Abstract: An apparatus includes a base, a drive mechanism attached to the base for causing the base to move across a support surface, a bobble head rotatably coupled to the base and rotatable about at least one axis, and a vibrating mechanism adapted to cause the bobble head to oscillate about at least one axis.

Abstract: In one embodiment there is provided a mechanical device capable of mimicking a serpentine motion. The mechanical device includes a plurality of segmented portions interconnected consecutively at pivoted junctions. A rotational motor and an eccentric weight are secured about one segmented portion and at least one pair of legs extends from a segmented portion towards a contact surface and causes the segmented portion to move in a direction defined as the rotational motor rotates the eccentric weight. The additional segmented portions following the segmented leg portion follow in a serpentine motion as these portions rock and pivot to counter-balance the undulation caused by the segmented leg portion.

Abstract: An ambulatory toy includes a body; a drive mechanism coupled to the body; a plurality of leg members coupled to the drive mechanism, each of the leg members having a distal end disposed downwardly in a first position and adapted to contact a support surface; and a self-righting member coupled to at least one of the legs. The self-righting member adapted to move the distal ends of the legs of the toy from a second position to the first downwardly disposed position. The method of self-righting using the self-righting member coupled to the leg.
