Feb 26, 2023 · When using ROS2 with Nav2, what function does AMCL and robot_localization serve? Do both of them estimate the robot position and publish the odom -> base_link transform? If yes, …

Nov 20, 2021 · SLAM can analysis the environment and locating iteself. And AMCL can locate itself with saved map. What difference between the two locating method of SLAM and AMCL? Because SLAM …

Apr 13, 2016 · AMCL is a global localization algorithm in the sense that it fuses LIDAR scan matching with a source of odometry to provide an estimate of the robot's pose w.r.t a global map reference …

Oct 29, 2016 · All, Seemingly dumb question. If I have a SLAM map feeding the Navigation Stack, and therefore localising itself then what purpose does the localisation provided by AMCL provide? Just to …
