Hi is there any tutorial or website where i can find details about "types of joints" to design a robot model in rviz and how they work and coded ???...........i have already searched urdf tutorials i cant find it there

Hi all, I want to run the simulation http://www.ros.org/wiki/urdf/Tutorials/Building%20a%20Visual%20Robot%20Model%20with%20URDF%20from%20Scratch

but as soon as i run command

roslaunch urdf_tutorial display.launch model:=01-myfirst.urdf

it gives me errors as listed below

process[rviz-3]: started with pid [8013]

Config file '/home/sanket/.rviz/config' could not be opened for reading.

Xlib: extension "GLX" missing on display ":0.0".

log file: /home/sanket/.ros/log/5e4ebc6c-c928-11e1-950f-848f69c0fd9c/rviz-3*.log

i don't know whether my rviz is missing some files or is it related to system requirements of my laptop

HI ALL , as i run command

rosrun rviz rviz

rviz screen opens and closes immediately and i get following code

Config file '/home/sanket/.rviz/config' could not be opened for reading.

Segmentation fault (core dumped)

i have created a robot model for rviz in urdf format.....how can i use this model on gazebo...i mean what changes do i have to make???

thanks..it solved my problem.

Hi,I'm trying to run rviz over distributed system using roslaunch file.

Roslaunch file is as follows :-

<launch>

<include file="$(find urdf_tutorial)/display.launch">
<arg name="model" value="/home/sanket/ros_workspace/humanoid.urdf" />
</include>

<machine name="primary" address="172.16.2.159" user="san" default="false"/>

<machine name="secondary" address="172.16.3.182" user="san1" default="true" password="ai"/>



<node name="modelvisualisation" pkg="rviz" type="rviz" output="screen" args="-d /home/sanket/ros_workspace/h1.vcg" />

</launch>

when i run above launch file i get following errors :-

rosserial worked fine on fuerte in my case, anyways thanks.

Hi Guys,

I was trying to follow the tutorials under rosserial_arduino from this link:

http://www.ros.org/wiki/rosserial_arduino/Tutorials/Hello%20World

But I have gotten an error message for this command:

rosrun rosserial_python serial_node.py /dev/ttyUSB0

I got following error message:

Traceback (most recent call last):
  File "/home/sanket/ros_workspace/rosserial/rosserial_python/nodes/serial_node.py", line 38, in <module>
import roslib; roslib.load_manifest("rosserial_python")
  File "/opt/ros/fuerte/lib/python2.7/dist-packages/roslib/__init__.py", line 50, in <module>
from roslib.launcher import load_manifest
  File "/opt/ros/fuerte/lib/python2.7/dist-packages/roslib/launcher.py", line 42, in <module>
import rospkg
ImportError: No module named rospkg

Thanks in advance.

have u installed the requirements for gazebo???http://gazebosim.org/wiki/requirements

i think your gazebo is not completely integrated with ogre...you have to install gazebo with source pkg as in debian package it does not completely integrates with ogre...other things u can do is that to check whether u have setup environment variables correctly.
