Публікація 3D Modeling of the Ball Bearing for the Front Axle Knuckle(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.Публікація 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 AhmedThe 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.Публікація Agricultural Robotic Platforms(IJEAIS, 2022) Sotnik, S.; Lyashenko, V.This overview article discusses latest advances in robotics using example of 2, 4 and 6 finite walking robots applied in various fields.

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.Публікація Analysis of Systems for Development of 3D Models(IJAISR, 2021) Sotnik, S.; Lyashenko, V.; Sinelnikova, T.The article initially discusses Maya and 3Ds Max because to some extent they are systems for developing three-dimensional models.
