Do you want to get out of a loop or stop autonyms? Do you want to just end or stop the entire program in general or just in driver/user control or autonyms?
You wouldn’t do that through the program then. It would be through the robot and or the controller. You’ll just hit the power button on the controller/ hold it and that should work. You can do the same thing on the cortex as well. Let me know if this helps or if you have any more questions!
