The various types of applications for arm robots have made it one of the most important topics within the field. An important step to be considered is the application of a suitable control algorithm that takes into account the complex nonlinear dynamics. However, nonlinear control methods can still face difficulties due to the complexity of implementation. In this paper, four degrees of freedom (4-DOF) robot arm model is considered. Simple linear control methods are proposed to be used in the control of the angle of robotjoints. For this purpose, the fuzzy logic controller (FLC) and the two degree of freedom PID (2-DOF PID) controller are applied to control the joint angles of robot arm and in order to improve the response speed and reduce overshoot. The system simulation was performed using the MATLAB/Simulink software package. Simulation results show that the FLC has a faster response with a better rise time compared to the 2-DOF PID controller. © 2021 IEEE.

In trajectory optimization, Model Predictive Path Integral (MPPI) control is a sampling-based Model Predictive Control (MPC) framework that generates optimal inputs by efficiently simulating numerous trajectories. In practice, however, MPPI often struggles to guarantee safety assurance and balance efficient sampling in open spaces with the need for more extensive exploration under tight constraints. To address this challenge, we incorporate discrete barrier states (DBaS) into MPPI and propose a novel MPPI-DBaS algorithm that ensures system safety and enables adaptive exploration across diverse scenarios. We evaluate our method in simulation experiments where the vehicle navigates through closely placed obstacles. The results demonstrate that the proposed algorithm significantly outperforms standard MPPI, achieving a higher success rate and lower tracking errors. © 2025, CC BY.

The desired development and design of an electric control system (ECS) for a precision planter is one of the most crucial elements in evaluating the efficacy of applicators for plant production. The seeds would be sown using this approach. Years have been invested in the continuous development of a range of application methods and metering systems, each of which offers specific advantages for applying the required system with a high degree of precision. Researchers worldwide have been trying to make electric-driven seed meters (EDSM) for planters, but they haven't succeeded. This study looks into the current state of installing seed metering systems for precision planters. Proportional-integral (PI) and sliding mode control (SMC) designs of the control system have been implemented to improve the planting quality of the planters. We want to highlight the electrically driven control system (EDCS) using these designs. An overview of the noteworthy features and limitations of past research is given. We also discuss several future directions for future research, concentrating on the knowledge gaps in this area.

The behavioral modelling of mechatronic systems through the Digital Twin concept represents an advanced methodology for their design and optimization. A Digital Twin creates a dynamic virtual model that accurately reflects the real-time behavior of the physical system, enabling the analysis and simulation of various operational scenarios. Siemens NX is a comprehensive design and simulation tool, offering extensive capabilities for developing and testing mechanical, electronic, and software components in a virtual environment. This integration empowers designers to examine the complex interactions among subsystems, reducing risks and enhancing performance from the initial design stages. Digital models, empowered by the potential of Digital Twin technology, not only predict dynamic system behavior and identify potential defects but also enable real-time monitoring and continuous updates of the digital twin based on data collected from actual systems. This technology holds the promise of enhancing the energy efficiency, reliability, and longevity of mechatronic systems. The combination of Digital Twin technology and Siemens NX fosters the development of intelligent, customized solutions that address intricate requirements in fields such as advanced manufacturing, industrial automation, and autonomous transportation, inspiring a future of optimized and efficient systems. This article explores these capabilities by presenting two applications: integrating a robotic structure within a conveyor system and integrating a robot for servicing a machine tool. In conclusion, the synergy of these two technologies establishes a working algorithm that users must follow when designing and operating mechatronic systems while also outlining the advantages and disadvantages of this approach.

Tillage of the soil is the most important consideration when it comes to the implementation of agricultural practices. Increases in crop yield has been achieved through a variety of agricultural practices thanks to the discoveries of various agricultural experts. The planting process is the one that has the greatest impact on the crop's overall health. The hull can be more precisely prepared for the seed-planting trench with the assistance of furrows. A variety of furrow openers are currently undergoing the implantation process. Studying dynamic systems that are discontinuous in nature can be done with the help of discrete element modelling. The simulation of a tine-shaped furrow opener using the EDEM package software was carried out for three different speeds. When the speed of an object increases, so does the force it exerts on it. Additionally, the length of an object has an effect on the force it exerts. Additionally, taken into consideration were the profiles that were generated in the soil. To carry out statistical validation of the results analysis of variation (ANOVA) was done. The results provided a basis for calculating a confidence level of 95%. For the furrow openers, it was suggested that a speed of 0.495 meters per second, which is equivalent to 1.76 kilometers per hour, be used.

This paper presents a new dataset for Kazakh-Russian Sign Language (KRSL) created for the purposes of Sign Language Processing. In 2020, Kazakhstan's schools were quickly switched to online mode due to COVID-19 pandemic. Every working day, the El-arna TV channel was broadcasting video lessons for grades from 1 to 11 with sign language translation. This opportunity allowed us to record a corpus with a large vocabulary and spontaneous SL interpretation. To this end, this corpus contains video recordings of Kazakhstan's online school translated to Kazakh-Russian sign language by 7 interpreters. At the moment we collected and cleaned 890 hours of video material. A custom annotation tool was created to make the process of data annotation simple and easy-to-use by Deaf community. To date, around 325 hours of videos have been annotated with glosses and 4,009 lessons out of 4,547 were transcribed with automatic speech-to-text software. KRSL-OnlineSchool dataset will be made publicly available at https://***/online-school/. © European Language Resources Association (ELRA), licensed under CC-BY-NC 4.0.

Liver vessel segmentation is important in diagnosing and treating liver diseases. Iodine-based contrast agents are typically used to improve liver vessel segmentation by enhancing vascular structure contrast. However, conventional computed tomography (CT) is still limited with low contrast due to energy-integrating detectors. Photon counting detector-based computed tomography (PCD-CT) shows the high vascular structure contrast in CT images using multi-energy information, thereby allowing accurate liver vessel segmentation. In this paper, we propose a deep learning-based liver vessel segmentation method which takes advantages of the multi-energy information from PCD-CT. We develop a 3D UNet to segment vascular structures within the liver from 4 multi-energy bin images which separates iodine contrast agents. The experimental results on simulated abdominal phantom dataset demonstrated that our proposed method for the PCD-CT outperformed the standard deep learning segmentation method with conventional CT in terms of dice overlap score and 3D vascular structure visualization. © 2022 SPIE.
