get it,for me is 
python3 uorb_to_ros_msgs.py ~/PX4-Autopilot/msg/ ~/px4_ros_com_ros2/src/px4_msgs/msg/
Just fyi, documentation for ROS2 was finally updated recently!
Hi @Benja, the file uorb_to_ros_msgs.py doesn’t seem to exist in the current branch. Any alternative to this file or can you let me know the branch in which it is present?
TIA
That file exists up to version v1.13 and it is used for microRTPS
You won’t find it in main and v1.14 as it is not needed anymore
Oh, I want to use the UORB message ActuatorMotors to give the commands to motors in SITL. I am using PX4-Autopilot v1.14.0 branch and I want to do this using the ROS2 interface with PX4 as given in ROS2 User Guide . I read in this that I will be able to only use the topics that are mentioned in the ‘dds_topics.yaml’.
Since the ‘ActuatorMotors’ msg and the corresponding topic are not listed in the dds_topics.yaml after I build my PX4 directory, I want to know if there is any way to manually add the topic and use the msg to accomplish my task. Can you please help me how to proceed with this?
TIA.
