The OpenBionics just showed a new fabrication method from a hand prosthesis that can help many people. The actual prosthesis have problems like movement’s limitations, price and weight.
However, the OpenBionics new method, presented at 2015 Hackaday Prize, can solve all these problems. The model have just two motors and, with a very smart design, their hand can make 144 different positions. They also have made a 3D CAD model that can be resized and fabricated with 3D printer or laser cut.
