- 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..

- 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.
