I realize people have been talking about multiple cans, but Joel's message
http://www.lugnet.com/robotics/?n=3968 actually specified just one can, using
the words "find a [...] can", "pick up the can", and "[...] of the coke can".
As for making sure the whole area is covered, that's pretty tough. You need a
far more accurate type of position sensing, such as triangulation off multiple
fixed reference points. To do that with beacons that are pre-placed in the room
would probably violate the conditions of the challenge.
