Abstract - A robot/system capable of operating in active pipelines would be of great commercial and industrial benefit. Pipe inspection is necessary to locate defects due to corrosion and wear while the pipe is transporting fluids. Because pipelines are typically buried underground, they are in contact with the soil and subject to corrosion, where the steel pipe wall oxidizes, and effectively reducing wall thickness. Recently many plants' pipes and drains became old and many robots to inspect these pipes were developed in the past. Inspection robots are used in many fields of industry. One application of pipe inspection system is monitoring the inside of the pipes and channels, recognizing and solving problems through the interior of pipes or channels. This paper gives a review of various methods of pipe inspection considering the advantages and disadvantages of existing systems.

In this paper an in-pipe inspection robot has designed that can deal with many kinds of pipes with various diameters (140mm-200mm.) such as plastic pipes or metallic pipes which are in horizontal or vertical manner only for 750 mm distance. The pipe inspection robot is composed of body, fore leg system, rear leg system and springs. Three legs of each leg system are arranged at an angle of 120 degrees to each other to move inside various pipe diameters. By using spring it is able to move freely inside pipes of different diameters. A CCD camera is installed on front part of the fore leg system to do visual inspection of pipe. Fig 6.
