David Aguilar has built with LEGO since he was a kid. At nine years old, he built a prosthetic LEGO arm to augment his underdeveloped right arm, but the LEGO pieces weren’t strong enough to meet the needs of his design. Now at age 18, Aguilar has designed and redesigned a sturdy LEGO Technic limb with a pincer-like grip. It was assembled with parts from his LEGO Technic Air Race Jet 42066 Building Kit.
Great Big Story features Aguilar’s awesome LEGO Technic prosthetic arm and story in the video above. Aguilar also introduced his MK-II prosthetic arm on his Hand Solo YouTube channel in February 2018:Next: Boy gets prosthetic hand made by 3-D printer, a prosthetic system that lets kids make their own LEGO robot limbs, MetaLimbs, extra robot arms that you control with your feet, and more videos about prosthetics.
