Inchworm robot with muscle-wire

[NewAgeDirector]

Great video keep up the good work.

[Michaud12]

What voltage did you use? I noticed i need about 8 volts but i thought that seemed high

[DjRefunction]

Why?



[tynmorrow]

Inchworm robot created. US Military: (CONVERT CONVERT!) Now an Inchworm with rocket launchers and machine guns :)

[agent2539]

butwill it blend??

[CineBoxStudio]

its simple! it would prabably be pretty easy to do without the "tail", yust a blinking-type circut would do

[AZURA888]

if you push the wire more than 5% the life time will fall down a lot from 1000,000 herz to just 100,000 cicles of contractions.

Is better to coil the wire like a spring and put more material, of course like it is experimental is not necessary it resist so much.

[hotdad34]

stop sweeping...start inchworming!

[depicco]

hi, it seems the only actuator is the 'muscle wire', so you can not control the angle of the bristles, how do you know when they slip and when they stand still

[acidum984]

@depicco

If I saw it correctly - they are "angled" in one way, so this robot version can go only one-way. In order to change direction those would have to shift angle... If You understand my bad english :)

Anyway, I would like to see authors comment.

[Sasha101212]

YOUR OWN FLOOR SCUBBER! Wouldn't Mom be so proud?

[zederish]

at first 3 seconds I thought it's vacuum cleaner

[Chihang256]

wtf?

[activechaos128]

very cool

[Elijahsmokes420]

its like the HandBrake on your Bike, Duhhh!!!!

[necromx]

@Elijahsmokes420 Really the brake cables on your bike expand and contract in size???? I don't think so a hand brake on a bike just pulls one long piece of wire. This wire expands and contracts with heat changing the overall length of the wire enough to move the legs very different...

[Elijahsmokes420]

@necromx STFU

[necromx]

@Elijahsmokes420 Ahhh the typical response from people who don't know what they are talking about....No one tried to insult you genius...

[kittyfool101]

obly natreal inch worms are adorable D:

[BlazeDeval]

o.o

well why have that just get a real worm its cheaper

and there squish-able

[MarshFacev2]

Interesting, but what makes the feet slip and grip when walking? Is this controlled in any way?

[LiLPuNkEe003]

approximately how much current is the muscle wire taking? it looks like the wire is about 6 inches long ?

[COD5252]

LOOL its a snail

[mtb416]

Yes, that spring can be easily eliminated. I think they're trying to show what a muscle wire is at simply as possible.

[weaponeer]

thats getting close enough to act as a finger...

[taichimonkey]

I wonder why they don't use two muscle wires alternately.

[losghost]

@taichimonkey simpler design to just use one.

[otsegolectrik]

money is y,

[kichaaan007]

hmmmm.., tis looks good and goi to bring a revolutionary change i robotics....!

i m puzzled with the circuit connection ,,,, if u wish ,,,,,, pls explain abt the circuit connectns...!pls

[gaussman08]

LOL you can put a 555 timer circuit in there to produce the pulses and to make more compact :B

[basurero123]

It's really cool

[hdgasm]

I would like to see this done with electroactive polymers.

[bendhoward]

Is a significant portion of the power required lost as heat?

[mmmvideogames21]

what the hell is the point lol

[geolej]

its interesting

[masterpiraka]

To test the application of this memory wire, duh. I need to know. Are you American? I'm American too, I just want to know if i need to kill myself or not.

[mmmvideogames21]

Yeah I understand what they are doing, I'm just addressing the fact that an inchworm-like robot is useless. Yes I'm American, so go ahead and kill yourself. Thanks :-D

[masterpiraka]

It'sa proof of concept build. They just want to see if the metal can work and actually be applied to something.

[austinkx09]

lol

[ush92]

protoss reaver*

[ush92]

river

[kannedfaru]

With and army of these I shall rule the world!!!

[slopedarmor]

....

only if you have patience ;)

Pinky and the brain brain brain brain........

lol funny...

i dono why ppl rated this comment negative

[Milkmadness]

lsd lsd lsd lsd lsd lsd... what's new...

[Cr3ativity]

I wonder whether perpetual motion can be achieved with nitinol wire.

[Absurdity360]

It can't.

[adisharr]

Yes, simply wrap it around your neck a few times and then attach a 24VDC source.

[Cr3ativity]

hardy har har, you're soooo funny.

[DeltaWound]

You left out a k. Much better with 24kVDC. :)

[PacoBell]

Doesn't really matter. It isn't the voltage that kills you, it's the current.

[DeltaWound]

True, but the resistance of your body means it'll take a fair bit of voltage to do it. To kill yourself on 24VDC would probably require a pair of probes be stabbed into your chest.

Not a half bad idea, in this case.

[jonOHtan]

He's not talking about being shocked by the wire, when Nitinol has a current flowing through it- it contracts. So the method of death adisharr describes is strangulation- not shock.

[DeltaWound]

Well, yeah, but I'm adding a li'l fireworks to it. :)

(O ya, it's the ohmic heating that actually makes the wire try to revert to its original shape; it doesn't simply contract.)

Also just payed attention to that guys username. "PacoBell", LOL.

[tankedline]

BAHAHA

[mitchellintrieri]

what you need to do now is attach in series a batter, and a blinking christmas tree light to the terminals you created to make it untethered the battery will supply power, and the christmastree light is the cheapest and smallest interval switch

[gcjeong]

that is a good job~~

[spinaltron]

most excellent

[JoshSmithTV]

Omg!

Thats awesome didnt expect that.

Your next goal to the "WormBot".

Is to make it wireless!

Good Luck.

[Anden1990]

That one is the worm :)

[rooknoc]

atificial muscle implants for humans in the future probabely... thats exciting.

[bflk159]

very cool...I just purchase .008 inch flexinol (nitinol muscle wire) and the max compression of the material is 5% of the original length, while in your video the wire compresses way more than 5%.... I am thinking of changing materials after seeing your video and was wondering about the price, circuits set up and power source used to run the robot. thank you so much

[peterkatuch]

5% is enough. I use flexinol 100 in this robot. All flexinols have same contraction. Flexinol is connected to the end of front leg, then is drawn around the middle pin (bolt) and the other side of flexinol is connected to the rear leg. Flexinol is long enough to make this motion. Between the legs you can see the spring for elongation of flexinol after deactivation.

There was a simple circuit with PIC12F675 for driving, but you can use NE555 for switching on/off or just buttons for manual control

[Michaud12]

@peterkatuch

do you have a wire from the sma in the front foot coming back around to the back to complete the circuit?

[Michaud12]

@peterkatuch

100 what? inches? im not sure what you mean by 100

[mousetrap128]

@bflk159 can you get them a lot thinner? I'm thinking if you made a micro pulley type system using "muscle string" you can easily increase the total compression.

[shantiponks]

neat, its a start to something huge i bet

[QCpowarr]

its like a worm

of plastic ... lol

[JeromeDemers]

NICE! I like it!

[ti83master]

Very nice mate, very nice indeed :D

Tony

[OghamTheBold]

4 more and you got a crawling hand

[babot6]

this is amazing send me a link of a site with that kit

[peterkatuch]

You can't buy this robot. It's my own design and I made it from pieces of PMMA. The actuator is from Jameco.

[Michaud12]

@peterkatuch

link on jameco?
