Abstract: Currently the application of multi-robot scheduling systems in the field of intelligent manufacturing is increasingly widespread, which can significantly enhance production efficiency and product quality of manufacturing enterprises while reducing labor costs. However, the technical scope involved in multi-robot scheduling systems is extensive and complex, posing significant challenges for research and implementation. Therefore, this study focuses on classifying multi-robot scheduling systems based on their application forms and conducting a detailed survey analysis of the current research status. Building upon this, the key technologies relevant to multi-robot systems are explored. Finally, the existing issues and future development trends are analyzed. The findings of this research provide valuable insights for the application of multi-robot scheduling systems in intelligent manufacturing.
