The 2007 rules do not specifically address a round robot base. In the robot section of the rules, Rule 37 gets very specific about bumper design. Those bumpers that meet the criteria may be weighed separately from the robot weight. Those bumpers that do not, cannot qualify for the exclusion and must be weighed with the robot. I would put this question to the Q&A as soon after kickoff as you can IF you still plan to use a round base after the game is announced. Decisions made on robot design before kickoff may not be the best fit for game play after kickoff.
