BRITAIN’S road network will in the future be repaired by robots - which can fill in a pothole in a minute.

A fleet of autonomous road vehicles or drones will travel around cities identifying cracks in roads and pavements and fixing them before potholes develop.

In just one minute, a robot with an attached 3D printer will be able to spray asphalt into a crack in the road to repair it.

Experts said that in towns and cities across Britain the autonomous vehicles or drones could operate at night, meaning there would be little disruption to traffic flows or the road network.

Professor Mark Miodownik, of University College London, said Leeds City Council is working with a team of engineers and designers to pioneer the idea of “self-repairing cities”.
