This article deals with experiences with the development of applications of the ESP32 microcontrollers and provides a comprehensive review of the possibilities of applications development on this platform in the area of data measurement and processing. Microcontrollers usually connect with IoT modules and other smart sensors and provide data to the superior system. This paper also describes implementation of application with the version of connected OLED display and with ESP32 Wrover development board with integrated display.

The benefits and opportunities of using virtual reality (VR) in education have been the subject of research for several decades. Descriptions of individual VR applications can be found in the literature, but there is no structured analysis of these applications on the market. This study analyses the market of VR educational applications in 2019 - 2021 in addition to monitoring development trends in their offerings, content and parameters. This study aims to map the VR applications that teachers currently have available to include as part of the learning process. Another goal was to analyse the user evaluation of VR educational applications and compile an overview of them, to see which applications users appreciate the most. The results indicated that more than half of the sample applications are available free of charge, they mostly use English as the communication language and users’ best rated applications are from the areas connected to nature, space, medicine, art and history.

The usage of tablet and mobile devices has growing potencial. The fragmented mobile landscape presents considerable challenges around application development. The key element for publishing software applications in Apple's iOS or Google's Android operating system is to build them with software development kit. HTML5 web apps are emerging as an alternative. This paper deals with available frameworks, cross-platform solutions, mobile development tools, summary of mechanical engineering apps and development of mobile dictionary of the English-Czech automatic control terms.

Virtual reality technologies for supporting teaching and learning have been an academic research topic for decades. In the last five years, major progress have been made and the virtual reality technology is getting closer to being implemented in education. This paper presents an overview of the uses of virtual reality in education, specifically on the Oculus Rift platform. The purpose of this study is to explore the current use of virtual reality to support teaching and learning. The results of the study show what is the distribution of curriculum content in virtual reality applications and what are the best users' rated educational virtual reality applications.

The paper describes the design and realization of the mobile application for the Android operating system which is focused on manual control of mobile robot using wireless Bluetooth technology. The application allows the robot control interaction with the display, or voice. When we use a graphical interface, we can monitor the current distance of the robot from obstacles. The measurement of distance is carried out by ultrasonic sensor placed in front of the robot. It was necessary to build a prototype of a mobile robot for the development of the application. The prototype of the mobile robot is based on the differential gear.
