So, I have searched through and read alot about the different types of omni directional drive trains, and we have decided that mecanum fits our team best.
I have one question about the orientation of the wheels though. For the wheels to work correctly andmark describes that they need to form an x pattern.
Although, It does not state that the width and length between the center of the wheels needs to be a square. Some of the kids on our team think that it does need to be in a square.
Can anyone confirm that the wheels need to be aligned in a square fasion?
