I am doing gazebo system plug in tutorial ( link )
After running the plugin, I suppose to have several pictures saved in /tmp/gazebo_frames directory. However, when I checked, I didn't even have such directory, let alone the frames.
Anyone has the same problem with me? What is the solution?
Side question: I know that gzserver is to run the gazebo server, but what does the & modifier do in gzserver & command?
