Please help, thank you.

I've followed the [Troubleshooting Guide] but it doesn't solve the issue.

2. [slam_toolbox]: Message Filter dropping message: frame 'laser'
Try to up transform_timeout by 0.1 in linorobot2_navigation/config/slam.yaml until the warning is gone.

3. target_frame - frame does not exist
Check your <robot_type>.properties.urdf.xacro and ensure that there's no syntax errors or repeated decimal points.

Solved! I redid linorobot2_hardware and the issue solved.
