Re: Upside down Frisbees; can your team get them out?
 

Our floor pickup and elevator are separated by a small and offset lip that guides rightside-up Frisbees into the robot and upside-down Frisbees out using the Frisbee's lip and no extra mechanism. That way, if we accidentally pick up an upside-down Frisbee, it comes out before getting to our hopper, and our drivers don't need to worry about ejecting it - the bend of the elevator's aluminum and Frisbee's plastic takes care of that for them.
