I assume you're using Stage? The trail visualization was not added
until Stage 2.0.0, which requires Player 2.0.0. So you'll have to
log the robot's position and make the plots yourself. Matlab, or a
very recent version of gnuplot, can display a background image (e.g.,
your map) with data (e.g., your robot's trajectory) plotted on top.
