipes are increasing, and many road collapse accidents occur. Therefore, it is necessary to inspect the condition of the pipe to efficiently determine whether a replacement or repair is necessary. However, pressure pipes that are capable of coping with complex terrains, the pipelines are complicated and are difficult to inspect with the existing inspection equipment. Therefore, based on the earthworm's peristaltic movement and artificial muscles, the authors developed a peristaltic robot in a previous research for inspecting the inside of a pressure-feeding pipe. However, owing to the unevenness its joint, the robot was unable to maneuver through the corners of a curved pipe. Therefore, in this study, we developed a high rigid joint attachment that enables the robot to pass through a curved pipe, and evaluated its effectiveness through traveling experiments by using a curved pipe.</p>
