You can use a horizontally-polarized fill light in one direction and a
vertically-polarized fill light in 'tother. Then the strength and the amount

You can also use differently polarized beacons, and have the 'bots sense and
identify which is which that way. I would chose this method because it's not
dependent upon signal intensity.
