Is there a built-in solution for modeling delays for specific topics?

Hello ROS geniusses,

is there any built-in solution/possibility for modelling delays? I wanna simulate delays of several seconds on some topics, to model teleoperation. Does anybody of you know a good solution for that? It would be very nice if the topics could be chosen generically.

Thank you very much in advance.

Kind regards Cedric

I'm not aware of anything built-in (perhaps a bit out-of-scope, mixing responsibilities).

Perhaps you could look into using some tools that address this at the network level ( ). That doesn't give you 'topic level' granularity though.

Thank you so far, I've also come along similar thinks. Unfortunately that's not exactly what I was looking for. I've also found the topic_tools/throttle. We'll see if they can be useful for my task.
