RVIZ Dropping messages

I was trying to setup the gazebo tf publisher for my own robot (ackermann steering vehicle) however for some reason I don’t get the lidar messages through to Rviz with the following message:

[rviz2-12] [INFO] [1678951875.772297900] [rviz2]: Message Filter dropping message: frame ‘lidar_link’ at time 16.169 for reason ‘Unknown’

Camera image comes through okay.

Any ideas what could be the issues?


Hi @roman.smid ,

Could you please provide more information:
Which Unit / Chapter you are working on?
Which Section of the Unit?
What is the Exercise (or Example) Number?

Although, I am not sure, could it be that you are using lidar_link instead of base_scan or base_lidar?


Hi @girishkumar.kannan ,

I am trying to apply what I learned in the TF course on my own robot.

This corresponds to the Chapter where we write the Gazebo TF publisher.
