Autonomous drones are advancing firefighting efforts

The market growth for autonomous firefighting drones is on a rapid rise in 2023 and we could soon see devices put to use in both natural and domestic emergencies.

As the climate crisis ignites blazes of increasing severity and regularity across the planet, emergency services will inevitably become stretched.

Like the vast majority of industries, technology will be used to compensate for any disparity between demand and available manpower โ€“ the very worst of which could be felt by the emergency services.

With wildfires engulfing vast regions of southern Europe and Canada in the present, however, novel technological ideas and concepts may have to fill gaps faster than previously expected.

Chief among these is the autonomous firefighting drone; the market growth of which has grown by over 15% in 2023 alone. Several prototypes have been popping up across some 30 countries with China responsible for 11% of the market, and the US and Europe comprising roughly a third.

An impressive video is making the rounds on social media at the moment, showing three drones completing a staged fire-drill in a high-rise building at a secure site in Beijing.

Attached to flailing water hoses at their bellies, the drones methodically extinguish the multi-story fire using integrated water and foam jets in around a minute.

The test was the latest in a handful of successes dating back to 2020 for Chinese company Routen, and the expectation is that its carbon fibre robot may soon be green-lit for real residential emergencies.

Elsewhere, Portugal are testing their own drones specifically for preventing wildfires before they spiral out of control in densely wooded areas.

Developed at the University of Coimbra, โ€˜Sapโ€™ is 21kg and has a wingspan of 2.14 meters. Designed to reach areas too treacherous or remote for humans, mechanical engineer Carlos Viegas described the device as the โ€˜future of firefighting.โ€™

Also interested in the potential of employing robotics for emergencies, the UK is aiming to use drone technology for a different purpose. Instead of having a water hose attached like the previous two, FireDrone opts for maximum manoeuvrability, in that itโ€™s small and completely heat-resistant.

The durable, basic design is intended to protect a ton of sophisticated sensor equipment concealed inside, so crucial data can be relayed back to firefighters from inside low visibility danger zones.

Paired with wearable AI smart helmets undergoing trials in Scotland, the approach to firefighting could soon be completely overhauled using technology.

Though weโ€™re not always keen on the idea of technology exploding onto the scene, when it comes to matters of life and death, no expense should be spared.
