Snake-like robot with tentacles set to transform offshore subsea jobs

A new underwater robot with a soft, tentacle-like arm has been developed by the UK’s National Robotarium in collaboration with Brazil’s Senai Cimatec, aiming to revolutionize offshore subsea inspections and maintenance. Measuring 3.3 feet (one meter) long, the robot’s flexible design allows it to bend and conform to complex underwater structures, enhancing safety and efficiency compared to traditional rigid robotic arms. Equipped with sensors to track its shape and position, the robot can perform precise inspection tasks near subsea infrastructure such as wind farms and pipelines, even in turbulent water conditions. Tested successfully in harsh environments at the National Robotarium’s wave tank, the robot demonstrated stability under forces up to 300 g and the ability to quickly regain its position after disturbances. This adaptability makes it suitable for deployment from underwater vehicles, potentially reducing reliance on divers and large vessels, thereby lowering safety risks, costs, and environmental impacts. The project underscores the importance of international collaboration, with both UK and Brazilian teams
