Hello!

I create a Phyton project within the ar_pose package. I tried to import roslib to my Phyton program with

import roslib; roslib.load_manifest('ar_pose')

,but get the answer that he could not found the module roslib.

Is roslib a own package which I have to download?

Thanks!

(ROS electric)

Hello!

I have Ubuntu 10.04 and installes ROS electric.

I am trying to make $ rosmake turtlesim (Tutorials - Understanding ROS Nodes), but get following error message:

rosmake Packages requested are: ['turtlesim']
rosmake Logging to directory/home/janina/.ros/rosmake/rosmake_output-20120802-160904 rosmake Expanded args ['turtlesim'] to: []
rosmake WARNING: The following args could not be parsed as stacks or packages: ['turtlesim'] rosmake ERROR: No arguments could be parsed into valid package or stack names.

How can I install the turtlesim package? I think it,s missing?

I get following error message when I like to run the demo with roslaunch ar_pose demo_single.launch

(Link: http://www.ros.org/wiki/ar_pose):

The program 'rviz' received an X Window System error. This probably reflects a bug in the program. The error was 'BadDrawable (invalid Pixmap or Window parameter)'.

To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)

What can I do?

Are there anywhere finished standard markers for the ar_toolkit to download and to print?

I like to install the CCNY Computer Vision Stack.

(Link: http://www.ros.org/wiki/ccny_vision#Installing)

But I have no folder ros/stacks, so where should I install the stack? I only have a folder "ros-workspace" in my home directory. Should i create there an "stacks" folder?

I am new at this topic, so I hope you can help me.

How can I use the ARtoolkit library with rviz?

(Ubuntu 10.04, ROS electric)

How can I install the ARtoolkit library? (Ubuntu 10.04, ROS electric)

Can I install/start rviz, when I only have installed ROS base (Ubunto 10.04, electric)?

Hi.

I am using the ar_kinect package to realize ar_markers and get the their coordinates back.

I like to create a map which shows all objects in the room which are marked with the ar_markers.

I think that the coordinates from the markers which I get back are coordinates from the corner of the marker.

Am I right that I have to fix the markers all around the object? How can I create and save an image from the realized objects?

Thanks for help!

I have installed ROS electric (Ubuntu 10.04).

I get this error message when I like to start rviz with rosrun rviz rviz:

**Segmentation fault**

I tried export OGRE_RTT_MODE=Copy (also PBuffer, or FBO), but it does not work.

Does anybody know an other solution for this problem?

Thanks for help!
