【Title】Security management for Cobot / human coexistence
【Speaker】Dr. Damien Chablat
 
【Abstract】The installation of industrial robots requires security barriers, a costly, time-consuming exercise. Collaborative robots may offer a solution; however, these systems only comply with safety standards if operating at reduced speeds. The purpose of this presentation is to describe the development and implementation of a novel security system that allows human–robot coexistence while permitting the robot to execute much of its task at nominal speed. This presentation describes the system’s mechanical, software and control architecture. The system is demonstrated experimentally on a collaborative robot and is compared with the performance of a state-of-art security system. Both a qualitative and quantitative analysis of the new system is carried out.The security system is defined by three modes: a nominal mode, a coexistence mode and a gravity compensation mode. Mode transition is triggered by three lasers, two of which are mechanically linked to the robot. These scanners create a dynamic envelope around the robot and allow the detection of operator presence or environmental changes. To avoid velocity discontinuities between transitions, a novel time scaling method is introduced.
 
【Bio】Damien Chablat obtained his doctorate in Mechanical Engineering from the Ecole Centrale de Nantes and the University of Nantes in 1998. For a year he worked at McGill University's Intelligent Machinery Centre with Professor Angeles. He joined the CNRS (Centre National de la Recherche Scientifique) in 1999 to work within the Robotics group of the Institut de Recherche en Communications et Cybernétique de Nantes (IRCCyN). He became a senior researcher at the CNRS in 2011. Since 1 January 2017, IRCCyN has been renamed LS2N, Laboratoire des Sciences du Numérique de Nantes. He is now the team leader of a robotics team studying humanoid robots, bio-inspired robots and the interaction between humans and robots. His research interests include robotics, parallel manipulator design and human fatigue assessment for industrial tasks.
 
【Title】Multidisciplinary design optimisation and robust design approaches applied to concurrent design

【Speaker】 Prof. Fouad Bennis
 
【Abstract】The increasing economic competition of all industrial markets and growing complexity of engineering problems lead to a progressive specialization and distribution of expertise, tools and work sites. Most industrial sectors manage this fragmentation using the concurrent engineering approach, which is based on tools integration and shared databases and requires significant investments in design and work organisation. Besides, the multidisciplinary design optimisation (MDO) is more and more used as a method for optimal solutions search with regard to multiple coupled disciplines. The presentation introduce the basic concept of the MDO and robustness in product and process design optimisation and give some industrial examples introducing an innovative multidisciplinary optimisation method based on robust design techniques.
