The development of navigation technologies for autonomous mobile equipment is pivotal to the intelligent upgrading of facility agriculture, with its core challenge being how to achieve safe, efficient, and precise movement within greenhouse environments. Through an in-depth analysis of the latest research trends, this study aims to comprehensively elucidate the evolution of these navigation technologies and discuss their future directions. We begin by reviewing the state of the art, with a focus on comparing the advantages and disadvantages of different navigation methods, including guide-rail, path-tracking, and multi-source data fusion navigation based on simultaneous localization and mapping (SLAM) technology. Furthermore, we explore recent advances in SLAM-based multi-source data fusion navigation for real-time localization, mapping, and path planning. Relevant research indicates that while traditional guide-rail and path-tracking methods are simple to implement, they suffer from fixed routes, high installation costs, and limited operational range. In contrast, SLAM-based multi-source data fusion navigation offers greater flexibility and autonomy, enabling precise localization, intelligent obstacle avoidance, and adaptive path planning, thus holding broad application prospects in facility agriculture. As SLAM technology continues to mature, equipment employing this navigation approach will see even wider adoption. This study also addresses practical challenges and limitations, such as computational demands and algorithm optimization. Finally, we propose several development prospects for China's facility agriculture: adopting multi-source data fusion navigation to achieve high-precision localization and mapping; integrating artificial intelligence, cloud computing, and edge computing to enhance the equipment's perception and understanding of complex environments; combining global and local path planning to enable autonomous decision-making; implementing intelligent obstacle avoidance to ensure operational safety and reliability; and investigating multi-vehicle and human-vehicle collaboration for efficient multi-task coordination. This research aims to provide valuable insights and references for the intelligent development of autonomous mobile equipment in Chinese facility agriculture.
