Heres my idea
First, the field is the same dimension as it has been since 2000. Across the middle of the field is the 2001 midlfield barrier and see-saw bridge. There are 4 teams in alliances of 2 (red, blue, like in 2002). Along the sides of the field are 2ft diameter donut shaped rings ("donuts"). These donuts are color coded. 10 for the red, 10 for the blue. The blue donuts start out on the red half of the field (red zone) and the red donuts start in the blue half of the field (blue zone). There are also 5 of these donuts in the alliance station fo rthe human players (that should add some challenge to being a human player

) 5ft out from the alliance station wall (alliance stations are same dimensions as 2002, but centered along the shorter sides of the field) is a 6ft tall pole to put the donuts on (like ring toss almost, robotic style). Halfway in between the bridge and each alliance station are 2 flags. The red flag is on the red side, the blue flag on the blue side.
Scoring is simple
-5 points per you color donut on a pole (which pole doesnt matter)
-10 points for each robot on your side at end of the match ( to be considered on your side some part of the robot must be TOUCHING the carpet on your side of the field. (robots on the bridge in other words, dont count as on your side unless part of them is touching the carpet on your side)
-15 points for capturing your opponents flag (capturing means that it is FULLY on your side of the field)
The match ends when the 2 minutes are up or when a flag is captured, whichever comes first
