Feb. 8 (UPI) -- A Spanish 19-year-old born with only one arm said his childhood love of Lego led to his building a prosthetic arm out of the company's pieces.
David Aguilar, who is studying bioengineering at Barcelona's International University of Catalonia, said he has been tinkering with Lego inventions since he was 9 years old, and the hobby led to his developing a Lego prosthetic arm.

Aguilar, who goes by "Hand Solo" online, said he built his first arm when he was 18 and he now has several versions with a variety of functions.
He said the arms contain small motors inside to help the elbows and hands function like a biological limb.
Aguilar said he is studying to design low-cost prosthetics for people unable to afford more expensive limbs.
