In 2002 we had 6 wheels. Four of them (2 of them omni) were part of the main drive (tank steering). We could attach onto a goal with our "claw" (up to two goals)... if we attached to just one, we could greatly increase our strength by shooting down two wheels that caused the robot to push down on the goal, which caused the robot to lift up about 4".

The claw to grab the goals (heh... wonder if any teams this year came up with a similar design to grab the 10ft bar): http://www.team639.org/pics/2002_goal_grabber_2.jpg

Two wheels extended downwards and resulting in great strength: http://www.team639.org/pics/CANAD~12.JPG

More pics @ Team639.org , including movies of the wheels coming down.
