Teen with rare condition uses Lego bricks to build ‘Iron Man’-inspired prosthetic arm

Teen builds his own prosthetic arm out of LEGO bricks

A teen in Spain has combined his love for engineering and one of his favorite childhood toys to create a prosthetic arm.

David Aguilar, 19, from Andorra, a small principality between France and Spain, was born with a rare genetic condition that caused him to be missing his right forearm.

“As a child I was very nervous to be in front of other guys, because I was different, but that didn’t stop me believing in my dreams,” Aguilar, who is studying bioengineering at the Universitat Internacional de Catalunya in Spain, told Reuters.

The teen, who built his first robotic arm out of the plastic bricks at the age of 9, has since created multiple versions -- each of which have an increasing amount of functionality.

“I wanted to ... see myself in the mirror like I see other guys, with two hands,” Aguilar said.

He told the news outlet he hopes to one day use the creations as a way to provide affordably priced prosthetics to others in need, though noted he rarely uses the “Iron Man” inspired prosthetics because he is “self-sufficient without it.”

“I would try to give them a prosthetic, even if it’s for free, to make them feel like a normal person, because what is normal, right?” he told Reuters.

Aguilar frequently features his creations -- which use a small motor to help with movement in the hand and elbow joint -- on his YouTube channel called “Hand Solo.”
