David Aguilar from Andorra entered the Guinness Book of Records in 2017 for the world's first functional prosthetic arm
Aguilar himself was born with Poland syndrome andan underdeveloped right hand - instead of a forearm, he has only a partial fingerless hand. However, his condition did not prevent him from becoming an inventor. He says that because he was missing an arm, he was bullied at school as a child. At the age of nine, he assembled his first prosthesis from LEGO, and at 18 he made the design perfect. Today he is studying to become a bioengineer.
He named the mechanical prosthesis MK-I afterIron Man's Mark 1 costume from the comic book series of the same name. The first hand prosthesis had an elbow joint and a clasp to pick up objects that the user could work with while bending the elbow.
