that contracts when given an electrical current, sorta like muscle?

and who is a distributor of it that I can contact to get a sample of?

get some from rudy salas the electronics shop guy, his number is in the ncsu directory

Shape Memory Alloy is similar to that. Not sure if it's exactly what you mean. (Or if SMA is way too general...)

^^i'm not a student anymore

^i'll see if that's what i was thinking

is this some batman begins shit

12/29/2005 8:59:17 PM

i'd like some of that too if it exists

but nah, i'm talking like muscle wire, but not metallic

Like the shit they used for the little stick robots in E115 back in the day?

piezoelectric ceramic elements ?

I think the material you're looking for is nitinol.

hmm, i thought there was some nonmetallic version of that

Dielectric elastomers but on a larger scale

oh well, i guess i'll give that muscle wire stuff a shot

Does it matter that it's metallic?

There's a group of materials called electroactive polymers but I think it's like some NASA type shit. I can't find a place to buy any. But I haven't looked that hard.

i want to try and replicate and real muscle with them so i'll probably have groups of them overlapping

i need something nonconductive that'll contract with them so as not to interfere with the other wires i guess

[Edited on December 30, 2005 at 2:00 PM. Reason : ^ohh i think that is what i was looking for]

1) Create a strong AI computer network and call it Skynet.
2) Superbadass robots from the future will come back to kick you in the nuts.
3) Fuck up superbadass robots.
4) Cut them up and scavenge whatever it is they're using for motion.
5)
6) Profit.

that's a lot of work
