Our Team tested using an UltraSonic Device.. the Devantech one that now has an example.
It worked iffy at best during our testing, but we eventually found a decent place for it above where the ball was going to be pointed at an angle.
I would think optics would be a poor choice of sensor considering the nature of the orbit balls (Not a solid face) since the beam could go through on of the many gaps on it.
Or a mechanical Microswitch / Tactile Switch to have the ball run over it.
