    (Published by Seventh Sense Research Group, 2018) Rami Matarneh; Sotnik, S.; Lyashenko, V.
    In this work, the questions of ball bearings operation and their constructive features are considered. A 3D model of a detail is created as a ball bearing for for The Front Axle Knuckle. With Solid CAD, a finite-element analysis of the developed detail type is implemented. In the SolidWorks Simulation module, a ball bearing deformation analysis was carried out as a result of the 2000 N impact force. Based on the constructed model and the results of the analysis it was found that the support meets the requirements of strength in its application.

    Access Control to Robotic Systems Based on Biometric: The Generalized Model and its Practical Implementation
    (INASS, 2023) Abu-Jassar Amer Tahseen; Attar Hani; Lyashenko, V.; Amer Ayman; Sotnik, S.; Solyman Ahmed
    The paper presents a generalized system's structural scheme and components for monitoring and controlling access to robotic systems based on biometric data for decision-making. Mathematical decision-making models for choosing the best alternative based on fuzzy sets are proposed. The fuzzy analytical hierarchy process determined weights of 6 criteria (for k1 criterion weighting factor is equal to 2.2; for k2 criterion – 1.8; for k3 criterion – 0.6; for k4 criterion – 0.6; for k5 criterion – 0.6; for k6 criterion – 0.2, that is, most weighty would be k1 – recognition accuracy) against which the best option was evaluated. Thus, during evaluation of alternative on six criteria it was obtained that t alternative X1 (face recognition in full-face), will have the key value of embership function of resulting fuzzy set alternatives with ideal value of integral criterion, equal to 0.53, and as result, implemented rational choice, taking into account given criteria. The difference is that we have introduced such criteria as anti-spoofing. The access control system for robotic systems works in real-time. It is implemented based on an algorithmic decision -making complex, which includes two-factor authentication to increase security: registration involves entering emp loyee data from the keyboard (password, login, surname, first name, position) and physiological uthentication (identification by face). Face detection is proposed to be implemented on several images: face, profile, face, and profile in the mask. A distinctive feature of our development is that often, a main requirement for "access control systems with facial identification" is the frontal location of the face relative to the camera; in our case, the image of the face at an angle was added.

    Analysis of electronic locks existing systems
    (ХНУРЕ, 2024) Lvov, A.; Sotnik, S.
    The aim of this work is to develop locking device control system that includes personalization function. Such solution is especially relevant for managers who want to conveniently control attendance of workspaces or restricted areas. Owners of warehouses, archives, laboratories, or ordinary offices often need information about who visits these premises and when, but do not always have ability to obtain such data promptly. The proposed system not only provides this opportunity, but also ensures convenient control through use of modern technologies. This project has created system that, although it has analogues on market, is easy to use and affordable. The study focused on introduction of personalization technology and replacement of traditional keys to open doors using radio frequency identification (RFID), which is already widely used in modern world.

    Analysis of Existing Infliences in Formation of Mobile Robots Trajectory
    (International Journal of Academic Information Systems Research, 2022) Sotnik, S.; Lyashenko, V.
    The work considers and analyzes three main ways of forming trajectory of movement: coordinate trajectory and vector. The choice of description method depends on conditions of specific problem. The specificity of different type’s movement of robots is analyzed: wheeled, tracked and walking. One of features in formation of movement trajectory in space with dynamic obstacles is speed. Thus, analysis of impacts is especially important for those robots that are able to achieve significant speeds and accelerations, as well as for robots characterized by large load capacity, while dynamic effects are associated with significant masses in structural elements. Today, there is no unified universal approach to constructing trajectories in environment with obstacles. The analysis showed that formation of rational trajectory taking into account: length and smoothness of trajectory; nature of workspace an d map of area; safety – distance to obstacles; type of mobile platform (method of moving robot) will ensure correctness and conflict-free trajectory.

    (IJMER, 2018) Lyashenko, V.; Matarneh, Rami; Sotnik, S.
    Plastic products are used in various spheres of human activity. These different directions are determined by the properties of the plastic. Nevertheless, the high quality of plastic products is important. To achieve quality, first of all, it is necessary to avoid defects in the casting of plastic products. We have considered the traditional approaches to the definition of casting defects molded. We also made an overview of the main defects in injection molding. The factors of deformation of plastic products were considered. The analysis of the reasons and ways of elimination of defects of plastic products is carried out. The possibility of considering various defects of plastic products in the form of a generalized binary matrix is shown. A generalized sequence of designing plastic products is proposed.
