Abstract
An interactive, animated, and robotic doll having movable appendages, such as a head, arms, and legs. The doll includes motors, gears and other linkages to actuate the movement of these appendages. A lockout mechanism is operatively incorporated into the doll for preventing conflicting forces from occurring. The lockout mechanism may include a shuttlecock interposed two independent linkages that drive motion in a single appendage. The shuttlecock slides between two positions, each of which limits the movement of a corresponding one of the two linkages when the other of the two linkages is actuating motion in the appendage.
