But no one mentioned robots and drones, which helped the firefighters save the UNESCO World Heritage Site.

The operation involved Chinese DJI drones equipped with HD cameras. The Mavic Pro and Matrice M210 models were used to shoot on the ground.
Using the data, the firefighters determined how best to place the fire spots and drew up a firefighting strategy.

A powerful Colossus robotic fire extinguisher was also installed on the territory of the cathedral, which worked in the central nave.

Drones and robotics will also take part in the recovery efforts. Quadcopters will inspect areas where it is dangerous for people to be because of the risk of collapse. They will collect data to create a detailed 3D map of Notre Dame. The robots will also be able to assess the condition of the structure - something similar is already being used to deal with the aftermath of the Fukushima accident.
