Broccoli

Broccoli is an open source C++ header-only library for general robotics applications. The library includes tools and algorithms for the control of robots under hard real-time requirements. Broccoli is largely platform-independent - at the chair it is used on QNX Neutrino and LinuxRT.

The project has evolved from refactored code of the humanoid robot project and serves as a development basis for robotics research at the chair. Broccoli has a stable API and is licensed under the GPL v3 license.

AMfe

AMfe is a finite element code written in Python that focuses on

  • modularity
  • extensibility
  • easy prototyping of new methods for research

It originates from the demand to make the assembly of the finite element routine easy accessible to the researcher to be able rapidly test new developed hyper-reduction methods. The code has grown over the past years and has gained a very flexible modular structure that enables researchers to rapidly test new methods for simulation of structures.
