Mutual Localization

Mutual localization, the process by which multiple robots determine their relative positions, is crucial for collaborative robotics. Current research emphasizes robust and accurate solutions, focusing on algorithms that leverage various sensor modalities (e.g., cameras, UWB, IMUs) and address challenges like noisy data, limited sensor range, and time synchronization issues. These advancements utilize techniques such as hierarchical architectures, convex relaxation, and pose graph optimization to achieve high-precision localization, even in dynamic environments. Improved mutual localization significantly enhances the capabilities of multi-robot systems in applications ranging from swarm robotics to collaborative mapping and exploration.
