Nozzle-rich firefighter is a robot, resembles dragon

Japan's engineers and technologists continue working to solve problems in handling various types of disasters—earthquakes, tsunamis, any unforeseen calamity causing extreme damage to property and human lives. This is apparent in a video that shows a research project of disaster robotics, the ImPACT-TRC Program. The Program Manager is named as Prof. Satoshi Tadokoro, Tohoku University.

Worldwide, robots are considered helpful supports where direct human intervention is risky; engineers and scientists think of others solutions.

In this quest, a recent -fighting has been introduced in prototype stage. This is the Dragon Fire Fighter, 3 meters long.

The Mainichi reported that the robot was announced on May 30, by a team including members of Tohoku University. The robot's name is apt since the robot, which is connected to a hose, resembles a dragon when in operating mode.

A video shows it injecting water into a fire in a steel drum. The robot can surpass an obstacle to directly extinguish the fire. The researchers said it took about 1 minute.

Two noteworthy features give this robot a distinctive edge in fire-fighting. It (1) can help firefighters put out hard-to-reach blazes, such as those up high, and (2) it can locate the origin of a fire using a thermal camera.

The Mainichi said it "can fly up and extinguish fires beyond obstacles in places that could be difficult for human firefighters to reach. They envisage it being used to fight fires in high-rise buildings, large warehouses and other places where it is difficult to approach the source of the blaze."

As the video shows, the robot can inject water from multiple nozzles, rising with thrusts. "Special devices with four holes each are attached to the tip and middle of the hose, ejecting water to propel the robot through the air," said The Asahi Shimbun. "High-pressure jets of water on the head of the robot and in a middle section are used to lift it off the ground," said Mainichi. The robot can be controlled remotely to seek out the source of a fire and the operator can change the direction of the robot if needed.

Tohoku University professor Satoshi Tadokoro, commented, "There have been robots in the past that go into dangerous areas in place of firefighters, but this is the first to fly over an obstacle and directly extinguish a fire."

What's next?

"Researchers envisage the robot being attached to the end of a ladder or another object, and they plan to extend its reach to about 20 meters in the future. They aim to put it to practical use within three years."

This is so typical of what I've seen of japanese research projects over the years at various conferences. Either it's very tame 'feasibility studies' (i.e. papers that go into epic length about who is at fault if approach X or Y is used)...or they totally overengineer a simple task (as in the above vid)

The most ridiculous one I've seen is when they had an entire engineer strapped into an exo-suit as a force-feedback input device (on a platform with hydraulics and all) in order to remotely move a biopsy needle by 5 cm in one axis.

I think it's easy to see that the above robot could not deliver enough water to a large amount of thrusters needed to keep many such segments in the air if the blaze is more than a few meters away from the water source

Readers of this article deserve to be informed that this is not a new way to tackle fires.
4 years ago, I have invented and patented a device which is utilizing the same principles and I believe it is doing so in a more practical and optimal way.
Patent application title is "WATER-JET HOSE MANIPULATION DEVICE".
Thank you for being fair to your audience and for respecting my intellectual property.
