About gazebo-Cosimulation problems

i running there commands

cd /home/user/src/GazeboPlugin/export

export SVGA_VGPU10=0

gazebo /home/user/worlds/Ur10BasicWithPlugin.world --verbose

have some problems!

my .so file

i have some question

how to build my Ur10BasicWithPlugin.world

how to solve the problem of terminal display

Answer 1

[Gaurav Bhosale]

Hi Bo,

I checked your Ur10BasicWithPlugin.world file.

Your world file contains dependecy on ROS plugin.

<plugin name='ros_control' filename='libgazebo_ros_control.so'>

<robotNamespace>/</robotNamespace>

</plugin>

Also, the message from Ubuntu terminal suggest that you need to initialize ROS.

So, I think, you might be missing ROS workflow.

Thanks.

Answer 2

[Gaurav Bhosale]

Hi bo,

From the world file, I can see, username is "zhangbo"

So, in that case, the correct command should be,

cd /home/zhangbo/src/GazeboPlugin/export

export SVGA_VGPU10=0

gazebo /home/zhangbo/worlds/Ur10BasicWithPlugin.world --verbose

Also, you can export plugin path as follow,

export GAZEBO_PLUGIN_PATH=${GAZEBO_PLUGIN_PATH}:/home/zhangbo/src/GazeboPlugin/export

Thanks

Hello!

Thank you very much for your reply!

As you suggested, I started from scratch.first,load ur arm and save as a .world file<newtest.world>.

source catkin_ws/devel/setup.bash
roslaunch ur_gazebo ur10.launch

Second.In the .world file source code add the following lines

<plugin name="GazeboPlugin" filename="lib/libGazeboCoSimPlugin.so">
    <portNumber>14581</portNumber>
</plugin>

Third.execute the following code.

cd /home/zhangbo/src/GazeboPlugin/export
export SVGA_VGPU10=0
gazebo /home/zhangbo/worlds/newtest.world --verbose
export GAZEBO_PLUGIN_PATH=${GAZEBO_PLUGIN_PATH}:/home/zhangbo/src/GazeboPlugin/export

But,it will be an error.

[FATAL] [1656398991.410763955]:You must call ros::init() before creating the first NodeHandle
[ERROR] [1656398991.412984740]:[registerPublisher] Failed to contact master at [:0]. Retrying...

What should I do?

Looking forward to your reply!

Thanks!

It's the same, how to solve it? Please let me know if you figure it out. Thank you.
