In 2017, David Aguilar (Andorra), aka "Hand Solo", created the world’s first functional LEGO® prosthetic arm.
The news of his Guinness World Records title reached the parents of Beknur, an 8-year-old boy who doesn’t have developed limbs.
They contacted David and asked for a LEGO® prosthesis for their son, to help improve his autonomy. Upon hearing Beknur's story, David decided to make not just one prosthetic arm, but two!
