If I recall, there is a calibration button on the motor controllers that allows you to set the middle and end travel of the joystick...that is, without changing your programming at all.

I heard about it at the INNOVATION FIRST meeting at the kickoff...and I'm sure it is documented somewhere in the Motor Controller specs.

I hope this helps.....getting another joystick might also help.

: We seem to have a problem with one of our joysticks. When I run default program on our robot,
: eventually one of the motors keeps getting some 'juice' even though nobody is touching the joysticks.
: I tried swapping the joysticks which made the other motor act the same way. I tried looking at what is
: happening to the input variable responsible for that joystick and found out that even though the joystick
: sits in the middle, the variable value can be as high as 130-160 decimal. I tried calibrating the y-axis
: with the wheel on the joystick, but, alas, after moving the joystick back and forth and then leaving it
: alone it would still leak some 'juice' into the motor.

: I assumed that since we ran the robot with the default code and since the recalibration of the joystick had
: no effect on the performance, the joystick was bad.
