We were just talking about the incredible i-Limb hand the other day—a bionic hand controlled by nerve impulses—and here is one of its first videos in motion. We love when the dreams of science fiction becomes the reality of science fact...especially when it doesn't involve robots exterminating the human race. [medgadget]
From what i understood from the video, it recieves its input from two muscles existing in the users arm, which are then somehow translated into what the user wants the Cyberdine hand to do. I don't think it uses brains impulses, but good ol' fashioned mechanical (i.e. push/pull) input.
