Teen who was born without a right forearm builds his own robotic prosthetic out of LEGOS

David Aguilar has built himself a robotic prosthetic arm using Lego pieces after being born without a right forearm due to a rare genetic condition. Aguilar, 19, who studies bioengineering at the Universitat Internacional de Catalunya in Spain, is already using his fourth model of the colorful prosthetic and his dream is to design affordable robotic limbs for those who need them. Once his favorite toys, the plastic bricks became the building material for Aguilar's first, still very rudimentary, artificial arm at the age of nine, and each new version had more movement capability than the one before.

'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 from Andorra, a tiny principality between Spain and France, told Reuters.
