Hi all,

Pretty quick question: can meshes be used and rendered in urdf files for the moveit_setup_assistant? I ask because currently, when I try to load a urdf with a reference to a .stl file, I get the following error:

[rospack] Error: no package/stack given And mesh files don't load. Does anyone know why this is?

EDIT: I'm actually wondering - is this just a limitation of rviz? Are there certain ways one would have to have their urdf formatted to make all the meshes appear properly? Will only certain filetypes render?

Hi all,

Working on Ubuntu 12.04, ROS Hydro

Recently, I decided I wanted to make changes to robot_state_publisher. In order to do this, I downloaded the source code and made changes, added its location to my ROS_PACKAGE_PATH (I can roscd to it just fine), and apt-get purge'd the binary. Unfortunately, now when I try to rosmake a package that depends on robot_state_publisher, I get the error I've included below. I've tried deleting the ~/.ros folder's contents (and re-initializing) and make clean-ing. Neither fix this problem.

I'm totally stumped. Does anyone have any ideas on this? It shouldn't be looking for that .pc file because it should no longer be looking for the binary, but I don't know what to delete or add to make it look in source.

Hi all,

I'm very stumped regarding our migrating of a plugin from electric up to groovy. But, the problem seems to not be within our code, but within the ROS code. Either that, or we're no longer including something correctly.

There are two errors: First, in our init.cpp, we attempt to include rviz/plugin/type_registry.h , and there's: Fatal Error: rviz/plugin/type_registry.h: No such file or directory does this file no longer exist? Has it been replaced by something?

Second, in /opt/ros/groovy/include/rviz/properties/property.h there's: fatal error: QObject: No such file or directory.

But I believe QT is installed. Are we missing a dependency?

Hi all,

First of all, Ubuntu 64 bit 12.04 Hydro.

I'm trying to make an RViz plugin with animations. To get started, I modified the code from the tutorial:

http://docs.ros.org/hydro/api/rviz_pl...

If I try to do some sort of "animation" though, by creating a marker, sleeping, updating the marker, sleeping, etc., this doesn't cause anything to render. I'm guessing that this is because I'm making the entire RViz system sleep, so it can't update.

In order to get around this, for each incoming message, I fire off a thread tahtthen is in charge of painting for this thread. Unfortunately, this has led to numerous graphical glitches - and after the first one, it fails to paint for subsequent loops.

So much is abstracted away from the user in these plugins (it's actually extremely frustrating!) that I really do not have a good grasp on how the painting occurs. And there is little to no documentation on these things.

I'm looking for an explanation as to how the painting actually occurs, and possibly a suggestion on how to do animations correctly?

Hi all,

Before I upgraded today, the moveit_setup_assistant had no problem loading this file, although it wasn't rendering any of the imported meshes (I was trying to figure that out):

https://github.com/bellenss/youbot-ros-pkg-kdl/blob/master/robots/youbot.urdf

After I did an upgrade (sudo apt-get upgrade) today, though, when I try to upload this file, I get the following error:

[rospack] Error: no package/stack given
[librospack]: error while executing command

All of the joint types listed are of the standard type. Is this a bug? Or does anyone know what the cause is?

Hey all,

I'm a little stumped on this one. Ubuntu 12.04, ROS groovy, building with rosbuild (porting legacy packages).

I have a package that we've developed that shows up 100% perfectly using a roscd or a rospack find. The problem is, when doing a roslaunch or a rosmake, I get the following errors:

[ rosmake ] rosmake starting...
[ rosmake ] No package or stack specified. And current directory 'track_obj' is not a package name or stack name. [ rosmake ] Packages requested are: []
[ rosmake ] Logging to directory /home/youbot/.ros/rosmake/rosmake_output-20130715-141430 [ rosmake ] Expanded args [] to: []
[ rosmake ] ERROR: No arguments could be parsed into valid package or stack names.

It doesn't matter if I put the package name there, or move to the directory and give it "." it always fails.

My $ROS_PACKAGE_PATH both includes a parent folder and now the actual package folder for good measure.

Why might rospack find work, but rosmake fail?

We're working on some object tracking stuff using OpenCV and so we have some code that works as a standalone C++ project, and also has a ROS wrapper. I'm not sure that part's relevant.

If there are any files I can provide to help diagnose this problem, let me know.

Hi all,

I'm trying to do the tutorials, but I'm running into lots of trouble with using anything rqt related. For example, in the tutorial on the rqt_console (http://www.ros.org/wiki/ROS/Tutorials/UsingRqtconsoleRoslaunch), I try rosrun rqt_console rqt_console and get the output below. I noticed I"m having a permission denied error, but I'm not sure how to get around that. Does anybody have any suggestions?

Hi,

I'm following the install instructions for kinect located here: http://www.ros.org/wiki/ni#Setup_and_...

But when I do, I get the following error at this step:

/opt/ros/cturtle/ros/core/roscpp$ rosinstall ~/ni /opt/ros/unstable 'http://www.ros.org/wiki/ni?action=AttachFile&do=get&target=ni.rosinstall'

rosinstall: command not found

I installed cturtle on linux 10.10 using the "base" installation, and ran the given command to set my environment. Most of ros functionality seems to be working.

Does anybody know what the problem might be?

Thank you for your time,

Andy

Hi all,

I'm trying to clone the following git repository:

http://robotics.ccny.cuny.edu/git/ccny-ros-pkg/ccny_vision.git

But the cloning is failing. Furthermore, when I try to access anything related tot he robotics.ccny.cuny.edu base url, I'm redirected through wayback machine (with no valid snapshots in June). It seems like this repository is dead. Does anyone know where the new one might be located, if there's one at all? Is there any other way to get this package?

Hi,

I'm trying to upgrade a system from electric to groovy. Unfortunately, I'm getting stuck since the codebase uses btQuaternion.

The short version though is, I can't find the migration script mentioned here: http://ros.org/wiki/geometry/bullet_migration

My tf folder has no scripts with that name. All I have are: static_transform_publisher tf_change_notifier tf_echo tf_empty_listener tf_monitor

What happened to the conversion script? Was it removed?

Hi Mortonjt, I tried installing pcl1.7 for ROS but couldn't find it in there. It's not in the default install, I don't think, since when I just built pcl from source, I had to configure the CMakeLists. Is there any other way to get it from the ppa, or am I stuck building from source?

Hi all,

I'm trying to figure out where the pcl gpu headers are put when installed via ros. I am running ros-groovy and have pcl 1.6 installed.

However, my pcl-1.6 folder only includes the following:

channel_properties.h  io                      point_types_conversion.h
cloud_properties.h    kdtree                  point_types.h
common                keypoints               range_image
compression           octree                  registration
console               pcl_base.h              ros
correspondence.h      pcl_config.h            sample_consensus
exceptions.h          pcl_exports.h           search
features              pcl_macros.h            segmentation
filters               pcl_tests.h             surface
for_each_type.h       point_cloud.h           TextureMesh.h
geometry              point_representation.h  tracking
impl                  point_traits.h          visualization

Where can I find the gpu folder? Is it not installed by default? If not, where do I get it from?

Wow, yeah, I really messed that one up, huh? Thanks!
