The invention relates to the technical field of propellers, and discloses a novel underwater robot propeller which comprises a propeller body, the propeller body is cylindrical, a cavity is formed in the propeller body, a spraying part is arranged at one end of the propeller body, a spraying hole is formed in the spraying part, and the spraying hole is connected with the cavity of the propeller body in a penetrating mode; a piston is arranged in a cavity of the propeller body, and the outer side wall of the piston is connected with the inner wall of the propeller body in a sliding and sealing mode. A driving mechanism for driving the piston to move is arranged on one side, far away from the spraying hole, of the piston; the driving mechanism comprises a motor, the motor is fixedly installed in the propeller body, a second gear is installed on an output shaft of the motor, a first gear is arranged between the piston and the motor, and the first gear is connected to the inner wall of the propeller body through a shaft rod. According to the novel propeller, the propelling effect is achieved through reciprocating motion of the piston, the problem that an existing propeller needs a protective net is well solved, and cost is greatly saved.
