FRC 2468 had a curved path shooter with a custom made flywheel. We were put in the category of full court shooter most of the year but we could shoot from anywhere on the court with our lead screw lift system and custom made string potentiometer for reading deck angle of the shooter.
We also fall in the category of passive hanger that required an accurate center of gravity on the robot for the hanging.

Our hopper mechanism of delivery for the frisbees did not jam all year long in any of the matches. It is very simple but effective in delivery of the disks to the shooter wheel.
