Development of In-pipe Inspection Robot

Abstract

An in-pipe inspection robots are designed to remove the labour force and to act in inaccessible environment. In this paper we present a comprehensive study of in-pipe inspection robot. After some period every pipeline requires inspection and maintenance to ensure their safety and integrity. So, in-pipe inspection robots are used to inspect varies pipeline elements such as straight pipelines, elbow and branches internally. In- pipe inspection robot inspect the pipes of various size and find the defects and obstacles in the pipes. There are many in-pipe inspection robots which are differ by their power source, steering mechanism and application. This paper also shows the comparative study of different in-pipe inspection robots. Section 6 shows the new developed steering mechanism for improvising working style of in-pipe inspection robot. Still the applications of in-pipe inspection robots are limited according to pipeline material, pipe size and working environment.
