17-Year-Old Creates a 3D-Printed Robotic Prosthetic Arm for $250

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.

At the Science Fair, LaChapelle encountered an entrant who wore an $80,000 prosthetic arm that would need replacing as she grew. Inspired and intrigued, he decided to take his homemade robotic arm, which could only grip a soda can, to the next level. His new goal was to create a high-tech prosthetic arm that was not only highly functional, but also affordable.
