We currently have certain prosthesis's that we can control using our nerves impulses and synthetic muscle fibers, and many people have them, they come in eyes, hands, and ankles. Too bad they cannot make them complicated like an entire leg or entire arm because of lack of technologies and cost, which would be overwhelming. One example of this prosthesis is the AEKP, which is a prosthetic lower half of the leg, which is controlled by nerve impulses.
