Animatronic doll

摘要

An animatronic doll having a motor, a head frame pivotally mounted to a neck carrier, a bevel gear and a pinion gear connected to a head shaft, a first gear, and a second gear. The pinion gear is engaged with a rack of the head frame. The first gear is configured to be driven by the bevel gear and is rotatable between a first position, a second position, and a third position. The first gear does not drive the second gear when the first gear is rotated between the first position and the second position. The first gear drives the second gear when the first gear is rotated between the second position and the third position. Rotation of the head shaft rotates the pinion gear and pivots the head frame. Rotation of the second gear may rotate arms of the doll. The arms may include friction clutches.
