Badass. That’s the best documentation I think I’ve seen yet on any of these auto-turret projects.

another gem from caleb kraft and his lack of spell check… the title of the video _clearly_ says ‘sentry’ whereas mr. kraft titled the article ‘centry’ … amazing

spellcheck title ;)

“more interesting voice options…” anyone else think of the Portal turrets?

NERF ENGINEERS

I felt ill when I saw a National Instruments USB-6008/9. Use a labjack instead of that overpriced crap, please!

Spy sappin’ my sentry!

sansan. do you really believe nerf guns contribute to violence?

Good presentation, but I had one small thought about the language used; It was said “basically” then there proceeded to be a paragraph of description describing how some thing worked and was sending signals. This happened twice and didn’t sound very basic to me.

Other than by regular bsing (above) I think you did a very awesome job with this. Physics book for the win!

badge recognition? yeehaw!
Thatt’l stop that durn red spy from getting so close to my sentry!

we couldn’t use a microcontroller because 1) this was supposed to be a matlab project, and 2) the setup we had (webcam and NI usb) worked fine and we had already spent enough money.

abumaia: you can easily change the sounds by substituting in different wavs in the sounds folder :)

They made an automated nerf sentry gun with tracking and recognition capabilities and the only thing they can be called on are grammatical errors?

-and what music they chose for the video?
-really?

Looks like the only thing you really need to do is a little proof reading on your presentation.
That’s like 5 minutes and doesn’t even involve the project itself.

I’d call that pure -= win =- fellas.

pure win.

Congrats on an awesome project.

Why is it that the lag on these “sentry” systems is so bad that even an out of shape person can dodge the aiming.

Put decent servos in there and either put in decent processing or close the loop tighter on the tracking. it should adjust aiming 60 times a second at least.

The phalanx auto guns reassess aiming 240 times a second

i was hoping for robocop sound effects personally. “you have 15 seconds to comply”

you could also use proportional navigation for better tracking. like a sidewinder

Now all we need to do is build a Nerf sapper and we’ll be all set!

You are in direct violation
of penal code 27 section C.

- You have five seconds to comply.

- Four, three, two, one.

I am now authorized
to use physical force.

I want one of those for my lab! That’ll teach the maintenance people to just walk in and start messing around near our million dollar equipment without calling ahead first.

Slow aiming is forgivable. MATLAB is *slow*, and there’s not a heck of a lot you can do to get away from that. If you implemented it in something less bloat-tastic, i’m sure you could make it much quicker.

Hey guys,

Great job guys! Did y’all use LabVIEW?

You can use the inputs on that 6009 instead of that stamp to control the limits.

What, No thermal tracking interface?

Very Cool! I never even thought this was possible!
I Love the badge part!

Very useful if you’ve got an Arch-Nemesis coming to your house!
