Hi
 I am working on an IR detector that will guide a robot into a docking station.
 A IR transmitter on the docking station transmits a beam, and 2 IR detectors on the robot detects the beam and lets the robot navigate towards the target. The working distance is a couple of meters.

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...
