2012-08-21 23:09:45 -0600 asked a question Gazebo unable to launch empty world

Hi~everyone

I installed ROS fuerte in Ubuntu 12.04 and I tried to launch the empty world

  roslaunch  gazebo_worlds empty_world.launch

I got the following error message:

  Error [Transport.cc:102] Unable to get topic namespaces in [50] tries.
  Error [Node.cc:68] No namespace found

/opt/ros/fuerte/stacks/simulator_gazebo/gazebo/scripts/gui: line 2: 5106 segmentation fault (core dumped) rospack find gazebo/gazebo/bin/gzclient -g rospack find gazebo/lib/libgazebo_ros_paths_plugin.so [gazebo_gui-3] process has died [pid 5099, exit code 139, cmd /opt/ros/fuerte/stacks/simulator_gazebo/gazebo/scripts/gui __name:=gazebo_gui __log:=/home/qxesqxes/.ros/log/326a199c-ec38-11e1-a2f0-c446195a3b7d/gazebo_gui-3.log]. log file: /home/qxesqxes/.ros/log/326a199c-ec38-11e1-a2f0-c446195a3b7d/gazebo_gui-3*.log

Your help would be much appreciated, thank you.

2012-03-26 18:03:25 -0600 asked a question Why rxgraph show partial information when selecting the combo box?

Hi~

I used rxgraph to see how gazebo works, and I found a weird thing.

It showed all topics connecting to the gazebo node when I didn't select any PATH combo box.

But when I selected the gazebo node of PATH combo box, it just showed little parts of all topics which connecting the gazebo node.

I am wondering why this happens.

Thanks in advance.
