Combining a Nintendo Power Glove with 3D-printed parts, 17-year-old Easton LaChappelle has designed an incredible robotic prosthetic arm. Made from LEGO bricks, fishing wire, and surgical tubing, LaChapelle’s robotic arm earned him 3rd place in the Colorado Science Fair of 2011 – which inspired him to go even further with the 3D-printed design.

    How could I find out information to possibly buy one of these for a 12 year old boy who will have to amputate his arm bc of cancer this week. He lives in Spain.

    Hey! This is an amazing project. Im writing from Chile, and i see that you reached your goal in Kickstarter, Congrats!
    My question is…will the design be open source?

    Do you currently have a kickstarter campaign up? And if so how do I find it? I work for a Prosthetic Firm in South Africa and we are always looking for more cost-effective ways to make prosthetics that are more readily accessible/affordable for those that can’t afford them. Great job, super impressed!

    Who got first place? Aside from that girl who sent her hello kitty doll to space, I can’t think of anything more awesome than this for a high school science fair.

    Hi Luke. The Kickstarter project isn’t live yet, but we’re working on getting the video done. I’m Chris Chappell and I’ve been working with Easton on this project. I’ve been designing the 3D printed parts. More info can be found at
