Modelling and control of an electric wheelchair virtual reality platform.

Motaung, Mokete Isaac. January 2014 (has links)
M. Tech. Electrical Engineering. / Discusses how to develop the kinematic and dynamic model and the controller for the 2-DOf motion platform used in an augmented reality environment for wheelchair driving. This comes as a motivation to help to train disabled and elderly people to drive wheelchairs.. With accurate inverse dynamic model, it is possible to achieve high performance control algorithms of robots and direct dynamic model is required for their simulation. The other part of this research was to model and control the roller for the feedback of the wheelchair wheels.

Virtual Reality bei Kärcher

Seibold, Andreas, Stelzer, Ralph, Saske, Bernhard 25 September 2017 (has links)
Die Firma Kärcher wurde 1935 von Alfred Kärcher in Stuttgart-Bad Cannstatt zur Entwicklung und Herstellung industrieller Produkte auf dem Gebiet der Heiztechnik gegründet. Der erste Heißwasser-Hochdruckreiniger Europas entstand 1950 am neuen Stammsitz in Winnenden und bedeutete für Kärcher den Durchbruch in der Reinigungstechnik. Ein weiterer Meilenstein in der Firmengeschichte war die Einführung des ersten tragbaren Hochdruckreinigers und die damit verbundene Erschließung des Consumer-Marktes 1984.

Kombinierter Einsatz von Augmented Reality in virtuellen Umgebungen

Stelzer, Ralph, Saske, Bernhard, Steindecker, Erik 28 September 2017 (has links)
Virtual Reality (VR) und Augmented Reality (AR) sind innovative Technologien, die in der modernen Entwicklung, Herstellung und Nutzung von Produkten zum Einsatz kommen. Bisher werden beide Technologien nicht gemeinsam genutzt, obwohl eine Kombination in bestimmten Fällen erhebliches Potenzial zur Kosteneinsparung besitzt. Die VR-Technologie wird vorrangig In der Produktentwicklung eingesetzt um Kosten für physische Prototypen einzusparen. Bei der Montage oder der Wartung komplexer Produkte hingegen kommt die AR-Technologie zum Einsatz. Dabei wird der Servicetechniker durch Arbeitsunterlagen, die über ein Display in sein Sichtfeld projiziert werden, bei seiner Tätigkeit unterstützt. Um die Qualität der Arbeitsunterlagen für AR-Systeme schon während der Produktentwicklung zu sichern und einen Schulungsvorlauf beim Servicepersonal zu erreichen, ist die Evaluierung dieser Arbeitsunterlagen bereits am virtuellen Prototyp eines künftigen Produktes sinnvoll. Mit der Kombination von AR und VR Technologie in einem integrierten System sollen für diesen Ansatz die Voraussetzung geschaffen werden. Der Beitrag beschreibt die notwendigen Grundlagen und stellt die Entwicklung eines Systems vor, welches die Wahrnehmung von AR-Informationen am virtuellen Prototyp ermöglicht. Anhand eines gewählten Wartungsszenarios wird das notwendige Vorgehen zum Erstellen von virtuellen Prototyp und AR-Arbeitsunterlagen erläutert und Gestaltungsparameter beschrieben. Basierend auf diesem Szenario wird das entwickelte System in einer Benutzerstudie getestet und Vorschläge für die weitere Entwicklung abgeleitet.

Development of a reconfigurable assembly system with enhanced control capabilities and virtual commissioning

Niemann, Johan January 2013 (has links)
Thesis (M. Tech. (Engineering: Electrical)) -- Central University of technology, Free State, 2013 / The South African (SA) manufacturing industry requires developing similar levels of sophistication and expertise in automation as its international rivals to compete for global markets. To achieve this, manufacturing plants need to be managed extremely efficiently to ensure the quality of manufactured products and these plants must also have the relevant infrastructure. Furthermore, this industry must also compensate for rapid product introduction, product changes and short product lifespan. To support this need, this industry must engage in the current trend in automation known as reconfigurable manufacturing. The aim of the study is to develop a reconfigurable assembly system with enhanced control capabilities by utilizing virtual commissioning. In addition, this system must be capable of assembling multiple different products of a product range; reconfigure to accommodate the requirements of these products; autonomously reroute the product flow and distribute workload among assembly cells; handle erroneous products; and implement enhanced control methods. To achieve this, a literature study was done to confirm the type of components to be used, reveal design issues and what characteristics such a system must adhere to. Software named DELMIA was used to create a virtual simulation environment to verify the system and simultaneously scrutinize the methods of verification. On completion, simulations were conducted to verify software functions, device movements and operations, and the control software of the system. Based on simulation results, the physical system was built, and then verified with a multi agent system as overhead control to validate the entire system. The final results showed that the project objectives are achievable and it was also found that DELMIA is an excellent tool for system verification and will expedite the design of a system. By obtaining these results it is indicated that companies can design and verify their systems earlier through virtual commissioning. In addition, their systems will be more flexible, new products or product changes can be introduced more frequently, with minimum cost and downtime. This will enable SA manufacturing companies to be more competitive, ensure increased productivity, save time and so ensure them an advantage over their international competition.
