Mobile robots are used in more and more applications nowadays. These applications involve the research, but also real-world and industrial niches have been found where these platforms fulfill important tasks. In recent years huge focus has been put on the autonomous operation of mobile robots. However, in many tasks a direct control exerted by a human operator is necessary. These tasks may, for example, include search and rescue operations, or other tasks where human intelligence has not been yet surpassed by the machine intelligence. Furthermore, even in simple and repetitive operations it is very much desired to allow for robot programming with Learning-by-Demonstration approach. Teleoperation is therefore a very important topic. There is an extensive research covering the problem of the Human-Machine interface (HMI) aspect of teleoperation. Numerous devices exist that allow for human control of robotic platforms. These devices offer various advantages and disadvantages that make them suited for different modes of operation. In this work, we focus on implementing a mobile platform teleoperation system with the use of a force-torque sensor. We present the configuration of such system using ROS and compare experimentally the performance of the proposed device with a typicalapproach using joystick control.

Brain-Computer interfaces (BCIs) may open up new possibilities for Virtual Reality (VR) applications: BCIs may be used for active brain control of VR avatars, or to make VR content passively-adaptive based on information decoded from ongoing brain activity. Application domains for such Brain-VR interfaces (BVRI) include medical and healthcare, entertainment, and education. Conversely, VR technology also opens up new possibilities for BCI research and development: E.g., gamified immersive BCI paradigms may improve subject engagement and long-term motivation, helping to study learning and adaptivity in the BCI-control context. Previously, we have demonstrated a first adaptive, deep-learning-based online BCI for the control of robotic assistants. Here, we describe the extension of this setup to a modular, extensible, VR-compatible online BCI setup. We describe how we integrated a classical active BCI control paradigm using motor imagery into a gamified interactive VR scenario, designed to enhance the long-term motivation of subjects. We also present an initial quality assessment of electroencephalographic (EEG) signals acquired with a dry-electrode system. We anticipate that the presented modular adaptive Brain-VR interface will help to understand and facilitate (co-)adaptivity during long-term BCI usage.

This paper proposes an advanced traffic light controlsystem using IoT devices and computer vision, integrated through M2M interactions and modeled with AnyLogic PLE. The key contribution is the combination of IoT and computer vision for real-time, adaptive traffic light control. The study highlights the practical value of M2M technology, facilitating seamless interaction between web camera-equipped traffic lights and personal computers, overcoming the complexity of traditional wired methods like Siemens microcontrollers. Using a socket library for communication between Windows and Linux-based Raspberry Pi, the system implements interactive Wi-Fi information exchange for video monitoring and real-time road situation recognition. These data inputs control traffic lights via computer vision, enabling automated, adaptive traffic management. The prototype demonstrates real-time animated simulation managed by a dispatcher, enhancing the efficiency of traffic systems. The integration of M2M, IoT, and computer vision marks a significant advancement in intelligent transportation systems.

This paper presents the design and implementation of an IoT-based air quality monitoring system in the Jiu Valley, utilizing sensor networks to predict and detect anomalies in air pollution levels. The Jiu Valley, an industrial region with significant mining activities, faces challenges in air quality management and environmental monitoring. To address this, a distributed network of environmental sensors is proposed to measure key air quality parameters such as PM2.5, PM10, nitrogen dioxide (NO 2 ), carbon monoxide (CO), and sulfur dioxide (SO 2 ). These sensors are connected to a central platform via low-power wide-area network technologies, such as LoRaWAN, ensuring reliable data transmission even in remote areas. The system employs advanced data processing techniques, including machine learning algorithms for anomaly detection, and time-series prediction models to forecast air quality levels. Additionally, the system's data will be visualized through an interactive web interface, enabling real-time monitoring and alerts for residents and authorities. The research aims to contribute to a more effective environmental management framework in the Jiu Valley by leveraging IoT and sensor networks to provide actionable insights into air quality trends, allowing for timely interventions.

This paper investigates the potential to leverage existing 5G NR signals for network-side integrated sensing and communications (ISAC). In general, the synchronization signal block (SSB) is a suitable candidate for always-on downlink sensing, due to its frequent periodical availability and because of its beam-sweeping nature. However, as this work demonstrates, using only the SSB has challenges related to radar ambiguity while being also limited in both distance and velocity resolution due to limited bandwidth and per-beam time duration, respectively. A novel solution is then introduced by combining SSB with downlink control information (DCI) and system information block 1 (SIB1) symbols. The corresponding implications and variants how SIB1 is optimized and configured are discussed, covering both 5G evolution and potential 6G solutions. The performance of the proposed approach is also assessed through realistic numerical evaluations at both 3.5GHz and 28 GHz network deployments, and shown to yield up to 25 dB suppression in radar peak sidelobe level (PSL) compared to SSB-only based range-velocity profile. Also considerable improvements in the sensing resolution in the order of 120-190% are demonstrated.
