Customize this Documentation - My_Notes

My_Notes are easy to incorporate directly into the pages of this manual. They can be used to clarify content, add additional information, or document your custom settings, operational tactics or procedures. My_Notes are page specific and display at the bottom of the desired page under the "My_Notes" heading. No programming is required - it is as simple as saving a file with your notes.

Creating My_Notes

My_Notes can be written in HTML or plain text. HTML allows for more flexible formatting and inclusion of images or links to other web pages.

To add a My_Note, create an HTML or text file containing the note and save it in the VideoRay\My_Notes\ folder, which can be found in the computer account user's documents folder (Documents\ for Windows 7, or My Documents\ for Windows XP).

The file should be named the same as the page in which you want the note to appear, with a "my_" prefix (without the quotes). For example, if you want a My_Note to appear at the bottom of this page, the name of the file to create is: my_custom_my_notes.html. The name of the page being viewed can be found in the address bar of the browser being used to display this documentation.

Even if you are using a text file, the file name must end with the ".html" extension.

All My_Notes files are processed as HTML, so if you are using a plain text file, you will need to add "<pre>" (without the quotes) at the beginning of the file and "</pre>" (without the quotes) at the end of the file if you want to preserve the layout. The "<pre>" and "</pre>" will not show up in the display.

When using HTML, the My_Notes folder serves as the root for relative links. An images folder is included for you to store images. You may add other folders or files as desired.

Viewing My_Notes

When you reload the page, your My_Note will appear - there is nothing else to install or configure. A sample My_Note file has been included to display the My_Note below. You can use this file as a model for creating your own My_Notes.

Updating My_Notes

To update a My_Note, simply edit and re-save the My_Note file.

Removing My_Notes

My_Notes can be removed by deleting or renaming the My_Note file.

Sizing My_Notes Display (Optional)

The default vertical size for My_Notes is set to 200 pixels, which is used for the sample My_Note below. Due to browser limitations, My-Notes do not size dynamically. This means that a long My_Note may display a scroll bar in order to view the whole My-Note. You can adjust the size to eliminate the need for the scroll bar. To set the size of a My_Note, you need to edit the file named "my_notes_size_table.js" in the My_Notes\ folder (location defined above). The file contains one line for each page of this document using the following format:

    window.page_name = size_in_pixels;

Find the line for the page that includes the My_Note you want to resize and replace the value of size_in_pixels with the desired size in pixels. The page names are listed alphabetically. Example line from the "my_notes_size_table.js" file for this page:

    window.custom_my_notes = 200;

Note that ".html" in not included in the page name, and the line must end with a ";" Also, the optimum size required is dependent upon the size and aspect ratio of the browser window.

Safety First

Operating electrical devices in and near the water can be dangerous. There is always a risk of drowning or electrocution in such an environment. Reduce these risks by using common sense and observing safety regulations and recommended safe practices including the following:

• Never handle power cords while in contact with water or allow power cord connectors or the control panel to enter the water. The only components that can safely be placed in water are the submersible, any onboard accessories and tether, and only after making sure the connections are secure.

• Always test the safety components, such as GFCI switches and interlock devices, before beginning operations. Follow the procedures described in this manual for.

• Have proper safety equipment, such as PFDs (Personal Flotation Devices), on hand and make sure you know how to use them before you need them.

• Keep fingers, hair, loose clothing and other objects away from VideoRay's propellers and other pinch points.

• Monitor weather and sea conditions and heed any warnings or alerts.

• Be aware of and follow any legal ordinances or regulations in your area regarding operation of vessels and underwater equipment in the water.

Before setting up for or commencing any dive, it is a good practice to make sure there are no hazards to people or the equipment on land or in the water. If there are other people in the water nearby, you should advise them that you are going to be operating the ROV. As the owner/operator, it is your responsibility to ensure the safety of those around you as well as that of the equipment and nearby property.

How Safe Is Safe Enough?

Addressing all aspects of safety while working in a water environment is beyond the scope of this documentation. VideoRay encourages you to participate in safety training appropriate for your industry and applications, including such topics as vessel operations, first aid, survival and other relevant topics.

Introduction to the System Components

Unpack the system and familiarize yourself with the components.

	ROV System The base system for a CoPilot RI configuration includes the VideoRay Pro 4. For more information about the VideoRay Pro 4, see the VideoRay Pro 4 Operator's Manual.
	BlueView Imaging Sonar Forward looking imaging sonar provides extended visual range capabilities. Possible targets of interest can be observed and marked, and the system can navigate to them manually or automatically.
	Teledyne RDI DVL (Doppler Velocity Logger) The DVL is used to keep track of the vehicle's location while it is underwater. It uses an array of acoustic beams to track its course over the seafloor in a local coordinate system.
	ROV GPS Antenna The ROV GPS Antenna provides a method to identify the vehicle's location within a global reference frame. GPS is not effective underwater, so the GPS Antenna only works when the ROV is on the surface. Periodic GPS fixes can supplement the DVL tracking.

Some items shown are optional and not included with all models.

Additional Items

Additional items may be supplied with your system including tools, spare parts and other items. If included, these items are described in other sections of this documentation.

Some items shown may be optional and not included with your configuration.

Pre-Dive Preparations

Select a safe and preferably level area to set up the control panel. See the On-site Operations section of the Project Management Guide for more information about site selection and set up.

The pre-dive preparations consist of three parts, a visual inspection before setting up the system, setting up the system including making connections, and power on tests of the system's safety circuits and primary functions.

Conduct a Visual Inspection

Assuming this is your first time using the VideoRay, everything should be in proper working order and ready to go, but it is good practice to perform a pre-dive inspection before every dive, even your first. If any problems are noticed, refer to the Diagnostics and Repair section of the Maintenance Guide and take appropriate corrective action, or contact VideoRay for assistance before commencing the dive.

1. Inspect the ROV and other system components to make sure there are no visible signs of damage or loose or warn parts. Also check for water inside the ROV hull by holding it with the front facing downward and look for signs of water in the main dome or light domes.

2. Check the horizontal thrusters to make sure that the shafts are not bent and the propellers are free to spin and are not fouled, loose or binding on the thruster guards. Check the thruster cartridge seals - they are filled with oil and there should be no signs of leaking or contamination. A small air bubble in a thruster cartridge seal is acceptable. See the Maintenance Guide for warnings, replacement criteria, examples and replacement procedures.

3. Check the vertical thruster to make sure the shaft is not bent and the propeller is not fouled or loose or binding on the float block. Also, check the thruster cartridge seal following the same guidelines used to check the horizontal thruster cartridge seals. Make sure the accessory port at the rear of the ROV is sealed with either a connector from an attached accessory or an accessory port terminator plug. Removal of the float block by loosening the retaining screw may facilitate this process.

Make the Connections

Connecting or disconnecting cables while the system is powered on is not recommended.

Most of the cables have been connected at the factory. See the appropriate sections of the Equipment Guide for detailed information about each of the connections.

You will typically need to connect only the hand controller, tether and power cord.

1. ROV Accessories Connections - ROV accessories are connected to the ROV using the ROV Accessory Port, The connectors are "stackable" The preferred order of connection is the sonar first, then the DVL and then the ROV GPS antenna to the ROV's accessory port. Make sure the connections are sealed using a terminator dummy plug installed in the last connector.

2. Connect the hand controller to one of the USB ports on the back of the control panel or directly to one of the USB ports on the computer.

3. Connect the female end of the tether connector to the ROV. The connectors have one pin that is offset towards the center of the connector. Make sure the connectors are clean, align the pins, and push the connectors together - do not twist the connectors. Secure the locking collar by screwing the halves together, and connect the strain relief cable from the ROV to the braided strap on the tether.

4. Connect the male end of the tether to the control panel. When not in use, keep the tether connectors clean and protected for the best performance and reliability.

5. Plug the control panel power cord into a conventional power source (100-240 Volts AC, 50,60 Hz). Power can be supplied through a land-based power outlet, generator or battery and inverter. See the Control Panel section of the Equipment Guide for power source requirements.

Power On Tests

If the system does not pass any of the following tests, it should not be used until the problem is identified and corrected. See the Diagnostics and Repair section of the Maintenance Guide for more information.

The VideoRay Pro 4 includes circuit safety component.

• The GFCI (Ground Fault Circuit Interrupter) / Circuit Breaker

Testing the Circuit Safety Components

Test the GFCI / Circuit Breaker switch (The system must be connected to a working power source to perform this test.)

1. Set the GFCI / Circuit Breaker switch to the On position.

2. Press the test switch on the GFCI. The GFCI / Circuit Breaker switch should turn off.

3. Set the GFCI / Circuit Breaker switch to the On position.

Set the Power switch to the On position. The green Power On indicator light should turn on. If the green Power On indicator light is not on, make sure the system is connected to a working power source and the GFCI / Circuit Breaker switch is turned on.

Starting VideoRay Cockpit Control Software

Make sure the system is connected to a working power source and the GFCI / Circuit Breaker and Power switches are turned on.

1. Turn on the computer and wait for the system to complete the boot up process.

2. After the computer has started, start VideoRay Cockpit using the desktop icon, or by selecting it from the Start->All Programs->VideoRay menu.

3. When VideoRay Cockpit starts, you will see the Video Window , the Control Instruments and the Control Bar . For now, you will only need to focus on the video window. See the VideoRay Cockpit Guide for details about using VideoRay Cockpit.

VideoRay Cockpit screen with simulated video image - your image will likely be different.

Testing the System's Functions

The next step is to ensure that the essential features of the ROV are functioning properly. Use the hand controller to perform the following tests. See the Hand Controller section of the Equipment Guide for more information about using the hand controller.

Joystick Depth Control knob Lights Bright button Lights Dim button Camera Tilt Up button Camera Tilt Down button Camera Focus In button Camera Focus Out button

Test the thrusters

For the next two steps, do not operate horizontal thrusters out of water for more than 30 seconds to avoid overheating or premature wear of the cartridge seals.

1. Gently move the joystick forward and backward and left and right - the horizontal thruster motors should turn the propellers. Release the joystick - it will return to center on its own, and the propellers will stop turning.

2. Rotate the Depth Control knob - the vertical thruster motor should turn the propeller. Return the Depth Control knob to center to cease the vertical propeller rotation.

Test the lights

For the next two steps, do not leave the lights on bright for more than 30 seconds while the ROV is out of water to avoid overheating.

1. Press and hold the Lights Bright button to increase the intensity of the lights - the lights should get brighter.

2. Press and hold the Lights Dim button to dim the lights - the lights should dim.

Test the camera functions

1. Press and hold the Camera Tilt Up button - the camera should tilt up smoothly through its entire range.

2. Press and hold the Camera Tilt Down button - the camera should tilt down smoothly through its entire range.

3. Press and hold the Camera Focus In button - the camera should focus in smoothly through its entire range.

4. Press and hold the Camera Focus Out button - the camera should focus out smoothly through its entire range.

If a manipulator or other accessories are attached, these items should be checked at this time.

Good Advice

The time to catch small problems before they become big problems is during the pre-dive inspection.

Dive Operations

After all of the pre-dive checks and tests have been completed successfully, you are almost ready to commence the dive. But, there is one more issue to address that could affect the performance of the ROV. The ROV is designed to be operated in a near neutrally buoyant configuration, so the last step before launching your VideoRay is to check the buoyancy. For most operations, the buoyancy is optimal when the top of the float block is even with the water surface and the ROV is level. If the ROV is to buoyant or heavy, the vertical position may be hard to maintain or control.

Buoyancy Check and Adjustment

To determine if the buoyancy is correct, lower the ROV and at least 3 meters (10 feet) of tether into the water. You can lower the ROV by the tether - it will not hurt the tether because there is Kevlar in it. Observe the ROV in the water - it should not be floating too high or sink. It should also be floating level and not tipped to one side or pitched up or down. If the ROV floats too high, you will need to add some ballast weights. If the ROV sinks, you will need to remove some ballast weights. If the ROV is not floating level, you can change the locations of the weights.

The buoyancy can be adjusted by opening the skid pods and adding or removing the supplied ballast weights. To open the skid pods, turn the ROV upside down. Unhook the retaining o-ring on the end of the pod, and lift up on the pod. The weights can be added to or removed from the slots by hand. For most operations, the weights should be evenly distributed.

Buoyancy will need to be adjusted for use in fresh water versus salt water and depending upon whether accessories are used with the ROV.

Commence the Dive

Once the buoyancy has been adjusted the ROV is ready to launch. Lower it into the water and operate the controls to maneuver it.

• Start with the ROV on the surface and push the joystick forward slightly to make the ROV move forward. Move the joystick to the left or right to make it turn left or right. Get a feel for how agile the ROV is.

• Observe the video display as well as the ROV to become acquainted with the camera's wide angle lens and its affect on depth perception underwater.

• Once you feel comfortable with the horizontal maneuverability of the ROV, rotate the depth control knob to dive the ROV. Tilt the camera down as you dive so you can see towards the bottom. Rotate the depth control knob to bring the ROV back to the surface. Tilt the camera up as you surface so you can see towards the surface.

• Change the lights settings, and adjust the camera focus. If you have a manipulator, tilt the camera down so you can see it and open and close the jaws.

• As you get familiar with maneuvering the ROV, you can start to observe some of the on-screen displays including the depth, heading, camera settings and other data.

For your first dives, practice until you are comfortable operating the controls without looking at them and you are able to control the ROV with some precision.

See the Hand Controller section of the Equipment Guide for complete information about using the hand controller and see the Piloting section of the Operations Guide for more advanced tips on piloting the Pro 4.

Practice Makes Perfect

Developing the skills to operate your CoPilot RI like an expert may take some time. Practicing on a regular basis is highly recommended.

Post-Dive Operations

At the conclusion of your dive, retrieve the VideoRay and power down the system by closing VideoRay Cockpit, shutting down the computer and turning off the Power switch. Make sure the ROV is secure before disconnecting the tether. After disconnecting the tether, keep the tether connectors clean and do not let them drag on the ground.

Proper maintenance of your VideoRay system ensures a long service life and that it will be ready to operate when you are. After each dive, you should visually inspect the system for damage that might have occurred during your operation.

VideoRay Cockpit includes an online interactive Post Dive checklist. See the Post Dive Checklist section of the VideoRay Cockpit Guide

Keeping the ROV clean is one of the most important aspects of good preventative maintenance practices, especially after using it in salt water. If you use your ROV in salt water, or water with contaminants, you should first rinse it, and then soak it in clean fresh water for at least one-half hour. After cleaning the ROV and tether, they should be allowed to air dry before being put away for storage.

Failure to properly maintain the ROV by thoroughly cleaning it after use may dramatically reduce its service life.

Glossary / Index

FAQ (Frequently Asked Questions)

1. Are there any operational limits of a CoPilot RI system?

   Other than the general limits of a VideoRay Pro 4, the DVL operating range for bottom tracking is from 1 m (3 ft) to 80 m (260 ft). Outside of this range the DVL may not be able to track the seafloor and VideoRay CoPilot's auto piloting features will not be available. Also, the DVL is an acoustic system that relies on echoes off of the seafloor. Some conditions such as heavy biological growth or being relatively close to a vertical wall may interfere with DVL tracking.

More Questions?

Additional questions and answers are available online at www.rovfaq.com, which is also linked at the bottom of each page. The online FAQ is updated regularly.

Specifications

CoPilot RI features and specifications are subject to change without notice.

Product News

See www.videoray.com for the most up-to-date product information.

ROV System

The base system for a CoPilot RI configuration includes the VideoRay Pro 4. For more information about the VideoRay Pro 4, see the VideoRay Pro 4 Operator's Manual.

Sonar

Forward looking imaging sonar provides extended visual range capabilities. Possible targets of interest can be observed and marked, and the system can navigate to them manually or automatically.

DVL

The DVL is used to keep track of the vehicle's location while it is underwater. It uses an array of acoustic beams to track its course over the seafloor in a local coordinate system.

GPS

The ROV GPS Antenna provides a method to identify the vehicle's location within a global reference frame. GPS is not effective underwater, so the GPS Antenna only works when the ROV is on the surface. Periodic GPS fixes can supplement the DVL tracking.

Navigation Chart Display

The navigation chart display is the main panel in the pilot interface. It allows the user to monitor the position of the ROV in real-time. It is also possible to use the navigation chart display to generate pilot commands for the ROV by selecting coordinate locations with a mouse when in an Auto Fly mode. For example, when in AUTO FLY Click and Go mode, a left-button mouse click in this display generates a new position request for the ROV, and a right-button mouse click generates a new heading request. The background of the Navigation Chart Display can be either a grid or a chart. A sonar image overlay can also be displayed for target recognition and location determination.

The navigation chart displays a plan view of the ROV and the surrounding area. The ROV position is calculated by VideoRay RI CoPilot's navigation system - the accuracy of which depends on the frequency and quality of the absolute navigation fixes. The display is always centered on the ROV, so it will appear as if the grid or chart is moving under the ROV.

By default, magnetic north is up on the screen. The ROV will rotate in the center of the screen to reflect the current ROV heading. Other viewing modes are available, see the view orientation section of the Operations Support Tools for more information.

The ROV is represented by a blue rectangle with a line projecting in the direction the ROV heading. Other general interface elements include:

• Red Dots - A breadcrumb trail of red dots indicating the path that the ROV has taken can be displayed.
• Range and Bearing - The range and bearing from the ROV to the position indicated by the mouse can be displayed.
• Turns count - The number of turns the ROV makes over its own axis is displayed on the left side of the navigation chart display. A clockwise turn is represented by a positive value, and an counter-clockwise turn is represented by a negative value.

The navigation chart display is also responsible for displaying heads-up messages and auto flight indicators. The auto flight indicators can help the operator understand what the system is doing.

• "DP Standby" message - The system does not have sufficient sensor data for tracking and cannot initiate an auto flight mode.
• "Offline" message - The offline planning mode is active. The Offline planning mode allows surveys to be created and simulated.
• Red Cross - The Objective Location, which indicates the location to which CoPilot will attempt to navigate the ROV while in an auto flight mode.
• Yellow Line - The Objective Heading, which indicates the heading to which CoPilot will attempt to turn the ROV while in an auto flight mode.
• Red Line - Connects the location of the ROV (at the moment when auto flight is initiated) with the Objective Location defined by the operator.
• Green Line - Connects the current location of the ROV with the Objective Location when auto flight is in progress. This line updates continuously until the Objective Location is reached.
• In Position Tolerance Indicator (Nudge Box) - A gray box displayed around the ROV. If the Objective Location is within this box, the ROV is considered In Position. This box is only displayed when the mouse is hovered over the blue rectangle ROV indicator.
• Blue Lines - Indicate a planned survey route.
• Survey Waypoint Numbers - Indicate the sequence in which the survey waypoints will be visited.
• Blue Dots - Markers.
• Yellow Dot - Selected marker.

Navigation Chart Display Zoom Scale Control

The navigation chart display zoom scale allows the user to change the viewable area and displayed size of objects. The scale of the viewable area is measured from the center of the view to the right or left edge of the viewable area. The scales are set to pre-defined values of 2m, up to 50,000m (or their equivalent values in feet).

Water Column Display

The water column display is positioned on the right side of the interface. It allows the user to visualize the depth and altitude above the seabed (if available) of the ROV in the water column. The ROV remains in the center of the display at all times. A left-button mouse click in this display generates a new depth/altitude request for the ROV. A right-button mouse click has no effect in this display. The water column display can be operated in either depth or altitude mode. This option allows the ROV to remain at a constant user-defined value. In depth mode, the ROV will maintain the specified depth of the ROV relative to the sea surface; in altitude mode, the ROV will maintain the specified altitude of the ROV relative to the sea bed. The depth/altitude mode can be changed by clicking on the button at the top of the water column display. For example, if the button indicates that the display is in "Depth" mode, it will change to "Altitude" when selected. While in AUTOFLY or CRUISE mode, the user can control the ROV's Z axis (Heave) by left clicking at the desired objective depth or altitude. The ROV will then ascend or descend to the specified depth or altitude, depending on the selected display mode. The sea surface is displayed in cyan and the seabed icon in yellow. The current depth/altitude is represented by an arrow the same color as the ROV and the objective depth/altitude selected by the user is represented by an arrow the same color as the target waypoint in the navigation chart. Water Column Display Zoom Scale Control The water column zoom scale allows the user to change the range of view above and below the ROV. The ROV is always at the center of the water column display; the water surface and seabed are also displayed but move according to the current depth and altitude of the ROV. The zoom scale of the viewable area is measured from the center of view to the top or bottom of the viewable area. The scales are set to pre-defined values of 2m, 5m, 10m, 20m, 50m, 100m, 200m, 500m and 1000m (or their equivalent values in feet).

Flight Status Panel

The Flight Status Panel is displayed in the upper left of the interface. It provides real time information about the position and movement of the ROV.

The flight status panel provides the user with the following ROV information:

• Lat - ROV Latitude
• Lon - ROV Longitude
• H - ROV Heading
• D - ROV Depth
• A - ROV Altitude
• N - ROV Northing (local coordinate system)
• E - ROV Easting (local coordinate system)
• Xv - ROV Horizontal Velocity (+ is forward)
• Zv - ROV Vertical Velocity (+ is diving)
• Hv - ROV Rotational Velocity (+ is clockwise)

This information is normally updated from the navigation system, but if the DP is in standby only the raw ROV information is displayed. No values are displayed if no ROV information is detected.

Flight Controls Panel

The Flight Controls Panel is used to select the flight mode and indicate which flight mode is active. It is also used to select the desired speed of the ROV while operating in an auto flight mode.

Selecting a flight mode button changes the flight mode and the active button is displayed in yellow with a cyan outline. Likewise, selecting a speed button changes the speed at which the ROV will operate when operating in an auto flight mode. The selected speed is displayed in yellow with a cyan outline.

Flight Modes include:

• Stay
• Manual Mode
• Auto Hover
• Auto Fly
• Cruise

Speeds include:

• Slow (0.0125 m/s)
• Medium (0.25 m/s)
• Fast (0.5 m/s)

When the DP is in standby, the only mode enabled is MANUAL and the rest of the buttons are disabled.

When using the joystick to override an auto mode (other than Cruise Mode, where the joystick override is not enabled), the ROV's maximum speed is still restricted by the speed selection. If you want full power, you will need to change to Manual Mode.

MANUAL Mode

In Manual Mode, the pilot is in full control of the ROV. CoPilot will not make any attempt to control the ROV's behavior.

Stay Command

The Stay Command can be used to interrupt an auto flight mode and stop the ROV. After the Stay button is pressed, the system will engage Auto Fly mode with the ROV holding station according to the user preferences setting for Enable Station Keeping.

The Stay command can be used to stop the ROV in an emergency while it is in an auto flight mode.

Velocity Controls

The velocity controls allow the user to select the desired speed of the ROV while in an auto flight mode. The speeds are defined as slow (0.125 m/s), medium (0.25 m/s) and fast (0.5 m/s).

While in an auto flight mode, the speed can be reduced at any time, but the speed cannot be increased without first reverting to manual mode.

In manual mode, the speed setting is ignored, however when using the joystick to override an auto flight mode, the maximum speed will be restricted to the selected speed setting.

AUTO HOVER Mode

In Auto Hover mode, CoPilot will attempt to maintain the ROV's current position, depth (or altitude) and heading within a set tolerance about its current position.

The user can use the joystick to override Auto Hover mode for horizontal and/or vertical control of the ROV.

If there are no joystick navigation control inputs, the "In Position" status indicator will turn green and CoPilot will attempt to control the ROV according to the setting of the Enable Station Keeping selection in User Preferences.

• With Enable Station Keeping selected, CoPilot will attempt to keep the ROV within a set tolerance centered about the current location, but NOT necessarily attempt to maintain the ROV's heading.

• With Enable Station Keeping NOT selected, CoPilot will attempt to maintain the ROV's heading, but will NOT necessarily attempt to keep the ROV within the set tolerance. CoPilot will also attempt to prevent the ROV from moving forward or backward, but NOT prevent it from drifting laterally.

To exit Auto Hover mode, select another Auto Fly Mode, Manual mode, or press the Stay command. Pressing the Stay command will cause the system to enter Auto Fly mode.

If you manually override Auto Hover by using the joystick, all aspects of Auto Hover are disabled. This means that if you pilot the ROV to a new location, the depth (or altitude) will not be maintained, and must be manually controlled as well. Conversely, if you change the ROV's depth (or altitude), the ROV may drift from its current horizontal location.

When using the joystick to override Auto Hover mode, the ROV's maximum speed is still restricted by the speed selection. If you want full power, you will need to change to Manual mode.

If the system loses DP while in Auto Hover mode, Auto Hover mode will be canceled and manual control mode will be entered.

AUTO FLY Mode

Auto Fly will attempt to navigate the ROV to a desired location or series of locations specified by the user. There are several Auto Fly modes. After selecting Auto Fly, the user selects the Auto Fly sub mode.

1. Click and Go
2. Go to Waypoint
   1. Global Waypoint
   2. Local Waypoint
   3. Relative Waypoint
3. Survey Plan

These modes are described in the following sections.

AUTO FLY - Click and Go

 

In AUTO FLY Click and Go mode, CoPilot will attempt to control the ROV's motion according to mouse inputs in the Navigation Chart area. A left-button mouse click changes the objective location for the ROV to the coordinates where the click occurred, and CoPilot will navigate the ROV to that location at the speed specified by the Velocity Controls selection. A right-button mouse click in the Navigation Chart area will cause CoPilot to change the ROV's heading to the bearing from its current position to where the click occurred.

The ROV's depth (or altitude) can be controlled by a mouse click in the Water Column display area.

When AUTO FLY Click and Go is initiated, the ROV's objective location, heading and depth (or altitude) are initially defined as its current location.

When an objective location has been defined be a left mouse click, it is represented by a red cross. A red line is displayed from the point at which Click and Go was activated to the objective location. A green trajectory line is drawn between the current ROV position and the objective location and this line is updated as the ROV approaches the objective location.

When an objective heading has been defined be a right mouse click, it is displayed by a yellow line of fixed length from the current ROV position and oriented at the requested objective heading. The objective heading is also displayed as a number at the end of the objective heading line.

Once the objective location or heading is achieved, the "In Position" status indicator will turn green and CoPilot will attempt to control the ROV according to the setting of the Enable Station Keeping selection in User Preferences.

• With Enable Station Keeping selected, CoPilot will attempt to keep the ROV within a set tolerance centered about the current location, but NOT necessarily attempt to maintain the ROV's heading.

• With Enable Station Keeping NOT selected, CoPilot will attempt to maintain the ROV's heading, but will NOT necessarily attempt to keep the ROV within the tolerance box. CoPilot will also attempt to prevent the ROV from moving forward or backward, but NOT prevent it from drifting laterally.

The user can use the joystick to override AUTO FLY Click and Go mode for horizontal control of the ROV. Depth cannot be overridden. If manual override is performed, the objective location will become to location of the ROV when the pilot releases the joystick.

To stop the ROV while under CoPilot control, press the Stay command button. Pressing the Stay command will cause the system to enter Auto Fly mode.

To exit Auto Fly Click and Go mode, select another Auto Fly mode or Manual mode.

When using the joystick to override Auto Fly mode, the ROV's maximum speed is still restricted by the speed selection. If you want full power, you will need to change to Manual mode.

If the system loses DP while in an Auto Fly mode, Auto Fly mode will be canceled and manual control mode will be entered.

AUTO FLY - Go to Waypoint

 

In AUTOFLY Go to Waypoint mode, CoPilot will attempt to control the ROV's motion according to keyed in values entered by the operator. Once the objective location is entered, CoPilot will navigate the ROV to that location at the speed specified by the Velocity Controls selection.

There are three types of Waypoints:

1. Global Position - GPS coordinates and depth (or altitude)

   

2. Local Position - Coordinates entered and depth (or altitude) in a local reference frame

   

3. Relative Position - Distances measured from the current location of the ROV

   

Once the Waypoint is achieved, the "In Position" status indicator will turn green and CoPilot will attempt to control the ROV according to the setting of the Enable Station Keeping selection in User Preferences.

• With Enable Station Keeping selected, CoPilot will attempt to keep the ROV within a set tolerance centered about the current location, but NOT necessarily attempt to maintain the ROV's heading.

• With Enable Station Keeping NOT selected, CoPilot will attempt to maintain the ROV's heading, but will NOT necessarily attempt to keep the ROV within the tolerance box. CoPilot will also attempt to prevent the ROV from moving forward or backward, but NOT prevent it from drifting laterally.

The user cannot use the joystick to override Auto Fly Go to Waypoint mode for horizontal or vertical control of the ROV.

To stop the ROV while under CoPilot control, press the Stay command button. Pressing the Stay command will cause the system to enter Auto Fly mode.

To exit Auto Fly Go to Waypoint mode, select another Auto Fly mode or Manual mode.

When using the joystick to override Auto Fly mode, the ROV's maximum speed is still restricted by the speed selection. If you want full power, you will need to change to Manual mode.

If the system loses DP while in an Auto Fly mode, Auto Fly mode will be canceled and manual control mode will be entered.

AUTO FLY - Survey Plan

 

In AUTOFLY Survey Plan mode, CoPilot will attempt to control the ROV's motion according to a series of survey waypoints entered using mouse clicks or keyed into a table. Once a survey is started, CoPilot will navigate the ROV through the series of survey waypoints at the speed specified by the Velocity Controls selection.

Survey controls include:

• Stop
• Reverse
• Play / Pause
• Skip
• Delete Survey
• Load Survey
• Save Survey
• Edit Survey

Once a survey waypoint is achieved, the "In Position" status indicator will turn green and CoPilot will attempt to control the ROV according to the setting of the Enable Station Keeping selection in User Preferences.

• With Enable Station Keeping selected, CoPilot will attempt to keep the ROV within a set tolerance centered about the current location, but NOT necessarily attempt to maintain the ROV's heading.

• With Enable Station Keeping NOT selected, CoPilot will attempt to maintain the ROV's heading, but will NOT necessarily attempt to keep the ROV within the tolerance box. CoPilot will also attempt to prevent the ROV from moving forward or backward, but NOT prevent it from drifting laterally.

The user cannot use the joystick to override Auto Fly Survey Plan mode for horizontal or vertical control of the ROV.

To stop the ROV while under CoPilot control, press the Pause or Stop button in the survey controls panel or Stay command button in the Pilot Controls Panel. Pressing the Stay command will cause the system to enter Auto Fly mode.

To exit Auto Fly Survey Plan mode, select another Auto Fly mode or Manual mode.

When using the joystick to override Auto Fly mode, the ROV's maximum speed is still restricted by the speed selection. If you want full power, you will need to change to Manual mode.

If the system loses DP while in an Auto Fly mode, Auto Fly mode will be canceled and manual control mode will be entered.

Surveys can be planned and simulated in Offline Planning mode.

CRUISE Mode

In Cruise mode, CoPilot will attempt to maintain the ROV's speed and heading. Once selected, Cruise will cause the ROV to begin navigating at the selected speed and current heading. The user can issue right clicks on the Nav Chart to specify a new heading. The user can issue left clicks in the Water Depth chart to change the ROV's objective depth (or altitude).

The user cannot use the joystick to override Auto Hover mode for horizontal and/or vertical control of the ROV.

In Position does not apply to Cruise mode.

To exit Auto Hover mode, select another Auto Fly Mode, Manual mode, or press the Stay command. Pressing the Stay command will cause the system to enter Auto Fly mode.

If the system loses DP while in Cruise mode, Cruise mode will be canceled and manual control mode will be entered.

Markers Panel

VideoRay RI CoPilot allows the user to place markers onto the navigation chart area of the pilot interface to denote positions of interest. These markers can be placed automatically at the vehicles current position, manually with a CTRL Left mouse click or at a keyed in location specified by the operator. Markers can be saved and reloaded by the operator.

VideoRay Cockpit Integration

VideoRay CoPilot operates in conjunction with VideoRay Cockpit. There are several key areas of integration, including:

• Override Mode
• Compass Declination
• Compass Calibration
• ROV GPS Filter

Override

In order for VideoRay CoPilot RI to communicate with VideoRay Cockpit, Cockpit operates in override mode. This allows CoPilot RI to send piloting commands to the ROV through Cockpit. If the system becomes unstable while in an auto flight mode, the Override can be used to break this connection and return manual control to the pilot.

Compass Declination

For best results with VideoRay CoPilot RI, the local magnetic declination must be set in VideoRay Cockpit.

The remainder of this page is an expert from the Pro 4 Operator's Manual. For more information and context, see the Pro 4 Operator's Manual.

Compass

The ROV compass system is designed to display headings relative to Magnetic North. You can enter a local compass variation to account for magnetic declination. The declination is considered positive when the Magnetic North is East of True North.

The value you enter is numerically added to the heading from the ROV. For example, if you are in an area with a declination of 15 degrees West, the ROV heading will read +15 degrees when the ROV is facing True North (assuming no variation has been entered). You should therefore enter -15 for the variation, which would result in a correct True North reading of 0 when the ROV is pointed True North.

The declination is saved from session to session. Be sure to clear it or change it at the start of each session if necessary.

Beginning with version 1.8 of VideoRay Cockpit, the behavior of the Compass Variation has been reversed. In prior versions, the variation was subtracted from the ROV heading.

You can use the Turns Indicator instrument to facilitate easier navigation with respect to a fixed reference such as a dock. See the sections on the Turns Indicator instrument and Relative Heading for more information about using the Turns Indicator settings.

Compass Calibration

For best results with VideoRay CoPilot RI, the compass calibration should be completed to optimize its performance in your location. If you have moved 1 degree of Latitude or more from your last operating location or if you are operating near a large ferrous object like a ship, you should calibrate the compass. The compass calibration can be found in VideoRay Cockpit.

The remainder of this page is an expert from the Pro 4 Operator's Manual. For more information and context, see the Pro 4 Operator's Manual.

Compass Calibration - Vector Nav

To calibrate the Vector Nav compass, follow these steps:

1. Start VideoRay Cockpit.
2. Click on the Engine Room button on the Control Bar.
3. Unlock the controls.
4. Click on the Calibrate Compass button, which has the magnet icon on it.
5. In the window that opens, select a Virtual Port (recommended Port is COM17). Set the baud rate to 115200 if it is not already.

   

6. Minimize the Engine Room
7. Start the Vector Nav Sensor Explorer from the Windows Start Menu.
8. Select a Virtual Port (recommended port is COM18). Set the baud rate to 115200 if it is not already.

   

9. Ensure Query Sensor after connecting is checked.
10. Click on "Connect."
11. Right click on Sensor A in the upper left pane, and select Tasks->Perform Hard/Soft Iron Calibration.
12. In the window that opens, click on Start Calibration.

    

13. Slowly rotate the ROV so that it passes through all orientations. The easiest way to do this is to think of the dome as a pain brush and you are painting the inside of a sphere. Start with the ROV facing straight down. Lift the ROV in an arc until it faces straight up. Rotate 15 degrees. Lower the ROV to face straight down again. Rotate 15 degrees and repeat this process of up and down arcs until you have rotated a full circle.
14. Continue until the measurements have been completed and "Write Parameters to Chip" button appears.

    

15. Click on Write Parameters to Chip button.
16. Close the Vector Nav Sensor Explorer.
17. Expand the Engine Room.
18. Select None in the Port selection of the Compass Settings Window.
19. Close the Compass Settings window.
20. Close the Engine Room.
21. Check the calibration against known source.

Support for the Vector Nav compass requires VideoRay Cockpit version 1.8.35 or higher and ROV firmware version 2.6.4 or higher.

ROV GPS Filter

For best results with VideoRay CoPilot RI, the GPS Filter should be tuned to optimize its performance in your local conditions. The GPS filter can be found in VideoRay Cockpit.

The remainder of this page is an expert from the Pro 4 Operator's Manual. For more information and context, see the Pro 4 Operator's Manual.

ROV GPS Instrument

The ROV GPS instrument provides ROV location, status and filter settings for the ROV GPS.

The GPS data is only valid when the ROV is at the surface and the GPS antenna is exposed.

Display

Use

The ROV GPS instrument will display the current location and status of the ROV GPS. It also has the ability to set filter criteria that control whether the GPS information is passed from VideoRay Cockpit to other applications.

Position

The Latitude and Longitude of the GPS fix is displayed in the top center of the instrument.

Status

• Good - Data is being received and passed. If the Toggle Filter is On, the GPS has passed all filter criteria.
• Bad - Data is being received, but the data does not pass at least one of the filter criteria (see below).
• No - No Data is being received.

The number of satellites being observed is indicated by blue indicator lights.

Filters

Filters allow for better operational performance by eliminating GPS fixes that are based on poor data and have a greater degree of uncertainty. These filters can suppress apparent jumps in the reported location due to such erroneous data. Each filter is defined by a slider that represents a cutoff threshold. The cutoff threshold is set by moving the slider left or right on a scale. The value of the cutoff threshold is displayed as a tool tip when the mouse is hovered over the slider. The value of the data being received is displayed as a bar on a scale. If the value is good, the bar is green. If the value does not meet the cutoff threshold, the bar is red.

Filter Settings

• SNR (Signal to Noise Ratio) - The strength of the actual signal relative to background noise. Higher SNRs mean that the signal is stronger, which usually implies a better result. The SNR threshold setting should be set to 30 initially. If the SNR is below the threshold, the GPS information will not be passed.
• Speed (Knots) - The maximum ground speed of the vehicle based on successive GPS readings. The speed threshold setting should be set to the maximum expected speed of the vehicle - typically 1 knot. If the Speed is above the threshold, it is assumed that the GPS information is invalid and the GPS information will not be passed.
• HDOP (Horizontal Dilution of Precision) is a measure of the impact of the geometry of the observed satellites on the quality of the fix. Lower HDOPs mean that the geometric quality is better, which usually implies a better result. The HDOP threshold setting should be set to 2 initially If the HDOP is above the threshold, the GPS information will not be passed. HDOP values are generally defined as follows:
  • 1-2 Excellent
  • 2-5 Good
  • 5-10 Moderate
  • 10+ Poor
• DGPS (Differential GPS) DGPS provides a ground referenced correction to the GPS signal to improve the accuracy. If DGPS Only is checked, GPS Information will not be passed unless the signal is recognized as DGPS quality. If DGPS is not checked, the DGPS quality of the signal checked.

Toggle Filter - Toggle filter allows the filter to be turned on or off. If the filter is On, only those signals that meet all filter criteria are passed. If the filter is Off, GPS information is always passed.

The VideoRay ROV GPS is optional and may not be included in all VideoRay Pro 4 configurations.

Software Management

Managing VideoRay CoPilot software is not as complex as it sounds. Management topics include:

• Software Installation
• Software Updates
• Folder Structure

Software Installation

Installation of VideoRay CoPilot RI is a complex process. Improper installation can result in an unstable computer. If you do have an intermediate or better understanding of installing and configuring software, contact VideoRay Technical Support for assistance.

CoPilot setup currently REQUIRES that the logged in (and thus installing) user be named VideoRay. This is standard on VideoRay provisioned production machines.

This setup also requires systems using a ROV GPS Mast and DVL to have the device PAMS programmed with the standard ID's. This may NOT be the case for some devices. In which case they will HAVE to be reprogrammed with vrDeviceConf. Please contact VideoRay Technical Support for assistance if necessary.

Software Updates

For most CoPilot RI installations, it is best to remove previous versions of VideoRay Cockpit and CoPilot RI prior to installation of an update. Once the previous versions have been removed, follow the procedures for a new software installation.

Folder Structure

All CoPilot RI data is saved to a common data folder structure.

Contents	Folder
The default folder for charts	C:\Users\VideoRay\My Documents\VideoRay\Data\CoPilot\Chart\
The default folder for marker list files	C:\Users\VideoRay\My Documents\VideoRay\Data\CoPilot\Marker\
The default folder for missions, when a mission is saved	C:\Users\VideoRay\My Documents\VideoRay\Data\CoPilot\Mission\
The default folder for navigation logs, when recording has been activated	C:\Users\VideoRay\My Documents\VideoRay\Data\CoPilot\Navigation\
The default folder for screenshots, when the screenshot button is pressed	C:\Users\VideoRay\My Documents\VideoRay\Data\CoPilot\Screenshot\
Sonar logs can be found here when the log recorder has been activated.	C:\Users\VideoRay\My Documents\VideoRay\Data\CoPilot\Sonar\

CoPilot RI runs in a virtual machine. Therefore it does not have access to all folders on the host computer. It only has access to those folders that are shared, which includes the folders listed above.
