What's SBL, LBL, etc?? I made these images a few years back in google Sketchup to help. There is a nice wiki page written by Marco Flagg who has been building these systems a while available here: http://en.wikipedia.org/wiki/Underwater_acoustic_positioning_system but here are the main exerpts. These systems use small ceramic elements to send clicks between each…Continue

There might be a spot for this already but I wanted to write a quick note sharing my experience getting the IMU to work. When trying to get mine to work I didn't find a solution quickly so maybe this will help!
1) Put latest image on https://github.com/OpenROV/openrov-software/releases/tag/v2.5.0-Beta I believe...
2) ssh into device (rov/OpenROV)

A half dozen people have sent me this link to the robotic sea turtle designed by the Tallinn Institute of Technology. Looks interesting.
We mentioned an opportunity for public high schools a few weeks ago, and now we're really excited to announce our latest initiative - with DonorsChoose and with generous support from the Paul Allen Family Foundation - to get OpenROVs into high schools across the country.
Right now, you can…Continue

One Moveable Platform (Sailboat)
Solar Cell Energy Source
440 amp/hr DC Battery Bank
The "Behoovus Project" as I envision it at this time is to provide the use of the
sun's renewable energy to allow extended dives for the ROV at multiple sites for
survey purposes. Emmy and I intend to send DC current down the tether, which
has been generated by an onboard solar system and stored in Sailing…Continue

I was reading up on the Santiago Mini Maker Faire on the Make: Blog, flipping through Sabrina Merlo's photos and BAM! I saw it. The gripper arm that…
It's hard to comprehend the depth and vastness of the ocean. It's also hard to comprehend how deep 100m is (which is how deep the OpenROV can go).
Our pal Brian Sullivan from the Google Oceans team has made this amazing graphic using the Google…Continue
Dear OpenROV members.
When I dry test, the controlboard25 was out of order.
At the office, it was good during all days after make done.
But yesterday I took sea trial test, it wad good at on board(dry run).
And than I let it until battery discharged (that was lunch time), after i'm back and change the battery.
That time the ROV wasn't work. I could connect with BBB. But any action can't.
I check controlboard, I found just only power LED…Continue

First Day Of Building.
When I found the ROV package in my mail I quickly laid out the parts and began building
My Grandpa has a lot of experience with glue, so he assisted me in the build.
The build went smoothly.…Continue

We've been working on some finishing touches to the software for OpenROV 2.5. There are a lot of things to get figured out (and we could use some help so please let us know if you're savvy with this sort of thing an are interested in helping), but in the mean time, I thought it would be good to post an image of the software so far. There are still some aspects of the software that could use improvement, but it is good enough to start playing with if you've just built an OpenROV 2.5. This…Continue
We're going to have another dev call next week - Monday, the 25th at 2pm PST. It'd be great to see you there. You can RSVP here:

Read your book Zero to Maker and was inspired by it. i find myself in the same situation, Laid-off and looking for a new business idea. Thought I would look at the reverse of my journey by buying the ROV and creating a business around it. Has anyone done this on this board? I would love to hear about your ideas.
Now that a bunch of people are starting to complete their OpenROV builds, we can start comparing notes on how well they perform!
To start out, here's a simple way to test system lag with you're ROV (thanks to Bran Sorem who originally demonstrated a method similar to this) :
1. Boot up…Continue
