Hello,

I have run this tutorial (I am using ROS Hydro) wiki.ros.org/rosbridge_suite/Tutorials/RunningRosbridge on running rosbridge example.

When I started the HTML page, I noticed that all work expect publishing the /cmd/vel topic. I am getting this error message

[ERROR] [WallTime: 1397113517.026746] [Client 4] [id: advertise:/cmd_vel:1] advertise: __init__() got an unexpected keyword argument 'queue_size'

[ERROR] [WallTime: 1397113517.035466] [Client 4] [id: publish:/cmd_vel:2] publish: Cannot infer topic type for topic /cmd_vel as it is not yet advertised

Do you have any idea how to fix this issue?

I tested the same code on another Hydro machine and it worked, but on my machine with the same configuration, I had the error above.

Thank you in advance

Can you share the rosbridge package version and HTML code you tested?

Refer to the github issue in rosbridge_suite. It was because incompatibility in rospy between groovy and hydro. Groovy version of rosbridge_suite has been re-released and should not have this error as of now.

For my case, I just made a fresh installation of Hydro and everything worked fine after re-installation.

I am running into a similar problem. I am running Groovy on Ubuntu 12.04. I just apt-get upgraded my ros-groovy packages (to version 0.5.4-0precise-20140417-0429-+0000) and now code that used to work fine is suddenly broken. I am simply publishing an empty message on a topic from javascript using roslibjs (revision 6) and subscribing with a smach_ros.MonitorState. I get the error: "__init__() got an unexpected keyword argument 'queue_size'". Would love some ideas for how to fix this. Is it an issue with roslibjs or rosbridge? What can I change to make this work again?

I got same error in Ubuntu 12.04 and groovy. The solution is to use an overlay with an older version that works, the version 3.5 of the groovy-devel branch in github.

This are the instructions to get the old version. I assume you had created and sourced an overlay.

In a terminal..

roscd

cd ../src

git clone https://github.com/RobotWebTools/rosb... -b groovy-devel

cd rosbridge_suite

git reset --hard da51ab060ec74d7c026bf3f1dbb2bde76d55d0b9

cd ../..
