 For certain experiments in mobile robotics, it is convenient to eliminate
 positional estimation error in the interest of analyzing other parts of
 the experiment. We designed and implemented a simple, accurate scheme
 for encoding and recovering absolute position information. The encoding
 is a two-dimensional image printed on the plane of the floor, and the
 absolute position information is recovered using a downward-looking
 video camera mounted on a mobile robot.

 This document describes work done in the Dartmouth Robotics Laboratory
 in April of 1997 and August of 1999. It was previously ``published'' as
 a web page, but we thought it would make sense to document it more
 permanently.
