Manipulator-specific path planning for multidirectional additive manufacturing
In a joint research project between the IGMR and the ISF of RWTH Aachen University, research is being conducted on the Multidirectional Additive Manufacturing of metallic components.
With the aid of Multidirectional Additive Manufacturing (MDAM), it is possible to build complex components layer by layer and without the need for support structures. By moving the base plate by means of an industrial robot while the welding gun remains fixed, the component to be printed can always be oriented in such a way that support structures can be avoided. The major challenge lies in the consideration of specialized welding processes with external wire feeding and the use of sensors for process monitoring. This results in a dependency of the orientation of the welding gun compared to the currently printed path.
As part of his master’s thesis, Jan Wiartalla developed a path planning algorithm that calculates an executable and, if possible, continuous path within specified, flat part slices that completely fills the cross-sectional area. This is done robot-specific, so that the algorithm always takes the robot currently in use as well as its limitations into account. A standardized interface allows for the robot model to be easily exchanged and the algorithm can thus quickly be adapted to different test environments. The video illustrates the algorithm’s procedure in a simplified way.

IGMR Seminar: Dr. Michael Cashmore – Plan-Based Robot Control in Real-Time
Mit dem Vortrag von Dr. Miachel Cashmore von der University of Strathclyde startet die virtuelle IGMR Vortragsreihe im Wintersemester 20/21. Wir freuen uns auf einen Einblick in ROSPlan und Plan-Based Robot Control in Real-Time.
Mittwoch, 2. Dezember 2020 16:30 Uhr in Zoom Zoom Meeting Informationen: https://rwth.zoom.us/j/98454895570?pwd=NkpiSWkyaTJtdWlralJrSUtnMDdDZz09 Meeting-ID: 984 5489 5570, Kenncode: 186393

The topic of the seminar will focus on the numerous temporal and numeric challenges that arise in plan execution. If a plan is produced with some flexibility, how it can be executed? In this context the properties of temporal controllability, robustness envelopes, replanning in-situ, and planning concurrently to execution, deliberation in a system of distributed components, in which your actions can affect other parts of a larger system will be discussed.

Robot Companion: A mobile helper in case of need
Robot Companion is a framework to implement robot tracking systems in a simple and cost-saving way. For this purpose, IGMR develops methods for tracking with different sensors (laser, radar, camera), agile path planning and actuation.
The current objective of Robot Companion is to provide a robot for emergency rescue. In doing so, the robot will autonomously follow first responders and enable the transport of materials and equipment, as well as the removal of debris and casualties. A first path to this vision was implemented with the basic module. The basic module has methods for tracking with a camera and laser, and enables autonomous tracking of an operator.
The video shows the tracks of the vertical and horizontal trackers, as well as the state of detection (top right). In a tracking test, 100% accuracy was achieved at low speeds.

Driverless transport systems

Autonomous transportations systems are being integrated into modern plants and warehouses. Trapo AG has developed with the support of IGMR of RWTH Aachen University a leading product in the industry, the Trapo Transport Shuttle (TTS). The IGMR staff was involved in the development and integration of the localization and navigation algorithms, in the creation of the state machines that determine the behavior of the TTS, and in the intensive testing phases. All methods and algorithms were integrated and configured in the ROS middleware. The whole system has already been successfully put into operation at the customer.

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.
