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.

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.

A motorized aquatic toy having a body with an attached articulated tail formed of pivotally connected hollow tail segments that maintain directional stability when water is flowing through and around them and having forward offset pivot points with mechanical stops that force contiguous tail segments to pivot in sequence from fore to aft in response to yawing of the body to simulate a life-like pattern of movement with a high level of realism.
