Oh yeah, I get that the shots aren’t continuous between the POV footage and the cutaways
My point was more why would it need to rotate if they only ever used stable footage? I still contend they made a robust, workable camera-disguised-as-otter for the main footage, and a separate cutesy floating robot, that needn’t even have a working camera in it, for the cutaway shots.
Maybe I’m being overly cynical, but I’m sure the cameraman who had to sit there for months gathering the POV footage didn’t want the hassle of robotics that were sure to break down all the time. Much easier to use the ‘A’ otter that he knew would do the job, and just come in with the ‘B’ otter (the stunt otter 
) for a week or so and film it interacting once you’re done gathering all the POV footage.
Not that I think it detracts from the narrative of the documentary at all, I’m just thinking about it logistically. Maybe I’m totally wrong, but that’s how I’d do it if I were producing the show.
