Develop your robotic tasks using an intuitive graphical user interface

RAFCON uses hierarchical state machines, featuring concurrent state execution, to represent robot programs. It ships with a graphical user interface supporting the creation of state machines and contains IDE like debugging mechanisms. Alternatively, state machines can programmatically be generated using RAFCON's API.

Universal application

RAFCON is written in Python, can be extended with plugins and is hard- and middleware independent.

Visual programming

The sophisticated graphical editor can be used for the creation, execution and debugging of state machines.

Collaborative working

Share and reuse your state machines in form of libraries, stored as JSON strings in text files.

Installation preparations

Before installing RAFCON, Python >=3.7, pip and setuptools are required on your system. Most of the other dependencies are automatically resolved by pip/setuptools, but not all of them. Those need be be installed manually, too:

Installation requirements ^^^^^^^^^^^^^^^^^^^^^^^^^

.. code-block:: bash

sudo apt-get install python-dev python-pip build-essential glade python-gi-cairo sudo -H pip install --upgrade pip sudo -H pip install --upgrade setuptools

General requirements ^^^^^^^^^^^^^^^^^^^^

• Python >=3.7
• pip (recent version required: v23 known to be working)
• pdm (recent version required: v2.9.3 known to be working)

Installing RAFCON

.. code-block:: bash

pip install rafcon --user

The --user flag is optional. If not set, RAFCON is installed globally (in this case you normaly need to have root privileges).

If during the installation the error ImportError: No module named cairo occurs, please install pycairo directly via:

.. code-block:: bash

pip install --user "pycairo==1.19.1"

Of course you can also directly use the RAFCON sources from GitHub.

.. code-block:: bash

cd /install/directory git clone https://github.com/DLR-RM/RAFCON rafcon

Start RAFCON

No matter which installation option you choose, RAFCON can be started from any location using (make sure /usr/local/bin or ~/.local/bin is in your PATH environment variable):

.. code-block:: bash

rafcon

On a multi-python setup start rafcon using:

.. code-block:: bash

python -m rafcon

Uninstallation

If you want to uninstall RAFCON, all you need to do is call

.. code-block:: bash

pip uninstall rafcon
