I finished the joystick and sold it to researchers who used it in an MRI machine to study human brain function. This is what I did in my previous business.
Well, 5 years old vid, but whatever. I know for sure you could increase the air muscle contraction per cm by using a different braided wire loom. I think a thinner braided wire loom, made for a wider diameter would work. You then stretch the wider braided wire loom so that it becomes longer, but more importantly, that the braiding becomes more elongated towards the length of the pipe. That way I believe you could double or triple the range of motion. There is a limit on how thin the braided wire loom can be. The limit will be when the silicon pipe begins to bulge on the gaps of the braided wire loom. Also doing this that I am suggesting you might reach another limit that is how much the silicon pipe can stretch sideways. High pressure thin bike tubes might work too, for a larger muscle.
the travel is related to the 'openness' of the fiber weave, and the difference between being fully stretched lengthwise and fully expanded width-wise, and that also influences the actual strength of the muscle, which means that a muscle with much more travel is possible, but it would be weaker and have to run on lower pressure to prevent a "blow-out" where the tubing will slip between the fibers of the weave. The opposite is true, you can have extremely strong ones with very little travel.
10 years ago.. wow time flies. i feel like i watched this video just recently when it came out.. your production quality did noticeably increase over that time period though :)
You video cleared up a lot of problems for me. I need something like an air muscle for an idea I have ...Could you tell me where you got the joystick you used in the video? THanks Dave
Hi, I'm currently working on similar school project and I would like to know where did you find a joystick pivot like this. I'm struggling to find one that works well and is entirely in plastic. Thank you
Great vid! but I am also planning to build using similar materials, but where did you find that voltage to pressure transducer? I was originally going to make my own :P but seeing that nice unit makes me want to buy it! It would probable work much better than my own would
Did the same thing a few months ago! Had no problem lifting a full can of paint and even an old car alternator!!! Dude your vids are awesome! Your so stinking smart! You may have a use for this touch sensor device I came up with! Check my channel for a vid on that!
Hi Ben! What can you say about my version of an artificial muscle? SL_ST AIR MUSCLE has uploaded a model to GrabCAD. It has an increased working stroke. And it can also be typed into a chain, which will only increase the effort being developed.
Hi Ryan, Do you know research papers about the strength and contraction relations in pneumatic artificial muscles? Or is there another source to learn more about their characteristics? It seems you know some facts about them. I am doing experiments on them in our lab.
Hi - I loved the video. I am trying to find a pneumatic system to look into that will do proportional control. The idea is airlons will move with a joystic (like a rotary control valve in a power steering rack). Does anyone here know of which components I should be looking for?
nice vid very cool but i think il stick to my 180 PSI or my 260 PSI pneumatics (they are very big) also for the small stuff i cant just use a pneumatic with single input and spring actuated return (10-20 PSI and very nice for the small stuff)
Hi- I absolutely loved this video of yours, it helped me build the air muscles with ease. However Ive been wondering how I could "power" them with something a little more portable. Any small air tank or compressor you know of that could help me with this?
I really enjoyed watching but a pneumatic force feedback joystick, seriously ? If it's just an experiment it was fun to watch, if it's intended as a production prototype do keep us updated on how you'll make this work (after 2 years I'm guessing experiment)
Interesting issue. I am not that smart, but did get idea for use, very early in concept. Have a older player piano , need to up grade the air system with new hoses . This might be a possibility for the new hoses , instead of just rubber. THANKS geo
It looks like all the weight is suspended on the hose barb, and I didn't think they would support a lot without pulling off. Have you experienced this failure, and if so, about how much weight were you lifting when it happened?
Can you please share where you got the parts at? I wish you had stated where to get them in your video or atleast on your blog posts but I can't find anything indicating that. Can you please make a parts list with a link or store of where I can get them? Thanks!

Applied Science so you use arduino in commercial products?

Take a look at the Saitek entry-level joysticks. I believe they currently call it the Cyborg V1
excellent, very well made video. I look forward to seeing what happens with the manifold when you're done!

Excellent and thanks for the reply, really appreciated.
Fantastic! Now when I am in an MRI I can play some video games!
Very cool, I like how simple it is.
He just did... that's what an air muscle is. All you have to do is figure out how to hook it up to whatever you want it for.
at 5:33, how much psi were you putting into the muscle? you said earlier that it was around 10-30 psi, but that was without the mesh sleeve.
Loving it!

That's how spiders extend their legs
The muscles might be cheap but how much is the pump and control bock, especially if you want prop control.
Did you ever finish this project?

remember the link to where i can find that type of air manifold with those outputs you talked about @8:46 ?

Awesome
hi can you tell me how much air would it take to make this work and how long will this air last for

I don't know if you noticed, but he posted a comment saying that he sold it to researchers who study brains with MRI machines.
if you use a bigger loom it will be better
Interesting issue. I am not that smart, but did get idea for use, very early in concept. Have a older player piano , need to up grade the air system with new hoses . This might be a possibility for the new hoses , instead of just rubber. THANKS geo
Can you build a DIY linear actuator, please?
It looks like all the weight is suspended on the hose barb, and I didn't think they would support a lot without pulling off. Have you experienced this failure, and if so, about how much weight were you lifting when it happened?
Genius!
Hi, im working on air-muscle as-well, i would like to know which air-pump did u use, and how much bars would it provide,
oops i ment "can just use" instead of "cant just use"
Can you please share where you got the parts at? I wish you had stated where to get them in your video or atleast on your blog posts but I can't find anything indicating that. Can you please make a parts list with a link or store of where I can get them? Thanks!
Check the description. I provided my own sources and part numbers, as well as a link to an Instructables page with different sources.
Is there a smaller voltage to pressure transducer? say, for mobile application?
i am goin to try this for my robot arm :)
how smart....
what mechanism is used to control the movement of air into the muscle
A compressor.
OHHHHHHHHH BURN.
