This paper deals with virtual reality in context of Industry 4.0 projects. Due to sufficient computing power, virtual reality allows visualization of virtual objects in both professional and public spheres. With virtual reality, solving complex projects has become much easier, especially of those based on Industry 4.0 standards. Industry 4.0 projects require connection between all systems of modern machines (physical systems, embedded systems, sensors, actuators, electronic hardware, software etc.) via integrated data chains and these links are used, among other things, for monitoring operating conditions and share virtual models in the development cycle, both of which can be visualized via virtual reality. Our virtual reality lab has the CAVE and Powerwall virtual reality technologies and several examples of its application are presented.
