Yeah, I have noticed a good bit of "on the job training" going on with some operators. I am sure operating these things 24/7 has caused a bit of a personnel issue with experienced people.
One thing to note, these ROVs are huge machines. I have seen them work in tandem but they do it across from each other and I am sure they do it to share the views from the cameras to determine positions of tools etc. It gives them at least a better sense of depth. A stereo camera would not have any effect on the bots size or maneuverability. Its just two cameras rather that one that operate in tandem. The two camera views are from different angles and they are rendered by a computer to form a picture that has depth as well as the the two other dimensions of length and width. You would likely benefit by wearing video goggles or glasses as opposed to a screen, but they have recently started marketing 3-D screens as well. With this feature, they would not miss the cigar sized hole unless the ROV moved due to currents. Rather that ten attempts, they could do it it two. That is what I saw anyway...
Yes, I was getting pretty good with those seagulls. I hate to kill something that I don't eat however so I stopped doing it.:-)
