This paper proposes a mixed-integer linear programming optimization model used to define an energy management system tailored for nanogrids in buildings, integrating renewable energy sources, battery energy storage systems and task-executing autonomous mobile robots. Focused on a nanogrid to be realised at the Savona Campus of the University of Genoa, the energy management system optimizes power flows and robot task scheduling in order to minimize the operating costs, the curtailment of the photovoltaic source and the number of unperformed tasks. Its novelty lies in combining energy and task planning constraints, offering significant potential for sustainable building energy management.

Traditional farming methods have undergone a substantial operational paradigm shift as a result of the integration of the Internet of Things (IoT) and Unmanned Aerial Vehicles (UAV) systems, which go beyond simple technological advancement. This is because the use of UAVs and IoT recently offers farmers a substantial chance to raise output, strengthen decision-making, and accomplish more sustainability in their operations. The integration of UAVs and the IoT in dairy farming to improve operational efficiency and health monitoring is the focus of this paper. The paper addresses how these technologies could be used to transform dairy production by offering up-to-date information for health monitoring and decision-making. In order to improve operational effectiveness and health monitoring, The paper proposed a system in which IoT sensors on cattle gather health data, which is subsequently sent to UAVs for aerial surveillance and intervention. The goal of the project is to improve farm output and animal welfare by utilizing UAV capabilities and contemporary data analytics to respond quickly to health issues. It tackles issues like energy efficiency and data synchronization in UAVs and offers solutions for smooth technological integration. The study advances efficient and sustainable dairy farming practices by illustrating how the integration of IoT and UAVs might result in precision farming. By expanding the horizons of agricultural technology integration, this work not only proposes a viable solution to contemporary farming challenges but also sets the stage for future innovations in the agricultural sector © 2024, The Authors.

This study examines solar water pumping systems with programmable logic controllers (PLCs) to fill a gap in the literature. PLC-based automation can improve these systems’ reliability and efficiency. However, PLC integration with sensors, actuators, and pumps, power consumption optimization, maintenance, and cost-effectiveness prevent their broad implementation. This work analyses two configurations: a DC-DC boost converter-based MPPT solar water pump control scheme and a thorough PLC-based water pumping component research. A well-designed DC-DC boost converter provides motor voltage. This MATLAB-supported method uses solar panels and pumps to solve water scarcity and conserve energy in developing nations.

Microgrids generally offer a promising and scalable means of providing clean, reliable and affordable energy for consumers in pursuit of Sustainable Development Goal 7 (SDG 7) of United Nations. However, sustainable microgrids operation depends on a number of factors ranging from technical to non-technical hence, the operation and sustainability of microgrids could be quite challenging. To enhance the sustainable operation of microgrids, the traditional approach is to cater for it at the design stage by overrating the design or design for complementary system. However, this approach is cost-intensive and does not perform optimally. Hence, the use of optimization techniques has been recently employed to enhance energy efficiency, reduce costs and improve reliability. The choice of optimization technique for a particular microgrid operation varies depending on the nature, types and configuration of the microgrid. This study therefore examines various microgrid configurations and the optimization techniques currently used for optimal and sustainable operation of microgrids. The study also provides future directions for micro gridsystem designer and operators to equip them with requisite information on the optimization technique for different applications. This study further pursues the realization of SDG 7 through energy sufficiency obtainable from sustainable operation of microgrid systems and will serve as a guide for microgrid system planners and operators. © 2024 IEEE.

In this paper, verification of the efficiency increase of the regulated motor drive with Permanent Magnet Synchronous Machine (PMSM) was performed, using a supercapacitor as an energy storage unit. The supercapacitor is connected to the inverter's DC bus via a three-level DC/DC converter. The supercapacitor is intended to accumulate energy when the drive is in generator mode and to supply the drive while in motor mode. In this way, the application of a bidirectional back-to-back converter for grid connection is not required and a diode rectifier can be used instead. The increased efficiency of a solution with supercapacitor-based energy storage is verified by comparison to low-cost alternatives with a braking chopper. Solutions utilizing supercapacitor storage units significantly reduce the power consumption from the grid. © 2023 IEEE.

The emerging disaster situations within buildup areas due to the collapsing of buildings and tunnels due to bombardments, and natural disasters require immediate rescue missions to save the lives affected, however, the volatile environment poses a huge threat to the rescuers. Furthermore, the aforesaid situation also hinders the surveillance and detection capability. This work is focused on the development of a snake robot with natural side winding rectilinear and serpentine motion to assist rescuers in surveillance and detection of affected within rubbles and ruins. The snake robot, which is composed of numerous series of elastic actuators, utilizes a modular structure to flexibly comply with demanding conditions. Within the snake robot’s 10 joints, an unequal or odd number of series elastic actuators are utilized. We take into account various factors such as size, weight, power, and speed as tradeoffs. Each standalone module consists of a geared servo motor, a bearing, and a series elastic actuator, along with custom electronics that integrate sensors. We also developed the infra-red camera-equipped head and tail modules of the robot, as well as the software program responsible for coordinating the aforementioned motion. Furthermore, we validated and the simulation for both the open-loop and closed-loop control environments. The testing of the prototype in different real-world surface conditions was carried out with successful results.

As the usage of electric vehicles grows in popularity, the risk of accidents caused by them is also drastically increased. High speed, drink-driving, distracting thoughts, overstress, and malfunctioning electronic gadgets, over the temperature in charging are the leading causes of accidents & fire. Also, in electric battery-operated cars, if the battery charging mechanism is not properly thermally stabilized, the battery may catch fire. As a result, the proposed system deals with accident detection systems that occur as a result of a driver's carelessness or system failure while operating an electric vehicle. Proposed Device created with a cardiac sensor in the seat belt and vehicle along with battery temperature, vibration & accelerometer sensors which can help to analyze the vehicle's yaw, roll, pitch, and slip motions. All of the data collected is a synced to ESP-32 controller through IoT-based cloud storage analysis to notify a neighboring helpline center about the accident. This data is also utilized in an AI-based model to detect one of the sovereign sources of death in growing countries i.e., cardiovascular disease, and it's cited by several throughout the globe.
