How do you make gravity feed work without balls getting stuck in the feeder?

piston.

Many teams in past years use rollers to positively grab balls to "roll" them into mechanism.
Using this concept a team can use rollers to roll a ball into a shooter

I guess you can say we have two "shooters" in our robot. We plan on using the inertia of the ball when it exits the conveyor to propel it into the shooter. These balls fly out of our robot no matter where we want to put them, floor goals or high goal.

In that case, would you consider the conveyor part of the shooting mechanism?

And by the same token, would a piston that pushes the balls be a part?

We just use a gravity feed. Since our balls are stored in a trough (similar to a gumball machine), not a hopper, they can roll right in to the shooter. They are prevented from rolling in by a pneumatic.
