Inventor builds Lego arm for eight-year-old
In 2017, David Aguilar, aka "Hand Solo", created the world's first functional LEGO® prosthetic arm. David's latest MK-V LEGO® prosthetic arm is motorized, with five fingers that he controls by making subtle movements of his residual arm. David is on a one man - and one hand - mission to make his LEGO® prosthetic arms widely available to all those in need. The main challenge David faces when building prosthetic arms is balancing functionality and comfort. David provides free instructions on how to build the MK-V LEGO® prosthetic arm on his YouTube channel Hand Solo.David has big plans for the MK-VI and beyondDavid has lots of ideas for future prosthetic arms. One of David's biggest inspirations is his father, who always supported David's dreams. David is also telling his story through educational comics for kids and an upcoming documentary, titled MR. HAND SOLO.David's Guinness World Records title was just the beginning - he plans to build more prosthetics, inspire more people and keep helping those in need.
