Maximize Capture Area

[micsfox]

I need to track mobile robots in an area that is 24 x 28 ft. We have two types of robots, one is a foot tall and the other is 3 feet tall.

What is the best camera set up for maximizing floor area (the X and Z), given the fact that we only need a couple feet captured in the Y (from ~1-3 ft.)?

I have three questions for you in regard to this:

Where are the markers located on the robots?
How many robots will be in the capture volume at any given time?
How big is the room in comparison to the size of the capture volume?

Markers are located on the top of the robots.
There should be no more than 4 robots, but I'm only testing with 1 for now.
There is about 5 feet from the capture volume to each wall of the room.
