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 most popular method for transporting fluids and gases is through pipelines nowadays. Regular inspection is necessary for the pipelines to work correctly. Humans must not enter potentially dangerous environments to inspect these pipelines. As a result of this, pipeline robots came into existence. These pipe inspection robots help in pipeline inspection, protecting numerous people from harm since human beings cannot enter the pipes and inspect them in case there is any such or kind of damage that requires repair. Despite numerous improvements, pipeline robots still have several limitations. The introduction of this in pipe inspection robots helps to solve many problems, such as leakage of the gas or fluid pipelines, rustiness, and also if the pipe is broken from any part.

“…This method is also suitable for our research. However, polyurethane materials commonly used in the sealing disc of PIGs are not directly used due to the limitations of the processing conditions [46]. Instead, urethane rubber Reoflex-30 was chosen due to its excellent stability and tensile strength.…”

Regular deformation inspection on in-service natural gas pipeline can reduce accidents caused by pipeline failure. In this study, a novel contact-testing geometry inspection gauge was proposed and its multi-jointed soft detection arm was focused study. 3D printing technology and mold casting were used to fabricated newly designed detection arm. A finite element method (FEM) was used to analyze the process of the detection arm passing through the convex defect and optimize its joint number. Then, a series compared experiments were conducted with various convex defects to evaluate the superiority on measuring performance of multi-jointed soft detection arm. The experimental results show that compared to no-jointed detection arm, the multi-jointed detection arm has a more accurate experimental value especially for defects with closer heights (8mm and 10mm) and better relatively stable in repeated experiments. This study provided options for the design of flexible caliper pig on deformation inspection in pipeline.
