The Human-Robot-Collaboration (HRC) with its variable combination of unique skills represents a future-oriented form of work. Yet, there is a lack of experience in process realization, safety requirements are often not given and economic efficiency is still missing. There are a lot of innovative process solutions in research but industrial conditions are less considered. In this work, the approaches for the realization of standardizable HRCs for assembly operations in the automotive sector will be outlined. The aim is to present simple ways from the idea to series production by considering permitted limits. Based on an industrial application, innovative collaborations are realized with only few hardware and software components. In this context, standard compliant safety is ensured through internal system features and adjusted component designs. Additionally, an approach for HRC safety through real-time monitoring of the endeffector area is presented. As an outlook there is a guideline for HRC realization.}, language = {en} } @inproceedings{BergnerAkanSchmidtVollusetal.2021, author = {Bergner, Christian and Akan, Ferhat and Schmidt-Vollus, Ronald and Heß, Peter and Deuerlein, Christian}, title = {Portable Safety System using Radar for Flexible Human-Robot-Collaboration in a Real Semi-automated Production Line}, series = {Proceedings of the 2nd International Conference on Robotics, Computer Vision and Intelligent Systems ROBOVIS - Volume 1}, booktitle = {Proceedings of the 2nd International Conference on Robotics, Computer Vision and Intelligent Systems ROBOVIS - Volume 1}, publisher = {SCITEPRESS - Science and Technology Publications}, isbn = {978-989-758-537-1}, doi = {10.5220/0010645800003061}, pages = {67 -- 76}, year = {2021}, abstract = {The implementation of a reliable vision system for a human-robot environment is a key issue for the collaborative production industry. The core challenge of human-robot collaboration is to ensure safety. Furthermore, a flexible safety system is required for frequently changing applications and work areas. This paper focuses on the development and application of a workspace monitoring system for safeguarding using radar sensors. The human-robot collaboration cell is designed to enable a flexible integration regardless of the work location. This results in higher productivity. Since no separating protective devices are provided for the cell, safety-oriented monitoring and control by suitable safety sensors is required. The methods to minimize the size of the necessary safety distance will be presented. The experimental validation shows that this safety system with radar sensors performs a reliable workspace monitoring system. The high robustness, reactivity and flexibility of the safet y concept makes this system usable for collaborative tasks in a real industrial environment.}, language = {en} }
