URGENT(ish): Twitchy motors

[Liu_yiang]

Our robot didn't have a problem with twitching as much as it did with a constant speed, even though our readouts read zero. Our fix, strangely enough, was to copy and paste each individual part into a new program, with the exact same name. This also got rid of a nasty delay within our program.

While this is thread necro, we are getting a twitch problem whenever our robot is enabled. For some reason, we are not getting this twitch on the robotic arm. The robot motor will still twitch even when we have the motor in action. while there is no joystick input, we also get the twitch problem. Note that we have a working deadzone on the joysticks.

Are you using Jaguars or Victors? Did you tell the software which one? What kind of drivebase do you have (how many motors, how many wheels, how is the motor power transmitted to the wheels, etc.)?

We are using jaguars, but we did manage to fix it. There was a conflict between Tank drive and our motors. The tank drive class and the jaguar class were both sending signals (0) that are not synced up, therefore creating a signal slightly off zero, causing our motors to twitch. Thanks anyways

If the motor is controlled by a joystick input, then it may help to make sure that the joystick zeroes properly. This program helps in testing joystick axes and buttons:
