Researchers at Tohoku University and the National Institute of Technology at Hachinohe College in Japan have developed a snake-like robot with the body of a fire hose.

They say this new robotic system, called the Dragon Fighter, can wiggle its way into windows or other gaps in a building, carrying and directing water as it goes.

The robot fire hose powers itself by firing high-pressure jets of water downward, lifting itself off the ground. These jets, steerable nozzle modules distributed along the length of the hose, siphon water out of the high-pressure stream inside of the hose and spray it downwards.

Each module can direct itself independently, enabling the hose to weave itself through small gaps deep into a building in order to find the source of a fire.
