ABSTRACT:
There is provided, in a preferred embodiment, a vehicle for transporting a payload (which may but need not include a human subject) over ground having a surface that may be irregular. This embodiment has a support for supporting the payload. A ground-contacting module, movably attached to the support, serves to suspend the payload in the support over the surface. The orientation of the ground-contacting module defines fore-aft and lateral planes intersecting one another at a vertical. The support and the ground-contacting module are components of an assembly. A motorized drive, mounted to the assembly and coupled to the ground-contacting module, causes locomotion of the assembly and the payload over the surface. A CG modifying arrangement is provided for actively modifying the location of the center of gravity of the assembly. Finally, the embodiment has a CG control loop, in which the CG modifying arrangement is included, for dynamically enhancing stability of the vehicle by operation of the CG modifying means based on at least one of motion or orientation of the vehicle.
