Autonomous paintball sentry gun

[Alan] pointed out this great commercial paintball sentry gun. The gun has a low power motherboard running Ubuntu connected to a firewire camera. Two high torque motors control the pan and tilt of a Tippman 98 custom. The control box allows for easy setup. You can change the sensitivity, color tracking, and firing modes. It also has a remote kill switch. All around a nice looking machine, but at $3K we doubt many of you will be buying one. Beta test video embedded after the break.

    i personally like this one better
    but it doesnt seem to have color recognition, only movement. So i guess the commercial one might be better for team based games

    $3500 if you want the WinXP version :P

    I was going to say ‘not another airsoft/paintball sentry gun!’ but the linux makes me say otherwise.

  3. Jack Ward says:

    this could be fun for home security, but damn i want one

    Whoa! I need one of those in my garden.

    “… designed by me, built by me, and you best hope, not pointed at you.”

  7. eww, commercial.

    Just shoot a portal at a wall and one below the sentry and your golden…


  9. Andrew B. says:

    ahh at least they could of used something much better than a tippman 98 custom.

  10. sam says:

    I actually donated money the other day to a similar project you can find at So cool.

    Good point #3:
    Drop a weighted companion cube on this thing and it’s done.

    I’m not donating anything to a project that’s written
    “I’m not giving out the source code. it constantly changes anyway. “

  14. Mantari says:

    How do you keep the spies from sappin’ your sentries? Does this come with a gigantic wrench?

  15. Glen says:

    those things are easy to take out. all you need to do is hack together a gravity gun ;-)

  16. James says:

    And, how long will it take before someone has an ak047 hooked up to this thing?

  17. argz says:

    It would be cool if you could monitor it’s status over ethernet. Maybe stream the video and allow people to remote control it if possible? Add SMS notification of motion detection, wifi, and pepperballs and I’ll buy 2 :)

  18. Alex says:

    When Ultra-Sapper device is affixed to the top section of the sentry device, remove red and green
    wire and tune dial (bludgeon device with reckless
    abandon using wrench included in package. Follow
    up with sporadic shotgun fire in the immediate
    vicinitiy of sentry device. Shotgun also included in
    package.) to frequency KZQ-10z.
