Sorry, that's part of my kinematic model for mecanum. The slipping happens when rotating. It actually wouldn't effect the straight movement. Sorry about that. Someday I'll actually finish writing it up and upload it so people will know what I'm talking about.

Yes, I mean force. I believe half the force coming out of the motors translated through mecanum wheels is lost. However I was trying to avoid saying that because Ether is probably going to jump all over me. I won't get into the details here. I'm going to try to create an experiment that will help clarify what is happening and will continue to discuss it with Ether in private. It is possible Ether is right, but I will need more convincing than can be done without a practical trial.
