Failed to Launch Gazebo Simulation Environment

Hi all,

I am following this post to perform co-simulation between Simulink and Gazebo

https://www.mathworks.com/help/robotics/ug/perform-co-simulation-between-simulink-and-gazebo.html

I am using Virtual Machine to launch Gazebo Simulation Environment

After I open a terminal in the VM, run the following commands to launch the Gazebo simulator.

cd /home/user/src/GazeboPlugin/export

export SVGA_VGPU10=0

gazebo ../world/multiSensorPluginTest.world --verbose

Then I got the following error:

Unable to parse model.config for model[http://gazebosim.org/models/bin_4_dropping_task

I checked this error in many website sources but still not figured out.

I'd highly appreciate if you can give me some insights to fix this issue.

Thank you so much!

same question, and then i used "Gazebo subscribe block" to subscribe the topic that i published in gazebo(Ubuntu), the "block" can not get any topic from gazebo, although i could see all the topic in ubuntu "gz topic -l"

Hi Van,

The shipped VM contains older Gazebo version and RAM is limited to 2GB.

Can you please try following two things,

1] Upgrade Gazebo version to latest ( mostly 9.16 )

sudo apt-get install gazebo=9.16

2] Change RAM to 4GB from VM settings.

Please let me know, if you still face same issue.

Thanks.

Thanks Gaurav,

When I use sudo, it requires the password. Do you know which is password for the Ubuntu? As I follow the steps from here

Thanks Gaurav,

I just tried sudo apt-get install gazebo=9.16, but it shows

E: Unable to locate package gazebo

Do you know why? Thank you.
