For these purposes, standard IT technologies are used. An approach to solving such a problem based on various voice recognition systems is considered. Four main speech recognition systems are described. A system for recognizing voice commands for controlling a robot is considered. A distinctive feature of the proposed system is that the system does not require a permanent connection to the Internet, and the autonomous operation of such a system has the advantage of lower requirements for working with it.

Modeling is one of the analysis tools that permits to preliminarily study some objects, methods, or developments at given properties; accordingly, modeling tends to understand the nature of those characteristics and then re-creates an object, process, or phenomenon that has a degree of common relationship. Thus, modeling is the process of reflecting and learning some properties with the aim of further recreating these properties and improving them if necessary. On the investigated model of the 3D model for a small-sized portable portal miller, the selection of individual parts of such a tool is shown and justified. Moreover, a diagram of a conveyable portal edge machine with Computer Numerical Control (CNC) has been generalized and developed. Through investigating the modeling and designing the necessary devices and mechanisms, a variety of systems have been studied to explain the reason for choosing the SolidWorks system for modeling types. The choice of individual components of a small-sized portable portal milling machine is demonstrated and justified using the example of making a 3D model. In addition, a generalized and developed block diagram of a portable portal milling machine with CNC has been created, where each element of such a block diagram is described and a recommended selection is made. Finally, individual components of a portable portal milling machine were modeled with CNC …

Accordingly, this paper compares different types of engines for other Industrial robots (IR) and proposes to put practical criteria based on the mechanical design and its application. It starts from describing the IR choice to explaining the synchronous motor with permanent magnets as a base of the motor choice. Particular attention is paid to the consideration of components and their purpose supported by the creation of the subsequent drawings. SolidWorks system was implemented to obtain expressive and high-quality graphics and three dimensions design. Moreover, the entire Electrical Magnetic Force (EMF) was simulated using the method of variational parameterization. Accordingly, a developed synchronous motor with a built-in permanent magnet is proposed, which is supported by 3D design graphics to evaluate the deformation and margin of the housing and motor shaft safety.The obtained...

In order to carry out binarization license plates, features of existing (LPC) were first analyzed. A review of most well-known classification of binarization methods was carried out, and on basis of analysis, classification was proposed, which will be divided into four general classes, which distinguishes our classification from known ones. A fallback class has also been added. As result, pros and cons of all binarization methods have been determined.

The CNC is implemented in mobile maintenance and repair platforms for remote sensing of the environment where the wild environment may not allow us to access the animals and places. The proposed work in this paper is based on recent research, which shows that applying the automated CNC speeds up the processes of repair, modernizes the equipment size, and significantly reduces the economic costs; accordingly, the authors developed a block diagram of a portable CNC laser engraver. The choice of the hardware was also made, taking into account the possibility of quick replacement in the field, which reduces the repair time and the cost of the developed layout. A control system based on the selected modules was synthesized, and a stability check was carried out using MatLab tools. To check the correctness of the developed control s...
