Hello Azeey, Thank you, |

Unfortunately, I don't have enough cycles to diagnose the problem that way. I noticed from the logs you have built Gazebo from source. Have you tried the other examples in the |
|
Yes, I built Gazebo from source (5 hrs job!) because a had found a post suggesting that it might solve the problem. Unfortunately, noting changes... The problem remains the same: topic /cmd_vel doesn't get published! I tried to run rolling_shapes.sdf and it works fine! I would like to show you the following... if you do this: the TCP ports are open but no activity seems to be going on through these ports
this is the only TCP activity in the VM... and the above ports are not involved! Does this mean anything to you? |

I wonder if you have multiple versions of |

Hi Azeey, |
|
That looks okay to me. Can you share the |
|
I'm starting to think that Gazebo is not able to run in a VirtualBox VM. Do you believe this could be the origin of the problem? Here is my .sdf file: building_robot.txt (I just changed the extendion to .txt to be able to load the file) Thx! |
|
Yeah, I'm suspecting the same thing. It's surprising though since usually the problem is 3D acceleration, not gz-transport communication. I tried your file and it works fine for me locally. I'm curious why you're using a VM. If your host is Linux Mint, you should be able to use docker. Have you considered that? |
|
Hello Azeey, Sorry for all the troubles and thank you very very much for your support. |
|
I suspect there's some configuration that needs to be set on the VM or host machine to allow gz-transport to work. I've seen others use VirtualBox with Gazebo, but this is the first time I'm hearing of such problems, so I don't want to conclude Gazebo doesn't work on VirtualBox. That being said, I'm glad to hear it's working for you on the host machine. I'll go ahead and close this issue. |
