An underwater and aerial vehicle includes a fixing frame, a core navigation system and an energy supply system. The fixing frame has a circular ring configuration in a middle part thereof, and the waterproof sealing cabin is fixed in the circular ring configuration, and multiple cantilever arms extend around the circular ring configuration. An underwater navigation control module and a relay are provided on an auxiliary fixing platform. A second brushless motor is provided on each of the cantilever arms. Each second brushless motor is provided with a marine propeller. A flight control module, a remote control receiver and a power management module are provided on a fixing platform. A first brushless motor is provided on each of the cantilever arms. Each first brushless motor is provided with a rotor via a coupling. The energy supply system is arranged in a lower part of the waterproof sealing cabin.

An underwater ROV or AUV with 8 vectored thrusters that provides a high degree of dynamic stabilisation, 6-degrees of freedom, and a system to control an underwater ROV or AUV with single or multiple thruster failures. In addition, the ROV/AUV has a system to minimise silt disturbance when operating close to fine silt or sensitive environments.

Reconfigurable vehicles, methods of configuring modular vehicles are provided. Vehicles may have modules that may be coupled to the vehicle at discrete positions and at discrete angles. Configurations for the modular vehicles may be further determined automatically depending on desired vehicle characteristics. Modular vehicles may be configured manually, and a predicted vehicle characteristic may be determined.

An underwater vehicle comprising: port and starboard thrusters spaced apart in a port- starboard direction, each thruster being oriented to generate a thrust force in a fore-aft direction perpendicular to the port-starboard direction; a vertical thruster which is oriented to generate a thrust force substantially perpendicular to the fore-aft and port- starboard directions; port, starboard and vertical ducts which contain the port, starboard and vertical thrusters respectively, each duct providing a channel for water to flow through its respective thruster; and a moving mass which can be moved relative to the thrusters in the fore-aft direction to control a pitch of the underwater vehicle.

A system of connectable aerial vehicles. The system includes a plurality of aerial vehicles that each include a platform, one or more rotors operatively connected to the platform, and a power source that supplies power to the one or more rotors. The plurality of aerial vehicles are configured to operate in air, and operate in water while connected to form a floating platform. The floating platform is configured to support an object with at least a portion of each of the plurality of aerial vehicles configured to form a segment of the floating platform.

The present invention provides an underwater moving vehicle improved in motion performance and capable of stably maintaining its position.

[Solution]

An underwater moving vehicle comprising: a vehicle body (1) configured to be set in advance in such a manner that weight of the vehicle body (1) becomes larger than buoyant force generated in water; a thruster (32) configured to generate an upward thrust by driving screw propellers (21); a drive adjuster (50) configured to control water depth of the vehicle body (1) to a predetermined position by adjusting drive of the screw propellers (21) and generating the upward thrust equivalent to difference between the weight and the buoyant force; and a water flow deflector (34) configured to move the vehicle body (1) in a horizontal direction by deflecting a downward water flow generated by the screw propellers (21).
