Guided Control of a Transporter
First Claim
1. A transporter for transporting a load over a surface, the transporter comprising:
- a. a support platform for supporting the load, the support platform characterized by a fore-aft axis, a lateral axis, and an orientation with respect to the surface, the orientation referred to as an attitude;
b. at least one ground-contacting element coupled to the support platform in such a manner as to provide locomotion of the support platform with respect to an underlying surface;
c. a motorized drive arrangement for driving the at least one ground-contacting element in such a manner as to propel the transporter in dynamically balanced operation;
d. a controller for commanding the motorized drive arrangement based at least on the attitude of the support platform; and
e. a user input for receiving a command from a user not carried by the transporter to govern operation of the motorized drive arrangement.

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.
