This is the autonomous task. Heres the path of the robot, described in words instead of code:
1. Start at the red tile closest to the flags.
2. Turn a tiny bit to the right to aim, and shoot the top flag with our preload.
3. Re-align ourselves and drive to hit the bottom flag.
4. Back up 1 tile, turn right, and back into the wall to align the robot.
5. Drive forward with the flipper turned on, and flip the cap from blue to red.
6. Back up, turn left, reverse 1 tile, turn right, back into the wall again to align ourselves.
7. Drive forward, push the cap off of the ball, turn of the flipper and flip the cap.
8. Run the motors to lift the ball up to the ball launcher. We wait a few seconds for the ball.
9. Turn to the left, wait a bit more, and shoot the top flag in the middle column of flags.
10. Turn right, back up to the starting tile, then turn left.
11. Reverse for 1 tile to be perpendicular with the platforms.
12. Turn to face the parking platforms, and reverse into the wall to align ourselves again.
13. Climb to the middle parking platform and stop.
