Man builds prosthetic arm from Lego

David Aguilar, a 19-year-old student in Spain, has built himself a robotic arm using Lego.

The student from Universitat Internacional de Catalunya in Spain was born without a right forearm due to a rare genetic condition.

He’s self-sufficient without an artificial arm, but wanted to build affordable robotic limbs for people who need them.

In 2017, he built a red and yellow robotic arm out of Lego pieces, with an elbow that bends and a grabber that flexes.

It’s called MK I — just like Iron Man’s first suit, which Stark calls Mark I.

Aguilar has since upgraded MK I with three more arms, his latest this year — colored an Iron Man-worthy red — called MK IV.

In the below video, Aguilar explains how the blue MK II works with a Lego engine and a fishing cable fixed to the limb.
