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.
RAFCON is written in Python, can be extended with plugins and is hard- and middleware independent.
The sophisticated graphical editor can be used for the creation, execution and debugging of state machines.
Share and reuse your state machines in form of libraries, stored as JSON strings in text files.
Before installing RAFCON, Python >=2.7, 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 for Ubuntu 16.04
# rafcon needs gtk > 3.20; the easiest way to install it is installing gnome3 sudo add-apt-repository ppa:gnome3-team/gnome3-staging sudo add-apt-repository ppa:gnome3-team/gnome3 sudo apt update sudo apt dist-upgrade # restart system sudo apt-get install python-dev python-pip libcairo2-dev gir1.2-gtksource-3.0 python-gi-cairo sudo -H pip install --upgrade pip sudo -H pip install --upgrade setuptools
Installation requirements for Ubuntu 18.04
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
If you are not using Ubuntu 16.04 or 18.04, please make sure that the following packages are installed:
- Python >=2.7
- pip (recent version required: v18 known to be working)
- python-setuptools (recent version required: v40 known to be working)
pip install rafcon --user
--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
pip install --user "pycairo<2.0.0,>=1.10.0"
If you are using Python 3.4, you will need a
pip version <= 8. Run the following command, to downgrade
pip install --user --upgrade pip==8
Of course you can also directly use the RAFCON sources from GitHub.
cd /install/directory git clone https://github.com/DLR-RM/RAFCON rafcon
No matter which installation option you choose, RAFCON can be started from any location using (make sure
~/.local/bin is in your
PATH environment variable):
If you want to uninstall RAFCON, all you need to do is call
pip uninstall rafcon
