The control method includes displaying data through the ground terminal controller, processing environmental information collected by the detection module, determining the robot's working mode and switching working mode through the structure conversion module, adopting the ship-like working mode in deep water, and adopting the car-like working mode in the waterless or shallow water environment.

An underwater mobile observatory system comprising an aquarium able to hold water and large enough to support fish, coral, and to display artificial objects such as shipwrecks and ruins, a vehicle track extending through the aquarium the track generally being adjacent the bottom of the aquarium, the track having a portion which rises to a loading/unloading position, and a passenger vehicle coupled to the track for movement therealong and unable to leave the track such that changes in inclination of the track causes the vehicle to move up and down through water in the aquarium, the passenger vehicle having a main body portion to seat passengers and which is capable of being submerged, and a top portion which is open to the air, the spacing between the track and the water level being controlled such that water does not pass over the top portion.

A vehicle architecture and the associated method of operation for fixed wing aircraft transition from operation underwater to flight in air. More particularly, the vehicle architecture and method allows transition and long-range operation in both water and in air.

The method starts with the vehicle oriented for long range flight in water. The method is composed of a flight orientation change for high speed ascent by rolling over, then water ascent, tractor propeller transition, wing transition, pusher propeller transition, boundary layer flight, and air ascent. The vehicle will ascend in its highspeed water configuration. As the tractor propeller breaches the surface of the water it will change its pitch collectively to optimize for low speed operation in air. As the wings breach the surface of the water, they will increase in camber to optimize for low speed operation in air. The vehicle will change angle of attack to stay within the ground effect regime in air using firstly the submerged control surfaces. In ground regime flight the vehicle will accelerate and transition to high altitude low drag flight with optimally cambered wings.

A multifunctional all-terrain vehicle having a body for accommodating people and cargo, an engine, and a transmission having axles and wheels. Disposed on the axles are brake discs gripped within brake pads which are actuated by brake cylinders disposed in a carriage and forming a brake system, and can be used for traveling over land, water, swamps, snow. According to the invention, a single frame is configured as a three-dimensional structure, and waterproofing is additionally provided with a vertically adjustable seat.

An amphibious transport apparatus includes forward and aft ends, a pair of spaced apart pontoons including tracks, and a transversely extending structure, which can include a platform, that spans between the pontoons and connects the pontoons together. The amphibious transport apparatus further includes a sled vessel that can be used to transport materials or personnel. The sled can be releasably attached to the amphibious transport apparatus with tow bar and a pivotal connection. Said tow bar can be rotatable between an upper storage position wherein the tow bar engages the vessel away from said pivotal connection and above a terrain surface, and a lower towing position. A towing position of said amphibious craft and sled can be defined by the sled connected to the amphibious craft at the releasable pivotal connection, with the amphibious craft being self propelled with said tracks for engaging the underlying terrain and with the sled in the lower towing position so that the sled bottom drags along on the underlying terrain during movement of the amphibious transport apparatus and sled. A trailer for loading and unloading the sled can also be provided. The amphibious craft can push the sled onto the trailer during loading.

A vehicle is provided for drone stowage and transport as a means to extend the range of smaller drones and unmanned underwater vehicles. The transport vehicle is launched from a mother ship and provides for moving drones and underwater unmanned vehicles to desired launch and recovery points. The vehicle is based on current hovercraft vehicles and is adapted for stowage of drones while remaining compatible with existing mother ships. The vehicle includes foldable deck sections, which can be extended to provide launching and landing runways for flying drones. Lifts and ramps are incorporated for loading, launching and recovering flying drones, floating drone vessels and underwater unmanned vehicle drones.
