System of unmanned underwater vehicles with multiple variable-geometry internally pressurized flexible hulls (that enable the underwater vehicle to submerge/emerge and change submersion depth by varying hull's buoyancy and not the vehicle weight) and possibly at least one pressure hull housing e.g. accumulators and electronic steering system. Each flexible hull is composed of a number of flexible hull segments modules.

The present disclosure discloses a wingless hydraulic extrusion spiral rotation and forward movement type intelligent unmanned underwater vehicle, including a cabin body and a control module. The cabin body includes a power reaction cabin and a power fuel storage cabin, a power reaction cabin water supply device is fixedly arranged on the cabin body. The power reaction cabin and the power fuel storage cabin are separated by a partition plate. Power fuel in the power fuel storage cabin may enter the power reaction cabin. A tail part of the power reaction cabin is provided with a jet forward propeller. The control module is fixed on the cabin body. At least two jet rotation propellers are arranged on the cabin body. The jet rotation propeller includes a main propelling pipe, an auxiliary propelling pipe, and a jet magnification ring. The jet magnification ring includes an outer ring and an inner ring.

A wheel-legged amphibious mobile robot with a variable attack angle, which belongs to the technical field of robot structure technology. The robot includes three parts: motion unit, body trunk and power unit. As a key structure, the motion unit mainly includes a moving mechanism, a wheel assembly, a telescopic mechanism and a transmission device. The robot drives the telescopic mechanism to reciprocate linearly through a gear and rack set, and pushes “legs” to expand and retract, so as to realize a mutual switching between a wheeled mode and a gait mode. Under transmission of bevel gear set, the blades can rotate at any same angle at the same time, to change the attack angle and realize the steering. The robot provided by the present disclosure can effectively adapt to a complex and harsh amphibious environment, and meet a series of operation requirements such as rapid movement, obstacle climbing, underwater steering.

A novel underwater robot water quality data acquisition device includes a casing, a thruster group, an upper cabin, a lower cabin, a buoy cabin, an upper cabin tray, a lower cabin tray, a power supply assembly, a power conditioning module, a data acquisition control module, a water quality sensor assembly, and a wireless Internet of Things (IoT) module. The device can convert the power supply voltage required by each other module through the power management module. The data acquisition control module transmits signals to the water quality sensor assembly in a set timing sequence, performs real-time reading and processing of water quality data fed back from the sensor, and uploads the processed water quality data to the data platform through the wireless IoT module, thereby achieving the display and preservation of water quality data.

A deep-ocean polymetallic nodule collector is an apparatus that is used to harvest polymetallic nodules and other natural resources from the ocean floor. To do so, the apparatus includes a support frame and a collection mechanism. The support frame is a durable structure designed to withstand the harsh deep-ocean conditions. The support frame keeps the collection mechanism adjacent to the ocean floor for the mining of polymetallic nodules without damage to the underwater ecosystem. In addition, the support frame allows for attachment of mining support vehicles that support the operation of the apparatus. The mining support vehicles can include, but are not limited to, cabled vehicles which are connected to the surface for power, monitoring, and control, wireless submersible vehicles, or ocean-bottom based vehicles that can operate autonomously, semi-autonomously, or by remote control. The collection mechanism enables the collection of polymetallic nodules while minimizing the damage to the underwater ecosystem.
