A five-fingered prosthetic hand that has multiple grip patterns with the use of only one actuator.

This prosthetic hand is capable of performing one neutral position and two grip patterns that are dominant in daily life tasks. Different move patterns are achieved through the use of multiple sets of rigid four-bar linkages which provide different motions to fingers and thumb when the mechanism is actuated in the opposite direction.
