Overall, these components and functionalities collectively enable the UAV to fly autonomously and perform various tasks effectively.
Can AI be implemented in UAVs?5 answersAI can be implemented in UAVs to enable onboard processing of extensive AI tasks for remote sensing applications. This can be achieved through edge computing, where the edge is responsible for processing AI tasks and the cloud is responsible for data storage and manipulation. By using AI methods such as deep neural networks (DNNs), UAVs can provide additional computation capabilities for ground IoT devices, improving efficiency and lifestyles. Edge AI, which runs AI on-device or on edge servers close to users, is suitable for improving UAV-based IoT services, as it ensures low latency and low energy consumption. The implementation of edge AI in UAVs has a significant impact on various technical aspects, including autonomous navigation, power management, computer vision, and communication, as well as applications such as delivery systems, precision agriculture, and search and rescue operations.
How can we design real-time monitoring and communication for UAVs?5 answersReal-time monitoring and communication for UAVs can be designed using a combination of technologies. One approach is to optimize the trajectory design of UAVs to serve as both downlink transmitters and radar receivers, allowing for real-time tracking and prediction of the UAV's location based on delay measurements extracted from sensing echoes. Another approach is to combine UAV technology with modern 4/5G communication network technology, adopting key technologies such as multi-base station relay, antenna optimization, and PTZ measurement and control to ensure real-time and remote interaction needs. Additionally, the integration of software-defined network (SDN) and digital twin (DT) technology can provide real-time monitoring, analysis, and virtualization of network performance, revolutionizing the design, implementation, and maintenance of software-defined UAV networks.
How can we design a regulations and guidelines for UAVs?5 answersRegulations and guidelines for UAVs can be designed by considering the specific application and measurement target, as well as the assessment of measurement uncertainty. It is important to address key challenges such as privacy, safety, security, public nuisance, and trespass, and compare existing regulations against criteria to identify any shortfalls. Additionally, the design of guidance laws based on robust feedback linearization concepts can ensure autonomous pursuit of predefined waypoints for UAVs, taking into account external disturbances such as wind gusts. The development of appropriate national legislation is crucial, particularly for distinguishing between hobbyist and commercial use of UAVs, and ensuring the responsibility of the pilot for any accidents or incidents. It is also important to align UAV regulations with the specific needs and applications of a country, such as precision agriculture, forestry, and topographical surveying, to facilitate the efficient use of UAVs and promote overall development.
What are UAVs?3 answersUnmanned Aerial Vehicles (UAVs), also known as drones, are flying vehicles that can operate without a human pilot onboard. They can be controlled remotely or fly autonomously using a flight plan. UAVs are equipped with various sensors such as cameras, IMUs, LiDAR, and GPS to collect and transmit real-time data. They have gained widespread interest in both civilian and military applications, including precision agriculture, search and rescue, wireless communications, surveillance, and military purposes. UAVs have different specifications in terms of size, weight, range, endurance, engine type, and configuration. They face challenges such as collision avoidance, battery life, and security. UAVs have been integrated into IoT systems, enabling applications in various domains such as industrial, agricultural, smart homes, smart cities, and smart transportation.
