programatically create subscribers
I am trying to make a simple logger that given a list of topics via a service or an action, subscribes to and logs the data from these topics. This requires me to initiate subscribers on the fly and the callback data handlers are proving not easy to get around. Any ideas?
Have you looked at rosbag?
Yes, but what we need goes beyond rosbag, we need to be able to process the data independent of ROS
