A water submersible vehicle, the vehicle has a variable buoyancy system where flight of the submersible is controlled by a forward thruster forward of the center of displacement and that regulates both pitch and up-and-down hover. The vehicle in combination with a control system allows the user using to use only two control elements, one with each hand, to fly the vehicle by controlling motion along long axis, yaw, pitch and roll. An ergonomic submersible pod may be incorporated into the water submersible vehicle. The ergonomic submersible pod may also be used with other flight systems to provide for new types of low cost underwater travel.

Apparatus and methods are disclosed relating to a body towable behind a vessel in a body of water, an arm rotatably coupled to the body, and one or more foils disposed on the arm. The arm, when deployed, is configured to be free to rotate as the apparatus is towed through the body of water. The one or more foils are configured to generate lift as the apparatus is towed. Due to the free rotation of the arm, the foils impart tension force to the body and not torque forces.

An underwater vehicle includes a longitudinal body that defines a longitudinal axis and is rotatable about the longitudinal axis between a forward orientation and a sideways orientation, a wing attached to the longitudinal body that is moveable between a vertically extending wing orientation when the longitudinal body is in the forward orientation and a horizontally extending wing orientation when the longitudinal body is in the sideways orientation, a propulsion system having a front propulsion device and a rear propulsion device that is arranged rearwardly along the longitudinal axis relative to the front propulsion device, and an after-propulsion system arranged at a rear end of the longitudinal body that provides thrust along the longitudinal axis. The secondary propulsion system provides thrust in a perpendicular direction relative to the longitudinal axis.

A method for harnessing wave energy includes providing a vehicle to a body of water, the vehicle. The method includes submerging the vehicle to a depth in the body of water. The method includes operating the motor-generator of the vehicle in the first quadrant of the motor-generator. The method includes detecting a phase of a wave in the body of water based information from the processor of the detected phase. The method includes orienting the vehicle to lag the phase of the wave based on the detected phase of the wave. The method includes synchronizing an inertial acceleration of the vehicle to movement of the wave. The method includes switching the motor-generator to the second quadrant for generation mode to convert energy from the movement of the wave to electrical energy. The method includes storing the energy from the wave in the rechargeable battery source.

An underwater camera system includes a camera assembly configured to scan a seabed while submerged under water and moving in a direction of travel. A buoyant support is coupled to the camera assembly and configured to position the camera assembly under water during the moving in the direction of travel. A stabilization assembly is coupled to the camera assembly and configured for adjusting an orientation of the camera assembly relative to the direction of travel.
