In my fourth (and final) year in engineering, I have been asked to do 
the impossible.. 

Supoose A robot was have only four photocells for a vision system..
How would it be possible for it to see effectively? This is how the
cells divide the view..



     +----------+-----------+
     |          |           |
     | Cell 1   |  Cell 2   |
     |          |           |
     +----------+-----------+
     |          |           |
     | Cell 3   |  Cell 4   |
     |          |           |
     +----------+-----------+

The vision cone is 120 degrees from the left edge to the right edge
and 120 degrees from the top edge to the bottom edge. I have found that by 
sweeping through a 120 degree 'fan' in 1 or 2 degree steps (whilst taking 
readings at each step) one can construct a *crude* view of what is ahead.

Any ideas along these lines or anything totally different are most welcome.
