Since each game is different, the robot to play each game has to meet different requirements, so it's not real likely that there is such a thing as a universal drive base. If there were, it would probably not be optimized for any game.

How about coming up with half a dozen designs that are not quite finished, but can accommodate different game requirements? You can use past games for ideas for this. Of course, the real game next year will not be satisfied by any designs you come up with before then...says Mr. Murphy
