Hi I'm running Ubuntu 12.04 and ros hydro,
I'm curently playing around with an ar drone with the tum_ardrone package. I wanted to know if theres a way to output data to a text file? I know I can use rostopic echo to get the data published to a terminal, but is there a way to get it somewere else?
I dont want to steal @bvbdort thunder, but I think you should probably save to a .bag file first and then change to a .txt or .csv file. Going directly to a text file, particularly if you are working with any imaging output from the bot can get weird quickly.
I believe the "ROS" way to do this would be to run a command like
$rosbag record <topic>
And then move it over to a .txt/.csv file. A useful script to do this can be found here: ( http://answers.ros.org/question/9102/... ) which converts to a .csv. This will save the data long-term and allow a cleaner transition in the short term.
To save data from ros topic to text file. It saves a .txt file in current directory,
rostopic echo /scan >>mydata.txt
Have looking into rosbag to save data and play it later.
