The 13th Five-Year Plan for National Strategic Emerging Industries points out that basic theoretical research and core technology development should be promoted to realize the industrialization of humanoid neural computing chips， intelligent robots and intelligent application systems， and to embed new artificial intelligence technologies in various fields. China's manufacturing industry is in the stage of development from digital manufacturing to intelligent manufacturing. The intelligent application of industrial robots is the core technology of manufacturing transformation and upgrading. Firstly， by analyzing the application of industrial robots in different industries， the typical technical route of intelligent upgrading is determined. Secondly， the technologies involved in intelligent perception， pose estimation， compliance control and motion planning are reviewed and analyzed. Finally， the team's intelligent application of industrial robots in the fields of spraying， polishing， assembly， picking and other fields is taken as cases to analyze the innovative technical achievements in the integration process of artificial intelligence technology and industrial robot application， so as to provide case reference and technical guidance for the upgrading of intelligent manufacturing in different industries in China.
