It conveys to the ground control station (GCS) the image of the person, the global positioning system (GPS) location as well as a thermal image of the hot body detected. The UAV system is equipped with two cameras: an optical camera and a thermal camera. They propose the design of a system capable of detecting coronavirus automatically from the thermal image quickly and with less human interactions using IoT-based drone technology. The study in demonstrates how versatile and fast-growing is the adoption of UAV solutions in daily life scenarios. Red, green, blue (RGB) sensors were the most used, and applications utilised quality video transmission to the ground control station. The review shows that across the world, applications used various multirotor and fixed-wing UAV platforms. Compared to conventional spaceborne or airborne remote sensing platforms, UAVs offer more advantages in terms of data acquisition windows, revisits, sensor types, viewing angles, flying altitudes, and overlap dimensions. In, a review of the most recent applications of UAVs in the cryosphere was conducted. Drone features are determined by specific UAV applications as well as competition in the commercial market.
UAVs technology is rapidly growing while UAV solutions are being proposed at faster rates as various needs arise. The unstable dynamics of the robotic arm, which increase control complexity of UAVs, have widely been studied in the literature. Robotic manipulators, found in many applications, have in recent years been implemented on UAV platforms for tasks such as aerial manipulation, grasping, and cooperative transportation. They are used in many applications such as inspecting pipelines and power lines, surveillance and mapping, military combat, agriculture, delivery of medicines in remote areas, aerial mapping, and many others. Drones are now present in many daily life activities. There has been a rapid development of drones for the past few decades due to the advancement of components such as micro electro-mechanical systems (MEMS) sensors, microprocessors, high energy lithium polymer (LiPo) batteries, as well as more efficient and compact actuators. This paper endeavours to discuss real-time aspects of drones control as well as possible implementation of real-time flight control system to enhance drones performance.Ī drone, also known as unmanned aerial vehicle (UAV), is an aircraft without a human pilot on board. The control of such highly maneuverable vehicles presents challenges such as real-time response, workload management, and complex control. Progress has been made in the development of highly maneuverable drones for applications such as monitoring, aerial mapping, military combat, agriculture, etc. The reviewed materials presented were chosen to highlight drones that are controlled in real time, and to include technologies used in different applications of drones.
This system characteristic is very much desirable for drones that are now required to perform more sophisticated tasks. Systems in real-time control create more deterministic response such that tasks are guaranteed to be completed within a specified time. This paper presents related literature review on drones or unmanned aerial vehicles that are controlled in real-time.
