Hi!

I'm having a problem with roslaunch rqt_gui rqt_gui. When I launch this command in terminal, only upper bar appears, then it disappears and appears again in different place, but the rqt_gui itself does not launch eventually. I believe it's connected to some plugin I wrote, though there are no error msgs in terminal. Is it possible to somehow run rqt_gui with requested perspective? I'd like to run rqt_gui with default perspective and try adding my plugin again, to see if it is the cause of my problem - now I'm not able to do anything in rqt.

Thanks in advance,

Hi!

I'd like to use skeleton_markers for displaying skeleton tracked by kinect in RViz on Ros fuerte, Ubuntu 12.04 x86. And I'm having problems.

I downloaded the skeleton_marker from svn, as suggested in ROS tutorial for skeleton-marker and I placed it in my ~/fuerte_wrkspc/sandbox (as suggested in tutorials for beginners). Now, when I try to

rosmake skeleton_markers

it gives an error :

[rosmake-0] Starting >>> skeleton_markers [ make ]

I'm in the very begining of my adventure with ROS, so maybe I don't see some obvious steps that should be performed. I'll be gratefull for your help!

Hi there!

I just discovered rqt which seems to be super cool thing :) Is there a way to save configuration? So next time I just load all the plugins I've chosen previosly? (Like loading config in RViz)

Cheers, da-na

Hi there!

I'd like to add robot_description to parameter server and frankly speaking, after reading the tutorial about making urdf, I still have no idea, how to do that.

In my launch file I did:

<launch>

  <node pkg="robot_state_publisher" type="state_publisher" name="robot_state_publisher">
    **<remap from="robot_description" to="$(find museumGuide)/urdf_model/peoplebot.xml" />**

    <remap from="joint_state" to="joint_state"/>
    <param name="publish_frequency" type="double" value="15.0"/>
    <param name="tf_prefix" type="string" value=""/>
  </node>

</launch>

But apparently this line remap from="robot_description" to="$(find museumGuide)/urdf_model/peoplebot.xml" / is wrong, as I get error:

remap to [/home/peoplebot/fuerte_wrkspc/sandbox/museumGuide/urdf_model/peoplebot.xml] is not a valid ROS name

I'd be gratefull for your help! Thanks in advance,

Hi!

Is it possible to publish negative values via rostopic pub ? I tried

rostopic pub -1 /my_point geometry_msgs/Point 1 2 3

with no problem, but when I try

rostopic pub -1 /my_point geometry_msgs/Point 1 -2 3

it says an error:

Usage: rostopic pub /topic type [args...]

rostopic: error: no such option: -2

Is it anyhow possible to publish negative values from terminal?

Hello! For some reasons when I use ssh connection autocompletion with ros-commands doesn't work. On the original computer tab completion works, but when I connect to it via ssh I cannot use tab completion :(

I have "source /opt/ros/fuerte/setup.bash" in my .bashrc

I get the following error, after writing roscd [+tab]

roscd terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid

Anyone had the same problem?
