GOAL: Complete this list of technical assignments to have a fully functioning hydrophone by end of May 2026

Software:

• Install “AcSense” software

  • Run sensors thru terminal and pull SD card to check .csv or the .csv-like files for data
  • Review both “AcSense-Mini-4CH.pdf” and “SoftwareInstallationInstructions.docx” found in the MRG SharePoint https://gtvault.sharepoint.com/sites/ADePTLab-Adept/Shared Documents/Forms/AllItems.aspx?id=%2Fsites%2FADePTLab-Adept%2FShared Documents%2FInventory%2FSensors%2FAcbotics AcSense Mini 4CH%2FDocumentation%2FDoc&viewid=5ad312b6-cd82-4739-b5ef-463028f74bf2
    • Hopefully this is sufficient?
  • Install ROS Drivers on the BlueBoat computer to enable real time data collection in the ROS topic.
    • read over ‣
    • ‣ udp interface in case ROS doesn’t work

  

Electrical:

• Connect Ethernet cord from Ac-Sense-Mini-4CH-Eth Bottle to the jst ethernet port on the Blue Robotics Network switch board in BlueROV main electronics tube.
• Inspect waterproof connections/ensure everything is watertight.
• Determine voltage needed to supply eth bottle;
  • Is it PoE (power over ethernet) i.e. the power cables are bundled into the rj45 and can are supplied via a special PoE style network switch
  • Or do we supply a separate voltage to the power pins in a more traditional way using a buck converter in the BlueROV

Mechanical:

• Determine appropriate positioning of the hydrophone array relative to the BlueROV → specifically distance from the T200 Thrusters and main body.
  • Email Erin Fischell at [email protected] with proposed plan for advice and feedback.
• Adapt the provided mount model to connect to the BlueROV.
  • There are so many possible approaches to take and I haven’t decided which one to choose yet. It should be relatively easy/straightforward.
• Design mount for the “Bottle”
  • Need to be easy to access and remove; also, cable management
• Manufacture any mechanical components for testing (can be all 3D printing, at least to start; @Thomas Devlin can run parts off the lab Bambu printers).
• Alternatively, zip-tying the hydrophone and bottle directly onto the BlueROV would likely be just as effective with for testing

This array also measures pressure and temperature. BlueROV already measures pressure (and, by extension, depth) via the Bar30 Depth/Pressure Sensor?
