Ubuntu 18.04 with ROS Melodic and Gazebo 9 --- hovering example not working #25

Did you wait five seconds for the activation of the control algorithm? Here what is reported in the README.md file.
|

Yes I waited. The attached gazebo screenshot reports 1.31 minutes.

As I can read from the log, two are the main errors:
Now, I will take a look at the code, but these should be problems that I fixed a long time ago with the latest software release. |

I encountered the same problem running the hovering example. It was still okay when I tried that about 2 weeks ago (sorry that I forgot the exact time). I then reinstalled it today and it doesn't work now. The same error occurs when I tried running the original rotorS hovering example. This is my log as a reference

I fixed the issue with the I checked the installation instructions, and everything is fine. It might be an environmental problem, i.e, missing packages, Gazebo release, and so on. If you needed, as in #24, I can create a virtual machine with this configuration, i.e., ROS Melodic and Gazebo 9. |

@gsilano Unfortunately the most recent commit still doesn't work. If it's not because of this package, then the problem might come from the original repositories like rotors-simulator, mav_control_rw and voxblox, cause that's the only big difference I've made since the previous installation. A virtual machine with ROS Melodic and Gazebo 9 configuration is also of great help if available. I've also tried running a seperate |

Hi @gsilano @antbono , I did a fresh install of crazyS package in a new ros:melodic container docker but it still didn't work. It said the |

To understand the problem, I also created a fresh installation of ROS Melodic on Ubuntu 18.04. I think I discovered the problem: some Gazebo packages are missing in the default installation. In fact, following the instructions in the repository, I had the same problem illustrated by @antbono. So, I run the command mentioned below and everything was fine. $ sudo apt-get remove ros-melodic-gazebo* gazebo*
$ sudo sh -c 'echo "deb http://packages.osrfoundation.org/gazebo/ubuntu-stable `lsb_release -cs` main" > /etc/apt/sources.list.d/gazebo-stable.list'
$ wget http://packages.osrfoundation.org/gazebo.key -O - | sudo apt-key add -
$ sudo apt-get update
$ sudo apt-get install gazebo9 gazebo9-* ros-melodic-gazebo-*
$ sudo apt upgradePlease, try to use them and give me back. In the meantime, I will update the README.md file. |
I think this is a particular use case, so I cannot help you in defining the problem. |

@gsilano I followed the new readme and finally the simulation works! Thank you so much for your work :D |
I followed these instructions to have the simulation run on Gazebo 9 (along with Ubuntu 18.04 and ROS Melodic). However, now, when I run I was able to run |

Hi! Try to run the following steps, and then give me back.

Hi, thank you for your reply! After running Thanks again! |
I have just installed ubuntu 18.04 and followed the instructions reported in the readme file. All the steps run successfully and I can run the hovering example. The problem is that the crazyflie doesn't move at all. Nothing happens in the simulation. I tried to apply some forces to the crazyflie to see some changes in the rqt_plots but nothing happens. The rqt_graph at the moment of the simulation doesn't show any incoming connection to gazebo node.
Thank you for your attention
