About

Ruohai Ge is a robotics researcher whose work centers on advancing long-term autonomy and visual localization for robotic systems. Their major contributions address the critical challenge of enabling robots to reliably navigate and understand their environment over extended periods and across large spatial scales. Ge’s most notable work, the 2022 paper "ALITA: A Large-scale Incremental Dataset for Long-term Autonomy," directly tackles the limitations of existing place recognition methods, which are often tested only in simplified or simulated settings. By introducing a real-world, large-scale incremental dataset, Ge provides a more rigorous benchmark for evaluating Simultaneous Localization and Mapping (SLAM) systems, a foundational technology for autonomous navigation. This work has garnered 8 citations, reflecting its growing importance in the field. More recently, in 2025, Ge introduced "iLoc: An Adaptive, Efficient, and Robust Visual Localization System," which aims to enhance the adaptability of robotic agents in long-term, large-scale applications. This innovative system represents a significant step toward more resilient and practical autonomous robots. Through these contributions, Ruohai Ge is helping to bridge the gap between theoretical SLAM research and real-world deployment.
