[0028] Embodiment 2: A connecting plate 25 is fixed to the bottom end of the base 8, and a first threaded sleeve 15 is fixed at the middle position of the bottom end of the connecting plate 25. The first screw 7 is movably connected to the inside of the top of the movable frame 6 in a transverse direction. The first servo motor 5 is fixed to the left side of the first screw 7.

The protective cover 2 and the door body 23 arranged on the outside can be used to externally close the working area of the robot on the top of the base plate 1 to prevent external personnel and equipment from approaching or entering the activity area, so that the explosion-proof robot can rotate freely and operate without obstruction. At the same time, when the explosion-proof robot is operating, the first servo motor 5 can be controlled to start and drive the first screw 7 to rotate. While the first screw 7 rotates, the first threaded sleeve 15 with a threaded connection can be used to drive the connecting plate 25 and the position of the top robot component to move left and right, so as to compensate for the displacement of the robot.
