I have a python node that takes xbox 360 controller inputs and publishes to cmd_vel topic. This node works fine when the ROS master is running on my laptop.
The robot i've built has a raspberry pi on it which runs the ROS master, and I use my laptop to run RVIZ and the node mentioned above, communicating with the ROS master via wifi. The problem is that i cant run the node on my laptop with the ros master being on the pi.
The comms between the two computers works fine, installed nodes on either work fine. I.e RVIS runs happily on the laptop and i can rostopic echo stuff. But when i try and run the node that i made in the catkin_ws i get something along the lines of the following -
Unable to register with master node [http://192.168.0.101:11311/]: master may not be running yet. Will keep trying.
Every time i reboot my machine i need to source the bash file in devel or whichever one it is (ROS reminds me of a messy university dorm room sometimes), I think this is the problem, as if i try and run a preinstalled node like the teleop key, it can't talk to the ros master. But then if i source ~/.bashrc (which is done by default in every new terminal) it can't find my package, which has my joystick node in it.
My question is, how do i install this package onto my system, much in the same way apt-get does when you install a ros package that way? A google search makes me think rosinstall might be what im after, but trying to find meaningful documentation is like trying to boil water in a chocolate tea pot. As per with anything ROS related.
Cheers in advance.

New linux user account can't access ROS tooling
Hi there,
I installed ROS on my PC using my normal user account. I can use all ROS tooling such as catkin_make or roslaunch on this account.
I just created a new user using 'adduser, however this user can't access any of the ROS tooling.
I added the /opt/ros/indigo/bin path to the user's PATH, which helps the user locate the executeables but they still fail when running. It feels like I'm doing something fundamentally wrong with adding this new user, am I missing something?

"ImportError no module named" error when package with msg also has setup.py and installed
I have a package with a foo.msg and a python module my_package/src/my_package/bar.py that works fine in the devel space- I can import the msg or alternatively import the python module just fine. But after running catkin_make install the I get an import error:
catkin_make install
source devel/setup.bash
python
>>>> from mypackage.msg import Foo
>>>>>>>> # (no error output, worked fine)
source install/setup.bash
>>>> from mypackage.msg import Foo
Traceback (most recent call last):
File "", line 1, in
Import Error: No module named my_package.msg
I commented out the `catkin_python_setup` from the CMakeLists.txt and rebuilt (`rm -rf build devel install` followed by `source /opt/ros/jade/setup.bash` seems safest which maybe ought to become the topic of another question...), then the import works fine.
One thing I notice is that the module bar.py is installed into install/lib/python2.7/dist-packages/my_package, and there are no __init__.py files in that directory, only one directory lower in msg (it contains __init__.py and _Foo.py and pyc versions).
This is jade with Ubuntu 14.04.

install ros on raspberry pi
I am trying to follow the install for kinetic for the raspberry pi 3.
http://wiki.ros.org/ROSberryPi
Its says if I have a raspberry pi 3 I can follow a easy method at:
http://wiki.ros.org/kinetic/Installation/Ubuntu
But I do not have a dedicated terminal and need to ssh into the raspberry from my pc. The instructions assume that I have ubuntu-mate on the raspberry, as far as I know there is no way to ssh into ubuntu-mate without first going into its desktop.
Are these instructions incorrect ... should ignore the easy recommendation and just follow the body of the instructors that follow in ROSberryPi. These instructions seem to work somewhat but there are issues accessing some of the packages that I have been unable to resolve. I am using realVNC(vncviewer) to ssh in to pi.
I am using 'catkin build'
I will re-flash my sdcard with raspbian and go though the procedure again...but if anyone has some input please let me know.
Thank you for your time.

Unable to find ros-indigo-gazebo7-ros-pkgs
I have just installed ROS Indigo, along with Gazebo 7 from the separate Gazebo site. According to this page, [Using a specific Gazebo version with ROS](http://gazebosim.org/tutorials/?tut=ros_wrapper_versions#UsingaspecificGazeboversionwithROS), I should be able to install ros-pkgs from Debian with (I believe) the following name: `ros-indigo-gazebo7-ros-pkgs`.
However, I cannot find this package. I believe I already added the OSR Foundation packages, but perhaps I did not do it correctly. I have

Preferred method to install catkin on Debian stretch

I followed the directions [Debian install of ROS Lunar](http://wiki.ros.org/lunar/Installation/Debian) `apt-get install ros-lunar-desktop-full`
Should I install catkin from packages? or build catkin from source? I tried both attempting building from source first then tried with apt-get

ros installation fail in osx.
Hello I'm Carlos,
I have a lot of troubles in my ROS installation in OSX.
In first place, I had OSX 'EL CAPITAN'. But I had a error in the rosdep step, the error was a conflict with qt4 and qt5. Because of this error I had format my Macbook Air, I thought that the error was produced because I had got a lot of apps and libraries in my computer, and now I have OSX 'SIERRA', but I had the problem again.
Then I saw this post:
http://answers.ros.org/question/242518/kinetic-installation-fails-with-failed-to-detect-successful-installation-of-qt5-error/#245782
And I did the rosdep with the --skip-keys argument.
> rosdep install --from-paths src --ignore-src --rosdistro kinetic -y --skip-keys "libqt5-core libqt5-gui libqt5-opengl libqt5-opengl-dev libqt5-widgets qt5-qmake qtbase5-dev"
Now I solved this error but I have another after with ogre. If I put ogre in --skip-keys then appears other many errors...
The error output is:
> executing command [brew install ogre] Error: No available formula with the name "ogre" ==> Searching for similarly named formulae... This similarly named formula was found: progress ✔ To install it, run: brew install progress ✔ ==> Searching taps... These formulae were found in taps: homebrew/nginx/upload-progress-nginx-module homebrew/php/php55-uploadprogress

Where does ROS install?
Other than brew or apt-get or python libraries, where does the overall ROS installation sequence install its files?
I know a lot goes into ros_catkin_ws
But where else? In other words, if I want to do a full cleanup and uninstall of ROS itself (for example because I think that certain parts of the install have gotten corrupted) what would I delete other than pos_catkin_ws?

How to avoid installing files like setup.bash more than once?
I use "catkin build" and "catkin config --install". Then each package will install for example setup.bash. How can I avoid that. I would like to only install these files in one package.
The reason I would like to do that is that I use CPACK to build a debian package for each ros package. And I get duplicate files in the debian packages.
