The paper presents project and its verification of a prototype integrated circuit containing an analog, programmable finite impulse response (FIR) filter, implemented in CMOS 350 nm technology. The structure of the filter is based on the switched capacitor technique. In circuits of this type, one of main challenges is an efficient implementation of filter coefficients, which result from several factors described in this work. When implementing such filters as programmable circuits, the values of their coefficients have to be limited to a selected range, i.e. a given resolution in bits. In the implemented prototype filter, the filter coefficients are represented by 6 bits in sign-magnitude notation, so they can take 63 different values only. In such filters, it is not possible to directly implement any frequency response of the filter. Each time, it is necessary to properly round the theoretical values of the coefficients so that they fit into the available range of discrete values resulting from the implementation. The authors of the work designed an algorithm that allows such matching. The paper also presents results of measurements of the prototype chip. © 2023 Division of Signal Processing and Electronic Systems, Poznan University of Technology (DSPES PUT).

In recent years, due to the rapid development of computer vision technology, real-time detection and tracking of objects using computer vision has become a hot topic. Object detection mainly consists of two parts: object segmentation and object recognition, that is, object acquisition. Accurate detection of targets is the key to achieving high-precision and high-efficiency tracking. Based on the above discussion, this article explored the target detection and tracking of survey robots using the multimodal Internet of Things (IoT) sensor data fusion of YOLOv5, and compared and analyzed the performance of direct frame difference method, traditional ORB method, and the algorithm in this paper through experiments. The results indicated that the accuracy and recall of the robot image object detection algorithm proposed in this paper were both above 90%, and higher than other algorithms, indicating that the algorithm has extremely high accuracy in object detection. © 2024 IEEE.

This paper presents an original detection system for measuring the speed of vehicles on a road used in the laboratory for educational and testing purposes. Although the maximum speed limit is specified for each type of road, accidents still occur due to unjustified exceeding of speed limits. Therefore, it was found that these problems could be solved with the help of electronic circuits. Thus, the paper presents the development of an original educational system for detecting the speed of a road vehicle, which consists of an Arduino UNO Rev3 microcontroller, two infrared sensors, a 1602A LCD and an electronic system specially used for the intelligent braking of the vehicle, using for this a wireless communication system. The entire original system will be integrated into an autonomous safety vehicle system. © 2022, Cefin Publishing House. All rights reserved.

Remote controllability, real-time response, and small size are critically requirement of medical devices operated in blind, unstructured, and fluidic environments of biomedical regions. Untethered swimming soft milli-robots have been developed to fulfill treatment and therapy in such that region under magnetic navigation. The soft robot's motor-less mechanism with a high-DOF utilizes magnetic compliance of the deformable structure with a minimal control of oscillating magnetic field. Theoretically, magnetic property of the robots is defined by magnetic moments consisting of orientation and strength. Orientation can be programmed by magnetizing technique, and strength is defined by quantity of magnetic moments in the structure. Herein, this work investigates how orientation and quantity of magnetic moments affect swimming behavior and performance of the robots. The soft robots are designed into three distinguish types of magnetic property embedded in the deformable structure;the I-robot has non-uniform magnetic orientation and uniform magnetic strength, the II-robot has uniform magnetic orientation and non-uniform magnetic strength, and the III-robot has non-uniform magnetic orientation and non-uniform magnetic strength. The results interestingly report that each type of robot's property functions mechanism and benefits swimming performance differently under the same control parameters. The I-robot does not have any exceptional potential, but the II-robot can be operated at the higher control frequency even reaching the step-out point. The III-robot shows the greatest performance in swimming and maneuverability. These results are useful to design a swimming soft-robot capable of applying for various purposes, especially when the demand concerns non-harm, small-scale, soft-interface, and remote controllability. © 2023 IEEE.

This paper investigates the problem of trajectory planning for autonomous vehicles at unsignalized intersections, specifically focusing on scenarios where the vehicle lacks the right of way and yet must cross safely. To address this issue, we have employed a method based on the Partially Observable Markov Decision Processes (POMDPs) framework designed for planning under uncertainty. The method utilizes the Adaptive Belief Tree (ABT) algorithm as an approximate solver for the POMDPs. We outline the POMDP formulation, beginning with discretizing the intersection's topology. Additionally, we present a dynamics model for the prediction of the evolving states of vehicles, such as their position and velocity. Using an observation model, we also describe the connection of those states with the imperfect (noisy) available measurements. Our results confirmed that the method is able to plan collision-free trajectories in a series of simulations utilizing real-world traffic data from aerial footage of two distinct intersections. Furthermore, we studied the impact of parameter adjustments of the ABT algorithm on the method's performance. This provides guidance in determining reasonable parameter settings, which is valuable for future method applications. Copyright © 2024 by SCITEPRESS - Science and Technology Publications, Lda.

作者： MICHLOWICZ, Edward AGH University of Science and Technology Faculty of Mechanical Engineering and Robotics Poland

The number of IT systems and technologies supporting various processes, including the manufacturing, has been growing in recent years. Various versions of integrated ERP-class systems are known. At the same time, we are in the fourth indus-trial revolution. The future is Industry 4.0 and Digital Factory. Industry 4.0 is an overall term for technical innovations and value change organization concepts which revolutionize the industrial production. Currently, the digital technologies change the way production is carried out by generating, transferring and processing of data, and also by analysing large amounts of datasets. There is a problem of the place and significance of logistics, transport and supply chains in the fourth industrial revolution. What is logistics engineering, what methods are suggested to solve the contemporary problems of logistic support of production processes? To whom are the virtual systems dedicated? What rules should be applied by small and medium enterprises (SME)? Is the pressure of virtual world a threat to such companies? Is it possible to design and make real products without virtual manufacturing? Hence, does Logistics 4.0 exist and where is it used? The practice of logistics engineering is applied during the entire system lifecycle by means of interactive processes supporting the anal-yses and research (compromise) for optimization of costs, logistics and efficiency. Surely, it can be said that without the correctly designed and effective logistic processes the contemporary production system could not achieve the required productivity and effectiveness. The article describes the basic tasks of logistics engineering in relation to production com-panies, as well as relations with Industry 4.0. and digital factory. Moreover, a proposal of the author's own algorithms for use in the quest to improve the continuity of flow and of enterprise effectiveness for SME class companies was presented. © 2021 Warsaw University of Technology.

There are some people who has sixths finger and they can do some task that needs both hands by one hand. Moreover, There are many wearable hand they are difficult to use by beginner. Therefore, in this study, we developed a Robotic Sixth Finger as a lightweight and easy-to-wear wearable robot. In this study, we focused on the key-striking action of a piano and aimed to play a novel musical instrument using the robotic sixth finger. The robotic sixth finger was developed using a 3D printer. Experiments were then conducted to evaluate the response speed of the Electro-Magnetic Generator EMG input and its usability. The biological signal that operated the robotic sixth finger was an electromyogram of the extensor carpi ulnaris muscle of the left arm. Five healthy female subjects aged (18-24) years participated in the experiment. The SUS (System Usability Scale) index as a subjective evaluation and the reaction time between the robotic sixth finger and other fingers as an objective evaluation were measured. The SUS index was (70.5±6.47) points, and the reaction time was (0.56±0.12) seconds. These results indicate that the device can be used intuitively, although there is a slight time delay in terms of keystroke movement. © 2024 IEEE.
