For amputees, getting prosthetics can be super expensive. And if you want a robotic hand, it's even more expensive. But a company called Open Bionics has designed an open-source robotic hand, that's cheaper and faster to make, costing about 1/10th of currently made prosthetics!

This is really good news, and since they've made this totally open-source, more people can work on the design and help improve it, maybe bring the cost down even more. And it all uses available technology, including 3D printers!

Open Bionics just won the Dyson Award, celerating engineering students who are creating new things, and inspiring others to create and invent.

Check out the video above, where they fit their robotic hand onto someone for the first time, and he gets to experience shaking hands and picking stuff up. Pretty cool stuff, for being created on an commercially available 3D printer, right?
