LaChappelle taught himself robotics after meeting a 7-year-old who told him her robotic arm cost $80,000

Easton LaChappelle is only 19 years old, but the star of Uproxx’s new original series Luminaries is already doing bigger things with his life than many adults.

LaChappelle, from Colorado, taught himself robotics after meeting a 7-year-old girl at the state science fair who had a prosthetic arm that she told him cost $80,000. He’s refined his technique since he built his first prosthetic arm (with LEGOs, no less), combining 3D printing and open-source software to allow others to download and work with his designs.

“No one person can change the world,” LaChappelle says. “It takes multiple people, so if I can develop technology in a way so other people can take what I’ve done and grow from it and do something more with it, someone could take that and keep impacting someone else’s life and eventually try and rule out a lot of the bad in the world by giving back.”

Thanks for spreading the word, and more, Easton.
