Question: is it possible to build artificial muscle using household items?
Hypothesis: if polyethylene fishing line is coiled tightly, then it will be able to condence when heated because the tight coils will try and unwind when heated
Hi my name is anders and I have always loved the idea of exoskeletons, robots, and petty much anything that moves mechanically. Exoskeletons especially, they always seemed to be the coolest. The idea of being able to run faster, jump higher, or even lift a car above your head is awesome. One of my dreams is to be able to build one of these exoskeletons to do all those those things (besides lifting a car above my head, probably not going happen), so I've been doing quite a bit of research. I've looked into hydrolics and motors, but both are big and bulky and a bit out of my price range. I kept looking, and looking until finally I found something that would work, carbon nano tubes are ultra light and very small and compact, they are also extremely strong. Why does this matter? the university of Texas, dallas recently discovered that carbon nano tubes contract when an electrical current is passed through them, quite ingenious if I do say so myself. There is one problem with carbon nano tubes though, they are very difficult to make and aren't being sold, at least not to my knowledge. There I was back exactly where I started, square one, no other way to go, so some time went by and I went on YouTube and typed In "artificial muscle" and in the auto complete section below the box it said "artificial muscle fishing line", curious I clicked on it and found a pretty interesting video that I decided to watch it was an animation of a line being spun until it sarted forming coils, then it showed it stretching and then contracting. I watched some more videos and found out that these are extremely cheap and easy to make, assuming you've used a drill before. I also found out that their contraction strength was stronger than carbon Nanotubes and they were a hundred times stronger than a human muscle of equivalent size which is awesome. Another thing I learned was that they were made by the same university that makes artificial carbon muscles, this was very exciting for me because a would now be able to build these, and build a cheap exoskeleton at my house (if I can find the time).
Why did I build this and put it on instructables? The reason I built this was because there wasn't very many sources to get the info on how to build this. I also made it because I wanted to build a cheap, but effective replacement for motors and hydraulics.
Thank you for all your support, and tips to help me improve my instructables. Without you guys I wouldn't be doing this right now, you should expect many more indestructible in the future so don't forget to subscribe to me and/or favorite this instructable. If you have any question or concern then be sure to comment, or if you just want tell me how awesome this is that's fine too. Here it is, hope you enjoy it. Don't forget to vote for me, thank you.
