: Hi all!

: My name is Igor. I am from team 419.

: 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.

: Has anyone else had that problem? I really don't know what to think at this point.

The trim controls on the joystick can easily be knocked out of adjustment simply by moving the stick. The first thing I'd try is using tape to secure the trim controls.
