A computing apparatus that is integrated within a flotation module, the system obtaining the energy required to power its computing operations from waves that travel across the surface of a body of water on which the flotation module sets. Additionally, the self-powered computing apparatus employs novel designs to utilize its close proximity to the body of water and/or to strong ocean winds to significantly lower the cost and complexity of cooling their computing circuits.

An offshore node deployment system includes a control system, a surface vessel including a deck, and a propulsion system in signal communication with the control system, a node storage container supported by the deck of the surface vessel, wherein the node storage container is configured to store a plurality of nodes which are physically disconnected from each other, and a node deployment system supported by the deck of the surface vessel and controllable by the control system, wherein the node deployment system is configured to retrieve the nodes from the node storage container and deploy the nodes to a subsea location.

An efficient path planning method for a robot used for collecting marine debris includes: traversing all target positions of the marine debris by depth-first search (DFS) to generate a target position sequence; and calculating a target position with a lowest total cost by a path planning algorithm, and setting the target position with the lowest total cost as a next target position to be traversed for the robot. The efficient path planning method can plan an optimal or near-optimal cleaning path for the robot based on real-time environmental information, reducing unnecessary path repetition and ineffective motion, thereby significantly improving the cleaning efficiency.

A remote launcher includes a base frame, a cradle, a cradle actuator, and a launch control system. The cradle is pivotably coupled to the base frame and includes one or more skids that are configured to receive and support an unmanned water-based deployable. The cradle actuator is coupled to the base frame and to the cradle. The launch control system includes a communication interface, a processor, and memory having instructions. The instructions direct the launch control system to receive, via the communication interface, one or more wireless launch signals and then, in response thereto, generate at least one cradle control signal to enable the cradle actuator to incline the cradle to a launch angle.

The present embodiment provides a method and an apparatus for matching a ship map of a moving ship and a harbor map of a harbor terminal, capable of connecting the ship map to the harbor map, in transferring an autonomous driving vehicle using a ship from a harbor to another harbor, in order to use the harbor map and the ship map, similarly to control of the autonomous driving vehicle on a road.

Various examples are provided related to autonomous unmanned drone-tethered sonar systems. In one embodiment, a bathy-drone system includes an unmanned payload vessel and an unmanned drone tethered to the payload vessel through the tether attachment point. The unmanned payload vessel can include a sensor or sensor suite coupled to a bottom of the payload vessel and a tether attachment point through which propulsive force can be applied to the payload vessel. The drone can autonomously transport the payload vessel to and from a survey location and autonomously propel the payload vessel along a survey path at the survey location.
