Description
A simple inline mechanism that will offer adaptive grip for robotic and prosthetic hands.
With a single tendon pull, you can close all the fingers together, if resistance is met by any of the fingers then the balancing mechanism will react by "seesaw" to stop that finger and carry the travel to the other finger tendons.Once all fingers are gripped around the irregular object then the loads equal and further pulling will tighten the grip across all fingers.
If you offset the the linkage towards the little finger, then this will close the index finger first, then the middle finger etc, for a progressive and adaptive grip.
