Sentry gun controller

Thanks to Bob's open-source Sentry Gun controller, now anyone can build a gun that "autonomously tracks, aims, and shoots at targets using a webcam."

(Via Dangerous Prototypes)


  1. Pretty soon anyone will be able to build a fully autonomous combat ready robot in their garage. Why does this not make me feel better?

      1.  One who believes that such a sentry gun can work flawlessly is neither intelligent nor knowledgeable.

  2. Cool. I know a few people who made sentry paintball guns. Worked really well too. Right out of Aliens. 

    1. I don’t think of “Worked really well” and “Right out of Aliens” as phrases that get along well…

      B gun’s at 20.

    1.  Exactly.  I want one of these mounted on a Sand Flea.

      Unsuspecting burgulars standing around on a roof…  then….

      SURPRISE!!!  AR15 SAND FLEA!!!  Brap brbrbrbrbrbrap rap rap!

      Solves that problem.

      1. I will need to update the  software to properly recognize and respond to your AR15 Sand Flea.

        1. My AR15 Sand Flea will shoot your Robo AR15’s bullets, and I will have an extra bullet to finish the job!  then BOINGGGG, back to ground level.

          1. My horde of spherical self-propelled neutron-pulse generators will take out your quadrotor electronics, as the sand fleas leap to a safe distance.

  3. So does this mean an actual Gun gun or a Nerf gun, or a Super Soaker or a laser tag gun or a paintball gun?  Because if people are automating real firearms I need to buy a small valley somewhere – nowhere if possible – and dig a hole in it to live in.

    1.  if it’ll work with a paintball gun, it’ll work with any other gun you care to hook to it…

      1. Not necessarily. The recoil from many firearms would rip a mount for a paintball gun to shreds.

    2.  And what’s really great is – once you get your small valley somewhere, you can protect it with automated sentry guns! Automated sentry guns, the problem that solves itself!

  4. That high-pitched humming you hear is Isaac Asimov spinning in his grave.

    (People pointing out that Asimov was cremated will be sent to the sentry bot testing arena.)

  5. Can you give it a voice that sounds adorable, saying “Who’s there?” and “I see you.” ?

    1. Personally, I just want to make it immune to Autohack darts.

      Still, “No hard feelings” is just the polite thing to say when toppling over.

  6. It might be just as effective with a laser sight and blank ammo.  That would be a trouser-soiling experience.

  7. A chair may be more stable and available than a tripod, and would make this a Bioshock turret.

  8. The only practical application for this is the coming zombie apocalypse.   Therefore, I applaud the open-sourceiness of it.  It takes a brave man to declare that zombies are a threat to all.

  9. Oh good! Nothing bad could possibly come of this. Perhaps they could sell it into gated communities in Florida.

  10. If you can destroy the system with a $5 laser pointer and a bucket of water it’s probably not a good security alternative.

  11. how about an automated sentry robot that greets the intruder with a nice cup of tea? then chats with your uninvited guest about lifestyle choices and how a positive social contribution will add to a sense of personal well being…

  12. I wonder how hard it would be to adapt the software to control a USB foam rocket launcher.  That would be the ultimate in desktop defense.
