D5.1 Report and demonstrator of developed strategies for safety in HRC tasks with collaborative and high-payload robots (Module#10) - ABSTRACT
flexibility and safety are forming together the main objective of any manufacturing company. Unfortunately, it is not easy to fulfil all these aims together in an optimal way, especially during complex and collaborative tasks between human and heavy-duty robots. Fraunhofer-Team during the Sharework project developed a reliable and redundant embedded velocity controller along with multi-modal global perception system taking safety and efficiency into account. In addition to that, the team has developed a dynamic risk assessment tool for flexible enhanced collaborative operation modes. The Modules of this WP aim to 1) reduce 40% of the effort for risk assessment of complex cells while enabling safe and flexible switching between various collaborative operation modes, 2) increasing the reliability of the velocity control using the redundance architecuture and 3) increase more than 50% of overall efficiency of the system with respect to standard safety zone based systems. The three proposed modules form together a platform which could help the user to plan and build fenceless optimized collaborative robot cells without huge planning effort or rigid safety procedures.
