ABSTRACT:
A fluid servomechanism has a first actuator driven by fluid, a second actuator, and a pressure generator for generating pressure corresponding to the difference in displacement between output shafts of the first and the second actuators. Therefore, a compact-size finger facilitating angularly free movement and having a highly elaborate human-like function can be attained.
