The NR-1 Submarine
Two retractable, rubber-tired bottoming wheels provide a means for maintaining a fixed distance between the box keel and the seabed, facilitating movement on the bottom and while working the manipulator. Wells in the keel accomodate the wheels when not in use, and allow the wheels to retract under excessive loads.
