Re: Mecanum steering
We controlled our mecanums in 2011 and 2012 with a single joystick. It has to have the extra degree of freedom (twist) in addition to the normal x/y capability. I think it was the Attack 3D joy stick.
We also used a gyro in 2011. To deal with gyro drift, we had a gyro reset button and a gyro disable button. To reset, you spun the bot until it faces what ought to be 0 degrees, and the press the button. I think we had to reset once or twice per match...
Not sure why we didn't have a gyro in 2012, but depending upon driver, it was often disable in 2011 base on driver preference.
