“…In view of the non-standard construction of the tracer line, many kinds of research have been carried out to formulate specifications. It put forward requirements for the laying position and buried conditions of the tracer line [32]. (3) The electromagnetic tracer line location technologies that are suitable for small signal-to-noise ratio (SNR) situations have been developed.…”

“…In the tracer probe method, a small transmitter is placed in a non-metallic pipeline [32], which is essentially equivalent to a magnetic dipole. The position and depth of the non-metallic pipeline can be detected by constantly changing the position of the transmitter in the pipeline, and the receiver is used on the surface to track the electromagnetic signal emitted by the transmitter.…”

Buried pipelines are an essential component of the urban infrastructure of modern cities. Traditional buried pipes are mainly made of metal materials. With the development of material science and technology in recent years, non-metallic pipes, such as plastic pipes, ceramic pipes, and concrete pipes, are increasingly taking the place of pipes made from metal in various pipeline networks such as water supply, drainage, heat, industry, oil, and gas. The location technologies for the location of the buried metal pipeline have become mature, but detection and location technologies for the non-metallic pipelines are still developing. In this paper, current trends and future perspectives of detection and location of buried non-metallic pipelines are summarized. Initially, this paper reviews and analyzes electromagnetic induction technologies, electromagnetic wave technologies, and other physics-based technologies. It then focuses on acoustic detection and location technologies, and finally introduces emerging technologies. Then the technical characteristics of each detection and location method have been compared, with their strengths and weaknesses identified. The current trends and future perspectives of each buried non-metallic pipeline detection and location technology have also been defined. Finally, some suggestions for the future development of buried non-metallic pipeline detection and location technologies are provided.

“…The increase of the pressure in the pipe will lead to the increase of the robot's motion speed, which will cause wear to the pipe wall and damage to the robot itself. In this regard, Mishra et al [20] proposed a pipeline inspection robot based on the kinematics model that predicts the position of the robot in the pipeline. The robot is equipped with a variety of sensors, which are used to cross the crude oil pipeline to achieve pipeline cleaning and leakage detection, as shown in Figure 6.…”

The oil and gas pipeline will have defects such as wear, cracks, corrosion, aging and mechanical damage in the working process, which need to be detected and repaired in time. At present, there are various types of robots in the field of pipeline inspection, including wheeled robots, tracked robots, PIG robots, screw driven robots, walking robots, and inchworm robots. In this paper, the specifications, design and performance of different types of in pipe inspection robots are reviewed. Finally, a summary and prospect are made to provide a theoretical basis for the design and research of robots in this field.

“…Another type of device known as pipeline inspection gauges (PIGs) has been used in industry. Distinguished from in-pipe inspection robots with active motion controllability, PIGs are typically pushed passively by flow pressure inside liquid-or gas-filled pipelines (53)(54)(55)(56)(57)(58). Consequently, they are deficient in active motion control to undertake complex inspection tasks, notably those demanding bidirectional navigation; have limited compatibility with straight or quasi-straight pipelines; and present the risk of scraping damage against pipe walls during motion.…”

Wireless millimeter-scale robots capable of navigating through fluid-flowing tubular structures hold substantial potential for inspection, maintenance, or repair use in nuclear, industrial, and medical applications. However, prevalent reliance on external powering constrains these robots’ operational range and applicable environments. Alternatives with onboard powering must trade off size, functionality, and operation duration. Here, we propose a wireless millimeter-scale wheeled robot capable of using environmental flows to power and actuate its long-distance locomotion through complex pipelines. The flow-powering module can convert flow energy into mechanical energy, achieving an impeller speed of up to 9595 revolutions per minute, accompanied by an output power density of 11.7 watts per cubic meter and an efficiency of 33.7%. A miniature gearbox module can further transmit the converted mechanical energy into the robot’s locomotion system, allowing the robot to move against water flow at an average rate of up to 1.05 meters per second. The robot’s motion status (moving against/with flow or pausing) can be switched using an external magnetic field or an onboard mechanical regulator, contingent on different proposed control designs. In addition, we designed kirigami-based soft wheels for adaptive locomotion. The robot can move against flows of various substances within pipes featuring complex geometries and diverse materials. Solely powered by flow, the robot can transport cylindrical payloads with a diameter of up to 55% of the pipe’s diameter and carry devices such as an endoscopic camera for pipeline inspection, a wireless temperature sensor for environmental temperature monitoring, and a leak-stopper shell for infrastructure maintenance.
