Web1 INTRODUCTION. An autonomous mobile robot requires a representation of its surroundings to localize itself relative to the environment. Simultaneous Localization and Mapping (SLAM) addresses this problem by incorporating the robot state estimation (pose and possibly other state variables) concurrently with the mapping process. WebThe/ekf_localization node uses the relative pose differences of each sensor to update the EKF for pose interpretation. In the navigation process, the main node is move_base, which pertains to the participation of the navigation control framework for robot path planning. monarchy background
