I am creating subscriber and publishers for the turtle bot robot. For most topics, after using rosinit, I can create properly
publishers and subscribers. However, I fail to create a publisher for the /sound topic.
For instance, for topic cmd_vel I get:
r1 = Publisher with properties:
It works perfect, but for topic sound I get:
Failed to create a publisher with topic name /sound and type turtlebot3_msgs/Sound.
Can anyone give me any hint about why this behaviour?
Thank you very much in advance,
