A flock will be auto-swept across the city and the drone will travel around. These robots will be able to repair the cracks on the road and pavements before they are made. To repair the road in a minute, the 3D printer ribbons can spray it in, the report said Mirror.
Experts say that automobile traffic in cities and drones can be run at night. It is believed that traffic and road networks will be delayed.
Professor Mark Myodonic of the University College London said that Leeds City Council has worked with an engineer and design team to implement the "Automatic repair city" plan.
He told the Schlittenham Science Festival that the UK network of street networks is being damaged due to lack of repair and preventive measures.
"We think we want to see them when there is a small crack in the street - the drones flying all around the street can see them and another drone will land there and it will be repaired," said Myodonic.
"You can stop the traffic at four in the morning, for a minute."
"This is a different problem for the highway, but for Sheltonham and the big cities, I think the use of auto-on night will not have any effect on the traffic," he added.
The same technology can be used in the construction industry, according to the Myodonic.
