Thanks to melopoeia who sent me this link, I just now learned about Kaylene Kau’s prosthetic arm designed for people who have amputations below the elbow. Its tentacle-like design simplifies the usually complex design of manual prosthetics, resulting in an appendage that requires fewer parts and motors than most arms of its type. Though Kau conceptualized this prosthesis at least as far back as 2010, it’s news to me.
This is so cool! I definitely need to make one of these in 1:6 scale so that someone in Zombieville can use one!
