Abstract:
A device for transporting a human subject over a surface, the device comprising:a. platform defining a fore-aft plane, the platform supporting a payload including the human subject; b. a ground-contacting module, including a ground-contacting member movably coupled to the platform, the ground contacting member characterized by a region of contact with the ground, the platform and the ground-contacting module being components of an assembly having a center of gravity, the center of gravity having a position defined with respect to the ground-contacting member; c. a support for supporting the subject, the support coupled to the platform in such a manner as to permit variation of the position of the center of gravity in the fore-aft plane by a movement of the support by the subject with respect to the platform while the device traverses the surface; and d. a drive, coupled to the ground-contacting module, for delivering power to the ground-contacting module in a manner responsive to the position of the center of gravity.
