Multi differential gear train AGV fine positioning system and control method

This paper provides a multi-differential gear train AGV precise positioning system and control method, which solves the problems of poor autonomous positioning accuracy and low efficiency of multi-differential gear train AGV. The test results show that the positioning system and control method have low cost, simple structure and high precision. The angle error is less than ± 1 °, the horizontal and vertical error is less than ± 1mm, and the adaptability is strong. The positioning accuracy can be set freely, which is worth popularizing in large area on the differential gear train AGV.
