I wanted to show how the infareds see the mirror mounted on the dome ring .
I know the video is not that great and my hands shake, But you can get the general idea.
When the Vex is first turned on the motor finds the front position.
As the Ultra is blocked, The motor will turn to that side. If the signal is lost it returns to the front position. If the signal is constant, The motor will pause for 2 seconds then return to the front position.
