“…This problem is not getting resolved even the most knowledgeable personnel is available because manually and exhaustively searching the knowledge space can be too time-consuming and labor-intensive. Quickly screening the literature, we find many studies (Lee et al 2009;Roh and Choi 2005;Sabzehmeidani et al 2010;Liu et al 2013;Ong et al 2003;Moghaddam et al 2011;Zhang and Yan 2007;Choi and Roh 2007;Lee et al 2012;Horodinca et al 2002;Jun et al 2004;Roslin et al 2012) dedicated to in-pipe inspection robot design, but very few of them, if not any, addresses the issue that we have just mentioned above. Bearing this in mind, in this study, a smart conceptual design platform has been developed to fill this gap.…”

“…The simple type caterpillar robot is characterised with a belt bound wheel connected to the actuator, which generates friction to enable the robot to move on irregular surfaces (Josep et al , 2010). The pressed wall caterpillar robot is designed for rough interior pipe surfaces such as vertical and inclined pipes with rough orientations (Moghaddam et al , 2011). The wheeless robots are comprised of straight links interconnected by motorised joints with the aim of increasing the robot’s capability to move on various terrains and surfaces, either even or uneven (Bradbeer et al , 1997; Rizkallah et al , 2016).…”

Purpose The purpose of this study is to develop a robot for non-destructive testing of the pipelines to improve its reliability and reduce the loss of products due to cracks, corrosions, etc. Design/methodology/approach In this study, an inline inspection robot was developed for crack and corrosion detection in the pipeline. The developed robot consists of ultrasonic sensors to avoid obstacles, a visual aid with high resolution to view real time images and colour sensors for corrosion detection. The Autodesk inventor software was used for the drafting and solid modelling of the robot. A dummy pipe of 500 mm diameter and 2,000 mm length with induced cracks and corrosion was fabricated to test the robot. The colour sensors placed at each side of the robot were used to detect corrosion in the dummy pipe whilst the image processing was done to analyse the crack, as well as the type and depth of corrosion present in the dummy pipe. Findings The results obtained show the ability of the developed robot to detect cracks and determine the crack growth in the pipeline in addition to its ability to determine corrosion. Practical implications Hence, the study provides a diagnostic tool for detecting pipeline defects and analysing the extent of defects to determine the fatigue rate and the useful life of the pipeline. Originality/value The novelties of this study is based on the fact that it was designed to avoid obstacles and check for cracks, leakage and corrosion in pipelines autonomously. It has visual aid that makes it possible to see the interior of the pipe. This makes it easier to identify the defect and the location of the defects before a catastrophic failure. The device is also equipped with sensors, which can detect defects and send the signal to a control system, as well as a Bluetooth device so the operator can have real time information about the state and integrity of the pipelines. The system is also integrated with a Bluetooth device, which permits its compatibility with Android and other mobile applications. Thus, the enabled user can send a command to query the state of the pipeline at any location with the feedback received in the form of short message service. Hence, this study offers contribution in the development of an independent (self-governing) system with the capability to autonomously detect defects in pipe walls and effectively communicate feedback to the authorised users. The prototype model for the evaluation of pipeline integrity will bring about a more proactive way to detect pipeline defects so that effort can be geared towards its restoration before it becomes a major problem, which will subsequently affect productivity and incur losses.

“…Caterpillar Wall-press systems are one of the most adaptive types of system in terms of shape adaptability. Tarbiat Modares University used active parallelogram adaption in a three-planed caterpillar wall-press system which could adapt from 250 mm to 350 mm, however this could be increased by altering the length of the linkages [18]. The lead screw used to alter the height of the tracks keeps all three planes extended at the same rate and hence keeps the chassis central in the pipe.…”

Abstract:The field of in-pipe robotics covers a vast and varied number of approaches to the inspection of pipelines with robots specialising in pipes ranging anywhere from 10 mm to 1200 mm in diameter. Many of these developed systems focus on overcoming in-pipe obstacles such as T-sections and elbows, as a result important aspects of exploration are treated as sub-systems, namely shape adaptability. One of the most prevalent methods of hybridised locomotion today is wall-pressing; generating traction using the encompassing pipe walls. A review of wall-pressing systems has been performed, covering the different approaches taken since their introduction. The advantages and disadvantages of these systems is discussed as well as their effectiveness in the inspection of networks with highly varying pipe diameters. When compared to unconventional in-pipe robotic techniques, traditional full-bore wall-pressing robots were found to be at a disadvantage.
