### Turtlebot3 Nav2, 2D LiDAR SLAM with FusionCore (IMU + wheel UKF)
[turtlebot3_sim_fusioncore_icp_demo.launch.py](https://github.com/introlab/rtabmap_ros/blob/ros2/rtabmap_demos/launch/turtlebot3/fusioncore/turtlebot3_sim_fusioncore_icp_demo.launch.py) (Jazzy + Gazebo Harmonic)

FusionCore (wheel + IMU UKF) and `icp_odometry` run in a feedback loop: FusionCore's stable `odom` frame seeds scan matching via `guess_frame_id`, and the ICP result feeds back into FusionCore as a second velocity source. See [README](launch/turtlebot3/fusioncore/README.md) for architecture details.
