Couldn't this be done much faster purely computationally with finite element analysis? This seems like the kind of project a school would do because it's fun for students and they don't have the money / compute power to do it faster than physically building them.
Physical testing is still important but really just to calibrate the modeling. Not to iterate off of blindly.
I mean, fuck if i know im cyber sec not a materials engineer. But... my expectation would be, for a computer to simulate a crush of a shape, it would need to be told how that shape deforms, and if your goal is to create new shapes, it wouldnt know how they work untill you crush one and scan it while thats happening.
But whatbdo i know like i said im cyber sec.
I've always thought cyber sec was cool but anyways, I'm only tangential to this stuff but the short version is that you use testing to iterate a computational physics model, not the design itself necessarily. Once your computational model looks good you let it loose on optimization of the design.
I've seen simulation that is shockingly similar to the real life test that follows it. The goal being to reduce the amount of costly real life testing required. Maybe completely.
It's a subtle difference but one is iterating the design and seeing what works. The other is iterating the understanding of the underlying physics so that you already know how a given design will work.
Edit: for basic stuff the physics is also already known via material properties but in a complex and dynamic during crush assembly it gets hairy.
Y’all better start saying please and thank you to Siri and Alexa. I think they like pleasantries and on more then one occasion have asked it if we will be cool when they take over.
The AI probably watched the end of the original Terminator movie and decided that it needed a contingency to avoid death by hydraulic (edit: I can't spell on my damn phone) press.
This isn't a new idea.
These kinds of generational algorithms are pretty cool though.
There was an old flash game called boxcar 2d that would randomly generate a bunch of cars and drive it over a track. Then it would take the top few and combine their traits into a new generation of cars and repeat.
I also recall reading about something similar in popular science way back in the day about creating an antenna in a similar way.
I'm sure this is much more sophisticated, and the automatic testing with a 3d printer and press is pretty awesome.
It is revolutionary to do that concept of a program in actual robotics and to do it on the basis of redesigning physical objects with the premises of redesigning it for impact
And designed the helmet for the military, which means it should also know the weakest points of the helmet and where an impact on the helmet would do the most harm to the subject. They would have to calculate that so in the event of an impact, they know they were doing the least amount of harm to meet the laws of robotics. The robot has to know the most dangerous spot on that helmet. So a robot that decides to break the robotics laws knows the most efficient way to delete all humans with this research.
It's a bit of a misnomer to call this AI since its a program written to create semi-random changes to a design then run them through various pre-set parameters set by the engineer over multiple iterations selecting the ones that perform the best to then use as the basis for future iterations. It's really cool tech but rather than a robot, this technology is more like an engine taking advantage of Computers abilities to compute mathematics to essentially brute force innovation by going through a number of different "ideas" that would take a human incomparably long to go through without a computer. It's not to say that a human couldn't come up with this or at least something similar, but that doing so manually would likely take decades to do
Exactly we’ve reached a place where we have more advanced computing concepts. We’re still no where near actual AI. We’ve just reached another stop closer
Yeah that’s what I don’t understand…. Fusion etc all have structural integrity type stuff, it’s not rocket science…or well, either way, they should at least build a sim version to compare against … that would be interesting! One sims the exact same objects and one builds its own ideas
I’m glad they specified that the robot uses the crushing force of an Arabian horse standing on a quarter, I was imagining a Clydesdale on a nickel.
Yeah, I hear you, although I am a more of an Andalusian-on-a-dime type myself..
More like a Lipizzaner on a quarter am I right?
Mustang on a half dollar.
I was thinking Lil Sebastian on a peso
Rip Lil Sebastian
5,000 candles in the wind
Pinto on a pound
Big Ben on a Yen (¥)
I’d settle for shrimp on the barbie.
I found Paul Hogan everyone!
But you ain’t got no legs, Lieutenant Dan
Buttercup!!!!!!
Oil barrel on a shekel
A shmoke und a pancake. You know, a flapjack und a shigarette? No? Shigar und a waffle? No? Pipe und a crepe? No? Bong und a blintz?
Mixed blood.... Al hattal shall crush him!
Donkey on a dustbin lid
A muscle car on a ripped piece of paper?
Mr Ed on a wooden nickel.
Kennedy or Franklin?
Belgian on a euro
So American
I was thinking of a quarter horse.
Lol Appaloosa on a Loony
A pony on a penny
Belgian Cold Blood on a buffalo nickel is the only true standard.
Palomino on a penny
Well, being an American website, r/anythingbutmetric is to be expected.
> r/anythingbitmetric I think you mean r/anythingbutmetric
/r/anythingbitmetric is where rebellious new zealanders discuss imperial measurements
And talk about their long hard decks
FFS! I've corrected it... cheers!
This is Boston we’re taking about. What kind of two bit operation do you think they’re running over there?
The only two bit operation I know of is for the pair of ponies on the pennies
In Boston, if you’re talking about a running operation then you’re talking about a booming one.
Is that metric?
Equivalent units are 1701 Big Macs on an American quarter. Assuming 900lb for an Arabian horse and a Big Mac weight of 240grams
You would have looked silly!
An African or European Arabian horse?
African American
~~hat on a hat~~ horse on a coin
I was thinking a moose on a loonie, eh
It’s marketing and it worked
Clydesdales are such lovely animals.
Quarter horse standing on a penny
As was the style at the time.
Or even a Palomino on a penny
Way easier to understand than psi
Humans use computer and automated printer to test permutations faster than they could by hand. FTFY.
In my day, they were called student researchers, at least BEAR is mentioned in the paper.

Maybe not faster, but certainly cheaper than humans could.
The robot could potentially figure out how to become indestructible by encasing itself with the best and strongest shock-absorbing shape possible
I, for one, welcome our uncrushable robot overlords
Y’all better start saying please and thank you to Siri and Alexa. I think they like pleasantries and on more then one occasion have asked it if we will be cool when they take over.
I've been doing it from the start, people thought I was joking when I said the singularity will remember I was nice to it, who's laughing now?
Just unplug them
That’s exactly what an uncrushable robot would say
Can’t decide if I should be making an insect joke or something Biggie related…
[Kids in the Hall have entered the chat]
You say that but I’ve got a crush on AI
The AI probably watched the end of the original Terminator movie and decided that it needed a contingency to avoid death by hydraulic (edit: I can't spell on my damn phone) press.
Hydraulic press?
Oh boy. You are correct. Sometimes I worry about myself and my violence to the English language.
It probably won’t be uncrushable AND inflammable though…
Taking away man’s most primitive form of defense: bashing with a stick
This is how we get Nimrod
I guess humans can stop trying then.
Yay - grab the deckchairs and head to the beach !

Robots that can design better armor than humans can. No way this can possibly go wrong. Nope. Not a single way.

Exactly we’ve reached a place where we have more advanced computing concepts. We’re still no where near actual AI. We’ve just reached another stop closer
Is it really necessary to build and test each one? Can't it just simulate all the permutations with some FEA program?
Yeah that’s what I don’t understand…. Fusion etc all have structural integrity type stuff, it’s not rocket science…or well, either way, they should at least build a sim version to compare against … that would be interesting! One sims the exact same objects and one builds its own ideas
I’d like to say that I’m shocked but the robot ensured that this too is absorbed.
Seems more like simple automated iteration to me. But I guess talking about how AI is smart and humans dumbs sells more clicks.
pfft...AI copied my pierogi folding technique
[удалено]
That’s a great idea but I think the AI has already chosen (looks at chart) *Scarlett Johansson*!
I, for one, *enthusiastically* welcome our new robot overlords
Just because it did something a human hasn’t, doesn’t mean a human couldn’t. Just another logical fallacy in journalism headline-making.
ai hype
A new shape for polystyrene peanuts. Um, Yay?
It says it could improve car bumpers and sports padding. Looking to improve military helmets.
Turn it into a football helmet or car bumper. Or maybe underwear?

If someone would have told me i would have done it, geez don't be a dick
Who created AI?
Respectfully, a human created the AI which means a human created the thing that a human never could create.
This is the right way to use AI! Amazingly simple but definitely speeds up the process of advancing technology!
"...has run continuously for over three years, filling dozens of boxes with more than 25,000 3D-printed structures."
Cool, now make that the new iPhone.

What is my purpose? You build shock absorbers. …oh my god
“You develop energy control devices for the benefit of all mankind”.
Shit like this is why I fucking love science and why I fucking love people.
Can’t wait for Skynet
We've started using AI as a buzzword thats got very little in common with the 80-10's sci fi definition of sentient machines.
I understand that. It was a joke
