Current /kobuki/laser/scan not ready yet

When using the ROS Development Studio and following the tutorial at http://www.theconstructsim.com/ros-pr... , I can not get it to work. Running roslaunch turtle2_openai_ros_example start_training.launch only leads to the warning:

[ERROR] [1554815151.623766]: Current /kobuki/laser/scan not ready yet, retrying for getting laser_scan

The same happens when I try to run the link with the code generated in the tutorial, instead of trying to set it up myself.

Seeing as you're using the RDS, this would be something to ask The Construct. ROS Answers is not necessarily a support channel for the RDS.

I am having the same problem and I found a solution by using depthimage_to_laserscan package to get the topic /scan from /camera/depth/image_raw. Also you have to remap from /scan (depthimage_to_laserscan output) to /kobuki/laser/scan.

Here you have detailed info about the package https://wiki.ros.org/depthimage_to_la...

best!
