OpenΒionics is an open-source initiative and a nonprofit organization that has connected researchers from USA and Greece for the development of affordable modular prosthetic hands, that can be easily reproduced even at home by using a 3D printer, detailed instructions and inexpensive, but strong, flexible and durable plastic materials. The OpenBionics design very functional and light-weight robotic prosthetic hands, which costs between $100 and $200. Personally, I think their initiative really excellent and really appreciate what they are doing!
An overview of the OpenBionics project
The OpenBionics hands prototypes weigh less than 300 grams and have a novel differential mechanism that allows the patient to block the movement of each finger independently and helps to make more than one hundred different grasps. All information and files can be found in OpenBionics GitHub Repository.
