    Testers struck pieces of metal to simulate gunshots. REDOWL quickly aimed its infrared camera and laser rangefinder at the source of the noise, just as it did in tests at a Medfield gun range.

    If this is the case, this RedOwl can easily be fooled where there are multiple gunshots, especially in a battle field.

    While system could fire back at an enemy, it would be dangerous to have a weapon-toting robot that could open fire on its own. You need to have a man in the loop.

    By the time a man reacts, the sniper could have fled, or worse, fired another shot at him.
    • Sure the sniper could have fled, but I think you are forgetting that people on both sides of the battle fire guns. I'd rather not trust a robot to abstain from friendly fire.

      Furthermore I think you underestimate a sniper's reflexes; if they know the range and exact location of the enemy sniper, the enemy sniper should be worried.

      what do you perpose? that the robot fire back? too much room for error, however once the sniper has been targetted you can:
      Have the robot search in IR.
      Once the person has been spotted, the IR can keep tracking.

      If the sniper fires a second shot from the same location either he is a sniper bent on dying, or has enough support he isn't concerned with return fire.

      In regards to the robot being to slow returning fire:

      Most sniper doctrine dictates that you a) don't fire frequently, b) don't move suddenly.

      Both of those actions give a sniper away, and a spotted sniper is a dead sniper (they don't have particularly heavy armor, or the ability to rapid fire, at least not to the extent that a normal soilder does.)

      It makes a lot of sense for what we're doing in Iraq, really. If you're walking down a street in Bagdad and take fire, the first thing you do is take cover. Then you try to find out where the baddie is so you can off him. If your killer romba has found him, it just saves you the time of looking.

      As to being fooled, it probably wouldn't be to hard to have it track multiple targets. Navy ships have radars that can track 300+ at once. Well enough to put AA missiles on any of them at a word.

        About two years ago I saw a show that was showing off a new anti sniper tech. It was a very high speed digital camera attached to a computer. It actually looked for bullets, flying through the air. When it found one, it would trace the trajectory, usually seeing the bullet 3-6 times in all, and plot a reverse course which in theory should cross through the point of origin. (the gun)

        There was no weaponry attached, it was merely a computer screen to show the bullets as captured, overlaid on the live view, along with drawing a line showing reverse trajectory. The men in the field still had to interperet it and spot the sniper and deal with him.

        I assume this is the next step of evolution of the system I saw back then. Should have been sufficiently technologically challenging, though I suppose if you could get a more 3-d idea of where the bulllets were, (which would be possible with two cameras I suppose) then use laser rangefinding to calculate distance as you sweep across the reverse trajectory, you should be able to calculate how far away the bullet is from you at any given point in the sweep, and when that number intersects with the laser range finder's distance reading, unless you have crossed an obstacle, there's your target. Actually I suppose it would need an exact match, because if the LRF was showing several feet shorter distance, then you're probably passing an obstacle that's between you and the course of the bullet. It's probably using some variation on that simple idea.

        So we don't quite have a defense drone a la Aliens, but it's not a bad idea for somewhere that you are expecting trouble.

        Problem with snipers is, if they are halfway decent, after the first shot they've already won and it's not going to help much to shoot back.

        REALLY cool would be a gun that shoots lead slugs (like safety slugs, lightly jacketed powered lead) and could take bullets out of the air, Patriot Missile style. That's probably more than a few years out though.

      In reality encouraging snipers to run away is still going to be a win on the battlefield. Presumably most snipers hole up in a reasonably secure, hidden vantage point and remain there. If a technology makes that unfeasible then you've gone a long way to decreasing their effectiveness as their initial tactical advantage is neutralised on their first shot. A sniper who's legging it isn't shooting at you and if you have a camera automatically pointing in his direction then tracking him is a possibility.

        Negative. Snipers do NOT fire from the same location. Now, a sharpshooter might if they're in a fortified location (like in an urban setting) but a sniper out in the wild gets their behind out of the area once they've taken their shot.

        Take a gander at the book 'Marine Sniper' some time. It's the story of Carlos Hathcock in Vietnam. There's some pretty amazing tales in there. I'll give one great example.

        He was dropped off to take care of a Vietnamese offical in one of his toughest jobs. He knew it was nuts, but took it because if he didn't he knew they'd get some other guy to do it that wasn't as good as him, and the guy would probably die.

        The building where the official would be dropped off was about, IIRC, 2800 meters away from the tree line. It was just a big field after that with tall grass. Hathcock knew he'd only have one shot at this, so he had to get in close -- which for him was 800 meters. He spent about 2 days straight crawling through the weeds out there between the tree line to a depression in the field where he could take his shot and then get out parallel to the way he came in and then await extraction.

        He took his shot, saw it was a definate hit and then "booked" outta there.. it took him hours and hours to crawl out of there on his belly. You don't just get up and start running, you still have to maintain stealth.

        It depends on what you mean by "win." You see, for the case in Iraq at the moment their fighters are culturally influenced by Asian and Steppe fighting methods (the history of this stems from Sun Tzu and other cultural writings being moved along the Silk Road and also from Mongol invasions) which posits that running away is in fact winning in their mindset. The western mindset, which you so eloquently put in your example of winning, is about fighting the enemy in a decisive battle and if the enemy runs that is a "win" in our mindset. So at a tactical level our western mindset might see it as a win but for the enemy it is part of a longer term strategic culture that champions running away to fight again another day.

      I few years ago I think one of the Discovery channels had something on an optical bullet tracker, I'm not sure if it was from Trex or not. Basically, it took advantage of the fact that bullets move much faster than anything in their vicinity, so the only major differences between successive images from a high-speed digital camera would most likely be the bullets. They had a cool demo system where the camera was pointing at a shooting gun in the distance, and it was highlighting the trajectories of the bullets it detected on a computer screen, with all of the lines converging on the gun. Couple this optical system with acoustic triangulation, and you have the best of both systems: zero in the camera quickly on the general source of the shots using sound, then pin-point the exact source of the bullets optically. Eventually this system could be made compact enough to fit on top of a rifle like a digital scope.

    Step 2, get a single-shot gun on that puppy, and let a local controller make the decision on whether or not the bot can take the shot from a short distance. Have a soldier then reload the shot, and repeat.

    Step 3, have a single controller controlling a small set of turrets, each have many bullets, but a very limited firing rate, and low-calibre. These are mostly used for guarding, but can auto-locate and prioritise potential targets for highlight to the user as they appear. Guards are replaced. A speaker system will warn long before any shots are taken, and will require keyed permission before any weapon may be fired.

    Step 4, fully-automatic, mobile turrets with extremely basic quasi-AI. Simple patrol routines, many bots to a controller, controller is given the highest priority input at any given time, though each device still requires digital oversight before a weapon may be fired. Speaker and microphone system allows basic use in social settings. Simple anti-theft devices are unsuccessfully installed to prevent black market aquisition.

    Step 5, regular quasi-infantry replacement. Still no regular AI, but simple stair-climbing and object manipulator add-on components allow regular use of this cheap, modular little turret. Increases patrol coverage ability of the reduced-size army, and is used even in the most quiet occupied zones. Emits teargass or similar irritant if not opened correctly, and each device has a fairly unique set of openning steps. Becomes the common fictionalized face of the modern army.

    Step 6, increased use and acceptance of such tools allow isolated private use of non-lethal mobile turrets. Wars and occupations that used to be implausible even today are actively considered. AI is still considered taboo on these units, but they do get more advanced quasi-AI never-lethal automatic modes with simple yet elegant rule sets for more situations.

    Step 7, news reports of incidents and possible tragedies involving these units no longer phase much ofthe occupying nation's citizens. All controlled-weapon-robotic activity are redundantly monitored, and the guilty are regularly punished - the system is widely trusted and highly valued. Simple social-use AI robots gain a small level of utility (rather than entertainment), and limited acceptance. The solar system has a wide array of weak-AI devices, both public and private, on each planetoid. The use of humans in the army is mostly that of tactical oversight of unmanned weapon platforms of many types.

    Will the end result be a good thing... can't tell. But something like this progression seems innevitable given existing technology, and the needs of both our economy and the perception of our military circumstances.

  • Wow, a robot that detects snipers after they've fired their first shot.

    Maybe they could use this technology in other applications, like detecting suicide bombers from the sound of the blasting cap that sets off the dynamite. Or maybe a robot that catches serial killers by counting the victims -- once they reach eight it sets off an alarm.

  • Maybe they could just merge the roomba and the Sniper bot and create the "iSoomba", a sniper robot that efficiently cleans up the dead body when it's done killing!
  • A poster above mentioned the possibility of a .50 caliber rifle shooting through a wall. But brute force aside, what about the extremely long range of these sniper rifles? Even with a high-zoom camera I doubt that the robot would catch the puff of smoke from one of these monsters 2,000 meters away:

    Mind you, these rifles won't just kill people at that range, but they'll punch holes through armor or engine blocks in vehicles and aircraft from that distance. Talk

    In the article they mention that the machine can illuminate the target and can work on a mobile platform or can be mounted.

    It would seem to me that this would be excellent to have either moving with troops and/or mounted around the barracks in an urban area. If someone takes a shot at you, the sniper is lit with a spotlight which a) prevents them from seeing very well, and b) lets everyone and their dog know where the shot came from. This would be quite useful.

    Yes, there are problems, but I'd be interested to see how it worked out.

    The holy grail, of course, would be a system which puts a bullet in the head of anyone who takes a shot at you, but that's just not going to happen - way too many unsolvable problems.

    Even a system that put a tranq dart or something like that would be very hard to do properly - it's not the tranq dart that's the hard part so much as the problem that your troops might not be able to fire at something, or that a handyman would hammer in something at just the wrong pitch[1].

    Just using sound won't do it for detection. Silicing is possible if you keep your bullet from moving more than ~1100fps, and long range accurate fire is still possible with that muzzel velocity if the ballistic coefficient is high enough (think sptitzer/boattail .308 around 275 grains). Even if you stay wtih "standard" ammo, you can alter the sound of it using "silencer" technology, to the point where it isn't really recognizeable as a gunshot.
    • If you force all snipers to use special equipment you eliminate most of them.
    • 1100 fps is slow. Army snipers are using 300 Win Mags at 2800+ fps with a 200 gr bullet. Then think about the Barrett 50 shooting a 400 gr slug at 3500+ fps. That gives you enough time to duck out of sight on a 1000+ yd shot. The idea of the sniper round is extreme accuracy and a flat trajectory. This is only obtained by speed and bullet design. 1100 fps is a 12 ga shotgun with target loads, (Win AA 1 oz #9 shot). I reload my 357 Mag with 140 gr hollow points at 850 fps.

      The perps aren't sniping anymore, they're blowing themselves apart with dynamite.

      I'd have thought this would be modded +5 Funny, because it is. But maybe people seriously think that the military no longer needs to deal with snipers. Unfortunately, the presence of suicide bombers does not negate the presence of snipers, and that Iraq is not the only place the US military finds itself these days.

    I used to be in the US Marines and was trained as a Designated Marksman, which is an urban sniper, and worked with many of the Scout-Snipers which are the "classic" snipers.

    My first comment is that a good sniper can hit someone at ~1500 meters with a .50 caliber rifle (A.K.A. Special Application Sniper Rifle (SASR)). This means 5 seconds until the sound is heard and means the sniper can get a decent head start running away, if they want, which they probably don't or they can just stand up, wave, and be happy they are outside the range of any weapon their target is carrying. This is assuming they don't fire from the crest of a hill and slowly back down off of it removing themselves from any danger of direct-fired weapons. Yes, indirect fire is still a problem, but it has always been a problem. If you know where the sniper is, you can always call for mortar or artillery fire. However, this is hardly cost effective, and even calling in a strike on their position does not guarantee a kill - especially if they choose their location wisely.

    Second, snipers are some of the sneakiest people I have ever met. If you tell them there is a robot that will respond to the noise they make, they will just set up a booby trap a hundred meters away and have their spotter trigger it at the same time they shoot. (Snipers always work in teams.) There is no way the robot is going to hear a bullet fired when it is being over-loaded by the sound of 2 pounds of C4 being detonated. If the snipers find out that it can still hear them, they will daisy chain a couple of claymore mines together with some det cord just to make things more confusing.

    Finally, on a sort-of-related-but-side note, I have seen bullets fly through the air and it is pretty cool. When standing behind a shooter, just focus on the air about half-way to their target. After a few shots, your eye will start focusing on the bullet.

    The mood of the average person in the U.S. now is that they are willing to pay to kill. They area willing to pay an endless amount of money for killing, but very little for making relationships.

    It's all part of the thinking of the Military-Industrial Complex: If you disagree with someone, just kill them.

    Supreme Commander of Allied Forces in World War Two and former U.S. President General Dwight D. Eisenhower said in a famous speech [yale.edu] that we should beware of the "military-industrial complex". Here's a quote:

    "In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military-industrial complex. The potential for the disastrous rise of misplaced power exists and will persist.

    "We must never let the weight of this combination endanger our liberties or democratic processes."

    Another quote:

    "The prospect of domination of the nation's scholars by Federal employment, project allocations, and the power of money is ever present - and is gravely to be regarded."

    If you're interested in the subject of snipers in general you might want to read this story [216.198.255.120] (and elsewhere) about a WWII Russian sniper named Vasily Zaitsev, and his duel with a German sniper sent to eliminate him. Various versions have the two adversaries stalking each other through the rubble-strewn streets of Stalingrad for days or weeks. The tale is often disputed and could have been Soviet propaganda, but it's a good story. I think it was also the basis for the movie "Enemy at the Gates."

    iRobot is the same company that brought you the popular Roomba robotic vacuum.

    Great. This is how it starts, people. First they make household robots. Then they make sniper-spotters for the military. Pretty soon you've got a Cylon rebellion on your hands. Then the Cylons go away for 50 years, return as human cyborgs, and begin having wild sex with your brilliant computer science guys.

    Hey, maybe those Roomba guys are just /. readers looking to get laid in their old age. Way to plan ahead, fellas!

    Since it must be mounted in the clear to ensure it is getting direct path sound, the sensors will be the sniper's first target. The added psychological impact of the troops seeing their sniper protection shot to hell is a sniper's dream. Thats what sniping is all about, sowing fear.
