Abstract: The goal of this study is to build a self-driving robot that can effectively navigate mazes by utilizing sophisticated computer vision algorithms with ROS2. Fusion 360 is used to create the robot model, and ROS2 launch files are used to initialize the sensor and control nodes. Attaining optimal path planning and accurate localization are the main objectives. The combination of novel motion planning based on the orientation of the robot with graph search algorithms like DFS, A*, and Dijkstra's leads to effective maze discovery and traversal. Thorough testing shows that the system can successfully navigate unfamiliar maze configurations, demonstrating the dependability of ROS2 and modern robotics techniques. By completing this study, a foundation for future advancements in perception and planning to manage more complex settings is laid.

Abstract: As for the case with many other emerging industries, certain shortage of water causes mechanical devices to shut down. In addition to that, some instruments need a controlled water supply to run efficiently. On the other hand, many SMEs suffer from unnecessary power consumption, which can be controlled by a SCADA system. In a country like Bangladesh, where most of the labor is uneducated, it is essential to have a dominance of computers to command for machinery remotely. In this study, A PI controller-based water supply System is designed using a programming logic controller (Siemens s7-1200), HMI (Siemens KTP basic 400), and factory IO 3D environment. The priority-based SCADA System has been introduced for the SMEs (Small and medium Enterprises) using the ladder logic, which will be useful for controlled power consumption.

Abstract: In this study, a low-cost industrial SCADA system has been presented and being developed for SMEs (small and medium companies). As is the case with many other emerging economies, such as Bangladesh, several SMEs contribute to the country's economy. Commercial SCADA systems, which are available in the market, are costly to set up and maintain for smaller companies. Also, the controlling and data acquisition interface of the loads through software has to be developed, which is also costly. As a result, keeping the cost-cut of the small companies in mind, those SCADA systems cannot be used in general. So, a low-cost SCADA system prototype has been designed for SMEs. In this paper, two microcontrollers have been used for faster data acquisition and better performance for logic switching of loads by minimizing the switching delay.

Abstract: Renewable energy sources are the power of the present. Carbon dioxide (CO2) emissions from fossil fuel burning considerably contribute to global warming. The plan is to generate power with vertical axis wind turbines that will be coupled to a smart microgrid system. This system will transfer solar and wind energy into electrical energy utilizing solar panels and wind turbines. An Arduino UNO will supply all data from the solar panel and wind turbine. The system will be linked to an intelligent microgrid, which will allow for continuous power delivery. If the fault detector detects a problem with the system, SMS messages will be delivered via a GSM modem. This technology will make power generation and delivery easier. MATLAB/SIMULINK will be used to construct and test this system. In addition, a power monitoring system based on the Internet of Things (IoT) is implemented and utilized to collect and analyze data on electrical characteristics such as voltage, current, active power, and load energy usage. The Internet of Things (IoT) application ‘Thing Speak’ is used to collect real-time electrical data from users.

Abstract: Providing space for both power plants and agriculture can be a significant difficulty for densely populated nations with limited land. In this paper, transparent photovoltaic (PV) panels are utilized to construct a solar power plant that can simultaneously produce electricity to the national grid and serve as land for agriculture, as sunlight can penetrate through transparent PV panels. This will allow the system to generate electricity in frames land without harming the agriculture. In addition to enhancing agricultural output, agro-photovoltaic adds to the provision of off-grid power in developing and rural regions. For enhancing the protection of the system Directional Over current relay (DOCR) is used for analyzing the faults. To connect the power plant in the load, the hardware specifications of transparent PV panels, boost converters, inverters, and transformers is reviewed in depth.

Abstract-Rapid population growth has resulted in haphazard approaches to managing solid waste in various cities and metropolitan regions, which in turn has led to an increase in the number of illnesses and difficult circumstances. Many people in Bangladesh have already put up with a significant amount of discomfort caused by issues with waste disposal. The authors proposed a sustainable solution to remedy this using an Arduino-driven device that would be able to properly sort waste and garbage by using the sensor that we incorporated into our device, and it would finish by measuring the weight of recyclable and non-recyclable trash at the end of the process. This apparatus can sort rubbish utilizing metal sensors, infrared proximity sensors, and barcode scanners, and it can also sort garbage into recyclable and non-recyclable categories. In order to execute the system, the body work is completed in AutoCAD, and the simulation of the system is carried out in Proteus. Finally, the system has been fully developed with all of the components required to perform the appropriate output analyses.

Abstract-This study shows a prototype for detecting lung effects using microwave imaging. Continuous monitoring of pulmonary fluid levels is one of the most successful approaches for detecting fluid in the lung; early Chest X-rays, computational tomography (CT)-scans, and magnetic resonance imaging (MRI) are the most commonly used instruments for fluid detection. Nonetheless, they lack sensitivity to ionizing radiation and are inaccessible to the general public. This research focuses on the development of a low-cost, portable, and noninvasive device for detecting Covid-19 or lung damage. The simulation of the system involved the antenna design, a 3D model of the human lung, the building of a COMSOL model, and image processing to estimate the lung damage percentage. The simulation consisted of three components. The primary element requires mode switching for four array antennas (transmit and receive). In the paper, microwave tomography was used. Using microwave near-field imaging, the second component of the simulation analyses the lung's bioheat and electromagnetic waves as well as examines the image creation under various conditions; many electromagnetic factors seen at the receiving device are investigated. The final phase of the simulation shows the affected area of the lung phantom and the extent of the damage.
