Multidirectional additive manufacturing in arc welding process
In collaboration with the ISF, RWTH Aachen, we at IGMR are researching Multidirectional Additive Manufacturing. In this application for the production of metal components.
Multidirectional Additive Manufacturing enables the production of complex components without support structures, both in the classic FDM process with plastic and with layer-by-layer buildup in the arc welding process. At IGMR, the entire process chain of additive manufacturing is being extended to meet the special challenges of this process from a robotic perspective. This includes the slicing of a virtual component into layers, the subsequent planning of a collision-free structure, the generation of executable robot paths for filling the layers as well as the necessary trajectory planning.

SLAM validation using iGPS
For the validation of localization and mapping algorithms (SLAM) for mobile robots, we use at IGMR the indoor Global Positioning System from Nikon.
SLAM is a classical problem in mobile robotics and still a current and challenging research topic. The current developments are focused in improving SLAM algorithms with respect to a high accuracy, generality, and robustness. For this reason, we validate our SLAM algorithms for mobile robotics with the Nikon iGPS which is used to generate a ground truth with a frequency of 40 Hz and an accuracy of 0.2 mm. In this way, critical inaccuracies and loop closure methods can be much better quantified and analyzed.
