Apparatus and methods are disclosed for passive stabilization of a wheeled object by employing secondary wheels rotating about secondary axes offset from a common axis of a primary set of wheels, where the secondary wheels are positioned such that tilting of the object during rolling causes one of the secondary wheels to contact the surface and counteract tilting tendencies. The offset of the secondary axes can include angular, vertical, and/or horizontal components.
The invention claimed is: 1. A passively stabilized wheeled object comprising an object body; at least one primary wheel assembly comprising two wheels, spaced apart from each other and mounted to the object body to rotate about a common axis, the primary wheel assembly being defined by a first set of coordinates x, y and z, wherein x is the direction of motion, y is vertical and z is the direction along the common axis of the primary wheel assembly and a second set of coordinates x1, y1 and z1 defined relative to the earth, such that when the object is...
