Safety Issues Concerning Installation of Welding Robots

The aim of this research is to summarize the safety measures related to the application of welding robots, as well as to apply them in the ÓE-Cloos Robot Welding Laboratory of Bánki Faculty at Óbuda University. This article describes the safety requirements for welding robot systems, the requirements for commissioning and safe operation. The concluding part of the dissertation presents the preparation and implementation of the installation of a new robot cell in the laboratory.

Singularity measurement in the Cyber-physical and intelligent robot systems laboratory

In the building mechatronics research centre of University of Debrecen, Faculty of Engineering, a new laboratory has been designed, named “Cyber-physical and intelligent robot systems laboratory”. The possibility to design and test unique and platform-independent systems was among the main goals, hoping that the system itself and its advancements may later be used in manufacturing industries as well.Fulfilling the needs of “Industry 4.0” is a challenging task, as it requires every single device (e.g. industrial robots) to be connected to the same network, where they may be monitored and controlled. However, there are some factors that limit this, such as the periodical “instability” that some machines have, caused by singularity points.The following material studies these so-called singularities of a KUKA KR5 industrial welder robot placed in a robot cell, from an engineering viewpoint.

Application of Additive Manufacturing for the Repair of Forging Dies

In this paper the investigated conditions and possibilities of repairing forging dies with high precision robotic MAG welding are presented. Different welding wire electrodes were examined and compared by their processability. Productivity, process stability, slag and fume formation were in the focus of investigation. Metallographic tests were carried out to validate the compliance of welded layers. Based on the performance of the wire electrodes, recommendations have been elaborated for the procedure specification and also for further investigation. Some robot cell layouts have been designed adapting to the special working environment and requirements of the welding procedure.

Reconstruction, Adapter Design and Application of a Nokia Puma 560 Robot's Gripper on a Robot Cell Integrated KUKA KR5 Industrial Robot

This summary details the steps that were necessary to fasten a Nokia Puma 560’s gripper to a KUKA KR5 industrial robot found at University of Debrecen, Department of Mechatronics and also demonstrates its applications in the robot cell designed around its usage. It also includes the inspection and reconstruction of said gripper, and the 3D designing of its adapter. The adapter is intended for the KUKA KR5 robot, which is later manufactured using PRO-PLA 3D printing. The KUKA KR5 will also have a robot cell designed and built around it, for educational purposes.
