The program will check to see if the turret has swiveled too far away from the center.

The mode on the switch block should be set to Motor Rotation | Compare | Degrees.
When the turret swivels to the right of center, the degree count on motor D will be positive. When the turret swivels left, the degree count will be negative. Our robot will need to individually check to see if the turret is too far in each direction, so it will first check to see whether the turret is too far to the right. Therefore, this first switch will only be ...
