Flexible steering device for robot plate conveying and steering method of flexible steering device

The invention discloses a flexible steering device for robot plate conveying and a steering method of the flexible steering device, relates to the related field of robot steering, and aims to solve the technical problems that in the prior art, due to the fact that the upper end of a large gear is connected with a robot body, the robot body exerts the gravity effect on the large gear; when the pinion drives the bull gear to rotate, larger resistance is borne, the number of teeth of the pinion is small, abrasion of the pinion can be intensified when the bull gear with the large resistance is driven to rotate for a long time, and under the condition that the abrasion of the pinion is high, the condition of tooth sliding occurs when the bull gear is driven to rotate; and the ratio of the output speed to the actual speed does not accord with the preset ratio. An outer box body is arranged at the upper end of the base and is of a hollow structure, an upper fixing plate is fixed to the upper end of the outer box bod
