(Черкаського національного університету імені Богдана Хмельницького, 2023) Yevsieiev, V.; Demska, N.
However, reducing the mass of the manipulator should not lead to a loss of its strength parameters. If the manipulator is not able to withstand the load, it may break during operation, which may lead to the failure of the entire robot, as well as create a danger to the surrounding people. Thus, the study of the possibility of reducing the mass of the manipulator without losing its strength parameters is an urgent task, which will allow to increase the efficiency of mobile manipulative robots and reduce the costs of their operation, while not impairing the safety of the robot.

Development of a 3D Model of a Manipulator for Mobile Robotic Platforms Based on Unigraphics NX
(Видавничий дім «Гельветика», 2022) Nevliudov, I.; Yevsieiev, V.; Demska, N.; Valkivskyi, Y.
The article discusses the issues of modernization of the mobile robot Festo Robotino, due to the integration of the MR-999E manipulator system into it. This solution will significantly expand the functionality of the mobile robot Festo Robotino and will allow for new research related to the development of new methods and models for making decisions on moving objects. Based on the study, it was revealed that the existing MR-999E manipulator system has a number of disadvantages, one of which is the insufficient compression force of the gripper to move the test objects, which does not allow it to be widely implemented as a mobile manipulation platform. To eliminate these shortcomings, the authors carried out research, on the basis of which a kinematic diagram of the gripping module was developed. To check the correctness of the decisions made and the obtained calculations in the CAD Unigraphics NX system, 3D models of all the main elements of the mobile manipulator were developed, the dimensions of the teeth with an involute profile were calculated, which made it possible to increase the positioning accuracy of the links in space to solve the problem of spatial assembly of structures with the required accuracy. Based on the developed 3D models, the authors have designed a detailed 3D model of the manipulator assembly, in the CAD Unigraphics NX system, as well as using numerical engineering analysis, based on the finite element method, calculations were carried out to determine the required gripping force of the improved gripping mechanism. The developed 3D models are made using additive 3D printing technologies. This made it possible to manufacture a prototype of the gripping mechanism and experimentally confirm the possibility of integrating it with the Festo Robotino mobile robot in order to expand its functionality.

The subject of research in the article is production management processes based on cyber-physical systems. The purpose of the work is to automate the management of production processes using the cybernetic component and analyze the results. To achieve this goal, it is necessary to solve the following tasks: develop an analytical and logical model of the CPPS development management process taking into account the requirements specified in the terms of reference for the development CPPS; to present the analytical and logical structure of connections in the form of a model of interaction of the main windows and all the necessary graphical elements for the implementation of the full-featured interface of the developed CPPS; to carry out experimental researches of efficiency and practical approbation of the received theoretical results, by comparison of classical methods and the developed ones. Results: The targets, physical and cybernetic components of the CPPS development management process were combined in a single information space from the beginning of development to its implementation. The process of checking the achievement of the main goal of CPPS evelopment has been automated, which makes it possible to make changes and manage the CPPS development process at any level and stage of the proposed technology. The process of managing the development of the cybernetic component is automated on the basis of synthesized algorithms of functioning using the GUI elements of object-oriented programming languages, which made it possible to increase the flexibility of the proposed architecture and technologies for automating the CPPS development process and to reduce the development time of the cybernetic component. Conclusions: the proposed models and methods will not only automate the process of managing the development of CPPS from scratch, but will also make it possible to automate the process of managing the development of the cybernetic component for the modernization and improvement of existing CPPS.

(Hindawi, 2022) Abu-Jassar, Amer Tahseen; Attar, Hani; Yevsieiev, V.; Amer, Ayman; Demska, N.; Luhach, Ashish Kr.; Lyashenko, V.
This paper discusses the development of new hardware and software for protecting access to HMI/SCADA systems via Unprotected Internet Networks (UPN), mainly when working remotely with confidential information. Based on the analysis carried out, it is shown that the existing vulnerabilities can be exploited by cybercriminals to steal passwords and user authentication logins. Modern protection technologies based on the OTP method have been investigated. Moreover, a new concept of information security for user authentication in UPNs when working with information remotely is proposed. The structure of the electronic key and the connection diagram based on the selected hardware modules have been developed. In addition, the two-level user identification algorithms and the firmware program code for the ATmega32U4 microcontroller are considered. Finally, to show the reliability and stability of the of the developed electronic user authentication key against any unexpected software hacking, a number of experiments have been performed.

(ХНУРЕ, 2019) Nevliudov, I.; Demska, N.; Starodubcev, N. ; Nevliudova, V.
Modern technologies move away from the traditional design of hard electronics into the form factors of flexible switching structures, which are often operated in a dynamic mode and can be subjected to such actions as alternating loads, bending and twisting, stretching, vibration, the presence of a chemically aggressive environment, etc. Despite a large number of existing studies using an arsenal of achievements in the field of materials science, means of classical and quantum physics, the theory of chemical reactions, statistical physics, fracture mechanics, up to date, some essential phenomena occurring at the atomic-molecular level during the implementation of the manufacturing process and design of flexible structures have not been fully disclosed. In this paper, we consider the processes of the appearance in the materials and structures of connectors of products of physicochemical reactions associated with the presence of two sources of medium formation, which are interpreted as the formation in a certain place, over a certain period of time, of a substance with new properties, the appearance of which can cause degradation processes. As a result, the obtained dependences, together with the statistical processing of the obtained information, can provide a sufficient description of the process for its optimal control, even under conditions of incomplete certainty about the subtle mechanisms of atomic-molecular interaction between the materials involved in the process.

(2021) Nevliudov, I.; Yevsieiev, V.; Demska, N.; Valkivskyi, Y.
Modern production is impossible without the introduction of advanced technologies, which are reflected in the concept of the fourth industrial revolution Industry 4.0. The proposed concept affects all areas of production processes, through the introduction of cyber-physical production systems (CPPS), robotic systems (RS), artificial intelligence (AI), the use of Industrial Internet of Things (IIoT) and the desire for full automation of all technological processes (TP). This approach to the implementation of production processes allows to solve a number of complex problems: optimization and automation of TP, obtaining data on the implementation of TP in real time, collecting analytical information for monitoring and forecasting, which will allow to fulfill the requirements of Lean Manufacturing (LM). To solve these problems, it is necessary to create a single information environment, based on IIoT, which would cover all stages of production management. This requires that all equipment be part of a single information space of the enterprise, for which it is necessary to replace obsolete equipment with new one with the support of digital control systems, which leads to large financial losses. In this regard, many companies are considering the task of upgrading existing equipment. The solution of this problem is a complex scientific and technical problem, the solution of which covers the following areas: the theory of automatic control, circuitry, programming. One of the difficult objects to upgrade is a robot manipulator. This article discusses some aspects of solving the problem of modernization of the robot control system manipulator PUMA-560 (PM-01). The study of actuators, PM-01 engines and control cabinet Puma Mark III (Sphere-36 (56)), developed a structural control scheme PUMA-560 lower level. The element base is analyzed, the microprocessor is chosen and the circuit diagram is designed. Using EDA Altium Designer, a printed circuit board for the PUMA-560 manipulator control system was developed with the ability to connect to modern microcomputers, such as LattePanda, running Windows 10/11. The proposed solution, according to the authors, will automate the control system of the manipulator PUMA-560 and connect it to a single information network based on IIoT.

(ХНУРЕ, 2021) Osadchy, S.; Demska, N.; Oleksandrov, Yu.; Nevliudova, V.
The development of cyber-physical production systems is a complex scientific and technical task, therefore the developer needs to determine the requirements, tasks for the system being developed and choose an architectural model for its implementation. In turn, the choice of an architectural model assumes a balance for the set of requirements of persons interested in its development. In a typical case, the development of a specific cyber-physical industrial systems needs to be adapted to the means of implementation, to the realities of its future use, maintenance and evolution. Subject matter of this study are architectural models for building complex cyber-physical production systems. Goal of this article is a study of architectural models DIKW and 5C, according to the results of the decomposition of which, in the future, it will be possible to carry out a mathematical description of elementary problems of each level and their physical or simulation modeling. To achieve this goal, it is necessary to solve the following tasks: analyze the DIKW model; analyze the architectural model 5C; compare the DIKW model and the 5C architectural model, using its structural decomposition into levels, information and command channels with feedback within each structure. The research carried out is based on the methods of decomposition and formalized representation of systems. Conclusions: Based on the results of the decomposition at each structural level of the DIKW and 5C models, a decomposition structure was developed, which shows the main differences and general similarities of the models. It was revealed that the 5C model, as a common software shell that combines integrated sensors and actuators, is more suitable for solving problems of developing a cyber-physical production system, and the DIKW interpretation model is more suitable for solving problems of modifying existing systems at enterprises, and the choice of the model itself the development of a cyber-physical production system depends on the requirements of the customer, existing equipment, the level of its automation and the level of project financing.
