Hi,

what will happen if I rosbag record ROS topics and don't have enough memory to store it? Will rosbag overwrite something or will automatic shutdown command ?

Kind regards

Will rosbag overwrite something [..]?

you mean random other files on your file system?

No, that's not what will happen. I know of no program that would do that.


Edit: I've updated the title of your post, as "rosbag question" doesn't really capture what you really want to know -- and is too generic in any case.

I think the option --max-splits=MAX_SPLITS solves this problem for you:

Split bag at most MAX_SPLITS times, then begin deleting the oldest files. This creates a fixed size or duration recording.

rosbag record --split --size 1024 --max-splits 3 /chatter for size (in MB)

rosbag record --split --duration 10m --max-splits 6 /chatter for duration (in minutes)
