That's right, a articulating prosthetic hand that uses no electricity, and cost only $150. A 5-year-old boy named Liam in South Africa had a prosthetic hand made for him by two makers/designers, Ivan Owen (a mechanical special effects artist from Bellingham, WA), and Richard Van As (a carpenter from South Africa who lost the fingers on his right had in a woodworking accident). The developed the hand through email and sending design schematics back and forth, but got together in person in November for the first time to build the custom hand for Liam, who was born without fingers on his right hand, which they were able to build and teach Liam to use in a matter of days. Van As and Owen were each donated a 3D printer by Makerbot to help them with the design of the hand for Van As, and they have since made the design open source so that anyone can take the design and build their own hands. Named the Robohand, the prosthetic operates using whatever function the person has left to power the device.
