Re: pic: Jester Drive:Mecanum Wheel Drive Train

Because of the orientation of the rollers, a mecanum wheelbase is never in a position where it can be pushed without skidding. In the worst case scenerio, where the robot is pushed on a diagonal, there are still two wheels with rollers whose axes are aligned parallel to the pushing force. I can't speak for the Jesters, but if their rollers are anything like ours, they have pretty good traction and pushing resistance.

On 190, we have our controls set up with a one stick to translate the robot and a second stick to control rotation. I know that they were having trouble getting everything working at BAE, but the system worked pretty well in the shop.
