Re: Controlling a Mecanum drive with two joysticks?

This might actually be easier. Tank drive, with some code such that moving both joysticks to one side or the other causes the robot to slide. I think the main problem with a "sidewinder" joystick (other than converting it to analog) would be making sure that you don't twist it at the wrong time.
Or, a single stick using the thumb wheel to rotate (left side next to the stick) or even the button and trigger.
