A submersible node and a method and system for using the node to acquire data, including seismic data is disclosed. The node incorporates a buoyancy system to provide propulsion for the node between respective landed locations by varying the buoyancy between positive and negative. A first acoustic positioning system is used to facilitate positioning of a node when landing and a second acoustic positioning system is used to facilitate a node transiting between respective target landed locations.

An electrically-powered unmanned marine vehicle and method of making same, including providing a hull of the marine vehicle and mounting a submersible electric thruster to the hull via a mounting interface of the thruster. The thruster includes a stator assembly and a rotor assembly. The rotor assembly forms an internal cavity with a plurality of magnets arranged radially outwardly of the internal cavity. The stator assembly includes electrical windings that are disposed within the internal cavity of the rotor assembly. The thruster is configured to allow the internal cavity to be flooded with water when the thruster is submerged, and the electrical windings are encapsulated with a protective barrier that prevents the flooded water from contacting the windings. The thruster of the marine vehicle is thus water cooled, and the electromotive forces provided by the windings generate sufficient thrust to propel the marine vehicle through the water.

Disclosed is a vessel with a semi automatic or automatic vessel mooring system and a method of mooring with such a system. The vessel includes a hull, a mooring line winch unit, at least one mooring line extending from said winch unit, and a weight at an end of the at least one mooring line. A mooring line guide boom with at least one mooring line guide on a mooring line guide portion is movable between a retracted position aligned with the hull, and an extended position. In the extended position the mooring line guide boom allows the winch unit to lower the weight at the end of the mooring line extending through the mooring line guide and onto a quay.

Provided is a mobile water quality monitoring platform for a fishpond, belonging to the technical field of water quality monitoring devices. The mobile water quality monitoring platform for a fishpond includes a floating body, a first rotating shaft and a second rotating shaft are disposed on the floating body, the first rotating shaft is rotatably disposed on the floating body through two first support plates, two second support plates are vertically disposed on the floating body, an elongated chute hole is horizontally disposed on two second support plates respectively, both ends of the second rotating shaft are inserted into two chute holes respectively, the first rotating shaft and the second rotating shaft are connected through a connecting rod mechanism, a driving mechanism that enables the first rotating shaft and the second rotating shaft to rotate simultaneously is disposed on the connecting rod mechanism.

The present disclosure provides a lampshade structure, an unmanned aerial vehicle (UAV) arm, a UAV, and a movable platform. The lampshade structure may comprise a first light-transmitting surface of a lampshade body close to a light-emitting element and a second light-transmitting surface of the lampshade body away from the light-emitting element; wherein the first light-transmitting surface may include a scattering structure to outwardly refract light emitted by the light-emitting element to expand a light-emitting angle and an irradiation direction of the light-emitting element, thereby obtaining sufficient light in a desired direction.

A self-righting unmanned vehicle, comprising: a cavity 1, located at a first side of the hull of the unmanned vehicle; a sealed cavity 2, located at a second side of the hull of the unmanned vehicle and provided, in parallel to the cavity 1, in a head region of the hull; and a first propeller 3, provided in a tail intersection region of a normal waterline A with an inversion waterline B of the unmanned vehicle, and rotating in a reverse direction when the unmanned vehicle is in an overturned state. The self-righting unmanned vehicle improves the self-righting efficiency of the unmanned vehicle.

Many different types of systems are utilized or tasks are performed in a marine environment. The present invention provides various configurations of unmanned vehicles, or drones, that can be operated and/or controlled for such systems or tasks. One or more unmanned vehicles can be integrated with a dedicated marine electronic device of a marine vessel for autonomous control and operation. Additionally or alternatively, the unmanned vehicle can be manually remote operated during use in the marine environment. Such unmanned vehicles can be utilized in many different marine environment systems or tasks, including, for example, navigation, sonar, radar, search and rescue, video streaming, alert functionality, among many others. However, as contemplated by the present invention, the marine environment provides many unique challenges that may be accounted for with operation and control of an unmanned vehicle.

An air, sea and underwater tilt tri-rotor UAV capable of performing vertical take-off and landing. By the method for controlling a submerged floating device and a tilt tri-rotor device, the UAV is switched among the vertical take-off and landing mode, fixed wing mode, water surface sailing mode and underwater submerging mode.

The present invention is broadly directed to an unmanned surface vessel (USV) 10 broadly comprising: 1. a vessel body (12) adapted to contain a payload (14); 2. a front fin (16) and a rear fin (18) connected to and protruding from the vessel body (12); 3. a forward foil (20) and a rearward foil (22) connected to a distal end region of the respective front and rear fins (16) and (18); 4. propulsion means (24) operatively coupled to the rear fin (18) for propulsion of the fin (18) and the foil (22) through the water.
