Hi,
i have recently started with Gazebo and ROS hence I thought it is a good start doing the tutorial http://gazebosim.org/tutorials?cat=guided_i&tut=guided_i6
I have followed all the previous steps in the tutorial - everything worked well and I could also spin the laser by sending a message over the API I created.
The problem I now face is that Gazebo seems not to subscribe to the topic I start with ROS. Following the tutorial step by step (sourcing every step and maintaining the default directory structure )has not lead to success.
When running `rostopic info /my_velodyne/vel_cmd` I get the following:
Type: std_msgs/Float32
Publishers:
* /rostopic_13126_1485965572986 (http://ThinkPad-T460p:45658/)
Subscribers: None
So it seems that I publish a value which I can also read using `rostopic echo /my_velodyne/vel_cmd` but nothing (gazebo) is not listening to that value.
Since I usually work with catkin and ros I have no idea how to let gazebo subsribe to the given topic.
I am running ubuntu 16.04 and gazebo 7.0.0 and ros kinetic.
Thank you so much for your help! Any advice is appreciated!
