This application provides an intelligent robot for cleaning and mending a net cage and a method of using the intelligent robot, including: a control system, a main body, an attraction module, a motion module, a cleaning module and a mending module. The main body includes a streamlined pressure casing, and a drive mechanism and a water ballast tank which are located in the pressure casing. The attraction module includes electromagnets which are symmetrically provided at a bottom of the pressure casing. The motion module includes first and second motion mechanisms which are symmetrically provided at opposite sides of the pressure casing. A traveling path of the first motion mechanisms is perpendicular to a traveling path of the second motion mechanisms. The intelligent robot achieves cleaning and mending for both sides of the net cage, and is simple to operate, safe, high-efficient, economical and convenient.

A recovery device for an unmanned underwater vehicle (UUV) includes a first recovery component arranged on an unmanned ship and a second recovery component arranged on the UUV. Two magnets are provided on an end of the first recovery component and an end of the second recovery component which are opposite to each other, respectively. A first cable of the unmanned ship is provided on an end of the first recovery component away from the magnet, and a second cable is provided on an end of the second recovery component away from the magnet. A thruster is provided on a side of the first recovery component. The UUV is recovered using the unmanned ship through the recovery components connected to the cables, which allows the locating and navigation errors to a large extent.
