webots_ros2 is a package that provides the necessary interfaces to simulate a robot in the Webots open-source 3D robots simulator. It integrates with ROS2 using ROS2 messages, services and actions.

...This package uses one or more stereo cameras and optionally an IMU to estimate odometry as an input to navigation. It is GPU-accelerated to provide real-time, low-latency results in a robotics application. VSLAM provides an additional odometry source for mobile robots (ground-based) and can be the primary odometry source for drones. VSLAM provides a method for visually estimating the position of a robot relative to its start position, known as VO (visual odometry). This is particularly useful in environments where GPS is not available (such as indoors) or intermittent.

...It features several algorithmic innovations that increase speed, accuracy, and robustness of pose estimation in perceptually challenging environments and has been extensively tested on aerial and legged robots. This work was part of NASA JPL Team CoSTAR's research and development efforts for the DARPA Subterranean Challenge, in which DLO was the primary state estimation component for our fleet of autonomous aerial vehicles.

...We provide a fast scan-matching approach to mobile robot localization supported by a continuous likelihood field. It can be used to provide accurate localization for robots equipped with a laser and a not-so-good odometry. Nevertheless, good odometry is always recommended.
