DIT (Do-It-Together) Exploration

Over the past few years, the most fun and educational aspect of developing OpenROV has been going on the various expeditions: Hall City Cave, Sea of Cortez, Searching for the SS Tahoe, etc. The expeditions (however makeshift they were/are) have been rallying points for feature development, bug-fixing and, most importantly, meeting new friends and collaborators. On each trip, we've widened the circle of friends that have taken part in this adventure. In fact, it's exactly that aspect - a…

  • We're changing our recommendation to safer, more reliable batteries
  • The new batteries will work with all 2.5, and 2.6 ROVs but require an adapter (see below), new…

Deep Ocean ROV using a Glass Sphere Pressure Housing

Here is some updated information on a very interesting full ocean depth capable vehicle which is now being commercialized by a company in Norway.  The actual glass sphere housings cost around $1000 - $2000 depending on size and number of penetrations required, but to get one that is optically polished adds  another $5000  to the price.  To my knowledge with the recent demise of Nereus, this is one of the few operational vehicles capable of reaching these depths.…

Node.js Prep for OpenROV

OpenROV is controlled through a web browser. The server-side of the web app is written in Node.js, running on a BeagleBone Black inside the OpenROV. You don’t need to know Node.js in order to pilot an OpenROV. But if you’re the kind of maker who likes to dig deep into a project, you might enjoy exploring the language. Details: Node.js Prep for OpenROV

Any ROV builder in Switzerland or southern Germany that want to hang out?


I'm here in Switzerland with my ROV #463 and would love to meet up with fellow OpenROVers!

Any interest in hanging out somewhere between now and end of July?

If we get a space somewhere, we could do a build day or bug fix day too. I've got plenty of experience with the ROV nd the software!

Regards Dominik

Updated default listing of posts in the forums

Hey everyone,

For those that knew the trick, there is a way to sort the forums by most recent activity instead of by category.  We have been using this for months and found it way easier to navigate with.  So we have now changed the default setting for everyone to sort…
