I don't anticipate having the time to participate myself either. I have some ideas on how to go about it though, which I've already posted.

The Cybermaster does not appear to be robust enough to handle this sort of challenge. I'm not the organizer of this event, so I can't say that Cybermasters aren't allowed, but if the only way to get the Cybermaster to do anything as intricate as what this
contest demands is to allow a computer to control it, then my vote would be to simply not allow the Cybermaster. Using computer control would render the challenge of trying to develop a useful program within the constraints of the RIS moot. A full blown
mapping program could be developed on a PC and the PC could do all the work, with the 'bot only responding to remote commands from the PC. If this is to be allowed, then there should be two categories of entrants, those with PC's and those without.
> I think the most difficult part for RIS going to be to return to the starting place with the can (Humm... maybe not), while in the CyberMaster the most difficult part is probably finding the can and manage to make anything useful out of the parts we have.
True I haven't figured out a solution for this myself yet either. (at least not one that doesn't require tethering the 'bot to the start , or an IR homing beacon of some sort placed in the start area so it can find it.)

The can may be either filled with soda, or empty, as desired.

Yes.
Both of these questions are directly addressed in the rules located at http://home.connect.net/joel/challenge.html
