Re: Mecanum vs. Tank Drive?

We did mecanum wheels twice in our team's existence and both times regretted it. I agree with others that if you need precise alignment in the lateral direction(or any direction really) something is wrong with the mechanism design and not the drivetrain. Even if you do use mechanum to fix that problem, the weight of your robot is not likely to be balanced efficiently and you probably won't have a good enough driver to make mecanum worth it in the first place. Literally the only team that comes to mind that used mecanum drive effectively was 4522 in 2014. There may be a few others that actually pulled it off but they are not the norm. In fact most of the time, teams with mecanum just end up driving it like a tank anyways.
