Abstract
A method and apparatus for conveying a printing mechanism over a surface of a substrate as the printing means creates indicia on the surface of the substrate. The present invention further provides a method and apparatus for conveying an optical sensor over the surface of the substrate so as to optically scan an image of indicia present on the surface of the substrate. In the preferred embodiment the invention comprises a compact shuttle assembly including a housing that accommodates a mobility subsystem, a sensor subsystem, a printer subsystem and a communications subsystem, each in cooperative communication with a control processor subsystem. In the preferred embodiment the mobility subsystem includes an electric motor rotationally coupled to a rolling member mounted under the housing. The shuttle assembly is guided over a top surface of substrate by selectively activating the mobility subsystem as the rolling member frictionally engages the top surface of the substrate.
