Forwards and Backwards Ball Pickup

[evanatch]

Our team spent a lot of time discussing this today, and reached the conclusion that having a double-sided pickup would cause more problems than it would solve for us. We are using a single roller arm to pick up balls (similar to Build Blitz team JVN), and the double sided intake (via flipping the arm to the other side) resulted in some weird geometry and problems storing the ball. We figured the small advantage gained by not having to turn around in some situations wasn't really worth the trade off (especially since we're a rookie team). Instead, we chose to place our pickup on the back of the robot, and the passer/shooter on the front to better facilitate passes.
