Japanese scientists made an invention new system to be closed Instead of breathing fire from its mouth, what it does exactly is fires, consisting of a sort of flying dragon that shoots water into the flames to extinguish them from above.
Details of this prototype called Dragon Firefighter (dragon firefighter), published in the magazine Frontiers in Robotics and Artificial IntelligenceIn a paper signed by scientists from Osaka University and Tohoku University.
In general terms, the design consists of a four-meter-long hose that is remotely controlled, can rise into the air thanks to its flying head, and regulates the discharge of water.
“Imagine a flying dragon that doesn’t breathe fire, but instead extinguishes it with blasts of water,” the magazine explains. Help extinguish very dangerous fires For people to get closer to the flames.
The tornado is pushed upward (flying two meters above the ground) Thanks to eight controllable water jets coming from its center and head; It can change shape and be directed towards the flames, guided by a control unit that can be operated by remote control and connected via a supply pipe to a fire truck with a 14,000-litre water tank.
nozzles They squirt water at a rate of 6.6 liters per second; There is a conventional camera and a thermal imaging camera at the end of the hose, which help locate the fire and ensure the safety of extinguishing personnel who do not need to approach the fire.
Dragon Firefighter received his baptism of fire (pun intended) at the opening ceremony of the global robot summit in Fukushima in September 2021. There, he successfully extinguished the ceremonial flame created by fireballs lit by another robot from a distance of four meters. Now it is time to develop this device industrially.
So for now This is a prototype: “We estimate that it will take about another ten years to use our robot in real firefighting scenarios,” says researcher Yuichi Ambe, adding that the main challenge will be to increase its range beyond 10 meters.
In their statement, the authors say that the journal in which the details of the project are published is open science, so experts from all over the world can freely use their plans to build their own ‘firefighter robots’ for the benefit of everyone.
