A vessel includes a body that floats in water. One or more thrusters and sensors are provided on the body. A controller is configured to selectively activate the thrusters to cause the vessel to move along a path through the water, receive sensor data from the one or more sensors while the vessel is moving along the path, determine, based on the sensor data, whether an obstacle or a dangerous condition is present in the water; control the thrusters to avoid the obstacle, and output a warning when the dangerous condition is present in the water. The collected sensor data may relate to locations and directions of currents in the water, the dangerous condition may relate to a rip current, and the warning may identify at least one attribute of the rip current. A map identifying a location of the dangerous condition may be generated and forwarded to other devices.

System for dangerous current identification, characterization, alerting and for distressed swimmer location and assistance

A vessel includes a body, such as surfboard, that floats in water. One or more thrusters, and one or more sensors are provided on the body. A controller is configured to selectively activate the thrusters to cause the vessel to move along a path through the water, receive sensor data from the one or more sensors while the vessel is moving along the path, determine, based on the sensor data, whether a dangerous condition is present in the water; and output a warning when the dangerous condition is present in the water. For example, the collected sensor data may relate to locations and directions of currents in the water, the dangerous condition may relate to a rip current, and the warning may identify at least one attribute of the rip current. A map identifying a location of the dangerous condition may be generated and forwarded to other devices.

A robotic mechanical fin, having a motor housing containing a plurality of rib rotation motors, rib spars, and a plurality of ribs, mechanically movable and communicatively coupled to the plurality of rib rotation motors and shafts, where the plurality of ribs are rotationally coupled to and actuated by the plurality of rib rotation motors and shafts. The mechanical fin further includes a flexible fin casing, within which the ribs reside, forming the complete actively controlled curvature robotic propulsion and steering apparatus. The mechanical fin is connected to a plurality of control electronics circuits and a computer processor programmed with actuation code that when executed by the computer processor causes automated actuation of simultaneous propulsion and steering maneuverability of the actively controlled curvature, robotic, mechanical fin.
