Cannot convert bag to rawlog

[aaravrav142]

Hi,

I am using the mrpt 1.5 installed from PPA on a fresh ubuntu 16.04 install with ROS kinetic. I have all the mrpt ros packages in my catkin workspace and have them build successfully. The MRPT is working as I can open the sample apps like RawLogViewer etc from the command line.

I am following the the tutorial to convert the given bag filte to the rawlog format for further analysis. The bag file comes with the mrpt ros packages inside the mrpt_rawlog/tutorial folder (driving_in_office.bag). However, the rawlog does not get saved properly. I always get stream of continuous info messages as $rosrun mrpt_rawlog rawlog_record_node scan:=/r1/front_laser/scan _odom_frame_id:=r1/odom _base_frame_id:=r1/base_link _raw_log_folder:=/home/arav/Documents/

 Problem to syn data for sensor frame!

INFO: pRawLog    entries 0

I have tried this with other bag files containing topics such as scan, odom and tf but getting same results as below: $ rosrun mrpt_rawlog rawlog_record_node scan:=/scan _odom_frame_id:=odom _base_frame_id:=/base_link _raw_log_folder:=/home/arav/Documents/

INFO: pRawLog    entries 1093

ERROR: Error writing to _home_arav_Documents_/2019_08_22,23_35_40.384428ros_log_asf.rawlog

I have successfully used it before when I was using ROS indigo with the ubuntu 14 but on Kinetic this does not work. All our PCs were upgraded to ubuntu 16 so I cannot revert back now. Tested it with MRPT 1.9 as well and getting same result.

Can you help with this because I urgently need to analyse the rawlog to finish my project.

Thanks

I get a similar problem too. At first, it gives the following error:

I should note that I get that error using the latest branch, melodic, MRPT 1.5, Ubuntu 18.04. I get exactly like @aaravrav142 on 0.1.24 though.

[hoonkai]

Fixed. I just had to turn down the playback rate.

[aaravrav142]

@hoonkai did you get the rawlog generated in the end?

[aaravrav142]

I am still facing the same problem with fresh install of mrpt 1.9 and mrpt ros pkgs. No msgs been recorded after playing the rosbag. Should I try melodic for a change?? Any help is deeply appreciated. Thanks

I will probably remove rawlog_record from this package in a subsequent release, since there is a more modern and flexible way to doing it via the upstream's app rosbag2rawlog from package Ubuntu native package mrpt-apps or from ROS package ros-${ROS_DISTRO}-mrpt2. To do:

• [x] Add proper docs and tutorial to https://docs.mrpt.org on rosbag2rawlog.
• [x] Remove rawlog_record from this repo.

======== Update Aug 2023: rosbag2rawlog upstream, and in ros-$ROS_DISTRO-mrpt2 is now ready for ROS2.

For the records:

• ROS1 -> .rawlog: use mrpt2/rosbag2rawlog
• ROS2 -> .rawlog: use mrpt_navigation/mrpt_rawlog rosbag2rawlog version
