    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.

  abstract = {
    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.
