An unmanned vehicle including a body and a frame structure extending from the body and supporting a plurality of propeller assemblies, each propeller assembly including at least one propeller and a corresponding motor with the motor housed in a watertight housing or coated and made corrosion resistant. The propellers comprise a first subset of propellers of the propeller assemblies and a second subset of propellers of the propeller assemblies which rotate in a plane positioned below a plane in which the first subset of propellers rotate, wherein said first and second subset of propellers are configured for independent operation of one another as the vehicle transitions from an air medium to a water medium.

The system is a type of gliding device capable of gliding through different mediums, such as water. The body of the gliding device is comprised of buoyant material and is ideally chosen based on the best material to utilize the hydrographic printing process. The body encourages the system to rise in water and wings extend from the body and resist vertical motion providing little resistance to forward motion. A third wing may extend from the distal end of the body and have a rudder pivotably connected thereto, allowing a user to manipulate the flight path of the system through the water while the system slowly rises to the surface.

A self-rotating display device (1) includes and outer light transmissive container (2) containing a light transmissive fluid (6) and a body (4) containing an electric motor (14) for rotating the body with respect to the outer container. The body also carries a compass magnet (18) as a source of counter-torque for the motor to operate against. A magnetic positioning structure (20) made of ferromagnetic material secured to the container interacts with the magnetic field of the compass magnet to cause the body to migrate toward a location minimizing the distance between the magnetic positioning structure and compass magnet, so that the body can remain centered within the display while rotating.

A self-rotating display device includes and outer light transmissive container (402) containing a light transmissive fluid (406) and an body (404) containing an electric motor (421) for rotating the body with respect to the outer container. The body also carries an amount of the fluid (430a) contacting the fluid in the outer container through a pressure equalizing gap (431) in the body which forms a fluid pathway between the inner cavity of the body and the inner chamber of the outer container. The fluid pathway forms self-regulating pressure relief structure which accommodates slight pressure variations in the fluid due to climactic conditions for example. A specialized reduced footprint fluid-immersible electric motor having separate field and compass magnets, which do not rotate relative to each other, helps eliminate magnetic cogging. The device can be manufactured according to a method which eliminates the necessity of a fill hole in the body.
