In recent years

China is making great efforts to develop aerospace industry. The building of flexible manufacturing units or production lines and the realization of rapid

flexible and automated production based on industrial robots play important roles in transforming and upgrading the production mode of aerospace manufacturing enterprises and upgrading equipment manufacturing capabilities and product performance. However

due to limitation of the structure of the base and environment

the absolute positioning accuracy of the industrial robot is low and the long-term stability is poor.Therefore

the industrial robot can not directly adapt to the applications and demands of various industries in the modern new manufacturing environment. This paper reviews and summarizes the current research methods and technologies in improving robot positioning accuracy at home and abroad

and puts forward the research ideas of improving the positioning accuracy of industrial robots. It has a certain guiding significance for the application and development of industrial robots in aerospace industry.
