Automated road repairs using 3D printing could save money and reduce disruption, reports Kristina Smith
It’s the middle of the night and in the street below a team is busy carrying out repairs to the road surface. But there isn’t a human in sight.
A road-repair drone has landed at the site of a crack and a 3D asphalt printer is now busy filling in that crack. A group of traffic cone drones have positioned themselves around the repair location to protect the repair drone and divert traffic around it.
