Abstract—This paper presents a transmission mechanism
design for anthropomorphic prosthetic hand which enables it to
do both power and precision grip. The fingers and thumb is pull
type with 1 DOF and they must be adaptive towards object's
contour. In the other hand, transmission system must be small
enough to be placed in metacarpal. To solve any physical and
technical contradiction problem, we used TRIZ methodology.
The result is 3 independent motor actuation transmission
systems, each for thumb, pointing finger, and the unity of
middle-ring-little finger. Every independent system using
bolt-nut as reducer and tension spring as adaptive component.
This configuration enables the hand to do 5 of 6 basic models of
human grasping.
Index Terms—Transmission, anthropomorphic, prosthetic
hand.
