Hey,

I'm creating a rosbag and want to record two topics into a .bag file. I am using a Python script to create this. The problem being is that I don't know whether or not I need to create a workspace, so then I could have the following command: rosrun project bag which would then record the topics or just have a script that I can run from terminal manually?

Thanks

Hello, use the command tool rosbag record -a to record in a bag file.

See: http://wiki.ros.org/rosbag/Tutorials/Recording%20and%20playing%20back%20data

If you really need the API for python, see: http://wiki.ros.org/rosbag/Code%20API where read and write from python to a bag file are detailled.

If you're just writing a single script you can use the default environments from your installation. By sourcing /opt/ros/DISTRO/setup.bash for the appropriate DISTRO.

If you're doing more you should create a workspace for your work.
