Abstract
A method for conducting the motion of a transporter under riderless conditions. The transporter has two laterally disposed primary wheels. In accordance with the method, an input is received via a user input disposed on the transporter and a control signal corresponding to the input received is generated. Then a torque is applied to the laterally disposed wheels so as propel the transporter on the basis of at least the control signal. The control signal may correspond to either a commanded torque or to a commanded transporter velocity. The torque may include coadded terms where the terms are, respectively, proportional to the control signal, to a counteracting artificial friction proportional to the common velocity of the wheels, and a term proportional to the differential rotation of the wheels to facilitate turning of the transporter.
