Rovio Fire Extinguisher


[Colt45] shows us some pictures of his Rovio fire extinguisher mod. Being a fan of model building, he built a new shell for the Rovio and mounted a halon distribution system to the top of it. He says he loaded some custom software for identifying and extinguishing flames, which he’ll upload eventually. We really wish we knew more, or at least had a video of it working. We’re a little bit surprised we haven’t seen more done with these things.

[Thanks Robert]

  1. That’s just funny as heck. “rovio” is finnish for pyre or stake.. so ‘rovio fire extinguisher’ is a bit redundant. :) (maybe it doesn’t like itself)

    cool build!

  2. “We’re a little bit surprised we haven’t seen more done with these things.”

    On the Rovio yes, it seems really hackable..the freon however I’d shy away from…

  3. Halon is similar to helium in the fact that it doesn’t react with anything in your respiratory system, it is NOT poisonous. Instead of your voice getting higher with helium, it gets lower with halon. Fun stuff!

  4. So where is the infrared array of sensors to track flames? Don’t see anything about how it tracks the candles/ knows when they are out. That will add several G’s to the build cost.

  5. I think Halon is an unfortunate choice here.
    Its effectiveness as a fire suppressing agent is directly related to how much oxygen it displaces.
    It can infact be lethal.
    But thats just because its brought the oxygen concentration below that required for both combustion and conciousness.
    A mobile robot will never be as good at this as a fixed system.
    I’d really be looking for soething more like a powder system or some sort of chemical deluge system.
    Similar to those used to protect chip pans in restaurants.
    That way it has a chance of extinguishing a small fire.
    It would be a beter robot really if it carried a hose in from a tender outside the risk area.
    Then it could deploy water or a Aequous Film Forming Foam.
    That would be usefull.
    Humans coud still do it better though.

  6. My mistake
    Halon also interupts the chemical reaction of the fire cycle.
    But I still think the robot would be unable to carry sufficent quantity for anything other than a very small fire.
