Abstract:     A device and methods for supporting a payload, such as a user, at a variable height above the ground and for repositioning the payload in a dynamically stabilized mode of operation. The transporter device has two laterally disposed primary wheels and a payload support that may be used to raise or lower the payload. A torque is applied to the laterally disposed wheels so as to propel the transporter on the basis of a control signal that may include repositioning of the device.

Family: Show 306 known family members
First Claim:
Show all claims		 What is claimed is:
    1. A device for carrying a payload, which may include a user, over a surface, the device comprising: a. a payload support which supports the payload at a height above the surface, b. a ground-contacting module, mounted to the platform, including a plurality of laterally disposed ground-contacting members and defining a fore-aft plane; c. a motorized drive arrangement, coupled to the ground-contacting module; the drive arrangement, ground-contacting module and payload constituting a system; the motorized drive arrangement causing, when powered, automatically balanced operation of the system in an operating position that is unstable with respect to tipping in at least a fore-aft plane when the motorized drive arrangement is not powered; and d. an elevation mechanism for permitting variation of the height of the payload above the surface.
