Working with the University of Warwick, UK civil engineering firm Belvoir Rail has acquired two quadruped robots to see if they can be used for rail inspections.

The partners will investigate how the Unitree Go2s smart, bionic quadruped robots can be enhanced to so they can carry out rail inspections.

The robots come from Chinese firm Unitree Robotics (www.unitree.com) and this is the first delivery of these models to the UK. The aim is to make inspections more reliable and redefine operational standards and proactive maintenance strategies.

Equipped with 4D lidar technology, the Go2s boast omnidirectional 360˚ perception, coupled with agility thanks to multiple knee joint motors.

Belvoir Rail wants to elevate the safety, efficiency and productivity of rail inspection and maintenance teams. The incorporation of robots into the inspection process could have numerous advantages, especially in complex and challenging environments.

Safety has always been a priority in inspection work, and the introduction of robotic technology could reduce risks to human inspectors. Capable of operating in hazardous environments, these robots are paving the way for safer inspection practices.

The continuous round-the-clock monitoring capability ensures maintenance issues are promptly identified, preventing potential failures and breakdowns. This level of flexibility translates into more streamlined and effective operations for inspection teams.

Equipped with an array of sensors and cameras, these robots can collect data, providing detailed information on equipment and infrastructure conditions. Temperature readings, vibration analysis and visual inspections are examples of the information they could provide.

The robots’ adaptability allows tailoring to inspection requirements, changing day-to-day tasks. They offer an efficient method for repetitive and time-consuming processes. Remote operation provides flexibility, letting inspectors control and monitor inspections from a safe location. This is particularly beneficial in situations where physical presence might not be practical or where the work environment may be dangerous.

Their versatility opens possibilities for inspection processes, from maintenance planning to tracking the history of equipment conditions over time. They can be equipped with tools and sensors based on the requirements of the inspection task, making them suitable for a wide range of applications.

An advantage of incorporating robotics into the inspection process is their ability to operate in complex environments. Their ability to move through tight spaces and access difficult areas redefine what’s possible in inspections making them valuable in operational or depot environments.

Beyond their technical capabilities, this AI enabled robotic technology presents a human-centric approach to inspection work with the ability to learn continuously. By handling repetitive tasks, they allow human inspectors to focus on more complex aspects of their roles.

Belvoir Rail (belvoir-rail.com) provides products and services that help railways improve performance. It is working with Warwick Manufacturing Group (WMG) at the University of Warwick (warwick.ac.uk) to improve the performance of the robots.
