the hands when you were using them on friday and doing all kinds of things, cutting fruit, vegetables, picking up small things. how do those hands work? well, it s very crazy. i don t really know the indepth details. there are two electrodes on my foreman, one on top and one on bottom. and what i m basically doing is bending my wrist forward and bending my wrist back or what, you know, i feel is my wrist. and this gives signals to the hands to open, so there i m bending my wrist backward and close. bending my wrist forward. and then there is also some different things i can do with the muscle signals to actually change the grip to do a pinch mode or some different finger configurations. some people think you press that hand it will look like a prosthetic. it looks like you have a gray glove on. i mean they re perfect. absolutely. yeah. the technology today, i mean it s the most realistic looking hand out there.
