Documentation for cedar 2.0 (yellow jester)

Cognition, embodiment, dynamics, and autonomy for robots

Welcome to cedar!


cedar is a C++ library that provides tools for scientific work in the fields of cognition, embodiment, dynamical systems, and autonomous robotics. cedar is primarily being developed at the Institut fuer Neuroinformatik in Bochum, Germany. It is a complete rewrite of a collection of powerful, yet somewhat fragmented code. cedar captures our scientific knowledge and ideology in a coherent framework. A lot of effort goes into keeping the different parts of cedar compatible to each other. Linking up perception and motor control of a robot and putting some cognitive processing in between should not be constrained by programming issues, but only be a question of applied concepts. cedar provides a tool aimed at facilitating the connection of modules to create robotic architectures. You can focus on "what" to connect, keeping the effort of "how" to connect it very low.


We have assembled documents that assist users of cedar to get productive with this framework. Please refer to the category that fits your profile the most:

  • If you just want to use cedar, have a look at our tutorials on how to use the processing framework and add custom steps.
  • If you want to add new features to cedar or fix existing bugs, please take a look at the developers' guide .

Installing cedar

Please refer to the readme page or the file in the root of the repository to find instructions on how to install cedar. If you are experiencing troubles during installation or use of cedar, please take a look at our troubleshooting document (also found as in the root directory of cedar).

Version notes

How to get this documentation

This documentation is included in your copy of cedar. cmake will create a Doxyfile in your build folder. You need Doxygen to create this documentation from the generated Doxyfile (see "" file for more information about the build system). Doxygen will create an HTML and a PDF output of the code documentation and additional pages like this introductory page. Feel free to browse through the class documentation, or just dig into the concepts incorporated in the implementation. You can also start with one of our tutorials, to get accustomed to the ways cedar can be used.
