A balancing vehicle that supports a rider on a support such as a seat in a such a manner as to allow the position of the center of gravity of the vehicle to be varied by motion of the support. Motion of the support additionally provides for control of a drive that propels the vehicle in a manner responsive to the position of the center of gravity. The vehicle is thus capable of control by leaning of a seated rider.

1. 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. 2. A device in accordance with claim 1, wherein the support includes a seat. 3. A device according to claim 1, wherein the support is coupled to the platform at a pivot oriented to allow motion of the support about an axis substantially transverse to the foreaft plane. 4. A device according to claim 1, further comprising a handle, affixed to the platform, having a grip at approximately waist height of the subject, so that the device may be operated in a manner analogous to a scooter. 5. A device according to claim 1, wherein the support includes an articulated member, biased for supporting a portion of the weight of the subject. 6. A device according to claim 1, wherein the support has a position of local stability substantially above the region of contact with the ground of the ground-contacting module. 7. A device according to claim 1, wherein the movement of the support by the subject with respect to the platform occurs both fore and aft of any line extending vertically above the region of contact with the ground. 8. A device for carrying a user, the device comprising: a) a platform: b) a user support including a seat having a position defined with respect to the platform and coupled to the platform in such a manner that the user may vary the position of the support with respect to the platform in the course of normal operation of the device while seated; c) a motorized drive that propels the platform over an underlying surface through motion of at least one ground-contacting member, the device being unstable with respect to tipping when the motorized drive is not powered: and d) a controller, coupled to the motorized drive, for governing the operation of the motorized drive at least in response to the position of the user support. 9. A device according to claim 8, wherein the position of the support with respect to the platform may be varied by leaning of the user. 10. A device according to claim 8, wherein the device is unstable with respect to tipping when the motorized drive is not powered.
