Will it wrinkle up when the robots are manouvering?  Seems like a cloth floor
that could slip and wrinkle under the wheels of the robots could play havoc
with dead-reckoning and similar schemes that attempt to use shaft encoder counts
to track the position of the robot.  I think we might be better off to go with
the floor we're given, and use different (black? reflective?) tape for the
line-followers if needed.

my two cents,
