A callback wrapper for rosbag record, where a ros service allows a user to start recording a set of topics and also stop.
Three arguments have to be over-written in your own launch file;
- path_save: system dependent path to folder where all the rosbags will be put: /home/user/rosbag_record
- topic: set of space sperated topics: topic1 topic2 topic3 ...
- file_name: the name prefix which will be put before the rosbag time stamp (optional)
