Remember the autofitting jacket from back to the future two?
My friend and I are building a functional one for our senior engineering project. We've narrowed down the solutions to servos and cables or hydraulics. However, both of these are rather bulky. Any suggestions on what else we could do or more idealy how to shrink these systems? We we're thinking about using muscle fibers to contract a bladder instead of a pump for hydraulics, but that would be expensive and annoyingg to implement.
