Dragon's Breath Cave, Namibia

I was wondering if the ROV community could advise me about whether portable ROV's exist for exploring deep lakes.  The one that I am examining specifically is located in Dragon's Breath Cave in Namibia.  This is the world's largest underground lake, 5 acres in area.  100 feet below the surface.  The depth of the lake is beyond 300 feet, and its bottom has not been surveyed. access is through a small hole in the ceiling.  you can get inflatables down there, but do small portable ROV's…

Finding Acrylic Cement Outside the USA

Finding acrylic solvent has been a difficult thing for international OpenROV users. OpenROV doesn't have the means to be able to ship this stuff from HQ due to mild flammability and different country restrictions. I'm writing this post to give ROV'ers around the world a place for information they need to find acrylic cement in other countries. I'd like to invite any comments from folks who've been successful at this so that others may learn and succeed as well.

This discussion…

When Bad Things Happen to Good Robots

I wrote a long, opinionated piece about telerobotics and everything I've learned over the past few years working with Eric on OpenROV. Here's the crux of the argument:

telerobotics is ushering in an era of connected exploration, a new model for discovery…

Pressure Testing Results!

Hey Guys, 

After an Etube end cap failed on an expedition in Lake Shasta, we decided to conduct an experiment on end cap assembly and methods which we believe might negatively affect the integrity and therefore fail at a lower PSI than expected. 

We lost many end caps and Etubes in the process, but we came out of it more knowledgeable about our…

Supporting citizen science on OpenExplorer!

Last month, we launched OpenExplorer to a wider audience and asked what you'd explore with an OpenROV. We offered a few OpenROV kits as an incentive to get the first ideas out on the site. To be perfectly honest, we weren't quite sure what to expect. Well, we were completely blown away. There were so many great ideas and inspiring expeditions posted that we felt terrible about not being able to send ROVs out to…

Protect Ya ROV

ROV headquarters is littered with Pelican cases. Rather obscenely so. It seems that even if there were something perfectly capable of traveling in relative safety and comfort without any sort of hardcase, Eric would buy a hardcase for it just to be sure. As evidence of such I present to you the following picture of the all cases within arm's reach as I wrote this post.…
