Young engineer upgraded the LEGO bionic arm he built for himself


Bioengineer David Aguilar (aka "Hand Solo") continues to upgrade his DIY LEGO prosthetic arms that we posted about previously with this fantastic fourth generation model. From Reuters:


All the versions are on display in his room in the (Universitat Internacional de Catalunya) residence on the outskirts of Barcelona. The latest models are marked MK followed by the number – a tribute to comic book superhero Iron Man and his MK armor suits….


After graduating from university, he wants to create affordable prosthetic solutions for people who need them.


"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?"
