Artificial Muscles And How To Make Them
Вставка
- Опубліковано 9 лют 2025
- This might be a bit ropey in terms of production values but i made it on holiday - always had a fascination for artificial muscles - this type works on heat - so sunlight, hot water or maybe a resistive wire down the centre - loads of stuff to do with this
I see a lot of potential in these muscles for a semi passive exoskeleton. Really awesome idea and it’s really got my cogs turning
Cool. Now I know what to do with that huge spool of fishing line laying around the house. I love experimentation!
go for it mate
I watched the entire video intently😂🤣sincerely appreciated Robert😁
I am so happy to have found you. You are a gem. Thank you
Thank you! I did actually watch the boring stuff 😂🤣😂 because you are so brilliant you deserved my attention through the process. I love that you're YOU on vacation,challenged to make do with what is there and STILL Being absolutely brilliant. This is a 3yr.old video, but as a newer subscriber I appreciate it. You give me and others immeasurable gifts that help us with lives that we don't get a vacation from. So wonderful are your videos that they ARE beautiful mini vacations for my mind & spirit. New ideas& things to try that I can actually do with my limited resources is very exciting &brings great joy. It's so wonderful what you are doing it's important you know that it makes an incredible positive difference in people's lives. I'm fairly isolated from reasonably intelligent people.. you've been a great discovery to me that I am grateful for.Thank you for all you do. Please do these videos as long as you can because they are some of the best content on UA-cam!❤️👍
The holiday cottage doesn't have equipment FOR A REASON! Aside from that. :) Very cool info.
The curse of the working man. Vacation is never really a vacation.
very very true mate lol
@@ThinkingandTinkering And for you sir, you appear to be one of those rare few that find work to never really be "work", but more of an adventure.
@@Cylon39 absolutely mate - life is an adventure lol
@Merlin Young lol - for sure
I suppose it depends on if it's your job or hobby. In my case, when I need a break from working my business, I go explore renewable energy and quantum physics. Then back to work. Got no need for TV. It bores me. Vacation? What's that? It has more than 4 letters so I can't even spell V.A.C.A.T.I.O.N. lol 😆
For those entrepreneurs out there...remember that JOB is an acronym for Just Over Broke. I wish all of you a great day and hope you keep the grey-matter active.
with a spring, a pulley and a pointer, that's a great thermometer.
Very cool, I highly recommend you read this paper "Spore‐Based Water‐Resistant Water‐Responsive Actuators with High Power Density", it will blow your mind. It's an evaporation based system with very high response times and power densities that uses spores much like your coiled nylon wire.
you are right an absolutely fascinating paper - thanks for that
I respect your ingenuity.
lol Science IS your Holiday Rob! :) Thanks for the cool video!
Kudos, Rob.
When you get back to the lab and have a drill handy, try partially filling a water bottle suspended from the line and attach a lever arm to the bottle that will contact something to keep it from spinning. The paper I read when I did this gave the suggested weight to apply based on the tensile strength of the line, for optimal coil twist. These are loads of fun. Thanks for a playful holiday project.
i think we read the same paper mate - cheers lol
@@ThinkingandTinkering No doubt. I found that silver coated nylon thread did not work very well as a heating element, but it was easy to intertwine down the central axis after the line was twisted and heat-set. It remained flexible, unlike nichrome. I'm thinking your conductive rubber formulation would work well as a dip coating, knowing you've used it as a heating element in prior videos.
@@dgpreston5593 it probably would mate - i might give it a go when i get back
There is no holidays from being scientist 😉 great video 👍
lol - so true
Now you can coat it in your graphene. Run a current through it to make it heat up. Then you got an electric muscle with enough of them lol.
@@aaknuu you also can use the nylon fence wire for electri fied fences. The metal wire is already included 😉
Cool, love it ! But your vacation is gone! God bless Patti.
So cool rob! You can take the lab away from an inventor but you can't take the inventor away from inventing!
lol - absolutely mate
Thank you Robert.
Your on a Busman's vacation then? Fun fact the hairdryer not only generates heat ...but also negative ions.
Hi everyone! Robert, I was wondering if a guitar metallic string would do any better by any chance? I thing those are also twisted like an artificial muscle, what do you think?
Wonderful! Thanks for sharing!
hahaha awesome! little bit outta left feild, but deffinately interesting. both the concept and how thinking minds never reallly stop even when on holiday.
i know what you mean mate lol
Flags wave in the slightest wind. Could an artificial muscle capture that motion/low frequency vibration? Artificial muscle in rope used to run it up the flag pole?
You might make a sort of radial engine, using radial muscles taken to a point off centre to the axle. One side then heated.
Use this for the string inside a stirling engine?
Robert, isn't it possible to make graphene coated pipes with water pumps attached to them? Don't you think they would pump water for hydro power?
The artificial muscle is how long in the wind tube you made ? Thank you for your time and Ideas 💡
Use it as a switch or a pump for a solar air water heater or air heater or generator. When it gets hot it closes which then let's the line cool which then it opens.
Thanks for sharing Rob! You have a strong mind!
cheers mate
Could a guitar string be used as artificial muscle?
So good to see you doing what you enjoy doing, inspirational ideas. Thermal muscles, turning heat into motion; What a concept! It shrinks with heat, I thought it would expand. Put a tubular sponge over it and it will revolve from a pool of warm water (limited temperature) and evaporation, cool. Please come back, we all miss you! .... Make a graphene microphone that's better than your carbon one!
yes i thought it would too and i was surprised but apparently if you wind it in one direction only it shrinks and if you contra-wind it - that is irst wind in one direction then coil in the opposite direction it expands on heating - not tried that yet but will for sure
How about shape memory polymers? They may work for a generator as well. Maybe a modified Dr Johnson's Nitinol Heat engine using a shape memory polymer instead of nitinol. I imagine that it could have much better cycle life.
if you build a windless generator unit and install several muscle cell will it increase amp's; one unit with several muscles. also if you used weed eater string to make a larger muscle would this catch more vibration and increase amp's??
Can I use brush cutting nylon to make artificial muscles
What is the research paper link or title?
A rubber band also does it. Thank you.
Can a small strand of Nichrome wire be coiled with it?
When do you lay back and rest apart from sleeping. All work and no play--------------------------------------?
absolutely outstanding
cheers mate - one has to do something on holiday
Very cool, thank you
A bi metallic metal sheet moves with heat as the metals expand at a different rate causing plate to bend with heat or electricity
that was the longest 5 minute windup in my life
I saw someone make conductive nylon one time but I believe the process was very toxic so I never investigated more about it, but it would be fun to have access to some of it.
i think there are other methods you could try - coating it after - maybe dissolving it in acetic acvid and dispersing graphene - i don't know but a few ideas do come to mind
Hi, I get kevlar out of the sides of bicycle tires so I thought I would try with a bit. I tried raw kevlar, some coated with bees wax. both failed, but perhaps I am winding too tight. hmmm
keep at it mate - cheers
I did something similar to that with my power drill. It makes short business of it!
awesome mate
Is there any way to create ultra thin (1-3 Micron thickness) films of Mylar at home without industrial machinery and deposit a film of metalization on it? I am trying to see if it would be possible for me to create homemade metalized thin films so I can create a condenser microphone's sensor from scratch. The electrophoresis path led me to a dead end when I tried to metalize saran wrap since plastic doesn't conduct electricity.
Look up sputtering it deposits a film of metal on a surface
@@davidmayhall6567 Yes, I'm actually familiar with Physical Vapor Deposition techniques like sputtering but I was hoping for something that was less mechanical and at least doesn't require a bulky vacuum system. If there was a process similar to how old-school mirrors were made where silver particles deposited on a smooth glass surface that would be ideal.
@@shayhan6227 mercury vapor mirrors mercury salvaged from a thermostat mercury conducts electricity. But how about using activated carbon heat it up don't let it combust then grind it fine it can be glued to plastic a current collector wire can be glued then a carbon powder mixed with a binder flexible binder or stiff binder, vinyl or a white glue mixed with powder carbon the carbon can be deposited on a plastic surface with current collector wires laid in. If you want plastic aluminum try using a lamination machine and a plastic run through laminator and bond foil to plastic
You can use a piezo crystal speaker as a microphone, or use a earbud speaker as a microphone, old school carbon electret microphones was a can of hard carbon chunks with a thin metal plate as a current collector Soundwave vibrates the plate compressing the carbon decreasing the resistance through the carbon. A laser microphone uses a laser beam to bounce off of a glass window or wall and the reflection carry the vibrations and is picked up by a decor diode then amplified into sound. A homemade quartz microphone could be made with cut pieces of quartz glued with cold solder paste to a brass disc the vibrations compress the quartz varying the current flow through the quartz crystal
A thin magnet glued to a brass or plastic plate with a coil arranged around it will produce current from sound waves any speaker can be turned into a microphone. I seen a big bass woofer wired up as a microphone to spy on people it will pick up small sounds if placed next to the floor
high frequenci or high voltage [supcapa] electrolise nylon 3d printed torsed that do a little kind of peltier ?
Combine this with your linear switching reluctance generator.
Love it! Good job 👏
cheers mate
Paint the muscle with your conductive ink , then if you connect it to the electricity , it heats the muscle and it will works the same with the hair dryer :) when you disconnect it , it cools down and long again :D I think it will works well like this ;)
Now I have read the other comments , same Idea ;) give it a try
or you could mate!
Wow! If we just make this several times faster, it might be fast enough to make a robot slug!
lol
Interesting, but you never really explained why the coiled nylon changed its size or why the process is reversible. The biggest problem is the huge energy input required for such a small reward. To have any advantage it would be necessary to entwine the heating element with the nylon. Unfortunately the failure mechanism is all too obvious, with the heater melting the nylon.
no i didn't but if you want to know more just google it - also you are watching a garage holiday experiment - it should just be interesting - you comments on efficiency and failure are to be honest a little premature i feel
@@ThinkingandTinkering to some extent I accept your comments, however using a 1 to 3kw hair dryer to change the shape of the plastic suggests that it requires rather a lot of energy to work. The comment on the failure mechanism relates to entwining a heater wire in the plastic. Such local heating would I am sure result in melting before the heat had a chance to spread to the bulk.
I think what we need is a material that rapidly contracts on application of a voltage. This will require some very clever material science and some engineering at the molecular level, not something for a holiday project. We still have a lot to learn from nature. Much is made of recent developments in AI, but we still have a long way to go to mimic the processes and miniaturisation of a simple insect, such as a house fly. These thing fly, walk, fed and find mates and reproduce, they are also the devil to swat, actively evading attack. All this under the control of a few hundred neurones, can't help thinking we are missing a trick or two.
@@nigeljohnson9820 really i am not trying to be mean here - please read the research mate i think you'll find they cover your points - the main reason i did this was to excite interest and demonstrate how science can be done with minimum tools by anyone but one of the tools most of us have is the internet and the ability to do and read the research - so though i appreciat your comments i reccomend you have a read to investigate your points first - then maybe comment in the vien of - 'i was worried about failure and efficiency but i read this .....' that would be so much more helpful to other folks who do read the comments - than simply i don't think that will works because - which is basically what you posted
Hey Rob , happy holiday times ,curiosity is the mother of any invention indeed ! no holidays can take ya from it😁 though this subject already been investigated thoroughly your findings as a scientist always tremendously appreciated, Rob I was thinking loudly if i may say so! how about if soaking/coating the nylon or PVA fiber with your graphented jelly then insulating the coating with elastic non-conductive thin layer then applying a current to both ends of the muscle ON/OFF wi that make it contract and relax? cheers mate! enjoy your holiday👍
that's one of the good things about this - there are a ton of good research papers out there and even though a lot of work has been done i think there is a ton of stuff to find out about it - especially for those who want to look at something but don't have a lot of equipment handy
of course i agree to that mate ,the good thing is to make it simple as you mentioned earlier without that sophisticated machinery processing,and you've made it as simple as that ! thank you again for that awesome idea.cheers mate.
@@amazac2078 cheers mate - have a good one yourself
@@ThinkingandTinkeringit worths to try . yeah
Hehe, you do make me smile Rob! Can't keep a great mind down for long eh! Love the idea of your conductive ink to help activate the muscle motion....Cool!
yeah i like that too - i will give it a go when i get back to the lab i think
id like to see implementation of some form of internal heating element in order to drive the actuation
twisted around or alongside copper wiring for instance
build one then and do a video
There goes someone adding their imagination to your "muscle".
@@rickdees251 indeed lol
I really don’t see a “muscle”. I see a “string” that has been twisted. If it is to be a muscle it needs to be able to contract and release. I don’t see is going to happen with just a piece of nylon that has been twisted.
Vacations are more stressful then work. Maybe just a week or two of shorter work days would work. Probably not.
for sure lol
Wow! RMS with a twist!
lol - absolutely
Heat engine. First thing that came to mind.
same here mate - great minds eh lol
nylon electrolise that was aluminium or your grafit2 as anode
"Where there is a Will, there is a Way!" ... ;) and by the way... I had an idea of Solar SMA Motor by just making an alternative screen turning to warm the muscle on time and put it shadow the other time. The Main Idea is that it doesn't take much of power to turn a screen so the chance to have a COP overunity looks to me Great :) but it was with nitinol, might work with Nylon either :)
nice idea mate - cheers
You`re awesome man, really.
lol - cheers mate
Sir, I'd VERY much like to contact you regarding graphene plastic manufacture...
Awesome !
cheers mate
Find a wire hanger and make a crank to do that job. Twisting.
or whatever works for you - the important thing is to give it a go
Interesting
yeah i thought so - more food for thought than anything finished and definite - but interesting for sure
Wrap the coil in copper coil and add electricity
go for it
I watched something a while ago where the coil was heated within a sheath containing a copper coil or some such, thought that might be interesting to you. @@ThinkingandTinkering
@@hadfull9889 it is mate - but tbh i would be more interested if you had done it and done a video too
Hi Rob, I am tinkering in the lab with iron filings and soft polymers in a balloon once and if I get it right I will. Thanks@@ThinkingandTinkering
Hya Mate , long time , try Nitinol????
tried it mate - it's awesome - but this video is not about that really
Does it work in reverse?
yes if you wind it the other way - and i am being serious not facetious - that really is the way to do it
I love you man!
lol - cheers mate
Automatic heat valve
A mind in motion tends to enjoy the feeling of forward momentum.
lol - i like that - cheers mate
well buddy how many times!??? buy your self a good microphone!! audio sUcks
ah ah ah!!!yessss i will!!by the way a capacitor microphone must by perfect!!
👍👍👍
cheers mate
Sorry, the audio is so disturbing that I had to stop listening after a few minutes. Hope the comment at least helps ranking your video up.
Normally i say cheers from across the pond' brother from a different mother, mister from a different sister that allowed you keep a full head of hair.
However, you flew right over it, lol.
Air muscles are interesting. They have the potential to reduce alot of power storage requirements for various robotic applications. If to transfer pressurized air from left to right in concert via a timing circuit bridged to mercury switches, and of course for useful protocol, such as perhaps things like automated farming practices, or powered exoskeletons to help make people walk again, maybe even run.
Super lightweight and affordability in mind. You are no slouch whatsoever! Keep on rocking and inspiring others, apparently you are going to anyways.
Cheers from a fixer upper hobby farm that i may move away from soon in SW Ontario, though might even become a type of undercover cop for some world class local heroes back in Toronto, if everything goes well. There is much to do, and teamwork is how to make it so. -_-
Vulcan high5's \V/_
absolutely agree mate - good luck with it all - and cheers to you too lol
I think you need another microphone
i warned you it might be a bit ropey - this was done on my PC while i was on holiday - of course it needs another microphone
I find it hard to believe anyone would post a video of this quality in 2019.
very cool, your resistive ink & a solar cell or battery & a few other bits could make it work, be interesting to see how many whine about your microphone.
I know even though i warned them in the video lol
Would be nice to incorporate this in a long pipe with peltier modules and a blower. ;)
nice idea mate
Christ Bob you're as bad as me, go on holiday and just piss around in a garage somewhere new, bollards to everything else there! 👍
lol - it's a sad state of affairs mate lol
Lol, you weren't kidding about making us watch 5 minutes of you winding nylon.
lol - nope - but i did warn you in all fairness lol
