8 years ago Hello,
Just a quick acknowledge that I saw this and going to look into it, I can't make it before tomorrow though. It will probably be something gone wrong in Step... could you send the output of all steps please?

8 years ago Hello,
The service is obviously not up and running, as you pointed out.
Can you send a rosparam list after Step 1 and both a rosparam list and a rosservice list after Step 2?
Make sure both steps are started in separate terminals (which I guess you did) and are not aborted.
Do you have a roscore running in a separate terminal in the background somewhere?

7 years ago Hello Jenny,
thank you for your reply. Here is the output of the commands:
rosparam listafter step 1
rosparam listafter step 2
rosservice listafter step2
I execute every step in a new terminal and they keep running. I tried both, running a fresh roscore before step 1 (after executing killall roscore) and executing the steps without a previously running roscore. I did not find any differences in terms of the erroneous behaviour.

7 years ago Hi,
sorry for taking so long to reply. I've been crazy busy in the last days. I've had to set up a test system again as I haven't been using this code lately. I could reproduce your error, a new mistake must have snug into the code some time in one of the last pushes: The default of load_world_plugins in jaco_on_table/jaco_on_table_gazebo_controlled.launch was set to false :( I don't know why I did that, I must have been testing something and then forgotten to set it back to true.
I've pushed the update, can you try it again?

7 years ago Hello Jenny,
thank you very much for investigating. This solves my problem. Anyway I'm not able to see any commit on jaco_on_table_gazebo_controlled.launch. Are you sure you pushed the commit?
Thank you once again,
Odysseus

7 years ago Hi,
Huh, I thought I did! Will check when I get home. You can change it yourself meanwhile, just set the default to true :)

6 years ago Hi. I am working on a Universal Robot but I get the same error at the same step [ERROR] [1479977436.039658131]: Failed to call service /gazebo_objects/get_info, success flag: 0
Where should I add load_world_plugins
I am still new to ROS
Thank you

6 years ago From some launch file, you must launch gazebo, like this
<include file="$(find gazebo_ros)/launch/empty_world.launch">
<arg name="world_name" value="$(arg gazebo_world_file)"/>
<arg name="paused" value="false"/>
<arg name="verbose" value="false"/>
<arg name="use_sim_time" value="true"/>
<arg name="gui" value="true"/>
<arg name="headless" value="false"/>
<arg name="debug" value="false"/>
<arg name="extra_gazebo_args" value="-s libgazebo_world_plugin_loader.so"/>
</include> You must have the extra line extra_gazebo_args
Hello,
I'm trying to tinker around with the fake_object_recognition and tried to execute the tutorial . Until step 3 (spawning the cube) everything works perfectly. At step 4 I get this error:
rosuser@computer ~/test_jaco $ rosrun gazebo_state_plugins gazebo_request_object_info cube1 [ INFO] [1479977436.038761419]: Got objects topic name: </gazebo_objects/get_info> [ERROR] [1479977436.039658131]: Failed to call service /gazebo_objects/get_info, success flag: 0

I'm running ROS Jade with Gazebo 5.3.0 on Mint based on Ubuntu 14.04, I checked out convenience-pkgs, gazebo-pkgs, gazebo-pkgs, jaco-arm-pkgs, joint-control-pkgs and the dependencies from the wiki. Compilation works fine and I'm able to start the gazebo simulation with the robot. Therefore I assume that something is wrong with loading the world plugin or the later loaded plugins that offer the get_info service...
Since I'm quite new to Gazebo and it's plugin system a couldn't figure out until now, where the chain is broken. Any suggestions?
