ROS Installation Notes

ROS Groovy

Run sudo rosdep init and rosdep update as mentionned in the installation wiki

Install catkin for Python 3 support:

git clone git:// -b 0.1.9
cd catkin_pkg
sudo python3 install

git clone git://
cd catkin
sudo python3 install

ROS Fuerte

MORSE is based on Blender and requires Python 3. Python 3 is partially supported by ROS Fuerte.

First, install MORSE using the installation instructions. Make sure to set the BUILD_ROS_SUPPORT parameter to ON when calling cmake! eg.:

  1. Install ROS Fuerte if needed:

  2. Install Python 3 using your system package manager (available in Ubuntu >= 11.04) or manually from the sources, and make sure your $PYTHONPATH variable includes the Python 3 libraries:

    sudo apt-get install python3-dev
  3. Install PyYAML with Python3 support (package python3-yaml on Debian/Ubuntu, or you can get the sources from ) and build it using python3:

    tar xvf PyYAML-3.10.tar.gz
    cd PyYAML-3.10
    sudo python3 install
  4. Install rospkg using Python3:

    sudo python3
    git clone git://
    cd rospkg
    sudo python3 install
  5. Open a terminal and check if everything is correctly set. Therefore, open a terminal and type:

    morse check

    If successful, the following line will be printed after some other information about your configuration:

    * Your environment is correctly setup to run MORSE.

  6. Done. You can start having fun with MORSE and ROS!


  • urandom error : make sure your python3 version is equal to the one in Blender.
  • No module named 'rospkg' : install rospkg with Python3 as in ROS Fuerte #4
  • No module named 'roslib' : source /opt/ros/***/setup.bash.
  • No module named 'error' : Yaml for Python2 is running instead of Python3, fix your PYTHONPATH.
