Yes, this is another project for the design and development of a low cost prosthetic hand. It may not be the only or the best but it is our way to make a small contribution to the cause. I hope can be useful to those who seek to help people who need a prosthetic hand. We also hope that our project becomes known worldwide and contribute to the community. We did an aluminum design because we have not a 3D printer. We try to make a simple design (a single movement, a motor, three fingers). The electronic design and software are based in arduino.
