I love these long-form build logs.

I just started reading, and I am making the faux-pas of commenting before finishing.

But, I'm wondering what the challenges are of automating the ROV to map a body of water's floor in a pattern. like a grid pattern, or whatever is most efficient.

At first I was thinking currents would cause displacement. but can't we sense the current moving us in undesirable ways and correct with thrusters?

And then I thought.. do lakes have currents? Do they have tides? can a ROV sense the boundary of a lake?

just further down the rabbit hole, realizing how little I've learned about the natural environment!

Would be great to be able to read all of these as a single article! (I'm intrigued, but I'm not saving 13 blog posts to my read-it-later app. Even stitched together, it wouldn't be the longest in my list by a long shot.)

I agree and sometimes email authors to ask if they would compile (or should I say link?) a multipart article into a single piece before we put it into the second-chance pool. But even I was afraid of how long this one would turn out to be.

Thanks for giving it a second chance. I read all of it, and it was very interesting indeed
