Re:Awesome! (1)

Good hours. Great pay. Check your soul at the door, unless you're a True Believer (TM). How do you know if you're a TB? Here's a simple test:

We have to give up certain rights, like the 4th ammendment in order to preserve our rights.

If you agree, you're a TB. If you think it's bullshit but shove it into the back of your mind and remind yourself that somebody has to feed your kids, you're not a TB. You're just a douche. You'll probably get the job and do OK though. If you wonder what kind of dystopian nightmare your country has become, you plainly think too much beyond the "it's cool" factor and you will most likely not fit in. You might blow the whistle when you see something bad. You might decide it's better to live under a bridge. You're better off not getting into this field in the first place. Try social work, or if you're not the social worker type and you're still fundamentally conservative (and yet have a conscience) then consider the ministry, driving a truck, or some other occupation that doesn't involve such moral compromises.

Or wire up a couple of Airsoft machine guns with large magazines. I think they are battery-powered and the triggers are just switches so it should be easy enough to replace the manual trigger with an arduino-controlled one.

Re:Mini-gun (1)

h4rr4r (612664) | more than 2 years ago | (#40006497)

No need for magazines, there are plenty of airsoft guns that fire from hoppers. That way the inside of the turret could be a hopper like GP suggested.

Typically in the past Valve has ended up buying the devices from people and putting them in their lobby, They have full size TF2 Sentrys and a Portal Sentry but they do not actually fire things. All you have to do is search for them and you will get the pictures.

Besides, who's making a living selling this kind of thing? It's not as if Valve is competing with these people and their products, it's an obvious synergy.

None. This isn't the first Slashdot story about a guy combining motion control and a weapon. I wish I could find the story, but at least 5 years ago, maybe more, some guy wired together a turret holding an automatic bb gun and motion sensing and control. And it was a lot smother and faster responding than this. It was kind of funny because he shot the shit out of his brother or friend or whoever it was halfway out in the back yard. It was a couple of bursts and then they stopped.

http://www.youtube.com/watch?v=RxBa5bQfTGc&feature=player_embedded#t=62s

http://www.paintballsentry.com/

Its tracking and rate of fire is pretty terrifying, in fact. I don't see why it couldn't be sleeved to look like a Portal turret too and be way more impressive.

Re:And? (0)

Anonymous Coward | more than 2 years ago | (#40006607)

Between this and the original article, I think (I'm not a weapons person in the slightest btw) the objective was met in that it a) tracked and hit the target, and b) did so with a cheap usb camera or something as simple as a kinect(which would probably have better depth perception.) The portal sounds and shape are just frosting to make it realistic from the game.

IMO, the one thing I'm kinda 'meh' about is that the actual work is being done by the laptop in both situations. I'd be far more impressed if they managed to put the entire thing in the turret, and then communicate with it wirelessly.

Any idiot could mock this up, and hes using matlab instead of embedding everything. The turrets move when the 'real' portal turrets swivel at the base. In short this is a shitty turret tracking system with some bullshit plastic cutouts that look like ass to give the impression its a portal 2 turret. I was expecting something like the turret they have in Valve's office. What I got was a college pet project that looks like ass and functions worse.

I can't but agree. For crying out loud, one can build a much smoother tracking system using image processing on a Parallax Propeller CPU, and that thing has 2kbytes of RAM per core (cog). Using matlab to run something so simple that has an update rate in low single Hz is a letdown. I'd have expected it at least to run at webcam's framerate. It is lame and unworthy of slashdot's frontpage.

Re:Needs a lot of work. (2)

msobkow (48369) | more than 2 years ago | (#40008005)

I agree. Way back in 1988, one of my university cohorts developed image analysis and recognition software that would identify a target and paint a crosshair mid-torso. Of course in the age of the VAX 780, it was far from real-time processing. But given that even "slow" computers are over 1000 times as fast nowadays, there is absolutely no excuse for the apparent processing delays in this project. (It used to take an hour to do the analysis and paint the crosshair on a graphics terminal, so with 1000 times the processing power it should be able to do it at least 16 times a second on even a P4.)

Maybe they made some bad choices for their software. My friend's work had been raw C code, not a higher level package or interpreter like MatLab.

Re:Needs a lot of work. (2)

msobkow (48369) | more than 2 years ago | (#40008061)

The '88 software didn't require any cheating like using a bright pink shirt so it would stand out from the background, either. It would track anything human-shaped that crossed it's path, and was "smart" enough to reject other 4-limbed creatures like cats or dogs.

Rather than centering on "the pink blob", it used some interesting algorithms to build up a stick figure of the object, identify the torso stick, and aim for the middle of the torso stick.

They had a lot of fun on that project. Pretty much everything except the software used to drive the graphics terminal and do the image capture had to be custom coded.

Looks like it was a real fun hack, kudos to the kid, better than anything I'm trained to pull together, and the aim wasn't too shabby!

But...

It's really generous to call it a "real-life portal turret."

The tracking was jerky, it waited until the target was stopped, I think it was tracking the red shirt, not the person, and the vocalizations were coming from the laptop controlling it, not the device itself. (At least, that's my guess given how quiet the voice got when the camera was placed behind the turret for the "live fire" demonstration.)

I think it's a great student project, but what I'd really love to hear is that he's going to continue to play with it, seeing how far he can push it towards self-contained as possible. That'd be fantastic!
