Man Controls Cybernetic Hand With Thoughts

MaryBethP writes "Scientists in Italy announced Wednesday that Pierpaolo Petruzziello, a 26-year-old Italian who had lost his left forearm in a car accident, was successfully linked to an artificial limb that was controlled by electrodes implanted in his arm and connected to the median and ulnar nerves. He has learned to control the artificial limb with his mind. According to CNet, Petruzziello says he could feel sensations in it, as if the lost arm had grown back again. The BBC has a brief video showing the arm in operation."

    At least we now know the identity of Dr. Claw and why he was able to leave his arm with a bomb in an armchair like in the intro. But will Gadget ever figure it out? Probably not.

    C'mon, that's terrible even by my standards!

      You have to hand it to them though, I think they really pulled it off!

    Looking at the video and articles it seems they haven't integrated the whole thing into an artificial hand attached to his arm. The hand he controls is shown separately from his body. Perhaps the unit is too heavy at the moment.

    So Ratz can't have his russian military seven function force feedback manipulator just yet.

      Sounds like the purpose of the test was to test the actual electrode interface and how complex the hand motions could get with it. The duration the electrodes stayed in his arm is the important part. With this test it seems complex cybernetic limbs are basically a done deal. The question is whether or not they can actually hook them up long term without serious rejection problems.

    Like, will it still count as masturbation if he uses the cybernetic hand?

    And, can they give you control without feeling sensation? Because that would totally feel like somebody else's hand...

      No, he still gets sensation. That's actually a technology that's been around for a couple of years, now. The nerves that used to go to the tips of the fingers are surgically relocated to convenient locations where the prosthetic will be mounted, and appropriate sensory devices are built into the fingers, which in turn, relay that sensory data back to the appropriate nerve endings. The net result is that the person wearing the arm gets the distinct tactile sensations from his missing limb, via the artificial limb.

      One of the things I find interesting about modern prosthetic limbs, is that the advanced models can actually have the ability to react to nerve impulses faster than the user's real muscles.

      Without sensation? Seems dangerous. What if you squeeze too hard? Pull too hard?

      ah, they can rebuild it. they have the technology! in other news: OUCH!

  5. Optional extras by Geminii · · Score: 5, Interesting

    Could be interesting to outfit it with PDA/smartphone/net capabilities linked to a couple of extra feedback wires. You'd be able to develop electronic senses such as orientation, absolute location, driving directions to a destination, knowing when someone had sent you an email, and the direction and distance of practically anything with a Whitepages/Yellowpages entry.

    For bonus points, equip your car with a GPS+intertial tracker and cellphone, and you'll be able to find it anywhere on the planet to within a couple of dozen feet. Add in a radio transmitter which can pick up and replicate signals from things like car keys, and you'll be able to find it within that dozen feet, too.

    I'm thinking - what about being able to put the hand into virtual mode, so that wrist and finger gestures aren't expressed by the mechanical hardware but are instead used as input to an interface linked to a bunch of macros for the electronics? Add an IR transmitter/recorder, point at the TV, go virtual, and sign the macro for switching on, calling up your favorite channel, and turning up the volume. Or with an IRDA channel, be able to send macro signals to your PC to do whatever you want. Heck, go the whole hog and install WiFi, Bluetooth, a USB port, an acoustic coupler... you'd have the most connected hand on the planet!
