Hello

I have a question, how can I takeoff the drone using the motor_speed topic of ROS?. I am been trying but without success

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

Hi @danielrs975! It seems strange that you are not able to publish on the /command/motor_speed topic. However, the problem may be related to the version of Gazebo. Have you tried seeing in the issue tracker? Perhaps, the problem has already been solved by someone.

Hi! I am able to publish on the topic but I do not find the right values to make the drone takeoff

What do you mean by"the right values"? Have you seen that propellers move when you publish values on the topic?

Answer 5 · 2020-07-16T07:46:01.000Z

Yes the propellers move, for example I publish this angular velocities [1000, 1000, 1000, 1000] and the drone does not take off

Try to increase that value. I don't remember the value that allows the drone to take off. You can see the maximum propeller speeds in this file.
