This robotic hose-dragon could jet its way into burning buildings

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.
