In recent years, multirotors have become more and more widely used, such as in aerial photography and delivery. Ensuring a safe landing in emergencies is the most basic requirement, and it is important to make full use of all the sensors of the multirotor. To improve the safety of UAV landing in unknown unstructured scenes, this paper proposes a multi-FOV-constrained trajectory planning algorithm. Due to the discontinuity of multi-FOV constraints and the nonlinearity of UAV dynamics, the entire trajectory planning problem is a nonlinear optimization problem with non-convex constraints. To address this problem, our algorithm contains two stages, a multi-fov-constrained path search algorithm and a safe landing trajectory optimization algorithm. The multi-fov-constrained path search algorithm is used to generate a safe initial path that satisfies the FOV constraint. Then, the safe landing trajectory optimization algorithm generates a safe trajectory, which considers FOV constraints, dynamics, smoothness, and obstacle avoidance. We conducted simulation experiments and real-world experiments to verify the robustness and effectiveness of our algorithm.

The current organizational methods employed in storage facilities and stores are predominantly manual, lacking proper systematic management, particularly in convenience stores where inventory management is often disorganized. The absence of categorization and a systematic approach complicates inventory tracking, leading to unreliability and significant manual labor each time an item needs to be checked or restocked. This challenge is also observed in courier service storage facilities, delivery trucks, and hubs, resulting in a high incidence of missing parcels due to inadequate management. To address these inefficiencies, this research aims to develop an inventory management system that reduces manual labor by implementing Arduino microcontroller technology, NFC stickers/tags, and NFC modules. Additionally, the system leverages PLX-DAQ add-ins to seamlessly export data from the microcontroller into Microsoft Excel, facilitating real-time inventory updates and management. By achieving these objectives, it can save time and labor power, significantly improving the reliability and efficiency of inventory management in both convenience stores and courier service facilities.

Solar power is prominent among the renewable energy sources that the world is moving towards. On the other hand, grid stability and reliability are threatened by solar energy's intermittent nature. To solve this problem, we present a new method in this research that uses smart grids that combine IoT with hedge systems. The suggested system uses Internet of Things (IoT) sensors and actuators to dynamically modify hedge systems in response to changes in solar power generation. The technology maximizes the efficiency of hedge systems by utilizing machine learning algorithms and predictive analytics to reduce the impact of unpredictability on solar power output. As a result, grid stability is improved, and solar power generation reliability is increased.
