Deep sea operation robot

The invention discloses a deep sea operation robot. The robot comprises a ship body, a loading and unloading motor, an electromagnet and a straight guide rail. The straight guide rail is arranged on the ship body, the loading and unloading motor is movably mounted on the straight guide rail, an output shaft of the loading and unloading motor is connected with the electromagnet, the loading and unloading motor is used for driving the electromagnet to rotate on own axis, the electromagnet is used for adsorbing a to-be-disassembled part, and when the electromagnet rotates on own axis, the deep sea operation robot is used for controlling the loading and unloading motor to move along the straight guide rail; a to-be-disassembled component serving as a bolt is taken as an example, and after the electromagnet adsorbs the bolt, the bolt can be disassembled only by controlling the electromagnet to rotate and controlling the loading and unloading motor to move backwards. The electromagnet does not need to be accurately
