i wrote a c++ node that publish std_msgs::Float64 to a topic where my gazebo is connected.
so the connection is done, but i have a problem cause gazebo didn't receive the message sent.
i'm trying : rostopic echo /pkg_robot/joint1_position_controller/command
to message published, and i have this warning :
WARNING: no messages received and simulated time is active.
Is /clock being published?
if you could help i would be so thankful.
