The article discusses the main provisions and the role of mechatronics in production in agriculture. A review of current and promising mechatronic systems for use in agriculture is carried out. It is noted that the use of scientific and technological advances in the field of mechatronics opens up new opportunities for solving multidisciplinary problems, and also makes a person dependent on technical means. The current state and world trends in the application and development of mechatronic systems in the field of agricultural production are investigated. The needs for the use of mechatronic systems and modules in the conditions of agricultural enterprises are analyzed and the problems associated with their implementation and use are identified. The purpose of creating such complexes is to achieve a combination of high productivity and at the same time flexibility of the technical and technological environment due to the possibility of its reconfiguration, which will ensure the competitiveness and high quality of products in world markets. In modern mechatronic systems, to ensure a high quality of implementation of complex and precise movements, it is necessary to apply intelligent control methods. To create intelligent systems, it is necessary to provide flexible interaction of components within the system and with the outside world. Current trends in the use of mechatronic systems and modules in agricultural production are determined. As the scope of application of mechatronic systems expands and international scientific and technical relations expand, it becomes more and more important to actively exchange new production and information technologies between their creators and users, between various groups of consumers and developers (research centers, enterprises of various forms of ownership, universities ). These forms of cooperation are implemented within the framework of international technology transfer. The development of mechatronics as an interdisciplinary scientific and technical field, in addition to obvious technical and technological difficulties, also raises a number of new organizational and economic problems.

The aim of the paper is to determine the scale of agricultural land conversion in gmina (municipalities) located in selected metropolitan areas of Poland. Analyses were conducted taking into account the location of agricultural land in relation to the core of metropolitan area and its suitability for agricultural production. The research has shown that in the metropolitan areas selected for analysis, agricultural land conversion in the period 1996–2014 was over twice as fast as the average for Poland, with the most land converted in the core of a metropolitan area, little less in the first zone of gmina around the core, and the least in gmina located on the outskirts of a metropolitan area. The hypothesis saying that the distance of a gmina from the core of the metropolitan area is a significant factor in the differences in conversion processes, and high quality of environmental conditions of agricultural production does not limit (in a significant way) the process of farmland abandonment has been positively verified.

Intelligent systems are driven by the latest technological advances in so different areas as sensing, embedded systems, wireless communications or context recognition. This paper focuses on some of those areas. Concretely, the paper deals with wireless communications issues on embedded systems. More precisely, the paper combines the multi-hop networking with Bluetooth technology and a quality of service (QoS) metric, the latency. Bluetooth is a radio license free worldwide communication standard that makes low power multi-hop wireless networking available. It establishes piconets (point-to-point and point-to-multipoint links) and scatternets (multi-hop networks). As a result, many Bluetooth nodes can be interconnected to set up ambient intelligent networks. Then, this paper presents the results of the investigation on multi-hop latency with park and sniff Bluetooth low power modes conducted over the hardware test bench previously implemented. In addition, the empirical models to estimate the latency of multi-hop communications over Bluetooth Asynchronous Connectionless Links (ACL) in park and sniff mode are given. The designers of devices and networks for intelligent systems will benefit from the estimation of the latency in Bluetooth multi-hop communications that the models provide.

In Fused deposition modeling (FDM) process, there has been a confliction between high productivity and high quality of products. The product resolution is proportional to the flow rate of heated material extrusion, which directly affects the build time. To reduce the build time with acceptable resolution, the idea of parameter adjustable printing process has been introduced. The controllable extruder was modified and two types of diameter changeable nozzle have been designed. This work realizes different resolution building based on the part geometry during FDM process, which can efficiently assure the quality of products and improve the productivity at the same time.

With increasing in size of glass substrates for flat panel, both high productivity and high quality are required for its edge rounding process. In order to understand the effect of process speed on the strength of glass substrate, this study performs a profile grinding at the substrate edge with varied feed rate. The obtained glass substrate then undergoes a four-point bending to evaluate its strength. Weibull distribution is used to analyze the fracture strength of glass substrate after edge-rounding process and to correlate the removal rate with the quality of the process.

Sowing is affected by numerous factors, and thus high‑quality sowing is a very important task for agricultural engineers and managers of profitable agricultural production. The primary purpose of sowing is placing seeds at proper depths and in‑row spacings in well‑prepared soil. Plant population particularly gives prominence to sowing as it directly affects the uniformity of plant growth and development. Soybean planting is especially dependent on the quality of planting for yield formation due to the significant vicinity of seeds. Provided all external factors of high‑quality sowing are met, i.e. sowing conditions, the quality of sowing depends upon the planting mechanism. The following features of the planting mechanism are the most important: RPM of the seed disc, the travel speed of a seeder, and the values of gauge and vacuum pressure. This paper presents the results of sowing three different fractions of soybean seeds under laboratory conditions. The quality measurement of sowing was performed at different values of vacuum pressure and RPM of the seed disc. On balance, an increase in vacuum pressure results in improved sowing quality due to a stronger adherence of seeds to the seed disc. Lower values of vacuum pressure do not exert significant effects on the quality of sowing, regardless of the seed fraction. However, higher RPM of the seed disc entail an increase in the coefficient of variation. On the basis of the results obtained, a mathematical model for predicting changes in the coefficient of variation of sowing quality was developed using different operating parameters.

A mandatory requirement for the concept of intelligent systems and of digital or cyber-physical twins is the availability of high-quality data. Therefore, the authors investigate the possibility to integrate sensors, actuators and information technologies in standardized machine elements such as screws, bearings and couplings. In this paper, the focus is on sensing machine elements, which are a sub-category of mechatronic machine elements. To gain insights about those in development as well as to verify and validate their functionality, prototypes are needed. Those prototypes should help the designer to gain knowledge about the product in development and they should preferably be developed with low efforts. Therefore, a method is proposed to analyse concepts of mechatronic machine elements, especially sensing machine elements, regarding critical aspects that may interfere with the functionality of the product. The method is based on analysing the flow of the signal that is used for the measurement, starting from its mechanical origin and ending at the analysis unit. Different examples of sensing machine elements are given in this article and the respective flow of the usable signal is analysed, leading to the identification of subsystems that can be tested individually. Based on this, prototypes for the subsystems are developed and introduced.
