HASEL actuators with muscle-like performance
Вставка
- Опубліковано 3 січ 2018
- The Keplinger Research Group at the University of Colorado Boulder has developed a new class of soft electrically activated artificial muscles, called HASEL (Hydraulically Amplified Self-healing ELectrostatic) actuators, which exceed or match the strength, speed, and efficiency of biological muscle. HASEL devices are powerful enough to lift a gallon of water, yet offer the versatility to perform delicate tasks like grasping small fruit or an egg. Also, HASEL can self-heal from electrical damage, self-sense position, and operate at high-speeds, all while being made from inexpensive materials like silicone rubber, hydrogel, and vegetable oil.

I'm a double amputee and this stuff really gives me hope. Keep it up.
This has the potential to make robots basically silent...that's incredible.
So they can easily kill you in stealth mode 😂😂
we're closer to government mandated mommy gf's
@@user-ro1cc8tz6d More like we're closer to work environments where automation doesn't require noise cancelling headphones which are expensive, fragile, and come up missing sometimes. It's kind of a game changer in the grand scheme of things, cheaper to operate robots means that the end product is cheaper for us so we're talking about cars that will cost a few grand less or more.
Robotics upgrades are major boosts to the economy. The more achievable a mass produced item becomes, the more will achieve it, which stimulates growth and research. It's a domino effect.
@@user-ro1cc8tz6d Yay
@@YodaWasSith You do know currency is subjective right? Work however is not. More robots, less humans. What will you do when you become obsolete in a world becoming overpopulated?
Damn, fleshlights are gonna be wild in the future
Exactly what I was thinking
This artificial muscle.. So impresive, its like real muscle, almost for movement and how it works
Its actually works the opposite than real muscle, as in the default position is contracting and stimulated position is relaxing.
The good thing about this is that it does not make annoying noises like servo-controlled actuators.
Great observation. This video speaks exactly to that. ua-cam.com/video/-Xpy8fsctWk/v-deo.html&ab_channel=ArtimusRobotics
I love how the fibers are joyfully laughing at 0:45

Artificial muscle : lift load, power off

When muscle receives ATP (energy) it stretches muscle fibers. A muscle that does receive ATP (energy) contracts and becomes rigid, it's the cause of rigor mortis in dead bodies.
@@raphaelnb1992 it doesn’t contracts, it just gets “fixed” in premortal position.
That's still fine as when you have an opposite working Actuator they allow for Movement in both directions
Good idea to make functional artificial heart.
Indeed.
How far has this technology progressed since the 3 years of the making for this video an also how much further do we have to advance to see real world applications?
ok kid. how much has you progressed in the last 3 years? exactly
They deteriorate quickly
@@apidas How much has your grammar progressed since your last comment?
@@konrah1486 😂😂😂

So they work similarly to the pseudo muscles of jumping spiders, interesting. They have great potential in speed and agility then.
I'm into this for use in medical care. So many kinds of injuries and diseases this could pretty much destroy: HASEL diaphragms for breathing, repair of amputees, maybe a good artificial heart could be made with this technology. Amazing!
This is amazing. Wonder if 3d printing can be used to print a muscle with hundreds of small cavities/electrodes to mimic our muscle fibers.
This is a very good idea.
Yeah good idea
Everything is possible. Except defeating COVID , LMAO.
No it cant, atleast not yet
@@ThatGuy-kz3fx your not that guy pal
Seem very effective!
My god, this is revolutionary. Why isn't everyone talking about this. This definitely needs a huge funding.
Not nearly developed enough to have any real practical applications
The strokers would simply be amazing
This is legendary! I will read your article!
Come on Algorithm, the one time I need you!!!
Wow! Really cool.
Thanks!
Sencillamente fabuloso!
awsm....I used to think such kind of actuators
I, for one, welcome our new squishy overlords.
Wow, technology is only like a stellar second from reaching the singularity.
No!! Too much to know. Too much to know. And we’re kind of busy dealing with climate change
Great stuff. I'd love to see a demo of a muscled robot walking with this.
There’s one already, I’m not sure of the video name, but try searching artificial muscle skeleton
It's nice to see companies doing things that will actually help humanity advance in many ways.
Great work
That’s incredible
Thanks
This is awesome because they could possibly make an artificial heart with it
If this is power efficient enough, it could be a better substitute for servos and actuators in artificial prosthetics
Nossa que DAORA mlk,
Whole humanity were created just to make this? Interesting.
No eggs were harmed in these tests!
Eggxactly
Looks cool but i imagine moving a gallon of water up and down is waaaay easier than just moving it up an keeping it there
Amazingly
This is cool.
Hi I'm doing research on soft robotics. I'd like to get in touch with such researcher community. Looking forward to get some tips. Thanks
I wonder if the fluid can be changednto ferror fluid then use magnetic fields to move it like here .
What is this creativity
That is some kind of cool. I am curious like another viewer, how has this progressed in 3 years. Bet that would make a very nice prosthetic arm. Deep sea explorers could use that to grip delicate samples.
Nice.. Bicentennial Man is coming closer to reality
Similar to rubber band spand and expand this I understand when I was a kid only now we have the technology to improve it.
The future of robotics lies with piezoelastic polymer muscle analogues. They will render all other robotic motion and strength technologies obsolete, and they are what you should be focusing on rather than this dead end technology.
With piezopolymer muscles, all that is needed is a control loop (since they would have position and force sensors in them, most likely) and power connections. No pumps, no gears, no servos, nothing but the muscle, its attach points, power, and data cables. Really straightforward, and capable of very efficient force generation with precise positioning control.
So is this, it also doesn't need pumps, just plates and a voltage. Just like piezoelectrics. It is also an electrostatic motor just like anything piezoelectric. Which means both require far more electrical energy per work done.
Also it can also sense its own position by either capacitance or stored voltage. Just like a piezoelectric element.
Hard for many to conceive, how genetics and mechanics actually link from worlds of two or more professions. These factors demonstrate on creating abilities from miracle recovery, to super species.
Use PWM signals for muscle movement range
Do you have a version that does not require electricity and works only with air or hydraulics ?
The miniaturized one was used for micropump ans thet call it bello type. It was made with PDMS.
That could be used as base layer for robot hands ..would feel soft and make the robot more life like
so what you need to remake this, ziplock bag (polyethylene) , aluminum foil strips, vegetable oil and a power supply, only thing is i don't know what voltage, i would guess it's fairly low, maybe like a tens system.
Voltage is much higher, in the kilovolts. Check out KeplingerResearchGroup.com for the academic papers which have the exact values. Operating voltage is dependent on material thickness as well.
@@tgmorrissey : have you folks published info on environmental capabilities, like temp, humidity, UV, et al ? A late-comer here ;-)
What you really need is a portable, high voltage, high capacity energy source.
Is this going to be use for robotics or people that have medical issues? its so interesting
Can I use this with my humanoid ?
This is like art imitating life, or is it life imitating art? This research really puts the idea of muscles into perspective in a practical and artificial manner. Animals evolved with muscles because it really is the best mechanisms, evolution is tried and tested. Great work!
Thanks Lance! Glad you like the work.
Hi, I'm a representative from the Cyberdyne Systems company. We are very interested in this product for its possible future application.
Archaic technology !
Super ❤️👍
What is the timeline to release technology like this for research into potential products?
Hi, Thanks for your interest. We have HASEL development kits available for purchase soon. Can you shoot me an email at Tim@ArtimusRobotics.com and we can talk about timeline and applications.
Cool
This would be great for creating mechanical splints for those suffering from tendinitis or carpal tunnel
Except for the tremendous voltages involved.
I can see this being used on exoskeleton
People could be aided to lift heavier objects
Exactly.
Electrorheological fluid?

How much does the artificial muscle contract
Reminds me of Westworld series intro.
0:45 when you realize your weener isn't for just to pee.
This probably can be used to lift containers to be transported on ships
That sounds like a big lift! ;)
Inb4 we have Boston dynamics building their robots with this
This technology will be used by adult toy industry. Hopefully.

What maximum power value is? Can it be stronger than human muscles?
It is the question isn't it... è_é
I can't wait until the age of super robots! It can only end really well👍
It sure looks amazing but I have a question: How much electricity does it consume? Would e.g. that Boston Dynamics humanoid robot be able to last longer with these muscles than with what they are using now?
Boston dynamics was fake
@@one1moreform who tf told you that
@@naomiwolf8944 Boston dynamics themselves
@@one1moreform holy f..
One of the weak points of these actuators is they require an extremely high (and unsafe) voltage to operate with good performance (kilovolt range IIRC). I don't think they actually require insanely high power though, just high voltage.
build robotic joints like knees elbows and put hooks on thees joint make som digital imput in to the joint that is attached to the upper arm and lower leg
i dont know how long will it take to use this as artificial muscles for humans but its pretty sure that we can see robots with these muscles which will make robots silent and more agile
Lol this is pretty cool but I shudder to think of the voltages and energy involved.
Hello im working on a robot and would like to implement your tech into the machine to help with articulation of limbs. What voltages are these actuators working on. Where would someone reach out to procure these if one did not want to make them. Thanks in Advance.

Tens of kilovolts..
Can it replaced maybe the heart?
someday!
I love the advancement here. I'm not a scientist but you have no idea how much of my brain and daydreams are spent trying to think of ways to make humanoid style robot muscles. Can I ask.. Is the oil itself reacting to the electrodes or is it that the electrodes are attracted to each other when voltage is applied, causing a simle liquid displacement? The news artilces made it sound like the liquid spasms, but from the video here it looks like the liquid could almost be anything. On the other hand the "self-healing" description makes it seem though as if the liquid itself is also reacting.
Liquid displacement...the self healing is the elastomeric coating being healed by the fluid drying around the leak and hardening/sealing upon exposure to air (from what I can tell).
Are you using Silicone Dielectric Grease? If so how do you control for the arcing (if any) which usually results in silicone carbide buildup? Also in the planar hasel whats in the middle, is it the same as the liquid filled pouches? When you show the capitance resistance for the bicep are you using matlab? How are you getting it to apply more voltage when resistance is met? If its in matlab can you upload the file?
Thanks for the questions. You can find out the answer to all your questions in the original text and supplement found here www.keplingerresearchgroup.com/publications.
No dielectric grease is used. No arcing issues. When the device does short through the liquid dielectric, the liquid simple redistributes and the device continues to work.
The liquid in the planar HASEL is a commercially available dielectric fluid, full details in text.
Capacitance is measured with a custom LabView VI based on phase and amplitude shift between voltage and current of the device. See the supplemental for those details.
Unsure what you mean about applying more voltage when resistance is met. Please clarify questions if still confused after reviewing the supplemental discussion on capacitance measurement.
Glad you appreciate the work. Best - Tim Morrissey
In one of the interviews was mentioned that this technology will be opened to the community. Do you have a licensing program?
I am doing a university project for the end of my degree in which I move a knee prosthesis with this technology but I am running into some problems,
Could I know what liquid they use in the elastomer?

What is that hasel muscle made from at @0:10 ? As I think an awesome arduino project is coming to mind...
I mean... Just stick a fleshlight at the bottom of the jug there and...
Is that using castor oil?
great questions. This is using, vegetable based transformer oil, but castor oil would work too (castor oil is a little viscous which hinders performace) you can find more info on our groups website, links in description above.
Is Westworld coming?
We have acoustic levitation
Just can't leave well enough alone, can youz.
Is it possible to do a DIY version of this? Or is the voltage too high or something?
You could. the problem is the materials are all one offs, it seems. That is, you need to design adn produce your own DEA (Dielectric Elastomer Actuator) material. I really want to work with this stuff, too, though, so I feel you.
Do a search in UA-cam about it I already found a Ted talk who shows how to.
Holy shit this was 3 years ago whats the progress?
Great for people with disabilities
Oh, so they are trying to make LIFE
Heart pumps?
Oh, but you can't control the strength
Please make a robo-gina
How would you build this?
You grow it?
Hey Philip, The academic papers discuss all the steps to make these, available here: www.keplingerresearchgroup.com/publications.

Good work glad someone thinking.
Sweet now all we need is GM to build a portable fusion reactor and then...battlemechs.
1 step closer to terminators
It's seems so obvious, now that I've seen it, that an electric motor could move liquid rather than solid (although the skin of the bags are solid in this motor.) Quite an interesting accomplishment. I'm sure it will find a place in the wide world of electric motors. How quiet is it? Can you include a video with sound? Nice to see it can also be a servo.
With all due respect, the definition of an electric motor is "an electrical machine that converts electrical energy into mechanical energy" which describes this machine accurately.
This system is based on electrostatic principles and is very quiet, no spinning fans or anything to make noise. The only noise it makes is if it operates so fast it acts as a speaker.
Thanks. I see someone mentioning that voltage is an issue. I guess for any consumer application you would need to get this down to 110 volts A/C. You don't have to tell us how soon that will happen, but can you give a hint/clue as to whether it's in your plans?
You can use small amplifiers like these here, that run from a cell phone battery: www.emcohighvoltage.com/proportional/agseries.php
Thanks. Interesting. Hmm, this is a DC converter. I had assumed we were talking about AC here. My mistake.
So basically it has a plastic membrane. Filled with a quick dry fluid for not self healing probably more akin to self patching. And compresses via electromagnet.
we can make silent drone with this
We need durability
