The invention discloses an underwater feeding robot with a remote diving control function. The robot comprises an upper support plate, a storage box is fixed to the upper end of the upper support plate, and the upper end of the storage box is provided with two feeding ports and a motor; the two feeding ports are formed in both sides of the motor, the lower end of the upper support plate is fixedlyprovided with a motor A and two vertical plates, the motor A is positioned between the two vertical plates, an output shaft of the motor A is fixedly provided with a cam, the lower ends of the vertical plates are fixedly provided with a lower support plate, and the lower end of the lower support plate is fixedly provided with a sleeve and communicated with the sleeve. The lower end of the sleeveis fixedly provided with an arc-shaped cover body and communicated with the arc-shaped cover body, and the lower end of the arc-shaped cover body is fixedly provided with a box body and communicated with the box body. Discharge ports are formed in the two sides of the box body. A controller controls running of the whole robot to provide convenience for feeding fishes under water, and the effect isgood. Moreover, the robot cannot be influenced by water resistance, the situation that feed is dissolved and wasted after being soaked in the water for a long time is avoided, and pollution of the water is alleviated.
