Description
Good day, I installed CrazyS for ubuntu 18.04, ROS melodic and Gazebo9. When running the crazyflie2 hovering example, I could not get it to run.
I used the example command given in the readme:
roslaunch rotors_gazebo crazyflie2_hovering_example.launchThis was the error displayed for me.
