Thanks for opening your first issue here! Make sure that no other issues on the same topic have already been opened!

This seems to be an old problem. Have you tried to see if there are similar problems like yours in the issue tracker? However, first of all, I would see if everything works by executing a few simple commands, e.g., rqt to have a node graph and rostopic list to see the list of available topics. Then, give me back with the results and I will try to help you in some way.

Thank a lot! My installation environment is Ubuntu 16.04 with ROS Kinetic and Gazebo 7
When executing roslaunch bebop_simulator bebop_without_controller.launch, it shows that

when executing rqt_graph, it shows that

when executing rostopic list, it shows that

my problem is, when executing rostopic pub /gazebo/command/motor_speed mav_msgs/Actuators '{angular_velocities: [1000, 1000, 1000, 1000]}' , it occurs error

Ye, I got it. As you can see, there is something wrong with the Gazebo and/or ROS environment. For this reason, the propeller angular velocities command cannot be sent. I suggest taking a look at previous issues. For example, this one: #23

Oh, it seems a old question. Anyway, Thanks for your guidance. I will continue to pay attention to this issue. Besides, I found I can control the UAV by using the waypoints.txt, it's enough for me temporary.
