Abstract

A submersible ROV is provided with four independently controllable swivel thruster assemblies that allow the submersible ROV to simulate the movement of a person equipped with scuba gear. The submersible ROV receives control signals from a controller located on the surface of the water or on land. The submersible ROV senses and transmits audio and visual images and transmits those signals to a base receiver located on the surface of the water or on land. Signals are transmitted to and from the submersible ROV via a tether. The tether may be connected either directly to the controller/base receiver or may be connected to an intermediate floating ROV with a power supply and wireless communication relay station. A person can vicariously experience scuba diving via the submersible ROV while remaining dry and safe on land or on a surface vehicle.
