Full biography of David Aguilar

David was born without a right forearm, affected by Poland syndrome at the age of 9. Ever since he was a child, he was obsessed with Lego.

He spent his childhood building cars, planes, helicopters, and eventually, his own prosthetic. The self-named “Hand Solo” decided to take his Lego-building skills to the next level. At age 18, he perfected his designs with the MK2, made out of a lego airplane, a prosthetic arm with the ability to bend and pick up objects with a pincer-like grip. Later, he dissembled a lego helicopter to build his 100% functional arm prosthesis.

He became part of the Guinness World Records as the first fully functioning LEGO prosthetic arm built and worn by him in 2017.

David is currently studying Bioengineering at the UIC (Catalonia International University) (UNIVERSITAT INTERNACIONAL DE CATALUNYA), where he was awarded the Innovation Prize in 2018.
