Ok, so... I know this is just a touch ambitious... but ultimately I'm trying to build a relatively simple exosuit, the main code of which would reside in Arduino. It would only have essential joints like knees, hips, back, shoulder elbow, and maybe some others, and I figured piston movement would be best to power them (please correct me if I'm wrong on that)
I did some research, and I think hydroulic might be best since it is extremely strong, can be fast, and I think it can be relatively accurate. The only question I have about that is where I would put the water source and how to use it... a link to an article on this would be really helpful.
Originally, I was going to go with pneumatics, but apparently accuracy is difficult with those and so is mobile air compression. Otherwise they would be great though, so if anyone has something on that...
Another option I found is motorized linear actuators, but I'm kind of worried that I would have to pick 2 between strong, fast, and accurate. If anyone has a way around this, that would probably be the best thing to use because it's much simpler than hydroulics and only requires a battery (and some fairly simple circuitry to get it hooked up to Arduino) to operate.
It'd be really nice if I can find something that doesn't cost much, but if not then until I get a job I'm mostly just looking at proof of concept anyway :P Thanks in advance for your help!
