Robots don't quit

[Mr.Roboto3335]

When I try to upload the code it says "Robots don't quit!" I would like to know why it does that and how to fix it. Thanks!

When it tells you Robots don't quit!, it will also give you a stack trace which will show the path through the code (including line numbers) which triggered the problem. By looking through that path, you should be able to identify your bug.

One thing I notice immediately is that you call TalonInit after RobotDriveInit, so the talons are null when RobotDriveInit tries to use them. This will cause it to crash.

Thank you! moving the initiatives worked.
