The underwater grabbing robot comprises a closed machine shell, a booster fixedly connected with the machine shell, a guide mechanism, a grabbing mechanism, a movable detection mechanism and a distance sensor. The machine shell comprises a main shell body, a rear cover and a front cover. The booster comprises a propeller and a servo motor for controlling the propeller to rotate, and is fixed on the rear cover; the guiding mechanism comprises three connecting rod wheel mechanisms which are driven by guiding air cylinders and evenly distributed in the circumferential direction of the robot. The grabbing mechanism is fixed to the front side of the machine shell and comprises a first five-freedom-degree mechanical arm and a two-finger manipulator fixed to the front end of the first five-freedom-degree mechanical arm. The movable detection mechanism is fixed to the front side of the machine shell and comprises a second five-freedom-degree mechanical arm, a laser scanner and a metal detector, wherein the laser scanner and the metal detector are fixed to the front end of the five-freedom-degree mechanical arm. The distance sensor is fixedly installed on the front cover of the machine shell. The method is suitable for grabbing the target objects such as metal pieces underwater, especially at the bottom of an underwater pipeline, the target object recognition precision is high, grabbing is reliable, and the application prospect is good.
