in 2002 we went to championships and we had serious drive problems with our tank drive 4 powered wheels on two motors .. at some point we decided to go with caster wheel dead center in the back of our robot causing two of our power wheels off the ground and leaving two on the ground to move around with.. we were fast robot to beginning with .... once we ran with the caster we went wild on the field we spun around about faced and out maneuvered the other teams in such great way tho if u do remember the 2002 game was a flat field game with only goals as the only real structures on the field so we had alot of running space and made good use of it
you might think that caster would make your robot go out of control but with the lifted wheels on each side of the caster every time we made turn the wheels feel to the ground and made contact with the ground breaking the turn and keeping the robot from going all over with no control so if done right it suggest the use of caster when "battling" and out maneuvering other robots is involved (it also makes great lil hat trick when the other teams trying to pin you to wall with super easy and quick about faces ) and when speed is needed over power cuz with caster u might end up with the short end of the stick everytime u push against others
Casters are great !!! just look at my thing below lol
