A group of researchers at Beijing University of Civil Engineering and Architecture have developed a multi-mode snake robot that promises to transform pipeline inspection and how critical industries maintain and secure their subway infrastructures.
This new robot, designed to inspect the inside of large-diameter large-diameter pipesThe new robot, designed to inspect inside large-diameter pipes, uses helical and meandering motions to navigate through confined spaces, far exceeding the capabilities of traditional robots. traditional robots. Its ability to meticulously adhere to pipe walls and provide detailed inspection is due to its modular structure composed of multiple interconnected segments that mimic the movement of a snake.
Each segment is equipped with its own set of sensors and cameras, allowing 360-degree coverage during inspection. The study highlights that the robot significantly improves on existing methods, which often fail to identify small cracks and leaks.
How was the snake robot developed?
The scientists used advanced modeling and simulation techniques to develop the algorithms that allow the robot to adapt its movements in real time to changes in the pipeline environment.
The research was carried out in close collaboration with robotics and materials experts, ensuring that each component of the robot can withstand the extreme conditions inside industrial pipelines. This interdisciplinary work was essential to achieve a design that is functional and highly efficient in terms of energy and maneuverability.
The full study on the development and capabilities of the snake robot was published in the journal Biomimetic Intelligence and Roboticswhere the technological advances and field tests are detailed. The following video shows how this robot moves.

Benefits and applications
The oil and gas, water and wastewaterThe oil and gas, water and wastewater industries will find this robot a valuable tool. This robot not only reduces operating costs, but also increases efficiency and safety in inspections. Furthermore, its use could be extended to other applications, such as pipeline exploration in complex urban environments and environmental monitoring.
Initial experiments showed that the robot can operate effectively in pipes up to 500 mm in diameter, adjusting its movements in real time to adapt to various environments. The researchers anticipate that future versions may incorporate self-repairing crack repair and sediment cleaning capabilities, further expanding its applications.
