It is harder to push a mecanum robot sideways when said robot is trying to resist the push by attempting to push back than it would be if said robot simply had its wheels (wheels, not rollers) physically locked.

Have I correctly inferred your implication, or have I misunderstood?

Sort of. I understand that really the only force resisting is still static friction of the carpet and the wheels. Our force we apply with the motors I feel cancels out the slip of the rollers, leaving still static friction with the carpet. Which makes us just as good as tank if they have the same CoF.

Again the benefit of that is when a robot breaks contact with us to try to ram we continue to push against them and we back up as they do, not allowing the ram and gaining ground.

You are the numbers expert here Ether, feel free to give some numbers!
