I'm trying to implement a python script that dynamically reconfigures a ROS navigation parameter. However, I get an error saying 'No module named client' when I try to import the python API using 'import dynamic_reconfigure.client'. I checked 'rospack find' and the dynamic_reconfigure package is installed. I also directly installed dyanimc_reconfigure using the setup.py that I found in its package. Is there something I am missing?

Thanks for your help!

The NavFn global planner immediately recalculates its global path when it detects an obstacle in its current path (this obstacle is usually reported by the local planner). Is there a parameter that would delay the recalculation of this path? Since my obstacles are dynamic, I would want the global planner to wait 3-4 seconds before deciding to find a new path rather than do it immediately.

I am attempting to make a package called schunk_robots. However, I get the following error:

Does anyone know what this ivcon command is and why it's missing? Thanks a lot for your help!

PS: I am using ROS Fuerte on Ubuntu 12.04

I was just trying to run rviz to see if it worked or not.

Sorry for the late reply. I actually moved to a different computer and rviz is working correctly on this one. Not quite sure what the issue was on previous computer but it works now!

I am currently using ROS Fuerte on Ubuntu 12.04LTS. I know there have been several forum topics mentioning the same problem I had but none of them seem to offer me the right solution, so here I am asking the question again. After having created a workspace in ROS and sourcing the setup.bash file, I run 'rosdep install rviz'. Once all the dependencies have been installed, I compile the package using 'rosmake rviz'. The package builds successfully. I then run 'rosrun rviz rviz' and get the following results (ignore the color coding):

sinhau@ubuntu:~/tf_tutorials$ rosrun rviz rviz

[ INFO] [1350587343.349569680]: rviz revision number 1.8.14

[ INFO] [1350587343.349747565]: compiles against OGRE version 1.7.3 (Cthugha)

[ INFO] [1350587343.378668970]: Loading general config from [/home/sinhau/.rviz/config]

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

Segmentation fault (core dumped)

I looked into the '.rviz' folder and found it to be empty. So I have no idea what the problem is. Some of the suggested solutions in other forums were to change the variable OGRE_RTT_MODE to either Copy,FBO, or PBuffer. I tried all of them using export OGRE_RTT_MODE=________ and reran rviz using 'rosrun rviz rviz'. The results were still the same. If anybody has an idea as to what's going on, sharing it would be much appreciated.

Thanks!
