An intelligent unmanned aquaculture robot comprises a ground station, remote control equipment, a hull part, a sailing controller, a feeding execution part, a bait casting controller, a data acquisition module, a data and image transmission module. The sailing controller receives instructions from the ground station, the remote controller or a shipborne panel, and is divided into a remote control mode and an automatic mode; the automatic mode completes scheduled sailing independently in an unmanned manner according to a preset route and a GPS (Global Position System) via real-time dynamic course control and velocity control, so that the fixed route is ensured; and the feeding velocity controlled dynamically in real time according to parameters such as real-time voyage, velocity and material quantity, so that uniform bait casting is ensured. The data and image transmission part transmits data collected by the data acquisition part and operating parameters related to a system to the ground station in real time. The robot can complete tasks such as the bait casting, fertilizing, spraying, seeding, mowing, oxygenating, pool patrolling, bird expelling, monitoring and the like independently. With the adoption of the robot, fixed quality, fixed points, fixed time and fixed quantity of large-scale aquaculture are realized, and the excess dependence of the aquiculture on the labor force is reduced.
