Abstract
A motorized doll includes an upper body portion and a lower body portion. The upper body portion may include a torso and a pair of arms. The lower body portion may include a pelvis connected to the torso at a universal joint, a pair of legs, and a pair of feet rotatable with respect to the legs. The doll is actuated to walk by a torso motor which drives the torso to tilt and rotate about the universal joint, which causes the doll to shift from foot to foot and repeatedly rotate forwards in a realistic walking motion. The doll includes a shoulder motor for rotating the pair of arms and a pelvis motor for driving the legs between a standing position and one of a crawling position or sitting position depending on the position of the pair of arms when the doll is tipped forward.
