Building robotic models for the purposes of achieving goals in engineering projects, and its usage as a strategy advantage of such projects, are the main topics of this paper. Also, implementation of innovative technologies, like augmented reality (AR) and internet of things (IoT), on simplified robotic models (SRM) are at the focus in the paper. The authors find that the strategy of building and using SRM concept in complex engineering projects is fully justified, particularly before construction of the real objects that can be very expensive and time consuming. The fact that developed solutions (for example, AR apps) can be transferred to the final objects with necessary testing and modification strongly supports the authors’ standing in this paper. Uniqueness of this work is reflected in the use of LEGO elements for building physical model of a centrifuge for pilot training, according to the project requirements, and developing an AR/IoT mobile app that could be applied to the real centrifuge. In addition to the strategy based on SRM, the authors stress the importance of such AR development strategy.
