The invention provides a hot-line robot with double mechanical arms, and coordination control over the double mechanical arms is achieved. The hot-line robot with the double mechanical arms comprises the first mechanical arm, the second mechanical arm, binocular cameras, panoramic cameras, a main manipulator, a driving control cabinet, a driven control cabinet and a displayer. The first mechanical arm and the second mechanical arm are each provided with one binocular camera. A second industrial personal computer is externally connected with a working mode selector switch and used for determining a current working mode of a double mechanical arm control system, and the working modes comprise the teleoperation mode and the autonomous working mode. Based on the teleoperation working mode, the double mechanical arm coordination control system with the autonomous operation working function and a method of the double mechanical arm coordination control system are provided; and by the adoption of the autonomous working mode, on one hand, safety of operators can be guaranteed, on the other hand, misoperation can be reduced, and the operation efficiency and operation quality are improved.
