Hi, you can get the required packages from github using the branch 'kinetic': https://github.com/innokrobotics/innok_

2018-08-02 08:39:06 -0500 marked best answer How can I use custom python functions in other ROS packages?

Hi everybody,

I'm quite new to python programming in ROS (mainly used roscpp before). I generated a ROS package (let's call it "useful_python_functions") not providing any ROS node but several python functions. I wrote a python file (let's call it "utils.py") and saved it in useful_python_functions/src/utils.py.

Now I want to use the functions in other ROS packages. I added useful_python_functions as a dependency to the manifest.xml and then tried in my ROS node:

from useful_python_functions import utils

Running the node I get:

ImportError: cannot import name utils

As I saw here the src folder of useful_python_functions should be part of my PYTHONPATH by default.

How can I import the functions of utils.py in a ROS node from a different ROS package?

That worked for me. Thank you!

2016-03-03 02:21:34 -0500 commented question Howto release a package with system dependency ros-indigo-gazebo6-ros?

As a workaround I removed the run_depend gazebo_ros and gazebo_ros_plugins from package.xml. Users will have to install ros-indigo-gazebo6 and ros-indigo-gazebo6-plugins manually to be able to run the launch files.

2016-03-03 02:18:40 -0500 commented answer Jenkins build became unstable - what am I supposed to do?

As a workaround I removed the line roslaunch_add_file_check(launch) from the CMakeLists.txt. The build is stable now. But users will have to install ros-indigo-gazebo6 and ros-indigo-gazebo6-plugins manually to be able to run the launch files.

Ok, thank you. We were thinking about a cloud provider, too. But in the meantime I have a 64-bit system and I did the tests on this machine.

2016-02-11 15:49:39 -0500 commented question Howto release a package with system dependency ros-indigo-gazebo6-ros?

Thank you for this information. Can I add the rosdep keys for gazebo6 myself (e. g. with a patch) or is there any official support team I could ask for this feature?

2016-02-11 15:44:14 -0500 commented answer Jenkins build became unstable - what am I supposed to do?

Can I ignore the fact that the build is unstable until I found a way to include gazebo6 as run dep? Or could anything be harmed as long as the build is unstable?

2016-02-11 15:41:01 -0500 commented answer Jenkins build became unstable - what am I supposed to do?

In fact this is related with my other question: http://answers.ros.org/question/22633...

2016-02-11 15:39:48 -0500 commented answer Jenkins build became unstable - what am I supposed to do?

Thank you, now I see. The problem is exactly as you said: I removed run deps concerning gazebo from package.xml because this resolves in system dependencies of Gazebo2 in the resulting debian package. But I need Gazebo6 in order get a correctly running robot model with this package.

2016-02-11 11:24:18 -0500 asked a question Jenkins build became unstable - what am I supposed to do?

Hi,

I just released a new version of an existing package. Before the release I ran the prerelease test successfully.

Now I got an email from the ROS Buildfarm with the subject: "Jenkins build became unstable: [...]"

edit: Here is the link contained in the email: http://build.ros.org/job/Idev__innok_...

What am I supposed to do? Is this critical?

2016-02-11 10:54:29 -0500 asked a question Howto release a package with system dependency ros-indigo-gazebo6-ros?

Hi,

I have a ROS package with the run dependency gazebo_ros (specified in package.xml). When I release this package for Indigo the resulting debian package depends on ros-indigo-gazebo-ros.

Is it possible to make debian package depend on ros-indigo-gazebo6-ros?

Regards,

Sabrina

Could you provide your robot model? Maybe this helps to reproduce your issue.

2015-11-20 09:48:48 -0500 asked a question How to find out if prerelease test was successful?

Hi,

I have just ran prelease tests on my local machine with the commands generated on http://prerelease.ros.org .

prerelease.sh finished without any error prompt and the last output was

No test results in overlay workspace

Does it mean the test was successful? (In this case a final output like "Prelease Test finished successfully." would be more clearly ;) )

Or do I have to check for anything else?

Regards Sabrina

2015-11-11 01:42:11 -0500 asked a question Is there a 3rd-party buildfarm for pre-release tests?

Hi,

As the ROS buildfarm does not perform pre-release tests anymore (see http://answers.ros.org/question/21950... ), I tried to setup a virtual maschine with docker to run the tests locally. Unfortunately I have a 32-bit system and docker requires a 64-bit system. I'd like to avoid reinstalling my whole system just to run the tests.

So: Is there any 3rd-party buildfarm/cloud/server/host where I can run the tests on?

Regards, Sabrina

2015-10-22 10:00:07 -0500 marked best answer No more prerelease test on the buildfarm?

Hi,

I'd like to make a prerelease test for a package in Indigo on the buildfarm as described at http://wiki.ros.org/action/fullsearch...

Thus I go to http://prerelease.ros.org . Then I click on "Old Site" (on the top right) and choose "Indigo". I select my package, enter my email address and click on "Start Testing". But then the new page is loaded where the prerelease command is generated to run the test locally.

How can I run a prerelease test for an Indigo package on the buildfarm? Or can this only be done locally?

Thank you for any hint!

Regards, Sabrina

my package 'innok_heros_gazebo' fails to build in Jenkins with KeyError.

'innok_heros_description' is a run dependency of 'innok_heros_gazebo' and I added both packages to indigo/distribution.yaml without the release tag because I still have to perform the prerelease tests. Will the missing key 'innok_heros_descripion' appear in the key DB when the package is released?
