With the increasing need for map construction for unknown environments, multi-robot systems based on SLAM technology have become one of the research hotspots and focuses in the field of robotic systems today. According to the current research background for multi-robot SLAM technology systems, the researchers found that there are still research gaps in the limitations of traditional multi-robot SLAM technology systems. Therefore, this paper expands the related research to a deeper level, through the analysis of the existing research literature on multi-robot systems based on SLAM technology, explores the history of the continuous development and updating of this system as well as the working effect that has been able to be achieved under multi-interference or indoor complex environment, and based on which, searches for the possible optimization direction, and further puts forward the idea of the corresponding solution. The SLAM-based multi-robot cooperative interaction system can still be improved in many directions to realize more comprehensive functions.
