To help them of their heroic efforts to comprise the flames, the hearth division deployed a variety of applied sciences, amongst them drones and a firefighting robotic referred to as Colossus.

The camera-equipped drones — a DJI Mavic Professional and Matrice M210 — offered the group on the bottom with invaluable close-up and real-time aerial knowledge in regards to the depth of the hearth, its place, and the way it was spreading. Thermal imaging cameras, if connected, would’ve allowed operators to see by way of the billowing smoke and determine hotspots, too.

In feedback reported by The Verge, French hearth brigade spokesman Gabriel Plus mentioned the drones performed a significant position in serving to to forestall additional injury to the cathedral.

An rising variety of hearth departments around the globe are turning to drones for such actions, partly due to their capability to be rapidly deployed, in addition to being extremely versatile and more economical than helicopters.

The ferocity of the hearth meant there was a heightened danger of heavy wood timbers falling from the cathedral’s burning attic, rising the hazard for anybody inside. With that in thoughts, the response group opted to deploy Colossus, a robotic firefighter able to tackling severe fires from inside a burning construction.

The rugged robotic was constructed by French tech agency Shark Robotics and contains a motorized water cannon that may be operated remotely. A high-definition digital camera with a 360-degree view, a 25X zoom, and thermal imaging capabilities can be a part of the bundle, giving the operator a complete view if and when the 1100-pound (500 kg) robotic must journey past the road of sight.

Whereas Colossus is admittedly a gradual mover — it may solely attain 2.2 mph (three.5 kmh) — its capability to deal with every kind of terrain makes it a useful piece of kit for the Paris Hearth Brigade and others that use it.

With some information studies suggesting Notre-Dame may have been simply half-an-hour from additional collapse, the expertise used on the cathedral on Monday demonstrated its price because it complemented the work of tons of of firefighters risking their lives to deal with the blaze.
