pic: Is this corner considered protected?

[Cory]

Refer back to the string test mentioned in update two.

If you wrap a string around the perimeter of the robot, every point at which the string changes direction is considered a "corner"

Every corner must be protected on both sides by a 6" long bumper segment.

In my mind the angle immediately to the left of the pool noodle you've shown is a corner, and as such the area to the left of that angle and to the right of the trailer hitch mount must be protected by a 6" long bumper segment.
