It can move 1 meter per second and use its computer vision system to rapidly acquire rough 2D images of every inch of that tunnels walls. It has a small unmanned vehicle with a crane mounted on top of it.on top of the crane is a robotic arm to help fix the cracks.
They say this 3 year project will have more safety and also helps the inspectors. The Robot also will be shorter tunnel-inspection closure times, and financial savings as less human workers will need to be paid, and for less hours. it will be expected to be ready by next year and will be tested in London, experimental tunnels in Switzerland, three underground stretches of the Egnatia highway in Greece.
