The EZnav Position Sensor from Intelligent Solutions Inc. could provide 
your robot with position information in the room you described with 
accuracies of better than an inch.

The EZnav sensor uses an eye safe scanning laser with a 360 degree field 
of view to measure the angle to wall mounted reference reflectors.  The 
angle data can be used to triangulate the position of the robot relative 
to the known target locations.  The current sensor outputs target code 
and angle data but we are presently working on including the 
triangulation calculation on board so that the sensor can directly output 
X, Y and pointing angle.

Email me an address for more information.  I am directly involved with 
the EZnav sensor as one of the designers.
