Kyle on the joystick, as well as the tether means it is not autonomous.

Maybe this will help, but I won't hold my breath.

An AUV operates independently from the ship and has no connecting cables, whereas ROVs are connected to an operator on the ship.

There's a short video in the link below. It's so easy a caveman could understand it....if he wants to learn anything.
