Possessed robot

[Alan Anderson]

Your programmer has probably written the "extend elevator" code as a loop waiting for the elevator to get to the desired location. A loop like that "stalls" the rest of the code. I'm surprised your robot isn't shutting down due to a communication watchdog timeout.

What you'll need to have instead is to start the motor and do a one-time computation of a global variable defining how long to run the motor when the button is first pressed, then a quick test in the teleop code to see if the time has elapsed and stop the motor if it has. Teleop is already called repeatedly from inside a loop.
