How can i make a prosthetic hand?
“with string” I assume means you want to do it manually and not with electrical operation Your best bet it to look at the skeleton of the hand and perhaps buy a large plastic model. Then study the tendons and where they go and link the joints, perhaps with rubber bands, modeling the tendons with the string. You will find you need 15 or more strings to close and open each finger plus move the fingers from side to side. A glove over the plastic will act as skin.
