ROS Installation Notes

ROS Fuerte

MORSE is based on Blender and requires Python 3.2. Python 3 is partially supported by ROS Fuerte from patch release 1.8.15, which was rolled out on 20/07/2012. Any ROS Fuerte installation from that day on works fine with MORSE.

  1. Install ROS Fuerte if needed: http://www.ros.org/wiki/ROS/Installation

  2. Install Python 3.2 using your system package manager (available in Ubuntu >= 11.04) or manually from the sources, and make sure your $PYTHONPATH variable includes the Python3.2 libraries.

  3. Install PyYAML with Python3 support (package python3-yaml on Debian/Ubuntu, or you can get the sources from http://pyyaml.org/. Install the source by running python3.2 setup.py install to be sure to have the Python 3 libraries.

  4. Install rospkg using Python3.2:

    git clone git://github.com/ros/rospkg.git

    cd rospkg

    sudo python3.2 setup.py install

  5. Done. You can start having fun with MORSE!

ROS Electric and Diamondback

To get a working setup suitable for using ROS Electric or Diamondback with MORSE, please follow the following steps:

  1. Install ROS Electric Emys (check http://www.ros.org/wiki/ROS/Installation if needed)

  2. Install Python 3.2 using your system package manager (available in Ubuntu >= 11.04) or manually from the sources, and make sure your $PYTHONPATH variable includes the Python3.2 libraries.

  3. Install PyYAML with Python3 support (package python3-yaml on Debian/Ubuntu, or you can get the sources from http://pyyaml.org/. Install the source by running python3.2 setup.py install to be sure to have the Python 3 libraries.

  4. Due to the lacking Python 3 compatibility, you have to overlay some ROS stacks. You can use rosinstall to this end:

    ROS Electric:

    rosinstall ~/ros-py3  http://ias.cs.tum.edu/~kargm/ros_electric_py3.rosinstall

    (Assuming your ROS is installed in /opt/ros/electric and your overlay should be created in ~/ros-py3)

    Note: rosinstall will create a new setup.bash in the folder ~/ros-py3/. It has to be sourced (instead of the original setup.bash) before using MORSE with ROS.

    You can also use MORSE with ROS Diamondback:

    rosinstall ~/ros-py3 http://ias.cs.tum.edu/~kargm/ros_diamondback_py3.rosinstall

    (assuming your ROS is installed in /opt/ros/diamondback and your overlay should be created in ~/ros-py3)

    The ROS-stacks ros, ros_comm and common_msgs are overlayed by Python3-compatible versions and need to be rebuild:

    rosmake ros && rosmake ros_comm && rosmake common_msgs

    Note: Rebuilding the common_msgs stack allows you to use all messages in this stack for communicating between MORSE and ROS. If you want to use any other messages, make sure the source-files are Python2 AND Python3 compatible! This can be achieved by simply rebuilding the ROS-packages of the messages with rosmake –pre-clean when you are running the patched ROS-stacks (make sure to source the right setup.bash!), e.g.:

    rosmake --pre-clean sensor_msgs
