Arduino Fights Fire With… Water?

We don’t think we’d want to trust our fire safety to a robot carrying a few ounces of water, but as a demonstration or science project, [Tinker Guru’s] firefighting robot was an entertaining answer to the question: “What do I do with that flame sensor that came in the big box of Arduino sensors I bought from China?” You can see a video of the device below.

You can see, it is a pretty standard two-wheel robot with the drive wheels to the rear and a skid plate up front. There are a flame sensor and a water pump up forward, as well. You can probably guess, the device notices a flame and rushes to squirt water on it.

That got us thinking, though. What would it take to build a real robot fireman? Turns out you don’t have to look hard to find out there are several out there already. The Thermite robot seems to have a lot of traction — in the market, that is, although its oversized treads probably give it good traction in that way, too. Most of the robots don’t carry their own water, and there’s even one — THOR — that looks like a human. Well, as much as a pie looks like a cake, anyway.

Interestingly, none seem to carry any sort of chemical fire extinguisher. Of course, we’ve seen cases where water was the best, anyway. If you want a slightly more practical home build — but only slightly — check out [Ivan’s] robot that holds a liter of water.

  1. Hehe – this is a first stage build, go back and refine, and assume that the source of the flame doesn’t put itself under the dribble. Hint, use a wash / spray bottle to get a larger area.

  2. The idea is fun but why not put a 5 minute effort on writing a code that reverses the robot a bit before releasing water. Or maybe use 2 seconds to cut the straw shorter so that the fire doesn´t need to move…

    It´s all in the details. This robot could have been cool but cheating by moving the fire makes this device look very bad and amateur.
