    I've been interested in Terminator like robots for a long time, I wanted to create a utility robot that can do everything and more a human can do. There are a lot of really advanced and organic like robot limbs out there, all though their all mostly not efficient in terms of energy use. I would like to propose the idea of using hundreds of cylinder shaped balloon fibers that would imitate muscle fiber. The cylinder shaped balloon fibers would contract by a volume being evacuated from the balloon creating a vacuum thereby contracting the muscle fiber, and to relax. The muscle fiber would be injected with a liquid volume adding internal pressure to the balloons and causing expansion of the balloon. To control the amount of contraction and expansion, the fluid can either be injected at a certain rate, or ejected at a certain rate. In conjunction with this system the muscles fibers would be exposed to positive atmosphere through means of fluid, there by increasing the strength of the contraction and enforcing the need for higher pressure fluid injection, creating a a overall strong muscle. I speculate that the required amount of fiber lines could be 25-100 and the amount of fiber in each line could number in the hundreds, of course small balloons would be needed, so as to not have a arm muscle that is as big as a door. The muscle fiber would need to be as small as a needle and fluid injection tubes would have to wrap around the muscle fibers like veins on real muscle, the tubes would number in the hundreds for each individual fiber.
    the only energy required would be to power pumps, which I believe is a lot cheaper and more efficient then just using powerful electric motors.

    You know there already are artificial muscles that work this way on both fluid and gas, right? They even combine multiple tubes to form one muscle. Are you saying you are bringing something innovative to this idea? Perhaps by increasing the number of tubes and decreasing their size? The ones we have now are rather large tubes, with something like 10 tubes forming any one given muscle.

    I have always been interested in pneumatic muscle and muscle wire, but both have extreme limitations. Muscle wire heats up and bundling it together into an actual muscle doesn't work very well. Also they make it hard to implement fine motor movements. Pneumatic muscles give great fine motor movement control (and also strength), but require bulky and energy-hungry air/ liquid compressors to run them.


    It is by will alone I set my mind in motion.

    it got a like, a dot is meaningful input. '

    It's nothing special, just the idea of shrinking and using more fibers, don't know why robots are using 4 large fiber for a muscle, when it's clearly possible to imitate a organic muscle, by using more and smaller balloon fiber, and then shape it accordingly cause it would be flexible.
