A transporter that includes a platform for supporting a load and at least
one primary ground-contacting element. The transporter includes an
actuator for applying torque to the at least one primary
ground-contacting element for propelling the transporter with respect to
a surface. The transporter also includes a controller for controlling the
actuator, the controller includes an input for receiving specification by
a user of a desired direction of travel based on a position of a member
with respect to a fiducial axis, a differentiator for calculating a rate
of change of the position of the member with respect to the fiducial
axis, and a processor for generating a yaw command signal based at least
on the position of the member and the rate of change of the position of
the member which is weighted based on the level of experience of the
user.
