ros2 bag play simulation problems
Hi everyone,
I'm trying to record all the information needed for a navigation problem. To this purpose, I've checked all the topics that are involved by executing
ros2 topic list
and, after that, I've recorded them with the ros2 bag tool.
When playing this utility with the recorded information, although the robot's behavior on Rviz seems to be ok, on Gazebo is random.
I've checked that the /initialpose
topic is ok and that the recorded topics' QoS are also settled properly.
Thanks in advance.
On Gazebo, I receive the warning
[robot_state_publisher-3] [WARN] [1668532897.204232561] [robot_state_publisher]: Moved backwards in time, re-publishing joint transforms!

I’m new to gazebo, but can afford a guess:
1) Gazebo sim starts up setting some “current sim time”.
2) Your play from bag issues recorded topics (having time stamps of prior sim times).
3) Gazebo resets “sim time” to the time stamp of the first topic.

Thanks @RobotDreams! so, should I ignore Gazebo?
