Muscle wire actuator

[andrewmcAAndrews]

Thank you very much. Good demonstration. I want to use muscle wire for my robot projects because servos are way too loud, and become annoying very quickly. Thanks.

[SettimaLegione]

compared to motor servo, this is perfectly silent?

[AZURA888]

sumerge the wire in water so it will get cooled quickly, water disipates the heat 25 times quickly than air.

This wires has future as muscles even if only can support 5% of shortening.

[chwuwd]

i would personally use servo for this kind of application

[warp13]

about how much current are you using in the wire and what size wire?

[MicrotekMybisi]

That's some big ass graph paper... Or a tiny, tiny person...

[KottonmouthSoldiers]

@MicrotekMybisi looks like standard centimeter...

[tomview1]

@Soulrider2012 - I agree with you 90+% of people commenting are truly dumbfucks.

I belive you are not - anyhow to know more about this muscle wire stuff - go direct to the manufacturer - get a sample pack.... .toki.co.jp/biometal/english/c­ontents.php

[nnnnnnnnnnnnnnnnn984]

hi may i know where did u buy this wire and what is its name n specs?

thanks

[Kirby00216]

@nnnnnnnnnnnnnnnnn984 You can actually buy an assortment of this at jameco .com for $36. just search "muscle wire"

[truestyleoutlaw]

good now make a hand

[Soulrider2012]

Probably 90% of the people posting negative comments don't even understand the mechanics behind Nitinol wire (memory wire) or have a clue how this works. It's not just a mechanical servo going back and forth. It's actually very cool stuff and it's great to see people finding new uses for it. Can this same action be done a different way, sure and has been but this is something more high tech and interesting.

[MurthyER]

This is what happens inside RC cars for steering. Whats point in showing ?

[PAULCCFOX]

Left , right , left , right , left , right , pointless

[activechaos128]

cool

[npatel984]

stupid jer.k fker video westing time.

[chil0man]

i can synthezize a better one dude..honestly.. this is basic electornic

[weaponeer]

a little smaller and it would be great for artificial fingers.

[xxjacobxx3]

すごい although... i would like to see a demonstration of how strong these wires are, compared to how much electricity is used.

[salzahrah]

is there anywhere u can buy this type of machine?

[shakemytree1]

it reduces having a streight face orgasm..

[horizonflyer9]

it looks like a mini servo

[UntakenNick]

Where do you get those "muscle wires"..?

[Jimbogf]

unitednuclear . com sells them, they are called "nitinol muscle wires"

[kattejuice]

eletronic's shops

google it! :)

[Clamburgers]

So is there a restoring spring? If you apply heat the wire contracts, but after it contracts and the heat is removed, it will elongate, but wires can only pull, never push. Can someone clarify?

[DeltaWound]

Prolly a second wire in opposition to the first.

[Soulrider2012]

@Clamburgers The wire has two states cold and hot. In the cold state it is soft and you can move it. When heat is applied through hot air, water, or electric current the wire returns to it's memory state and tightens up so yes, it can go both ways on it's own. All it needs to do is cool down and the wire will pull the other way. Heat back up and it pulls the other way again. Back and forth. I didn't realize it happened this quick though. Cool stuff.

[COROVICD]

Great work and great idea.

But you shouldn't be showing this on YouTube if you haven't applied for patent. You will loose a serious amounts of money in royalties.

Good luck.

[necromx]

@COROVICD This isn't patentable...

[dertuman]

thats crap. better just buy a futaba S9650, and a receiver and Tx, and you get 3 kilograms of torque, and an impressive speed!

[hjnl1968]

Yeah. And you can even have fun driving to the store.

It is way more fun to buy things that to use your brain, apply your skills and imagination to create something... right?

[wans93]

right!!

[fairyheli2]

how does it work?

[6364gg2]

M.wire heats up, it contracts, and its connected to a round thing. So whan it pulls, it makes a rotational force.

[fairyheli2]

how does it push?

[6364gg2]

It reverses polerity

[untonn]

Very interesting.

So, if you put, say, 20 of these muscel wires in parallel and attach a 10:1 gear, you could get a better torque and speed, right? How much current would it pull?

[mattt170]

were would i get that at?

[Chronoholix]
