For visualising data in RVIZ is it necessary to launch the model in Gazebo first and then run RVIZ? Or is it possible to run RVIZ directly without launching Gazebo?
I am trying to visualise my robot (Motorman Sia10f) in RVIZ...but when I do so it's showing that there is no tf data and a warning in the Global Status.
Do I need to launch the model in Gazebo first and then run RVIZ?
What is the possible reason for this error?
