“…Compared to multi-rotor systems, Single rotor drones have higher endurance with longer flights and can carry heavier payloads to perform a variety of tasks [122], and they are often powered by gas engines [123]. Much like the multirotor UAVs, single rotor drones are also suitable for aerial photography [124] in addition to spraying agricultural crops [121], [125]. Although the use of single rotor drones for agricultural plant protection has been greatly appreciated, various shortcomings still exist in this field.…”

The use of drones, formally known as unmanned aerial vehicles (UAVs), has significantly increased across a variety of applications over the past few years. This is due to the rapid advancement towards the design and production of inexpensive and dependable UAVs and the growing request for the utilization of such platforms particularly in civil applications. With their intrinsic attributes such as high mobility, rapid deployment and flexible altitude, UAVs have the potential to be utilized in many wireless system applications. On the one hand, UAVs are able to operate as flying mobile terminals within wireless/cellular networks to support a variety of missions such as goods delivery, search and rescue, precision agriculture monitoring, and remote sensing. On the other hand, UAVs can be utilized as aerial base stations to increase wireless communication coverage, reliability, and the capacity of wireless systems without additional investment in wireless systems infrastructure. The aim of this article is to review the current applications of UAVs for civil and commercial purposes. The focus of this paper is on the challenges and communication requirements associated with UAV-based communication systems. This article initially classifies UAVs in terms of various parameters, some of which can impact UAVs' communication performance. It then provides an overview of aerial networking and investigates UAVs routing protocols specifically, which are considered as one of the challenges in UAV communication. This article later investigates the use of UAV networks in a variety of civil applications and considers many challenges and communication demands of these applications. Subsequently, different types of simulation platforms are investigated from a communication and networking viewpoint. Finally, it identifies areas of future research.

“…The development of control, propulsion, power supply components, and other subsystems has contributed to greater speed of data processing and greater autonomy, which enables the performance of complex flight missions. The development of propulsion components and numerous studies of propulsion configurations have facilitated applications in various sectors, such as precision agriculture [1,2], surveillance [3], and aerial photography [4]. The application possibilities of UAVs are plentiful in many other sectors, such as transport [5], construction [6], fire protection [7], and more.…”

Trends and Opportunities of Rapid Prototyping Technologies

View full text Add to dashboard Cite

Rapid prototyping technologies have enabled a major step forward in the development of a very wide range of products, especially in the field of mechatronic systems. These technologies are largely related to additive manufacturing (AM), so-called 3D printing which is, in addition to product development, also suitable for the fabrication of mechatronic systems that are not intended for series production. In this chapter, a framework for the AM of specialised multirotor unmanned aerial vehicles (UAVs) parts is proposed and described for three AM technologies—fused deposition modelling (FDM), selective laser sintering (SLS), and stereolithography (SLA). A different approach to parts design is shown where the main problems are addressed and guidelines for parts manufacturing are given. Special emphasis is related to the mechanical characteristics and low weight of the manufactured parts that are merged with carbon fibre segments. The manufactured (printed) parts are mounted in functional assemblies and preliminarily tested.

“…dog barking, tiger roaring, thunder, helicopter) have been proposed, although cattle appear to habituate to sound signals only (Butler et al 2006). For mustering without a need for devices on animals, there is increasing interest in the possibility of using drones that play aversive sounds and that are themselves, perceived as a threat to the animals to stimulate moving away from the aerial vehicle (Gordon et al 2018;Yinka-Banjo and Ajayi 2019). Other aversive stimuli emanating from drones such as an olfactory cue have been proposed to prod the animals in the desired direction (Gordon et al 2018) but the research on the use of drones for herding is currently limited (Yinka-Banjo and Ajayi 2019).…”

The application of virtual fencing technology effectively herds cattle and sheep

Context. Herding and mustering procedures during livestock management can be time-consuming, labour intensive, and costly. The ability to gather animals virtually is an enticing notion but technology to do this is not widely commercially available.Aims. The eShepherd ® virtual fencing system being developed for cattle may be able to remotely herd animals. This system operates via global positioning system, and requires animals to wear a neckband device. Animals are trained to associate an audio tone with an electrical pulse to avoid a virtual boundary.Methods. Experiments were conducted with cattle using pre-commercial prototypes of the automated virtual fencing neckbands, and with sheep using manually operated dog training collars implementing the same virtual fencing algorithm to explore the potential of this technology for herding, and optimal fence designs for herding success. In the first experiment, five groups of 12 cattle were moved down a 344 m paddock using three different fence placement designs.Results. The most successful design for cattle herding was a back fence that followed behind the animals to prevent them from turning back in the wrong direction. The fences were manually activated by personnel based on the cattle movement. The same type of fence design was manually applied to two groups of six sheep to successfully herd them down a 140 m paddock in the second experiment.Conclusions. All herding was highly dependent on the animal's own pace of movement as no signals were applied to 'push' the animals, the systems only prevented movement back in the wrong direction. The pre-commercial prototype of the automated eShepherd ® device used is now obsolete and testing with updated versions would be needed to confirm its application for animal herding.Implications. These preliminary trials indicate potential for virtual fencing technology to herd livestock, but technology improvements are required, and an automated device for sheep is not yet available.
