An aquatic rescue vehicle formed by adding directional and speed controls to a watercraft along with an autonomous control system to guide the vehicle to specified waypoints is disclosed. The rescue vehicle includes search devices such as a radio direction finder (RDF) and an infrared sensor (or camera) to be used to narrow the search for an isolated person (IP). The rescue vehicle may be discharged from a larger watercraft or an airplane and autonomously set out on its rescue mission. The vehicle may first navigate to a designated waypoint near an IP, and then use signals gathered from the RDF and infrared sensor to finally locate, assist, and retrieve the IP. The vehicle also includes a self-righting mechanism so that the vehicle can complete its mission even under the most adverse conditions.

A small watercraft includes: a watercraft body; a propulsion device that imparts the watercraft body with a propulsion force; a direction change device that changes a travel direction of the watercraft body; and a control unit that sets a destination of the watercraft body and executes automatic navigation control of controlling the propulsion device and the direction change device so that the watercraft body moves toward the set destination. The control unit varies control patterns of the propulsion device and the direction change device in the automatic navigation control depending on a combination of an angular difference between a destination direction that is a direction from the watercraft body toward the destination and a travel direction of the watercraft body, and a separation distance from the watercraft body to the destination.

In an information processing method for remotely controlling a marine vessel using a mobile terminal, the mobile terminal detects that the mobile terminal is tilted from a neutral posture. Then, in response to detecting that the mobile terminal is tilted from the neutral posture, the mobile terminal transmits, to the marine vessel, a command for generating a propulsive force corresponding to at least one of a plurality of propulsion directions including a propulsion direction for translating the marine vessel in the front-rear direction, a propulsion direction for translating the marine vessel in the left-right direction, and a propulsion direction for turning the marine vessel in the left-right direction.

The present disclosure relates to the technical field of decision-making of unmanned surface vehicles, and provides a brain-like memory-based environment perception and decision-making method and system for an unmanned surface vehicle. The method includes: obtaining an image of an environment in front of an unmanned surface vehicle; and inputting the image of the environment into an environment perception and decision-making model of the unmanned surface vehicle, and outputting an action instruction, where the environment perception and decision-making model of the unmanned surface vehicle includes an image feature extractor, a Bidirectional Encoder Representations from Transformers (BERT) model, a fully connected layer, a short-term scene memory module, and a long-term memory module that are connected in turn; the BERT model extracts an image feature representation containing a text feature from an image feature. The present disclosure improves accuracy of decision-making of an action.

A station keeping waterfowl system includes at least one self propelled station keeping waterfowl decoy and a homing buoy each having water resistant housings, with at least a portion of the decoy housing having a form of a waterfowl. The decoy and buoy each include batteries, microprocessors, and power switches. The decoy includes a motor driven propeller, a motor driven rudder, and a receiving array of antennae for radio direction finding and radio ranging to the buoy. The receiving array is a T-array of antennae comprising a first transverse linear array and a second longitudinal linear array. The homing buoy emits a homing signal and the one or more waterfowl decoys autonomously navigate to remain within a predetermined radius around the buoy. The system includes a simple handheld controller which preferably comprises no more than two switches or buttons.

A dynamic active control system configured for counteracting dynamic motions of a marine vessel. The system may include at least one sensor, a plurality of water engagement devices, and a software module.

A dynamic active control system configured for total pitch and roll control based on desired marine vessel pitch and roll angles. The system may include at least one sensor, a plurality of water engagement devices, at least one engine and a software module. At least one of water engagement device delta symmetrical deployment and engine trim adjustment facilitate pitch control and water engagement delta positions facilitate roll control.
