2007 - 6wd Drop center, 2 speed servo shift by AndyMark
The robot drove well, it was easy to program, and we used a turret in place of maneuverability. While the turret was nice, we missed the ease of navigation. Also it rocked on the center wheel which would cause the drivers to readjust the tube.
Leet,

I'm curious...any preference/pros/cons between the two 6wd versions? We've done 6wd with dual omnis in the corners twice before, never a dropped center.
