Nothing. It's almost certainly autonomous, with cable control as a backup. Maintaining any sort of signal underwater at frequencies that allow decent bandwidth is hard. Basically impossible with consumer grade equipment. I worked in a related space while at GT, competing in the AUV/AUVSI competitions (not related at all to this lab - gatech has a large number of robotics teams/labs). We were getting the basics of cheap autonomous underwater vehicles down - vision, depth, INS, etc, and that was 10 - 15 years ago. It's a nice space since it's similar to control systems for flight, but much more forgiving on the time constraints. The biggest hurdle is always funding, since there's not really much market outside of the DoD or research grants.
