Welcoming the new Master’s first semester students
The Institute of Transmission Technology, Machine Dynamics and Robotics welcomes all new first-semester Master’s students!
The summer semester started on 03.04.2023 and with it the Master’s program for many first-semester students. At a welcome barbecue organized by the Mechanical Engineering student council, we were able to introduce our institute and talk to students.
Sophie Charlotte Keunecke, Nils Brückmann, Vincent Brünjes and Thomas Knobloch welcomed the new Master’s students from the Faculty of Mechanical Engineering at the IGMR. This allowed the students to make their first contacts with the institutes and also get to know various projects. A special highlight was the presentation of the Robot Companion by Maximilian Hilger!
We would like to thank the Mechanical Engineering student council for this great offer and your immense commitment.
We wish all new first-year students all the best for their studies and an unforgettable time at RWTH and the Faculty of Mechanical Engineering.

Successful workshops with the Technical University of Liberec
Four different institutes of the Technical University of Liberec introduced us to their fascinating projects and interesting presentations before we worked out common research interests in smaller workshops.
The Technical University of Liberec and the IGMR can already look back on many years of joint exchange and close cooperation; the restrictions imposed by the pandemic have not weakened this, but have severely limited it.
Therefore we are pleased to be able to strengthen our cooperation with new, joint research interests in the future.

Interactive learning with ROS: The new course in RWTHJuypter
We are pleased to present our latest ROS course, which is integrated as JupyterHub under RWTHJupyter. This course offers an interactive way to learn and deepen the basics of ROS (Robot Operating System).
ROS is an open source framework that allows developers to simplify the control of robots and their sensors. It provides a set of tools and libraries that make it possible to simplify the communication between the different components of a robot and speed up the development of applications.
Our course covers the main topics required to work with ROS. These include using ROS nodes, topics, services and actions, using ROS libraries such as tf (transform library) and moveit (motion planning library), and developing your own ROS packages. Working with different robot platforms is also covered.
Special emphasis is placed on the use of Jupyter notebooks to make the course interactive and vivid. This allows students to complete the examples and exercises directly in the course environment and see the results immediately.
We would like to thank Quantstack for their support in developing the course and their developments on JupyROS. By using Jupyter notebooks and JupyROS, we have been able to create an intuitive and user-friendly environment that makes learning ROS quick and easy.
We hope that our ROS course will be useful for both beginners and advanced developers and look forward to welcoming many participants.

Cross section group: Application Dynamics
The Application Dynamics team is made up of members from all IGMR research areas. This allows the skills in vibration analysis and machine dynamics to be optimally combined with the expertise and many years of experience in power transmission and robotics. This fusion of the Institute’s internal research priorities enables solutions to be found to problems that require both technical knowledge of dynamics and application-specific expertise. This cross section of knowledge is applied, for example, in the form of a needs-based investigation and exploitation of the dynamic effects of a system. The focus is on applications in robotics and gearing, but also covers all types of mechanical motion systems. The current research horizon ranges from kinematic redundancy and high-speed trajectories to the use of neural networks to extend the workspace through innovative object manipulation.

Review Summerschools ROBO and ROCNI 2022
The Summerschool serves to educate and deepen the knowledge of interested students. The Summerschool ROBO and ROCNI are offered by the International Academy (IntAc) and conducted by the Institute of Mechanism Theory, Machine Dynamics and Robotics (IGMR) at RWTH Aachen University. The theoretical basics are esxtended by the practical application of simulations and on the real robot in the laboratory of the IGMR.

German Robot System Integration Championship 2022
Once again IGMR successfully participated in the German Championship (formerly the Olympics) in Robot System Integration at FANUC Germany!
This year’s task was the variable loading and palletising of boxes. In addition to the independent design of the entire cell, both real and virtual, the implementation also included the digital drawing of components, the setting of safety functions, error detection, user friendliness and instructions, as well as the integration of sensors, actuators and cameras.
Simon Strauch and Florian Menz competed under the team name “IGMR“, while Frederick van Kerkom and Sebastian Polzin took part as the “RWTH“ team. They were accompanied by former participant Sophie Charlotte Keunecke as their coach.
The four students have been working independently with the FANUC Education Cell in the IGMR in their free time over the past few months, learning TP programming and simulation in RoboGuide. The effort was worth it!
Team IGMR presented a very impressive real and virtual Cell installation, implementing every menu option for customer convenience and error handling.
Team RWTH achieved the fastest lap times in both timings with 57 seconds and shone with a very detailed simulation and documentation. We are very proud of all four participants for their great performance!
A special thanks to FANUC Germany for the great implementation and the exceptional cooperation.
The FANUC Education Cell is an essential part of the practical teaching of robotics and offers students the opportunity to try out the handling of industrial robots and the use of frames (coordinate systems) and to carry out or verify their own experiments and measurements.

Presentation of the “ErgoFli” project at the KT Colloquium 2022
The aim of the ZIM-funded project “ErgoFli” is to develop an intelligent, semi-automatic tiling aid. Its intuitive user interface, automated handling of tiles and tile adhesive, and intelligent control system are expected to reduce non-ergonomic postures by up to 66%. The ErgoFli can be moved with a motorised drive and uses linear laying kinematics to lay tiles without direct wall contact using the buttering-floating method. Tiles in two formats, 30x60 cm or 60x60 cm, can be laid in a cross bond. The robot is equipped with a tile and tile adhesive reservoir so that it can be used for at least 30 minutes without refilling and can lay 12 m2 per hour while maintaining the required standard flatness tolerances.
Using a digital twin, an early prototype has already been tested in various scenarios. While the prototype is being designed in standard CAD software, the actual model is being integrated into the Gazebo simulation environment in parallel. This enables continuous integration and testing of control system software packages in application-related scenarios. For example, real test data can be transferred to the digital twin via a closed-loop simulation. The three laser profile sensors of the tile gripper are attached to a prototype gripper and mounted on a UR10 robot arm. The measured values from the sensors can then be transferred to the digital twin in the simulation, despite the different kinematics. In this way, the position control of the gripper can be integrated into the overall system at an early stage by measuring the joint widths.

Automatic Robot-Guided Form Scan and Coating
In this project, the forms are detected and their edges are realized by a laser scanner mounted on the end effector of the robot. The collected data are synchronized and filtered, and a suitable trajectory is created for coating the inner surface of the forms. Several variables, such as the speed of the nozzle, distances and gaps, the size of the nozzle and the outlier for a homogeneous coating can be selected during the trajectory planning.
Motivation
The project was initiated with the motivation to increase flexibility in scanning and coating various molds.
Method
In the context of this project, synchronization is required between three systems
The sensor software, which is responsible for the acquisition of the data (synchronized with movement of the robot).
The program, which is responsible for post-processing the data and calculating the trajectories for the robot.
The Robot control system, which receives the information of the trajectory and executes it immediately.

Programming courses with the FANUC Education Cell and RoboGuide
One of the key factors in working with robots at the IGMR is not only the theoretical consideration, calculation and optimisation of movement or mechanics, but in particular the practical work and handling of the systems, as well as the various programming tasks. The FANUC Education Cell is at the heart of this practical teaching, and is also an integral part of the Robotic Systems lecture and robotics courses at the International Academy. In addition to the lectures, the IGMR, represented by Carlo Weidemann, winner of the FANUC Olympiad 2020, also offers internal user courses for employees and gives them the opportunity to work independently on the cell.
Are you a student at the RWTH and interested in working with robots such as the FANUC LR Mate 200iD 4S or carrying out projects? Perhaps you have a concrete idea for a thesis involving the robot? Then please contact us. We look forward to hearing from you!
