I can see the markers for a motion capture system in the video.

Measuring or accurately calculating the orientation at a rate high enough for this is a challenge in itself.

Underwater robotics PhD here. Completely seconded. Hardware is already complex. When the said hardware is mobile, complexity increases exponentially.

This is awesome! Is the OP the author?

Just started using rpi with my underwater robots. Obviously the wifi cuts off when they dive, but doesn't reconnect always when they come back. Will definitely try this out.
