Prosthetic Hand

My proposal for the "Modular Prosthetic Terminal Device Challenge" features a VO prosthetic hand with opening via two strings, one on the middle finger and another on the thumb. The strings connect to the konb above the wrist. Designed for easy one-handed operation using a butterfly washer attached to an M10 bolt, this hand also connects to the ICRC wrist for enhanced security. Metal sheets are used as springs for increased grip strength, with adjustable force levels achieved by removing 1, 2, or 3 sheets. Fingers move independently for a small angle, ensuring a better grip depending on the object being held. For more details, check out the presentation image. Thank you!
