Colorado Teen Designs Robotic Arm With 3D Printing 68

Posted by samzenpus from the best-science-project-ever dept.
coolnumbr12 writes "A Colorado teenager has used 3D printing to create a robotic prosthetic arm that is fully functional and costs less than $500 to make. At TedxMileHigh in Denver, Colo., 17-year-old Easton LaChappelle demonstrated his robotic arm, and how he constructed the arm to keep costs low. 'So in the end, I built this robotic arm up to the shoulder which was extremely strong,' LaChapelle said. 'It could toss balls to you, it could shake your hand, it could pretty much do anything a human could if you program it correctly.'"

      You have no idea WTF you're talking about.
      Generic "zomg too much regulation comments" almost always get upmodded and are almost always full of shit.
      Prostheses are more or less exempt from any FDA regulation that would make them expensive.

      (b)Classification. Class I (general controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter, subject to the limitations in 890.9. The device is also exempt from the current good manufacturing practice requirements of the quality system regulation in part 820 of this chapter, with the exception of 820.180, regarding general requirements concerning records and 820.198, regarding complaint files.

      Sec. 890.9 Limitations of exemptions from section 510(k) of the Federal Food, Drug, and Cosmetic Act (the act).

      The exemption from the requirement of premarket notification (section 510(k) of the act) for a generic type of class I or II device is only to the extent that the device has existing or reasonably foreseeable characteristics of commercially distributed devices within that generic type or, in the case of in vitro diagnostic devices, only to the extent that misdiagnosis as a result of using the device would not be associated with high morbidity or mortality.

      There's someone, somewhere, who had to spend money for the FDA to approve the first brain--computer--limb interface, but after that, everyone gets a free ride.

      Yes. And additionally, he's looking to use a paltry 10-channel EEG to do it. That may be enough for someone with good (and conscious) concentration to move one axis back and wards, and maybe even switch between axes. But moving the arm unconsciously and naturally? No way. Not even close. For that, you need some sort of nerve reinnervation, direct patch-clamping of the motor neurons, or an intercranial BMI (Brain Machine Interface) right in the motor cortex. Or you could sit inside a noninvasive MEG (Magneto

    Every time I hear someone say that artists won't create without being paid. That's a lie. It's the publishers who want to be paid. Artists just want to create and not die of starvation but artists don't need to be paid -- they can get jobs too.

    This guy is an artist. A brilliant artist, but an artist just the same. He doesn't just engineer things. He creates things.

    My heart will sink when I see some giant company snatch this guy up and the things he makes get marked back up to that $80,000 mark again.

    We see what's wrong with the world and "the system" (we say the system so we don't have to blame people directly right?) and we just go on without saying anything about it. I hope people start saying things. You don't have to do anything -- just say something. Say something to businesses out there. They might ignore you or me, but they won't ignore everyone -- they can't.

    Change the world. Just say something.

      The problem is always framing it in what the artist wants. Well, I'm sure my bricklayer/plumber/carpenter/electrician would love to get paid for the houses they built the rest of their lives, but they settle for a one time payment. We know what the artists want, they want as much for themselves as they can get while being able t

    I'm so sick of the press' obsession with 3D printed guns. Almost as sick as I am of my fellow American's infantile obsession with things that go "bang!". Maybe fireworks should be legalized everywhere so that people can get their dose of "bang!" without having to resort to flinging bits of metal through the air at lethal velocities.

    • Maybe fireworks should be legalized everywhere so that people can get their dose of "bang!" without having to resort to flinging bits of metal through the air at lethal velocities.

      If modern fire management practices didn't boil down to "let's pretend that this will never, ever happen" then that might make sense. But instead of burning EVERYTHING regularly, we burn selective areas to try to make firebreaks, leading to massive buildup of combustibles. One thing the natives really had right in the American West was the yearly burning, which kept forests healthy without burning down by clearing the understory.

  • Did he design it with 3d printing or did he use 3d printing to create it?

    make up your mind

  • As an engineer I think this is a big step I have not seen before. With easy access to 3D cad and low price 3d printing hopefully the term design engineer will be a thing of the past. Normally this robot would have to be properly designed for injection molded and machined parts. With 3d printing all of those constraints go away. I would define my job as designing around the constraints of a particular manufacturing process. 3D printing has very little constraints and uses low energy. I think that is ca
