Auto-Depth
The auto-depth is activated by pressing #2 on the controller. It is also possible
to change the target depth by scrolling up or down the gain arrows immediately
after the auto-depth is activated. After 5 seconds without adjusting the target
depth using these arrows, they will return to their normal gain adjust function.
The auto-depth feature is shown on screen by brackets around the depth
reading. For example if the depth reading is (4m), the auto-depth is active. If
the depth reading is 4m, the auto-depth is not active. When the auto-depth is
active, it adjusts the pitch angle of the ROV accordingly so that when the
thrusters are in motion, the ROV will move to the desired level. The ROV will
pitch at various angles depending on how far off target it is. If the thrusters are
not active, the ROV will not automatically thrust itself to the desired level.
Auto-Heading
The auto-heading is activated by pressing #1 on the controller. As soon as this is
pressed, the ROV will set the current heading to the target heading and attempt
to hold it until the auto-heading button (#1) is pressed again. It is also possible
to change the target heading by scrolling up or down the gain arrows
immediately after the auto-heading is activated. After 5 seconds without
adjusting the target heading using these arrows, they will return to their normal
gain adjust function.
The auto-heading feature is shown on screen by brackets around the heading
reading. For example if the heading reading is (240), the auto-heading is active.
If the heading reading is 240, the auto-heading is not active. When the auto-
heading is active, it adjusts the thrust level of each thruster accordingly. If the
thrusters are not being activated by the operator, the auto-heading will
automatically activate them accordingly in order to maintain a heading. For this
reason the auto-heading should not be activated while the ROV is on land or
anywhere near people since the thrusters can turn unexpectedly and could
severely injure someone.
