When you say "stick", what do you mean?



Here's a stab in the dark: if you tell the robot to spin clockwise, does it break? If so, which motors "stick" and which ones lose signal? How about if you tell it to spin counterclockwise?
The motors "stick" at what seem to be random points, whether the robot is driving or standing still. We could reproduce it every test, but not by doing something. They just happened (but sometimes it did seem like moving the joystick caused it, but that was just because you can see it best in those situations).

Sorry! Stick is a term we like to use. Stick means the motor freezes at an output when it isn't supposed to. Our victors would be either showing disconnected or driving the motors when the joystick was at a neutral state.

We are using the mecanum code, and all we do is pass the joystick axis values into the x, y, and rotation. Not sure what you mean by changing the spin?
