A power management system comprises a remotely operated vehicle (ROV), a tether management system (TMS), and an umbilical operatively in communication with the TMS external electrical power interface and the TMS-to-ROV umbilical interface. The system can be configured to provide electrical power management that moves some or all of the electrical power required for ROV propulsion and tooling to the ROV and/or TMS, and maximizes available power and manages loads across all systems as necessary and by priority. Power management may also be required that features intelligent routing of power to subsystems and integration of variable frequency drives (VFDs).

The surface drive boat includes: a hull; transverse attitude-stabilizing thrusters and orbit vectored thrusters arranged at the bottom of the hull; a control box arranged on the hull and electrically connected with the transverse attitude-stabilizing thrusters and the orbit vectored thrusters; a cable and a cable winding assembly arranged on the hull, the control box being connected with the unmanned underwater vehicle by the cable, the cable winding assembly being electrically connected with the control box; and a positioning assembly arranged on the hull and electrically connected with the control box.

Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for automatic object detection for underwater cameras. In some implementations, an underwater camera captures many images which are obtained by a control unit. The control unit can detect one or more contours within a captured image based on values representing pixels of the image, generate a representation of the image based on the detected contours, provide the representation to a model that is trained to classify an input image as including a net or as not including a net, and perform an action based on classifying the image as including a net.

An underwater robot based on a variable-size auxiliary drive and a control method thereof includes a variable-size auxiliary drive module and a main control system. The variable-size auxiliary drive module includes a first variable-size silo, at least two first variable-size units and at least two first gasbags. The first variable-size silo has a first accommodating space with at least two first accommodating subspaces. Each of the first variable-size units includes a first micro push rod motor, a first push rod, a first push plate and a first gas guide tube. The first micro push rod motor, the first push rod and the first push plate are accommodated in the corresponding first accommodating subspace. The first push rod is fixed to the first push plate. one of the first gas guide tubes correspondingly communicates with one of the first accommodating subspaces and one of the first gasbags.

A modular mechanical arm of an underwater pile foundation structure includes a modular interface disposed at one end of the transmission arm rod, a mechanical arm connecting part disposed at the other end of the transmission arm rod. The mechanical arm connecting part is separately provided with two arm frames, each of the arm frames comprises an inner arm frame and an outer arm frame, the inner arm frame and the outer arm frame are coupled by a joint, and a soft moving and cleaning part is disposed on an inner side of each of the arm frames; the modular interface is coupled with an underwater UAV interface to transmit current and a control signal, a waterproof steering gear is built in the transmission arm rod to receive the control signal.

Disclosed is a compact, lightweight hydraulic manipulation system used for underwater applications consisting of two parts: a modulus hybrid underwater manipulator and a compact lightweight hydraulic control framework. The system is used for general underwater work such as underwater sampling, hyperbaric welding, and marine aquaculture.

A system and method for optical communication between multiple UUVs, more specifically, for leader-follower formations between UUVs. The system focuses on the characterization and modeling of a 1-dimensional and/or 3-dimensional light field produced from a light source mounted on a Leader UUV, which is detected by one or more follower UUVs. Communication algorithms are used to monitor the UUV's motion and orientation utilizing simulators, look up tables, and the like. A variety of detectors arrays can be used in a variety of wavelengths depending on the desired application.
