Patent ID: 8241085

Claim:
A motorized doll adapted to walk on a support surface, comprising: an upper body portion including a torso; a lower body portion including a pelvis, first and second legs extending from the pelvis, and first and second feet coupled to the respective legs such that the first and second feet may rotate with respect to the first and second legs along respective first and second generally vertical foot axes; a universal joint rotatably coupled to the torso along a torso axis, the universal joint also being rotatably coupled to the pelvis along a generally horizontal pivot axis which is generally perpendicular to the torso axis; a torso motor positioned in the upper body portion; and a pivot crank having first and second ends, the first end being operatively coupled to the torso motor, the second end being rotatably coupled to the pelvis along a crank axis which is generally parallel to the pivot axis; wherein the torso pivots about the torso axis and the pivot axis simultaneously when the torso motor is operative, thereby inducing the doll to walk on the support surface, and wherein when the doll is laying down on the support surface, the torso motor induces crawling movement by pivoting the torso about the torso axis and the pivot axis simultaneously.
