Lego Prosthetic Arms

posted by Jason Kottke   Feb 12, 2019

19-year-old bioengineering major David Aguilar, aka Hand Solo, has built himself a series of prosthetic arms out of Lego. In this short video, he shows off some of the arms, including his latest 4th generation model:

He built his first Lego prosthetic limb when he was 18. According to this Reuters article, Aguilar names his arms using the same system as Iron Man uses for his armor suits (MK-1, MK-II, etc.) and wants to build low-cost prosthetics after he graduates from college.
