Can the robot ALWAYS see the docking station?  What happens if an
obstacle (wall?) comes between the two?

Can either device (robot/dock) ever slip out of the shared plane?

Can the docking station be moved, from day to day, site to site, etc.?

Is the arena indoors?

I have become particularly fond of using cameras to interface with
the real world.  Of course, it requires a bit more horsepower but
seems to be able to overcome all of the issues that have crept up...
