Building a Prosthetic Arm With Lego

Ever since he was a kid, David Aguilar was obsessed with Lego. He spent his childhood building cars, planes, helicopters, and eventually, his own prosthetic. Born with a deformed arm, the self-named “Hand Solo” decided to take his Lego-building skills to the next level. At age 18, he perfected his designs with the MK2, a prosthetic arm with the ability to bend and pick up objects with a pincer-like grip. Now, he’s the coolest kid on the block.
