“…For example, some solutions deployed in large-scale environments during the DARPA Subterranean Challenge (Hudson et al, 2021;Agha et al, 2021) led to the developments of new C-SLAM systems, such as the robust lidar-based approach of (Ebadi et al, 2020). Alternatively, (Schmuck et al, 2021) proposes a vision-based centralized C-SLAM system incorporating inertial measurements, which has been tested with up to 12 robots in simulation. In another line of work, (Lajoie et al, 2020) presents a distributed and decentralized system robust to spurious measurements, along with online experiments on real robots, and a publicly available implementation.…”
