Abstract:     A personal transporter that provides both for propulsion by a user, and, at the same time, for dynamic stabilization by means of a powered actuator. A pitch variable such as pitch or time rate of change of pitch is sensed and used to determine the torque provided to a wheel, whether in a co-rotating or counter-rotating direction, in order to maintain stability of the transporter with respect to tipping in the fore-aft plane.

First Claim:
Show all claims		 What is claimed is:
    1. A personal transporter propelled by a user, the personal transporter comprising: a. a platform for supporting the user; b. a ground-contacting module having a first ground-contacting element movable about an axis for propelling the platform with respect to an underlying surface; c. a power train for coupling power from the user to the ground-contacting element for impelling the ground-contacting element about its axis; d. a first sensor for sensing a value of a pitch variable of the personal transporter; e. a powered actuator for providing torque to the ground-contacting element in addition to any torque provided by the user; and f. a controller for governing the powered actuator based at least on the value of the pitch variable in such a manner as to maintain stable operation of the personal transporter in an operating position that would be unstable with respect to tipping in the fore-aft plane but for provision of torque to the ground-contacting element.
