  • Design of a wheeled-Type In-Pipe Inspection Robot to overcome motion singularity in curved pipes
    Rajendran Sugin Elankavi, D. Dinakaran, Arockia Selvakumar Arockia Doss, R.M. Kuppan Chetty, M.M. Ramya
    Journal of Ambient Intelligence and Smart Environments, 2024
    This paper discusses the development and design of two wheeled-type In-Pipe Inspection Robots (IPIRs), Kuzhali I and Kuzhali II, which were created to address the limitations of traditional human inspection methods and earlier robot designs. Specifically, the robots aim to overcome the motion singularity experienced by IPIRs when navigating through curved pipes. Kuzhali I was developed with wheels mounted at an asymmetric angle, which enables the wheels to maintain contact with the pipe’s surface, preventing motion singularity. However, Kuzhali I had limitations due to its prismatic mechanism, and thus Kuzhali II was developed with a telescopic mechanism to allow it to pass through vertical pipes with obstacles. Motion analysis was conducted on both robots to demonstrate how they overcome motion singularity and navigate through straight and curved pipelines. Simulation results showed that the forces acting on the robots’ wheels fell within 5 N to 12 N, demonstrating stability while navigating pipeline junctions. Experimental tests were conducted on Kuzhali II, and the results were compared to simulation results, showing an error of less than 5%. The results of the experiments indicate that Kuzhali II is safe to use for pipeline inspection, can navigate through vertical pipelines with ease and can overcome motion singularity in curved pipes. These robots offer a faster, more accurate, and safer alternative to human inspection, which can reduce the risk of pipeline failures and associated environmental and safety hazards.

    International Journal of Mechanical Engineering and Robotics Research, 2022
    —Research in In-Pipe Inspection Robots (IPIRs) has gained interest over recent years. Pipeline inspection robots bring reliability and repeatability to various pipeline inspection and maintenance processes. IPIRs are categorized based on their type of locomotion, and this study aims to analyze their advantages and limitations. Among all the IPIRs, the wheeled type IPIR has seen a tremendous change in its design, steering mechanism, and the way they use different wheels to pass through pipelines easily. This study compares and analyses an up-to-date review on wheeled type IPIRs in detail. This review helps the researchers to select the optimal wheeled type IPIR for inspection. The review concludes with the future research directions that the researchers need to focus on for the development of pipeline inspection robots. Developing an effective IPIR ensures human safety and improves the inspection process.
  • Design and Motion Planning of a Wheeled Type Pipeline Inspection Robot
    Rajendran Sugin Elankavi, D. Dinakaran, Arockia Selvakumar Arockia Doss, R.M. Kuppan Chetty, M.M. Ramya
    Journal of Robotics and Control Jrc, 2022
    The most popular method for transporting fluids, and gases is through pipelines. For them to work correctly, regular inspection is necessary. Humans must enter potentially dangerous environments to inspect pipelines. As a result, pipeline robots came into existence. These robots aid in pipeline inspection, protecting numerous people from harm. Despite numerous improvements, pipeline robots still have several limitations. This paper presents the design and motion planning of a wheeled type pipeline inspection robot that can inspect pipelines having an inner diameter between 250 mm to 350 mm. The traditional wheeled robot design has three wheels fixed symmetrically at a 120° angle apart from each other. When maneuvering through a curved pipeline, this robot encounters motion singularity. The proposed robot fixes the wheels at different angles to address this issue, allowing the robot to stay in constant contact with the pipe's surface. Motion analysis is done for the proposed and existing robot design to study their behavior inside the pipeline. The result shows that the proposed robot avoids motion singularity and improves mobility inside pipelines. 3d printing technology aids in the development of the proposed robot. The experimental tests on the developed robot inside a 300 mm-diameter straight and curved pipeline show that the robot avoids motion singularity.
  • The Development of Ultrasonic C-Scan for Ferrous Wall Surface using the Climbing Robot
    Jaise Jose, Rajendran Sugin Elankavi, D. Dinakaran, M.M. Ramya, R M. Kuppan Chetty
    7th International Conference on Communication and Electronics Systems Icces 2022 Proceedings, 2022
    This paper describes the use of a wall-climbing robot for performing the ultrasonic C-Scan of the vertical surface. The robot utilizes permanent magnetic adhesion and can climb the ferrous surface to inspect the ferrous infrastructures like oil tanks. With the wheeled locomotion, encoders in the wheel can be used for locating the robot on the vertical surface. A specially designed housing is fabricated for the robot to hold a 2 MHz probe to perform the ultrasonic testing of the surface that is climbed. The probe holder movement is controlled through a motorized belt drive, enabling the probe to establish contact with the surface and retract. This paper details how the C-Scan is built using the position and A-Scan data thus obtained. Each scan data is processed individually using the MATLAB signal analyzer. It is evident from the results that the defect has a different frequency reflection and is visible from the C-Scan developed. The final C-Scan image was checked by superimposing on with the test surface and the defect was found to agree with the obtained scan image.

    Pipelines are crucial in transportation, requiring regular maintenance to function correctly. Robots perform maintenance works, and each robot moves through the pipes using a different mechanism. The In-Pipe Inspection robots are categorized based on their locomotion types. The mechanisms utilized by wheeled wall-pressed type In-Pipe Inspection Robots are divided into dependent and independent mechanisms. The present wheeled IPIR using the dependent mechanism finds difficulty in passing through vertical pipe with obstacles. In this study, one robot from each mechanism is chosen, and the mobility of that robot inside a vertical pipe with an obstacle is examined through simulation using the MSC ADAMS software and observed experimentally. The results show that the robot wheels used in the independent mechanism always make contact with the pipeline's inner surface compared to the dependent mechanism. This result indicates that the robot with the independent mechanism is more suitable for In-Pipe inspection.

    The chemical, oil and windmill plants use pipelines for transportation, mainly carbon steel. The pipelines are examined by human personnel, which is unsafe and leads to many accidents. The solution for these problems is inspection robots which can be used extensively for pipeline inspection. They can perform the task of analyzing the damage or defects that occur over the pipelines. In this project, we have designed and developed a robot which can crawl and traverse along the pipeline externally. A 3D model of the robot is made and exported to the ADAMS package for dynamic analysis. The results show that for the robot to move along the pipeline, a force of a bout 100 N and a dynamic torque of 5 N are required. A magnetic analysis was performed to select the wheel that could produce 60 N of force for a single pair. This analysis was carried out using the FEMM package and from the results obtained, an N35 magnet with a radius of 50 mm was selected. The hardware and components for a 400 mm diameter pipeline were chosen based on simulation results, and the results obtained are up to 85% in agreement with simulation results. The proposed robot was fabricated, and it was found that it could carry a load of 8 Kg while moving over a vertical pipe.

    This paper presents a modular design of a wheeled wall-press type In-pipe Inspection Robot using 3D printing technology. The proposed robot (Kuzhali) consists of a prismatic joint to which the modular parts are attached. This mechanism ensures that the wheels are in contact with the pipe's internal surface. Finite Element Analysis (FEA) was performed on the custom-designed parts to see whether they can withstand the stress acting on them while passing through straight and curved pipelines. The analysis was carried out for curved pipes with a Factor of Safety of 1.5. To optimize the performance and durability of the robotic legs, the thickness of the components are modified. The design of the components was validated with an error of ± 5 %. The new design was fabricated and it was found that the proposed robot was able to move through straight, curved and L-branch pipes in the horizontal plane.

    Jaise Jose, R. Sugin Elankavi, D. Dinakaran, RM. Kuppan Chetty, M.M. Ramya
    Proceedings of the 3rd International Conference on Intelligent Sustainable Systems Iciss 2020, 2020
    In this paper, an adhesion system used for magnetic wall climbing robots using permanent magnets is examined for its change in adhesion concerning the inter-magnet distance within the Yoke. Pocket milled ferrous material of high permeability named yoke is used to hold neodymium magnets in mobile wall-climbing robots. For a climbing robot, the self-weight is a significant parameter which needs to be at the minimum possible value. This simulation study is expected to help in bringing down the weight of the yoke holding magnets and help in finding the right inter magnet distance for the magnets used. Simulation studies were carried out for various inter magnet distances and the values are reported. An optimized distance was arrived using the simulation results thus obtained.
