Ultra-precise, mind-controlled prosthetic hand for amputees via RPNI neural interface


[Background music] [Robotic hand closing] HAMILTON>>It brings you back to a sense of
normalcy. It’s like you have a hand again. CHESTEK>>Advanced prosthetic hands on the market
can do lots of things CEDERNA>>These are beautiful prosthetics
with incredible capabilities, but we’ve had no way to control them. CHESTEK>>To get that kind of control,
you really have to go to the nerves CEDERNA>>The problem with most of the technologies we have is that the signals are really tiny. You have tiny little peripheral nerve
signals and you have noise in those signals that’s about the same size. So
when you try to hear what a peripheral nerve is saying you actually can’t hear it. We designed a way to connect up with the
peripheral nerves with a piece of muscle and then what happens is when a tiny
little peripheral nerve signal comes down the nerve, it goes into the muscle and
it becomes a huge muscle signal. CHESTEK>>We’ve now seen to my knowledge the largest voltage recorded from a nerve compared to all previous results. That makes these
signals big enough that we can record them and interpret them for controlling
a prosthetic hand. HAMILTON>>It brought back into my mind the thought of: “well, if I had something like this I could actually be out working without risking hurting myself.” SUSSEX>>I think it’s a really good step
into the future. It’s a good way to move forward
for not only me but for other people. CHESTEK>>You can make a prosthetic hand do a lot of things but that doesn’t mean that the person is intuitively
controlling it. So the difference is the person
just thinks about moving. This worked on the very first time we tried it. So now we can access signals associated with individual thumb movement,
multi-degree-of-freedom thumb movement, individuated fingers, and this opens up a whole new
world for people who are upper-limb prosthesis users. [Chuckle] [Background music gets louder]

  1. Congratulations Paul….truly world changing work. It's awesome. The entire Michigan team deserves high praise.

  2. Is this Lab only or is it useable in real world? If real world, is it about to be released as a real prosthetic? How much might it cost? These articles always report something and then it fades away.

  3. It's so cool that this technology is finally making tangible progress. Once this matures and develops in scope, the lives of millions of amputees will improve immeasurably and we may even have people voluntarily "upgrading" their natural limbs for more agile, faster, stronger robotic limbs.

    Not only that but the technology could be adapted so that a person could remotely control a robot, say in a dangerous environment or space. A person sitting in a control room in London could plugin and control a full sized robot in the reactor at Chernobyl or in a mine field in Afghanistan. We end up fighting wars using these things as proxy's.

    It's like the past 50 years of sci fi stories are finally coming true.

  4. I'm confused, the video makes me wonder if he is just selecting among options to do a pre-made motor action, is he? I.e. pinch, grab, point. It would be more thrilling/convincing to see the hand do 25 different thingies in front of the camera (not with an object in the hand, just the hand itself doing abstract things instead of neat-n-tidy grasp/point/etc lol).
