Our Project: myFive Prosthetic
The myFive Prosthetic Hand is a 3D printed, myoelectric, robotic prosthetic hand. It is designed to provide a solution for amputees with a below-the-elbow amputation. Currently available prosthetics of this type are hard to get and very expensive (around $40,000), which makes them impractical for most. The overall cost to build ours is about $250.
Our prosthetic is designed to be parametric and 3D printed, allowing it to be accessible to a greater number of people who need it, and light enough to be comfortably worn all day. The prosthetic allows for several degrees of freedom including opening, closing, and abduction of the fingers,
The myFive is controlled with surface EMG sensors placed on the residual limb. Data processing is handled onboard and motion is performed with geared micromotors. All the electronics are cheap and accessible components. An accompanying graphic user interface (GUI) allows the user to train for use of the prosthetic and better understand the way the algorithm works.

This project is a part of the Technion Faculty of Mechanical Engineering BioRobotics and BioMechanics Lab. It is a student founded and student run project whose goal is to make this technology accessible to those who need it.
As an open source project, we provide through this site all files necessary to replicate and/or modify our work. We welcome any other developers and makers to use or improve the prosthetic as long as the terms of our creative commons license are not violated. This project is NOT for profit.
