Totally agree Ed, why are we entertaining the idea of letting robots get out and carry on? For competition it should stay as the original simple rules. If your in your out. Whiteboards are another matter , if you want to let people carry on because it adds something to your show thats no problem but not for real competition. The audience dont understand it (its different to what they have always seen), it avoids needless waiting and it doesn't favour any particular robot.
