1. A mobile toy vehicle, comprising:
- a wheel;
a weight coupled to the wheel via a shaft, including a main weight and a sidewise adjustable weight, wherein the main weight is fixed to the shaft, and the sidewise adjustable weight is coupled to the main weight and is movable sidewise relative to the main weight;
an outer body member fixedly coupled to the main weight and the sidewise adjustable weight, wherein the outer body member and the main weight are rotatable relative to the wheel so that the outer body member can swing relative to the wheel;
a first motor to drive the shaft relative to the wheel so as to generate forward/backward swing of the main weight and the sidewise adjustable weight to thereby cause locomotion the vehicle; and

Abstract
The present invention generally relates to apparatuses having some characteristic(s) of traditional “roly-poly” toys, which are traditional passive toys that, when struck, wobble about their typically-rounded base but stay upright due to bottom-heavy weighting. Some embodiments of the present invention can be especially relevant to such an apparatus that is mobile and/or not totally passive. For example, some embodiments of the present invention have locomotive ability, for example, via one or more wheels or other type of roller(s)
