Re: 2015: Year of the Mecanum

Has anyone done anything with using a gyro to correct mecanum issues? People have mentioned it in this thread but I couldn't find any examples online (all I found were examples of how to use gyros for field-oriented control, which is cool too). 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.
