While hose-toting drones may be a fantasy, hose-powered robo-dragons (or robotic hose-dragons — however you like it) are very much a reality. This strange but potentially useful robot from Japanese researchers could snake into the windows of burning buildings, blasting everything around it with the powerful jets of water it uses to maneuver itself. Yes, it’s a real thing: Created by Tohoku University and Hachinohe College, the DragonFireFighter was presented last month at the International Conference on Robotics and Automation. It works on the same principle your hose does when you turn it on and it starts flapping around everywhere. Essentially your hose is acting as a simple jet: the force of the water being blasted out pushes the hose itself in the opposite direction. So what if the hose had several nozzles, pointing in several directions, that could be opened and closed independently? Well, you’d have a robotic hose-dragon. And we do. The DragonFireFighter has a nozzle-covered sort of “head” and what can only be called a “neck.” The water pressure from the hose is diverted into numerous outlets on both in order to create a stable position that can be adjusted more or less at will. VIDEO It requires a bit of human intervention to go forwards, but, as you can see, several jets are pushing it that direction already, presumably at this point for stability and rigidity purposes. If the operators had a little more line to give it, it seems to me it could zoom out quite a bit farther than where it was permitted to in the video. For now it may be more effective to just direct all that water pressure into the window, but one can certainly imagine situations where something like this would be useful. DragonFireFighter was also displayed at the International Fire and Disaster Prevention Exhibition in Tokyo. One last thing. I really have to give credit where credit’s due: I couldn’t possibly outdo IEEE Spectrum’s headline, “Firefighting Robot Snake Flies on Jets of Water.”
A robotic water hose that can be used to fight fires has been developed in Japan . Researchers at Tohoku University and Hachinohe University have developed the DragonFireFighter , which was unveiled at the International Conference on Robotics and Automation . It supports itself and moves around using directional jets of water spraying from multiple nozzles at the neck of the hose . Designed for use in tackling fires , it was also demonstrated at the International Fire and Disaster Prevention Exhibition in Tokyo .
