As a child, David Aguilar, used to love playing and building things with Lego. Now at 19 years old, he built himself his own prosthetic arm using Lego pieces powered by an electric motor. 

Because of a rare genetic condition, Aguilar was born without his right forearm. Ever since the age of nine, he has been experimenting with creating different versions of artificial arms using his favorite plastic bricks, and has since made three versions from the very first one he started on, that have become more innovative than the previous. 


“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. I wanted to … see myself in the mirror like I see other guys, with two hands,” Aguilar, who is originally from Andorra, a tiny principality in the Pyrenees Mountains located in between Spain and France, told Reuters.

This inventor, who is now studying bioengineering at the Universitat Internacional de Catalunya in Barcelona, Spain, is now using his fourth, most improved prosthetic lego arm occasionally, as he is also self-sufficient without it.  Once he graduates from University, he dreams to have the opportunity to design affordable robotic limbs for all those in need. 


According to the World Health Organisation and World Bank, around 1 million people in this world, with 80% of them living in underdeveloped countries live with this disability, and more often than not, they have no access to affordable care that they need. “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?” Says Aguilar.
