A Model-Driven Engineering Approach for ROS using Ontological Semantics

This paper presents a novel ontology-driven software engineering approach for the development of industrial robotics control software. It introduces the ReApp architecture that synthesizes model-driven engineering with semantic technologies to facilitate the development and reuse of ROS-based components and applications. In ReApp, we show how different ontological classification systems for hardware, software, and capabilities help developers in discovering suitable software components for their tasks and in applying them correctly. The proposed model-driven tooling enables developers to work at higher abstraction levels and fosters automatic code generation. It is underpinned by ontologies to minimize discontinuities in the development workflow, with an integrated development environment presenting a seamless interface to the user. First results show the viability and synergy of the selected approach when searching for or developing software with reuse in mind.Comment: Presented at DSLRob 2015 (arXiv:1601.00877), Stefan Zander, Georg Heppner, Georg Neugschwandtner, Ramez Awad, Marc Essinger and Nadia Ahmed: A Model-Driven Engineering Approach for ROS using Ontological Semantic

Shisha smokers’ determinants of use, knowledge and perception towards shisha (waterpipe) smoking in Penang, Malaysia

Background: Tobacco smoking is a serious health problem worldwide. Malaysia as many of south Asian countries faces the challenge of rising tobacco consumption. Despite the apparent spread of Shisha smoking phenomenon among Malaysian population, little is known about the safety concerns and determinants of Shisha smokers in this community. Objectives: This study aimed to determine the social determinants of Shisha smoking among Malaysian population in Penang Island, Malaysia and to explore their health related knowledge and perception toward Shisha smoking. Methods: The survey was conducted using simple random sampling by randomly distributing self-administered questionnaires to consumers in Shisha lounges located in Penang Island. Statistical analyses were performed using the Statistical Package for Social Science (SPSS) version 20. Results: A total number of 171 (42.75%) of respondents participated in this study. Mean age was 21.5±4.4 years. The majority were male, Malay (79.6%, 63.1% respectively). About 97.1% of respondents smoke Shisha either alone or with tobacco cigarettes. The majority (63.1%) started Shisha smoking at an age ≤ 20 years old, always in a café' (72.2%), share Shisha smoking with others (81.6%). Only 35.9% of respondents reported smoking Shisha daily. 71% reported smoking ≤ 7 bowls per week. 50.5% claimed smoking Shisha for more than 60 minutes per session. Boredom, outing and meeting with friends and family ranked first among the motives for smoking Shisha. Regarding knowledge about Shisha smoking, the majority believes that cigarettes are more harmful, more addictive and has more nicotine than waterpipe (60.2%, 71.8% and 67%; respectively). A large proportion (66%) of respondents believes that Shisha smoking doesn't transmit hepatitis infection. The majority of respondents perceived Shisha smoking acceptable by society and parents, compared to cigarettes (67% and 60.2%; respectively). The vast majority of respondents believe that Shisha smoking relieves stress and tension (77.7%), while the minority believes that Shisha smokers have more friends than non-smokers. Regarding access to Shisha, half of respondents agreed that Shisha is easily accessible than cigarettes. The majority of respondent foresees increasing popularity of Shisha smoking in the next 5 years (83.5%). Conclusion: This study showed that there is a high prevalence of Shisha smoking among the Malaysian youth associated with false believes about its health effects. Further studies involving larger population are encouraged

Aufzeigen, wo Automatisierung sinnvoll ist

Wirtschaftlicher produzieren mithilfe eines höheren Automatisierungsgrads - das ist das Ziel der Automatisierungs-Potenzialanalyse des Fraunhofer-Instituts für Produktionstechnik und Automatisierung IPA

Simulation. Einführung und Beispiele in Visual Components 3D Automate

Ziele des Themenblock Simulation: - Simulation von Roboteranwendung - Einordnung in die Programmierverfahren - Vor und Nachteile der Offline-Programmierung - Funktionen und Nutzen von Simulationssystemen - Visual Components 3D Automate kennenlernen und anwenden - Komponenten in Modell importieren - Parametrisierung der Komponenten - Programmierung von Handhabungssequenzen - Verknüpfen mehrerer Sequenzen zur Gesamtaufgabe - Erstellen einer ausführbaren PDF-Datei - Beispielapplikation: Entnahme und Sortierung von Kisten in ein Rega

Roboter auch für anspruchsvolle Prozesse

In der Montage ist der Automatisierungsgrad bis dato relativ gering. Entsprechend hoch ist daher das Potenzial, die anstehenden Aufgaben mit Unterstützung von Robotern auszuführen

ROS engineering workbench based on semantically enriched app models for improved reusability

In this work, the ReApp Engineering Workbench and its underlying semantically enriched app models are presented. The usage of a model, which describes the apps functionality, interfaces and other attributes, allows the utilization of engineering tools for code generation and automated testing. Further, it ensures the compatibility of the generated interfaces, which in turn enhances the reusability of the developed apps in larger applications

EuRoC - The Challenge Initiative for European Robotics

The EuRoC initiative is committed to launch three industry-relevant challenges aimed at sharpening the focus of European manufacturing through a number of application experiments, while adopting an innovative approach which ensures benchmarking and performance evaluation. Within an open call framework, three stages of increasing complexity and a total financial support of 7 M??? for competing teams will level the playing field for new contestants, attract new developers and new end users toward customisable robot applications, and provide sustainable solutions for creating and running future European robotics challenges

Model-based Approach for the Automation and Acceleration of the CE-Conformity Process for Modular Production Systems: Future Requirements and Potentials

In the ultra-flexible factory, production machines reconfigure themselves ad-hoc depending on incoming production orders. Consequently, the IFF institute has developed a modular cyber-physical system (CPS) that consists of configurable robotic components. This paper is motivated by the need to reduce the effort and time associated with the CE conformity process for manufacturing systems with frequent reconfigurations, thus minimizing non-value adding machine downtime and increasing Overall Equipment Effectiveness (OEE). It presents an approach for an automated assistant system for the required risk assessment process using a database of previous CE conform system configurations and a reasoner that is able to verify the existence of a CE conform configuration that supersedes the hazards and risks of the new configuration. This allows the protective measures listed in the previous CE conform configuration to be reused, as well as a large part of the respective CE documentation
