INSUBCONTINENT EXCLUSIVE:
While hose-toting drones may be a fantasy, hose-powered robo-dragons (or robotic hose-dragons — however you like it) are very much a
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 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
And we do.
The DragonFireFighter has a nozzle-coveredsort 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.
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
I really have to give credit where credit due: I couldn''t possibly outdo IEEE Spectrum headline, &Firefighting Robot Snake Flies on Jets of
