Nowadays, technical devices such as electromechanical energy transducers, motors and generators are higher and higher utilized. However, these devices have a very complicated geometry with many technical details to master. A proper design tool with some basic assumptions such as accuracy or user friendliness could support the designers during work. The idea is to utilize concept of the virtual reality. As a preliminary work, a particularly simple model is chosen which defines the relations between selected values concerning the dimensions of a machine and its output parameters. The main focus is put on the relation between the external diameter and the rotor length. A software tool is developed which can be used to show how the changes in machine dimensions influence the torque, power, power losses and efficiency of the machine.

This paper presents results of research in time consumption of actual and virtual assembly of a bus air-conditioner compressor using an MTM analysis of basic motions. Definitions of work time, time consumption and work consumption arc compared as they arc often used interchangeably in the literature. The article substantiates the subject and discusses the essence and objectives of research in time consumed by assembly processes. It also presents characteristics of the MTM methodology of analysis of basic motions, and steps required within its framework in order to determine time consumption. The article also discusses EON ICATCHER, a passive, multidisplay, 3D projection system, basic software and stages of determining time consumption involved in assembly of an air-conditioner compressor in Virtual Design Lab. The actual workstation used for assembly of the compressor is compared with a virtual workstation designed using CATIA software. Results established using the MTM analysis of time consumed by actual and virtual assembly operations are presented in tables and analyzed. The research has shown that application of the MTM methodology combined with VR technology makes it possible to provide fast testing of duration of assembly processes performed in a complex manner and to prepare their implementation by taking into account several variants of parts configuration.

Even if the era of Industry 4.0 has reached, the planning of a factory layout is a discipline, which leans on manual planning tools. By using several optimization methods, it is now possible to automatize the necessary steps in the rough planning phase and to calculate the possibilities of positioning with regard to the target function. The calculation is based on the design data of the factory. To perform an automatized optimization, the whole model should be transformed into a mathematical describable form. For this purpose, methods from the graph theory will be used. These methods allow the positioning of objects on the discretized floor plan. After the positioning has finished, the visualization of the model takes place. The preparation of the model has been implemented in the Unreal Engine. The advantage of this is visualization almost in real time in an immersive environment in commercial used Head-Mounted Displays.

Die Fabrik- und Layoutplanung ist eine Planungsdisziplin, welche auch heute im Zeitalter der Industrie 4.0 noch verbreitet auf manuelle Planungswerkzeuge zurückgreift. Mit Hilfe verschiedener Optimierungsverfahren ist es nun möglich, die Planungsschritte im Bereich der Grobplanung zu automatisieren und Positionierungsmöglichkeiten je nach gewünschter Zielfunktion berechnen zu lassen. Die Berechnung stützt sich dabei auf die Konstruktionsdaten der Fabrik oder Hallenmodelle. Um eine automatisierte Optimierung durchführen zu können, ist das Gesamtmodell jedoch zunächst in eine mathematisch beschreibbare Form zu überführen. Hier wird auf Verfahren aus der Graphentheorie zurückgegriffen, welche die Positionierung der Objekte auf dem diskretisierten Grundriss ermöglicht. Im Anschluss an die Positionierung erfolgt die Visualisierung. Die hierfür notwendige Aufbereitung des Modells wurde in der Unreal Engine umgesetzt. Dies bietet den Vorteil, dass das virtuell geplante Layout nahezu in Echtzeit über kommerziell verfügbare Head-Mounted Displays immersiv dargestellt werden können.

Contemporary development of information technology is this stage of civilization called information society in which human learns to transform information into the knowledge. An advantage of this stage is that it allows to effectively adapt to rapidly changing economical and political situations. However, its uncontrolled effect is the phenomena of creating the „virtual reality”. In such reality the information is constructs the illusions and artificial worlds in the human mind. The research on perceptual and memory processes uncovers the mechanisms of such construction which are often used to control the consumer and voter choice in economic and political market. The paper presents some examples of such control in both, the investment behavior on stock market, and the voter behavior under the influence of the negative political campaigns. The analyses of this controlled behavior in the light of cognitive mechanism of information processing allow to look differently on the classic notions of truth and freedom in decision making.

Introduction: Dental students invest many hours in manual dexterity training to prepare themselves for the clinics. Exercising on plastic has the advantage of learning within a standardized environment; continuing exercises on prefab teeth are unrealistic as plastic does not generate a training facility for clinical problem solving. Introducing a virtual learning environment with haptics and 3D models with realistic pathology (the Simodont) enables students to become competent before they enter clinics, assuming that the competences are easily transferred from virtual reality to reality. Therefore a study has been carried out to investigate if skills developed in virtual reality are transferred to reality. Methodology: Twenty-eight students participated in the study; 10 trained in the traditional phantom lab, 10 trained in the Simodont lab and 8 acted as a control group. Performance was tested before, during and after training. Result: It turned out that all students performed better after little or more training, independent of the training environment. Conclusion: Skills developed in virtual reality on the Simodont were transferred to reality.

During the years common understanding of the possibilities and perspectives of Virtual Reality (VR) usage has been changed. It is thought that VR is mainly used in entertainment purposes, but it is being used already for many years in different industries, and now with easier access to the hardware it became a helpful and accessible tool that could be used and developed in any field of human activities. In manufacturing, immersive technologies are mainly used nowadays for the visualisation of processes and products combining those visuals into the factory Digital Twin (DT) which is possible to view from the inside look. This feature is already being used in several manufacturing simulation tools, which enable to view onto industrial line / robotic cells via Virtual Reality glasses. However, the potential of using simulations with VR in manufacturing is not fully uncovered. The main aim of this, industrial robotics targeted research is to enable besides simulation also universal control algorithms through Virtual Reality experience, produced by game engine Unity3D, which can be easily modified for a wide range of industrial equipment. The primary outcome of this work is the development of the synchronisation model of real and virtual industrial robots and experimental testing the developed model in Virtual Reality and shop floor labs.

Standardized and universal solutions for industrial robot integration are increasingly urgent requirements for companies looking for machine interconnectivity, and flexibility in creating tailor made manufacturing systems. These solutions must be supported by modular and open-source components able to easily integrate new control methods and advanced Extended Reality (XR) interfaces. Robot Operating System (ROS) has proven to be a reliable standard for industrial robot integration. ROS compatibility software is provided by many producers and allows for the implementation of modular control units by unifying development practices along the same libraries and methods. Digital Twins (DT) of industrial equipment and processes offer a solid base to develop innovative digital tools relying on synchronization between physical and digital entities and to easily setup intuitive XR interfaces for teleoperation and programming. This work presents the integration of the OMRON TM5-9000 collaborative industrial robot into the IVAR laboratory DT system at Tallinn University of Technology. By using Unity3D game engine and developing a ROS package for the specific machine, the digital model of the collaborative robot is integrated into the existing twin. Synchronization with the real counterpart is provided by MQTT protocol while a robot user interface is developed in Unity and provides robot joints visualization and remote control.

Developing Western societies are characterized by growing numbers of older people. This trend will increase in coming decades. Medicine and health care of developed countries has to stand against new needs of societies rich in people over sixty years old. This paper will briefly review new technologies and ways of treating disorders of older people on the one hand, and reception of these methods by older patients on the other hand. We briefly describe therapeutic methods used in clinical neuroscience dividing them into 3 categories: therapies based on implantation of external devices into the organism, therapies using video games, and therapies using virtual reality. These therapies will be discussed according to three rules, that have been proposed considering the approach for effective therapeutic methods targeting older people. It can be assumed that older people tend to be afraid of using unknown solutions, even to improve their own health states. Contrary to this claim, most of researches report very high rate of acceptance of aforementioned techniques by older people. However, laboratory teams should treat older people with extreme care so as to not provoke aversion to technologies used in intervention
