Introduction
It it time to apply the finishing touches and power on your ROV for the first time!
-
-
Since the o-rings will make a pretty tight fit with the tubes, it is recommended that a lubricant be used on the o-ring to assure the o-ring gets seated properly.
-
We like to use a common lubricant called "MagicLube" which is available at many hardware stores.
-
To apply the lubrication to the o-ring, squeeze a small amount of lubrication onto your finger and then move the o-ring through your fingers.
-
-
-
Plug in the other side of ethernet and USB cables to your laptop and watch your ROV power on!
-
The USB connector acts as the on/off switch for the ROV.
-
The ROV has a built in static IP address of 192.168.254.1, so to connect with it, your computer's ethernet IP address should be on the same subnet, i.e. "192.168.254.2". The subnet mask should be set to 255.255.255.0.

OS X (Mac): Open System Preferences, click Network. Select "Edit Locations" from the Location drop down. Click the (+) and create a new location called "OpenROV". Select your ethernet adapter on the left and select Manually from the "Configure IPv4" drop down. Set the IP address to 192.168.254.2 and subnet mask to 255.255.255.0. Press Apply.

-
-
Open Google Chrome web-browser. If you do not have the latest version of Google Chrome, you can go here to get it.
-
Before being able to log into the ROV, it will need to have time to boot up. Wait at least 2 minute after turning the ROV on before trying to log on.
-
In the status bar at the top, type 192.168.254.1:8080, which is the IP address of the ROV. Press 'enter' and cross your fingers. Soon the OpenROV Cockpit should appear. It may take 10-20 seconds for the page to finish loading.
-
-
-
There are two lasers that we are going to mount to the ROV. These laser beams will be 10cm apart and be parallel. When turned on underwater the dots will always be 10cm apart acting as a scale for underwater measurements.
-
Create a "Laser Calibration Station" (Piece of paper with two X's that are 10cm apart in a straight line).
-
-
-
Test to see if the propellers are rotating in the correct direction. On cockpit, hit the up arrow while looking at your motors to see which direction they are spinning.
-
Port should be running counter-clockwise.
-
Starboard should be running clockwise,
-
For the Vertical Prop, when hitting the Ctrl button, it should be rotating counter-clockwise when looking from the top.
-
-
-
Bevel the inner edges of the main tube using a medium grit sandpaper so that the o-ring will fit in the tube without getting damaged by the sharpness of the tube's inner edge.
-
Wipe off all the dust left over from the sanding process when done.
-
Do not scratch the inside of the tube. This is where the o-ring seals (see steps below).
-
-
-
Amazing! You should now have a complete OpenROV version 2.8!
-
Head over to the operator's manual for further instructions on how to drive and maintain your OpenROV.
-
If you ordered upgrades for your ROV please head over to the Upgrades and Accessory instructions to get started building those!

On behalf of the OpenROV team and community at large, we are happy to have you with us. See you on the forum, OpenExplorer, and wherever your adventures take you.

I can not connect to the ROV. I DID manage to do so once. But only one. Using a Macbook Pro, I disabled the wireless, set the ethernet to 192.168.254.2 and set the mask. Plugged the cable in and the browser times out. I tried switching the ethernet cable to a crossed cabled and that gave me nothing either. I plugged the ROV into a gateway and ran a lan scan. The ROV 192.168.254.1 did not show up.
I'm stumped. Especially as it did connect the first time.

Hey David I had a similar issue, I just updated the beagle bone black and it worked again.
Hey!!! Today I did fished assemblig of my new OpenROV 2.8 everything was incredible well explained and detailed. just a minor couple of things that I figured out because at the end they were very logic. This is an incredible guide for a complex device. yet so simple to follow the guide, and at he end everything worked perfect!
Now I will do the first water test in the pool. hope everything goes well!
Thanks to all the OpenRov team. and Congratulations on this magnificent assembling guide.
Best Regards!!!

Thank you for all of the kind words! We are glad that you enjoyed the guides and the build process. We have definitely learned a lot about the best ways to create these assembly instructions and I am glad to hear that our work is paying off. I hope that your test goes well and that your ROV has many adventures ahead of it! -Brian G.
