Robot Firefighter To Throw Extinguisher Grenades 78

S810 writes "Discovery News is running an article about the U.S. Navy developing a robot capable of 'throwing extinguisher grenades.' From the article: 'SAFFiR would need finger and hand coordination to wrestle fire hoses into place or accurately throw extinguisher grenades. It similarly would need the sure-footed balance of a veteran sailor's sea legs to confidently walk the wave-tossed decks of warships. An infrared camera could allow such a robot to see through smoke-filled hallways, and perhaps it could detect the location of fires through gas sensors. The robot's battery is intended to pack enough energy for half an hour of firefighting action.'"

    I want to see a warship manned with robots like that. Can you imagine how intimidating that would be, to see that in your scope? Send up the periscope, and all these robot heads swivel around to look directly at you.

      Not really. It just means fewer concerns over the loss of human lives if you sink the ship (shouldn't be too hard if you are already within periscope distance).

      It's only intimidating to people on-board who are being attacked by the robots (e.g. if some crazy nut has is using them to kill/hurt people on board).

      Maybe there's a good reason, but I haven't been able to figure out why you wouldn't just use a little mortar tube for the grenade part. Like a potato gun without the pyro.

      Store a compressed air tank, bypass the complicated hand and arm movements, and skip the power requirements for that part... no?

        Watch some of the "Forrestal fire" videos where responding seaman are blown away and incinerated to see why the Navy is interested. Likewise, you could seal a compartment with a robot inside while it continued to fight a fire which would suffocate a human crew.

        Dunno... The amount of water going through a firefighting hose operating at 100PSI has more than enough mass flow to power a turbine which could keep a robot going easily. That would knock out the half-hour problem. Of course this would require a hose coupling directly to such a robot.

        The joke is on you. This "fighting fires" with grenades sounds too good to be true. The real end goal is more likely to be about dropping robots behind enemy lines and have them throw grenades which are meant to kill people. In that regard, having the battery explode releasing toxic chemicals everywhere may just be icing on the cake for its original designers.

      Compare to the auto-belay devices on many climbing walls. A couple of falls, the second fatal, got a worldwide recall of the most popular brand. They've been redesigned to get rid of the fault and they're back, but they will wear out with age. But even before the recall, they were (according to climber friends) statistically more reliable than a human holding a rope.

      So basically, they recalled a safety device that was more safe than a human, and replaced it with humans holding ropes, all in the name of safety.

    OK, I admit I have zero experience with fighting fires on ships ... But wouldn't you want a larger battery life in case it's a stubborn fire?

    I would think the last thing you'd want is all of the robots winding down just before the fire is out.

      The simple solution would be to not send out all robots. If a fire breaks out in the mess hall you don't send 20 robots there to fight it. You send 5 first, maybe another 5 after 10 minutes, another 5 10 minutes later, etc. By the time you send the last wave the first couple waves are already back recharging (or getting their batteries replaced with fresh ones).

    It's all well and good to have an automated firefighter unit, but doesn't it make more sense to simply have better systems that are more passive?

    Couldn't you just have a robotic arm that's tied into the flame retardant system attached to the ceiling in important or dangerous rooms? Make it smart enough to detect fire, take aim, and spray it with a flame retardant. I'm sort of imagining the robot in the recent Iron Man films that does something similar. Seems like that could be done without the need for battery packs and ambulation, and not only would it be more ubiquitous, it'd be able to respond a hell of a lot faster than something that's traveling on foot throughout the ship, which would mean less time for the fire to cause damage.

    Granted, you can't just drop the sort of thing I'm talking about into a ship, since you'd need to pipe flame retardant into a few places it isn't already, but the cost of one of these ambulatory robotic firefighters has got to be ridiculous (assuming the R&D pans out anytime soon), so I wonder at what point it's more cost effective to just do something simpler with technology that we already have.

    • Or we could use regular "dumb" sprinklers at a tiny fraction of the cost of automated robot arms and "smart" sensors in each compartment. Anything that renders these inoperative would have done in a "smart" robotic arm sprinkler already.

      • That thought occurred to me immediately after making the post. >_

        I think the benefit of an arm would be the ability to direct a more concentrated flow at something specific, but, as you pointed out, things that would render dumb sprinklers useless would likely render these smart ones useless as well, and the dumb ones cost significantly less.

    • I'm pretty sure that Navy ships have lots of passive firefighting features already.

      Fire in the confined spaces of a warship is a truly terrifying prospect, and the Navy is always looking for the latest in fire suppression technology.

        Former Navy sailor and a former #1 nozzleman here. You can't possibly have enough robots to fight fires in all the places a fire could be unless you make the ship a giant firefighting robot. As cool as that sounds, it kind of detracts from the actual mission, which is to fight and win wars at sea. The ship's crew are ultimately much better equipped to defeat fires than some automaton because they have native human intelligence and can use spur of the moment logic to reassess a situation. A robot might see a hotspot in a puddle of burning fuel oil and concentrate on it, where a human would say "that'll put itself out and I need to concentrate on this jet of flame erupting from the gas turbine engine." Someday, maybe, robots will be able to assess a main space casualty the way a human could, but until that day comes the Navy should continue to rely on the very good judgement of its human firefighting teams. The US Navy trains every single sailor to be a firefighter, the way the Marines and Army train everyone to be a rifleman. Damage control is a religion among the seagoing set. It will be a very long time before a robot can replace a motivated sailor as the best means to save the ship. There are too many variables to leave it to code.

    As a former volunteer firefighter if my old team gets a hold of anything that throws any kind of grenade, then no one will be able to light up a cigarette in the privacy of their own home without worrying about a fire grenade coming through the window.

    On a practical level the fire robot would have to be able to squeeze through narrow spaces, over furniture, and around debris. I can't think of many household fires I was in where a robot would have been much help. It would have fallen through the floor at a kitchen fire that burned through the floorboards, we had to crawl across the couch to get to the hallway. I can't see how a robot could do that. Not only would it have to manage stairs, it would have to be able to bound up stairs dragging a hose line.

    There's also deployment time. When the truck rolls up to a scene, we're ready to go in a few seconds after our boots hit the ground. I don't know how you could unpack a robot, boot it up and get it to the structure any faster than the entry and back up teams could pull the pre-connects.
