A multi-functional aquatic vehicle comprises a main body. The main body comprises: a propulsion system, comprising at least one propeller for changing a motion attitude of the main body; a camera system, comprising at least one camera; a communication system, comprising a signal receiving module for receiving an external signal detected by the aquatic vehicle and a signal transmitting module for transmitting a signal to an external control system; and a control system, for controlling an operating state of the propulsion system, adjusting a capturing angle of the camera system and controlling internal and external communication of the communication system. A towing hook device comprises: a driving system, a connecting mechanism and a towing hook mechanism. The driving system drives the connecting mechanism to rotate such that the towing hook mechanism turns over or rotates to release a load.

An underwater vehicle includes a plurality of releasable panel members that are initially in a storage state in which the releasable panel members form a closed housing and the underwater vehicle is neutrally buoyant, an actuatable effector that is retained in the closed housing. The effector has an anchor and a positively buoyant upper unit opposite the anchor. When the plurality of releasable panel members are released to open the closed housing, the effector is separable from the releasable panel members and maintained in a vertically downward direction by the anchor and the positively buoyant upper unit.

A small size subsea vehicle is designed to comprise the form of a subsea tool and include a common drive interface that allows quick connect/disconnect with the subsea vehicles (ROVs and AUVs). A subsea tool system comprising the small size subsea vehicle comprises a main vehicle 100 with a tool interface comprising a common drive interface 104a and a power interface 104b; and a subsea tool system 102 comprising predetermined footprint configured to fit within a predetermined space, e.g., one smaller than a narrow region or a constricted area where a larger subsea vehicle cannot enter due to size constraints of the larger subsea vehicle; a predetermined set of tools 103, each tool of the predetermined set of tools comprising a common drive interface 103a; and a tool repository 115.

A laser-powered ice-penetrating communications payload delivery vehicle for sub-ice submarine missions enables under-ice operations to exchange information with terrestrial facilities or satellite networks with communications methods otherwise blocked by an ice cap. The vehicle comprises an electronics bay, a payload bay, optics bay, and a melt optic with laser. The system and method of establishing communication where the vehicle, tethered to a sub-ice vessel, is released. The vehicle ascends to the bottom of an ice sheet and uses a laser to melt the ice, forming a borehole through which the vehicle continues to ascend. When buoyancy no longer advances the vehicle beyond sea level, the vehicle continues to melt a conical opening through the ice until unobstructed atmosphere is reached and bi-directional communication is established. Where the melting capacity cannot reach ice to continue melting, the vehicle mechanically advances itself toward the surface to establish high bandwidth, bi-directional communication.

An embodiment can include a vessel-towed system that includes a first towing/communication interface system, e.g., a first tow cable with a fiber optic system, and spaced apart buoys for supporting the first tow cable. A first mobile structure including a first control system and first type of emitter, e.g., an attraction system, is connected to the first tow cable. A second mobile structure is provided that can include an underwater towed emitter such as an audio emulation system. The first and second emitters can be configured emit a first and second plurality of emissions for inducing a receiving entity response. The second mobile structure is coupled with the first mobile structure with a second tow cable that comprises another fiber optic cable. An automated response or manual control systems can be provided on the towing vessel and the first mobile structure adapted to operate the first and second emitters.

Image recording as long as possible during one activity is required in deep sea exploration. Necessity of multi-directional image recording, optical and chemical observations and probing of mineral resources of seabed are also increased. There is no underwater exploration device enable these requirements. It is disclosed that at least one battery-driven underwater exploration body having three pressure-resistant hollow glass spheres for housing an image capturing device, an illumination device, a recording device, an acoustic communication device and a control device controlling thereof and at least one battery body having an approximately the same shape and structure as the underwater exploration body are connected with each other by a connecting tool to provide the connectedly-formed underwater exploration device.
