So I just experimented cloning the ament_copyright package to my workspace, added my proprietary license to ament_copyri

Yes I understood that, let me rephrase, I like having the information on the files thus I like the idea of having the te

Extending the package seems like a very good option for this use case, I'll give it a try and report on my findings.

That's definitely an option, thinking about it licensing is extremely relevant for open source software, maybe not so mu

I'm exploring ROS2, and I'm currently looking into unit testing.

I'm running the following commands,

colcon test
colcon test-result --verbose

I'm always getting a warning for a missing license:

test/test_something.py: copyright=My Company (2020), license=<unknown>

This is the header for my test_something.py file:

# Copyright 2020 My Company
# Proprietary License

Whats the proper text to include in the header for the warning to go away, for a Proprietary Software License? I've taken a look at the ament_copyright documentation but I didn't find an answer to my question.

Whats the proper way to use a proprietary software license according to ament_copyright? I'm exploring ROS2, and I'm cur

I am trying to compile a ROS node using OpenFOAM C++ libraries. OpenFOAM uses Wmake while ROS uses Cmake. How can I modify my CMakeLists.txt file so that the Cmake can:

1. Find the OpenFOAM .H files recursively installed in /opt/openfoam211/src
2. Find the pre-compiled OpenFOAM libraries (.so) also in /opt/openfoam211/platforms/linuxGccDPOpt/lib

I tried making a small Cmake script to recursively add all directories containing .H files using include_directories(). It finds all the .H files but I get the following error:

c++: error trying to exec 'usr/lib/gcc/i686-linux-gnu/4.6/cc1plus': execv: Argument list too long

I'm guessing I'm getting all the .H files making an enormous argument list.

I used target_link_libraries() for linking the libraries but I have no idea if it works since it never reaches that stage.

I'm using ROS fuerte on an Ubuntu 12.04 VM on Mac OS X Lion.

Thanks in advance!!!

Hi everyone! I noticed that swistrack appears as one of the many stacks that uses roscpp however there's no wiki page, thus I have no idea where to download the source from.

Does anyone know where swistrack for ROS is hosted?

I am running Mac OS X Lion 10.7.3 and ROS electric, I followed the tutorial on how to install ROS using Homebrew. Any suggestions? Thanks in advance!

Hi everyone!

I've just noticed that my rviz is not showing the Tools bar, this is the bar on the top that has buttons for moving the camera, selecting, setting goals, etc.

I installed ros electric using the homebrew tutorial. My Mac OS X version is 10.7.3. Rviz compiled just fine, though I do get some warnings at the rviz startup.

Does anyone else have this problem? Any ideas on how to get the Tools bar?

Hi everyone!

I'm extracting a cylinder using PCL and the Kinect as shown in this tutorial:

http://pointclouds.org/documentation/tutorials/cylinder_segmentation.php#cylinder-segmentation

One of the characteristics of the cylinder that the algorithm provides me with is its axis. In order to show it in rviz as a Marker however I need to convert this Vector3<x, y, z> into a Quaternion<x, y, z, w>.

I am aware that both things cannot hold the same information, I am trying to calculate the look at quaternion given to me by the vector that represents the axis of the cylinder that provides me a direction and not a rotation. How do I do that?

Thanks!

Hi!

I'm trying to compile rviz on Mac OS X Lion 10.7.3 but I'm having some problems with ogre_tools and wxWidgets. Apparently ogre_tools is not finding wxWidgets. Here's the output:

I have already done rosdep install rviz with the following output: "All required rosdeps installed successfully".

On the tutorial it is said that wxWidgets should be installed by rosdep, "This installer is downloaded and run automatically for you by rosdep..." from http://www.ros.org/wiki/electric/Installation/OSX/Homebrew

Hi everyone!

I've have allays used the robot footprint to view my robot in rviz. My robot does not have any moving parts, however I would like to see its 3D model in rviz instead of its footprint.

I'm using an erratic, and I was going through the urdf files and for most of it across the ROS wiki it strikes me that the urdf files are usually used for Gazebo simulations.

So how can I use a robot urdf file to simply view the real robot in rviz?

Also, instead of using static tf transforms for my tf tree can I use the urdf model containing the sensors to publish that information, even if there are not moving joints? How do I do that?

I apologize if this is a very simple question however I was going through the wiki and I could not figure out and started to get a bit confused!

Thanks in advance!

Hi everyone!

So here's my problem...

I have 6 netbooks with Ubuntu 10.04 and ROS c-turtle. When I first installed everything I did so on the first netbook and cloned the image to the other 5.

Now I want to update ROS to diamondback, I could do the update one by one, but I'm guessing there is a faster way! What options do I have to update/install ROS and manage the robot's ROS stacks without having to work on the netbooks one by one?

Thanks for the help in advance,

I have a swissranger SR4000 3D camera that I mounted on an erratic and I would like to use it for navigation instead of a laser.

I changed the navigation configuration files to input a point cloud instead of a laser scan, however since I'm using amcl for localization I kind of need a laser scan!

So I checked the turtlebot stack to see how you guys do it with the kinect and I found out you have a nodelet that turns a point cloud into a virtual laser scan.

Now my problem is the kinect driver is a nodelet, and the swissranger driver node is not. I am aware of what nodelets are, however I have never looked into them.

In order to use the pointcloud_to_laserscan nodelet should I create a nodelet version of the swissranger_camera node? Or can I just run the swissranger_camera node as I normally would and run the pointcloud_to_laserscan nodelet on its own?
