Throw some holes/slots in the tube to put your hands in to manually feed the balls through to get them out or just put a door on you tube to open & access the balls with.
You need to get them out without powering up your robot.
Once or twice a jam that requires powering up isn't bad, but a consistent wait or lack or your ability to get them out at the end of a match will irritate the refs & possibly incur penalties/warnings.
You don't want that now do you?
