It seems like it would be fairly simple to, say, store the current gyro angle whenever you start going straight (i.e. not rotating), and have a PID controller change the "rotate" value to maintain the same angle as long as you're trying not to turn. Has anyone done anything like this?
I don't think "mecanum" even has a correct pronunciation; on our team we say me-CAN-um /məˈkę.nəm/, but I think i've heard MEC-(a)-num /ˈmɛk.(ə.)nəm/, which presumably is where the "mecnum" spelling comes from.

Absolutely. It's not terribly complicated either. After all your meCHanum motor set speeds are calculated, mix in a component from the gyro useing a PID. Only do this when the driver is using the strafe functions. Disable it when he is turning.
Easy Peasy.
Analysis is a tool. Like any other tool you need to figure out where and when to use it. That's the tricky part. - ChrisH [more]
