Abstract
A finger-gesticulation hand device includes a base frame representing a metacarpal part of the human hand, and at least three digits mounted on the base frame and appearing to be a thumb and at least two fingers. Each digit has at least two phalange portions respectively linked by two joints which permit a flexing movement of the phalange portions between extended and flexed positions. An actuating cord passes through each digit and is actuated by a solenoid actuator unit to pull the phalange portions of the respective digit to the flexed position. The hand device is simple in construction and capable of making hand gestures in a simple manner.
