Self-Sculpting "Sand" Can Allow Spontaneous Formation of Tools

samzenpus posted about 2 years ago | from the shape-of-a-sand-tool dept.

Technology 124

parallel_prankster writes "Researchers at MIT are developing tiny robots that can assemble themselves into products and then disassemble when no longer needed. 'A heap of smart sand would be analogous to the rough block of stone that a sculptor begins with. The individual grains would pass messages back and forth and selectively attach to each other to form a three-dimensional object; the grains not necessary to build that object would simply fall away. When the object had served its purpose, it would be returned to the heap. Its constituent grains would detach from each other, becoming free to participate in the formation of a new shape.' To attach to each other, to communicate and to share power, the cubes use 'electropermanent magnets,' materials whose magnetism can be switched on and off with jolts of electricity."

Agree. I don't have a smart phone and there is no wifi for me to use. So I have to print out the slashdot comments and take them to the shitter to read. I use Firefox and print them at 50% scale. The first ten pages are enough to cover a 15 to 20 minute shit.

It was in one of these print outs that I discovered a post deletion functionality built into the slashcode. The delete post links were quite clear when no CSS or javascript was applied. But I digress.

Nothing pisses me off more than the first 6 pages of my print out being the same redundant and not funny joke or reference. Slashdot use to be a place for intelligent discussion where I learned something new everyday. Now it's a stagnant turd no better than what I flush down the toilet.

dissy (172727) | about 2 years ago | (#39553579)

Not to mention the research on the theory started very long ago.

My personal favorite book on the subject is Engines of Creation by Eric Drexler.
(The original [e-drexler.com] from 1986 available online.)

The late Robert Bradbury also wrote quite a few related papers with more technical details, such as "Nano assembly of an aircraft carrier", "Planetary Dissembly", and "Molecular Construction Limits"

Exactly how small is possible, and numerous methods to go about it once we are able to construct items that small, and even the planning ahead to prevent the obvious (and not so obvious) disasters related to such technology have already been addressed and answered by many scientists over the last century.

It's not the universities and researchers we need to keep an eye on, they've had their day here. The next major breakthrough will come from the manufacturing sector, and they have quite a ways to go to meet let alone catch up to current theory.

I'll be excited once a similar announcement comes from Intel or IBM or the like, once they have a working prototype.

flaming error (1041742) | about 2 years ago | (#39553349)

When we are arrested we are by definition stripped of certain liberties, and privacy is the first to go. Unpleasant, but that's jail.

I think jail is the worst possible way to treat most anti-social behaviors, and I find our wholesale imprisonment of the population to be counterproductive beyond idiocy.

But regardless of whether particular suspects/convicts should be imprisoned, jailers always need to keep out contraband.

Re:Murder Weapon (1)

NatasRevol (731260) | about 2 years ago | (#39554187)

Not sure what your point it. The police can take you to jail for any arrest. Thus, they can strip search you for any arrest. Even trumped up ones. Even false ones, like the one argued before the Supreme Court - unpaid fine that actually was paid.

electropermanent magnets turn off with current, not on. The electromagnet neutralizes the permanent magnet while the circuit is active. This makes the connection via the permanent magnet energy efficient - no current is required to turn it on, only break the bond.

ThunderBird89 (1293256) | about 2 years ago | (#39550901)

Miniaturize them far enough, so they can float in the air and still communicate and grip, and you have what's termed a utility fog. Such a fog would be tremendously useful, provided proper authentication and encryption could restrict control to authorized persons: tools could be formed freely and to unheard-of precision, in real-time, responding to the needs of the user; weapons could be supplied with unlimited ammunition that disperses on impact, only to be reformed in the weapon; cars could do away with airbags and seat belts in favor of hardening the atmosphere for a second to affix the passengers in place in the event of a crash; or even enforcing the laws of morality like physical laws (I read this last one in a novel long ago, where the air would harden around the striking fist to block the punch). The possibilities are literally endless, if the technology can be implemented properly.

Re:Taken to the logical extreme... (-1)

We could use that utility fog to devise ingenious ways to torture American citizens that are being subversive. Or even if they aren't, we can still torture them with the utility fog and get a false confession out of them, which would justify us executing them.

Just think of the potential such a thing would have for the American government. :)

yes. and you could have a pencil like thingie, maybe longer, to point at the volume of fog that should do what you want. and you should make voice commands for the pencil thingie (let's call it a wand for short). or maybe the wand could spit out the utility fog once you say the right words, and it would come back after the job is done.

Or have them form into a thin shape that's larger than the lung can contain without rupturing. Or have them simply block all air passages. Death would follow shortly thereafter without ever needing to actually shoot at anyone.

Because eradicating humanity in favor of your synthetic life makes perfect sense from an economic ("humans are wasteful, they gobble up resources too fast", etc) and security ("humans are unpredictable, they may turn on us, so in order to ensure our survival, the chaotic variable must be removed") point of view. Unless you hardwire the thing to be friendly, it will eventually turn on humanity, and if your implant human-friendliness as a basic directive, it no longer possesses the free will required of a strong AI.

It doesn't need to be homicidal (agreed this is unlikely unless designed with that intent in mind). A sufficiently powerful AI only needs to be indifferent or the wrong sort of friendly. Try defining how a friendly and very powerful AI should behave without it leading to undesirable outcomes.

20–23 10-ft. cube
24+ +2-1/2 ft per 4 points of Wisdom
If your Wisdom check succeeds, you can reshape the volume of sand as you desire. Once control is established, the shape lasts as long as you remain within 100 feet of it.
Thus, those with suffi cient patience and strong enough will can construct small fortresses out of shapesand, even if they must do so a few cubic feet at a time.
Another character can wrest control of a shapesand item away from you by succeeding on an opposed Wisdom check, though the winner’s Wisdom score must be high enough to shape an item the size of the one contested. For example, if two characters are attempting to control a 5-foot cube of shapesand, the challenger must not only beat his opponent’s roll, but must also have a Wisdom score of at least 12.
If you are a sand shaper (new prestige class, see page 76) or a cleric with the Sand domain (see page 107) using shapesand in conjunction with your sand shaping abilities, you do not count shapesand items against the total number of items you can maintain at one time. In addition, if you are a sand shaper, you can give control of shapesand objects to other individuals, and those items persist even if the new owner takes them outside the normal 100-foot control area. The new owner need not make a Wisdom check to establish control of the item, so long as his Wisdom score meets the minimum requirement for the object’s volume.

Anyone read Trillions by Nicholas Fisk from back in 1971? Sounds like MIT is making science fact..

Cubes? (2)

Is cube the best shape to use as far as manufacturing and self-assembly goes?

They talk more or less about re-using blocs by dropping them into a box, but cubes never pack up neatly, no matter which size they are. Is there a geometric shape that stacks automatically in 3D?

Also, I don't get why they keep writing "10mm" instead of just "1cm".

I'll be back... (0)

I totally already saw this technology in Terminator 2.
