Thanks for your help Galdeano. I am using a Baxter research robot IR range finder from Rethink Robotics inc just so you know. I think those links will help me figure out. I'll mark your answer as the answer.

Thanks Galdeano. When I write the code then, where should I put the declaration? It's not shown in the tutorial here:http://wiki.ros.org/ROS/Tutorials/WritingPublisherSubscriber%28python%29. Would that work in Python? Is there any command line action that would change the max_range in the robot?

Hi everyone, ROS noob here. Do any of you know how to set the max range on ir range finder sensor shown on this:http://docs.ros.org/api/sensor_msgs/html/msg/Range.html? For some reasons, the IR Range Finder sensor that I run whenever I print the data would give out the max_range of 0.4m and min_range of 0m. Is there a way to change that default? Thanks.

ps: I haven't wrote the code yet (it is going to be in Python). I was getting the IR Range data of the Baxter robot using the Rostopic echo /robot/range/right_arm_range command. It would then print out the result with max_range 0.4m. Would that mean that is the robot's IR reader limitation then?

Awesome. Thanks! and I just realized that it is mentioned on top of this page:wiki.ros.org/rviz/Troubleshooting and found out that my laptop has Intel Mobile 4 Graphics Controller. so I am definitely will put it in my .bashrc.

Hi Patrick, thanks for responding. That seems to work for launching pr2 demo.launch now. However, every time I close Rviz that error message would show and have to use ctrl c to get out of it from the terminal. Do you think it's a good idea to put LIBGL_ALWAYS_SOFTWARE=1 in .bashrc? Thanks. --willi

Hi everyone, I am a newbie and was trying to follow the tutorial from here:moveit.ros.org/wiki/PR2/Rviz_Plugin/Quick_Start and when I tried launching roslaunch pr2_moveit_config demo.launch, I would get this message below:

All is well! Everyone is happy! You can start planning now!

[rviz_cehd_1050011_7612_1188156060-6] process has died [pid 7687, exit code -11, cmd /opt/ros/hydro/lib/rviz/rviz -d /opt/ros/hydro/share/pr2_moveit_config/launch/moveit.rviz __name:=rviz_cehd_1050011_7612_1188156060 __log:=/home/willi/.ros/log/50fcfb64-52ca-11e3-b7fb-0024e8bf7cc6/rviz_cehd_1050011_7612_1188156060-6.log]. log file: /home/willi/.ros/log/50fcfb64-52ca-11e3-b7fb-0024e8bf7cc6/rviz_cehd_1050011_7612_1188156060-6*.log

I searched around and it is a similar message but not exactly the same on this one://answers.ros.org/question/75769/ros-moveit-pr2-demo-launch-fails/. It fails at the end after saying all is well etc.

I just reinstall Ubuntu 12.0.4 64 bit because I thought my previous Ubuntu 12.0.4 32 bit is not working (always getting the same error 11) so I just freshly installed ROS Hydro, MoveIt and PR2 full and it is still failing and it's only a tutorial.

Can anyone give me an insights on what to do next? Thanks a lot.
