Abstract: A modular underwater vehicle includes a hull having a series of modular sections, defining an interior housing, a propulsor coupled to a stern of the hull, a series of control surfaces coupled to the propulsor or the stern of the hull, and a power supply, a processor, and a nonvolatile memory device in the interior housing. The nonvolatile memory device has instructions stored therein which, when executed by the processor, cause the processor to supply power from the power supply to drive the propulsor and to actuate the plurality of control surfaces. At least one modular section of the series of modular sections is detachable.

Abstract: A marine seismic data acquisition system and method of conducting a marine seismic survey are disclosed. The system incorporates one or more surface vessels, and a plurality of autonomous nodes for acquiring seismic data at one or more seabed locations. Each node comprises a USBL, SSBL or SBL transducer and USBL, SSBL or SBL acoustic modem. A first acoustic positioning system is operable between one of the surface vessels and the nodes, the first acoustic positioning system being a USBL, SSBL or SBL system. Each node of the plurality of autonomous nodes has a USBL, SSBL or SBL beacon address, with respective groups of nodes having the same beacon address. The nodes are configured such that no two nodes with the same beacon address can actively communicate over an associated USBL, SSBL or SBL modem at the same time.

Abstract: An autonomous underwater vehicle includes a vehicle body controlled by a processor. An anchor joined to a tether is disposed in the vehicle. The vehicle has control surfaces for maneuvering, a propulsion unit, and a turbine. The propulsion unit and turbine generate thrust to propel the vehicle. A power source provides power to the vehicle. The turbine is further joined to a generator. When the processor detects that the power source is below a threshold value, the propulsion unit is stopped, the anchor is deployed, and the control surfaces are operated to move the vehicle in a predetermined trajectory through a fluid stream of the environment restrained by the tether. The fluid stream causes rotation of the turbine and generator to recharge the power source.

Abstract: An autonomous ship bottom inspection method by a ROV(s) based on a ship 3D model in STL format is provided. The ship 3D model is obtained and a surface thereof is spliced by triangular facets. Body 3D coordinate points of the ship 3D model are obtained and then expanded according to a safety distance of ROV and ship to obtain inspection track points of the ROV. The ship 3D model is divided into regions, and the inspection track points in each region are performed with interpolation and smoothing. Smoothed inspection track points of the regions are connected as per a result of the dividing to obtain a ship bottom inspection track, a real-time position of the ROV is obtained, a ship bottom inspection path is generated based on the ship bottom inspection track and the real-time position. The ROV is controlled to move as per the ship bottom inspection path.

Abstract: An underwater positioning system comprises a plurality of underwater beacons. A beacon, in response to a signal sent by an underwater vehicle, responds with a signal comprising one or more characteristics to identify the beacon. Components of an access algorithm are provided to the underwater vehicle. The access algorithm determines a location of the beacon based on the beacon's identity. A position of the vehicle is determined based at least in part on the location of the beacon.

Abstract: In a configurable vehicle a variety of mechanisms connect an external heat sink to an interior volume of the vehicle without creating a fluid conduit between the exterior and interior volume of the vehicle. Reliability of the vehicle is improved since exterior elements cannot penetrate to the interior of the vehicle.

Abstract: A power transmission device includes a power transmission coil, and a power transmission side processor. A power reception device includes a power reception coil receiving electric power from the power transmission coil, a power reception power supply charging the storage battery based on the received electric power and general-purpose power supply components, a power reception side processor periodically controlling a charging current to the storage battery, and a current sensor detecting the charging current. When a value of the charging current is outside a predetermined range, the power reception side processor calculates a feedback control parameter to the power transmission power supply based on a difference between the value of the charging current and a target current value, and transmits the feedback control parameter to the power transmission side processor. The power transmission side processor controls electric power from the power transmission power supply based on the feedback control parameter.
