A toy doll with articulated moveable wrist/hand structure. A motor in the doll operates to pull on a cable which is drivingly linked to the wrist/hand structure through rotors and links that cooperate, along with regions in the wrist/hand structure to effect complex/compound rotational, translational, and revolutional motions in the wrist/hand structure. The rotors, links and regions mentioned form a pair of interactive pantograph-like arrangements that enhance the produced motions by introducing mechanical advantage.
