Multi-robot SLAM systems in GPS-denied environments require loop closures to maintain a drift-free centralized map. With an increasing number of robots and size of the environment, checking and computing the transformation for all the loop closure candidates becomes computationally infeasible. In this work, we describe a loop closure module that is able to prioritize which loop closures to compute based on the underlying pose graph, the proximity to known beacons, and the characteristics of the…

Present and Future of SLAM in Extreme Underground Environments
The state of the art in underground SLAM is reported on by discussing different SLAM strategies and results across six teams that participated in the three-year-long SubT competition, with particular emphasis on LIDAR-centric SLAM solutions.
LAMP 2.0: A Robust Multi-Robot SLAM System for Operation in Challenging Large-Scale Underground Environments
This letter reports on a multi-robot SLAM system developed by team CoSTAR in the context of the DARPA Subterranean Challenge, and extends the previous work, LAMP, by incorporating a single-ro Bot front-end interface that is adaptable to different odometry sources and lidar configurations.
