The MK2 robotic hand is printed as a single piece, including the hinges. This means that the build doesn’t require any assembly. The tendons were strung using microfiber connected to servo motors to make movement possible. The video below is from the earlier MK1 hand, but should give you a pretty good idea how well it works.
You can purchase the MK2 hand for yourself on Anthromod’s shop on Shapeways for about $200 per hand or around $375 for a pair, and you can still get the earlier MK1 hand for as little as $133 each. Anthromod plans on adding more kits, as well as building a forearm system. That could only mean that a complete 3D printed robot isn’t far behind, and Skynet will be able to generate an army just by clicking “Print…”
You can check out further progress on the Anthromod development blog.
