Abstract:
This paper has proposed a program analysis method over the current state of the workspace of an anthropomorphic manipulator using the Mathcad software application package (USA). The analysis of the manipulator workspace helped solve the following sub-tasks: to calculate the limits of the grip reach, to determine the presence of "dead zones" within the manipulator workspace, to build the boundaries of the manipulator workspace. A kinematic scheme of the manipulator typically provides for at least five degrees of mobility, which is why in the three-dimensional Cartesian coordinate system the wor

Abstract:
This article substantiates the possibility of increasing the level of mechanization of assembly and welding production of shipyards by introducing multifunctional complex mechanized assembly and welding manipulators. The idea is substantiated that such a manipulator, initially having relatively small functionality, but the projected possibility of a gradual increase and complication of functions, can contribute to an increase in the level of mechanization of production, up to its complete robotization. It is concluded that the creation of such equipment already at this stage will increase the

Abstract:
Information communications networks, and especially their industrial versions (field networks), are an inseparable element of contemporary control systems. They enable pieces of modern industrial equipment to be coupled into a common system. In the case of older-generation equipment (universal one-stand CNC machine tools, manipulators, robots), their extension and integration in either dispersed or centralized control system is possible. As a result of modernization, it is possible to create a production line that will be built based on classic CNC machine tools and operated by manipulators or

Abstract:
With the quest for modernization in robotics motion control of robot manipulators is an area of active research. In motion control, inverse trajectory application is the most adopted solution which is further improved by considering the effect of external forces of the environment. The impact of external force involves dynamic modelling of the system and force control, impedance control, and admittance control techniques are adopted for the solution. This research implements the simulation and more precise visualization of the real-life manipulator under the rules of kinematics and dynamics on

The method of modernization of industrial robots due to the use of synchronous servo electric motors with a digital control system has been given. The digital control system can be arranged either on the basis of the controller, or with the use of a computer. The method of calculation of the digital regulator parameters to get the set indicators of control quality has been received. The use of digital controllers makes it possible not only to improve the control quality, but also to increase the margin of stability.

Robotic systems play an important role in the development and modernization processes of production, facilitation of labor, and human life. The robotic manipulators are outstanding among such systems. Such robots can be used for various spheres of their application. In this case, there is the manipulator’s effective control problem in the working area, of which there may be various obstacles. Therefore, a procedure is required to find the optimal path for moving the robotic arm.

The briefest of moments are subjected to exhausting descriptions of scene and movement even as whole periods and epochs are compressed into a single clause or sentence. These manipulations of narrative time let Faulkner’s fiction pose a set of questions about how fast or slow history takes place. The chapter links Faulkner’s first months working as a screenwriter in Hollywood to the final production and publication of Light in August, a novel that features some of his most explicit ref

As part of the TPP Kostolac A, since the first synchronization of its unit A1 in 1967, coal delivery system has been operating, the task of which is to receive, store and deliver coal for the operation of TPPs in Kostolac. With the construction of unit A2 in 1980, an increased consumption of coal occurred, as well as a demand for more stable and reliable operation of the units, which led to the construction of a 6.3 kV switchgear in 2002. After its exploitation and continuous operation, the reconstruction and modernization of the 6.3 kV switchgear was carried out in 2023. There were no more sp
