The paper describes a method for determining the trajectory of a mobile robot inside a production room among obstacles. To determine the path of movement, a navigation system is used, which determines the robot's own coordinates, plans the trajectory at the current time and controls its movement. A software tool for modeling the behavior of a mobile robot taking into account the properties of its mechatronic platform is proposed. The model of the adaptive control system of the mobile platform is described. The block diagram of the program for modeling the method of finding the optimal way to move a mobile platform among uncertain obstacles is considered. The simulation results are given.

Reducing energy consumption in networks of IoT devices is very important. This paper presents the results of experimental studies of the proposed method of reducing power consumption for the protective gateway of the industrial network. Research was conducted for devices built on Lora modules. The LoRa Modem Calculator software from Semtech was used as a modeling tool. The recommended values of the program registers are given to achieve optimal energy consumption parameters for data reception and transmission modes. Information about the prototype is given and its practical implementation is shown. The developed prototype of the gateway implements the ?Protocol Transformation? method, which allows removing possible dangerous inserts from the data packets received by the gateway. This can improve the security of packets from the gateway to IoT devices and back, and thus the network as a whole.

“…To solve the problem of optimization of movement time along a given manipulator trajectory, it is necessary not only to accurately estimate the speed of manipulator nodes, but also to provide a linear characteristic of estimating the position of the mechanism in a wide range of speed changes. It is also important to determine the absolute angular position of manipulator design elements, especially in the interaction of industrial automation objects using the Internet of Things technology [7][8][9][10][11]. Thus, the study of methods for determining the position of structural elements of the manipulator at any point in time is an urgent task.…”

In the field of mechatronic systems, manipulators are often used for automated assembly of products, welding, painting parts and more. An important task is to optimize the travel time along a given trajectory of the manipulator. To solve this problem, it is necessary not only to accurately estimate the speed of the manipulator nodes, but also to provide a linear characteristic of the assessment of the position of the mechanism in a wide range of speeds. The matter of the article are methods for determining the orientation of the joint of the manipulator. The goal of the work is to develop a module for determining the orientation of the joint of the manipulator and study its operation in order to determine the suitability subject of the structure for practical use. The following tasks are solved in the article: to investigate the principles of determining the orientation of the joints of industrial robots; choose the design of the orientation determination module; develop an algorithm for determining the position of the joint at any time; perform experimental studies of the position determination module in order to confirm the suitability of the structure for practical use. The following methods used are: experimental research was conducted on a real object - a model of the manipulator joint, created using methods and tools of 3D prototyping; to determine the position of the joint of the manipulator used methods of processing signals received from sensors; processing of experimental results and calculation of values of errors of positioning of a joint of the manipulator is based on methods of the statistical analysis of random sizes. The following results were obtained: the principles of determining the orientation of the joints of industrial robots were studied; the design is developed and the module of definition of orientation of a joint of the manipulator is created; developed an algorithm for determining the position of the joint at any time; the suitability of the design for practical use has been experimentally confirmed. Conclusions: in this paper, two variants of the sensor design are proposed to determine the absolute angle of rotation of the manipulator joint: resistive and magnetic. The proposed design of the resistive sensor was non-technological and much larger than the design of the magnetic sensor. The data obtained in the process of conducting experimental studies of the proposed method of measuring the angle of rotation of the mechanical gearbox of the manipulator joint indicate a fairly accurate determination of the angle using a magnetic sensor. The calculated measurement error was less than 1.4 degrees. The results of the experiment also showed that in addition to the radial direction of movement of the gearbox of the manipulator joint there is a significant displacement along the working plane, and in some cases, such displacements are chaotic. This is due to some defects and imperfections of the surface of the manufactured parts of the joint model used in research.
