DIY Prosthetics | Projects | Ratchet Hand | Portfolio

  • The Ratchet Hand is a DIY prosthetic. Based on the open source RoboHand, we used that structure and reinvented our own hand. The Ratchet Hand uses the ratchet mechanism so that the wheel can offer multiple utensil holders. The hand offers an amputee to use a pencil, paintbrush, sharpie, fork/spoon, and knife. This allows one to use multiple utensils for various purposes from eating to drawing.
