	*		*Drum:
			**We mocked up a drum using four traction wheels with a chase of lexan around to hold in the balls.
			**It worked well when hand cranked.
			**The drum would be used to index the balls as they come in and only trun one pie wedge as each ball came in.  If we only had two balls we would need to override the indexing and send the balls to the shooter quickly.
			**On further testing at faster speeds the balls got stuck and jammed.
			*Brushed Conveyor:
			**We had only a smal quantity of brushes to use and we were able to demonstrate that they did move the balls well.
			**We were able to confirm that the rapidly spinning brushes did not hard the game piece.
			**We may consider further prototyping to test brushes on both sides or brushes one side only, etc.
			**It appeared that this option was going to work best in a straight line.  Quick calcs indicated that would mean a +/-46" length overall so we owuld need to go diagonally through the robot.

	*~~Test with a vertical exit (and entrance)~~  or ~~a 90 degree transition~~		*TIl further testing with Helix fails, we may need to look at different materials for the Drum or further testing of the brushed conveyor.
	*		*Find brushes and a way of mounting brushes as a vertical agitator.  CAD!
			*Start CAD design
			*Do calculations to determine appropriate motor and speeds possible.
			*Figure out interface with Intake and Shooter.
			*Mock up these interfaces adn test with prototype.
			*Start thinking about what sensors might be needed and ho it will be controlled.
