“…drones not only can operate in natural disasters rescuing, heavy snowfalls, and strong winds searching, but also can locate building firefighters, police, hostage, suspects, and terrorist in a building or a room [136]. Since the implementation of drone technology, drones have exhibited the capability to capture detailed images and search large areas, cooperate with other drones [137][138][139][140], and have autonomous flight within an indoor environment [141]. Schnieders et al [142] evaluated a single drone to assist law enforcement agencies in a simulated building clearance operation to address the interior dangers of law-enforcement clearing operations.…”

“…Joshuah K. Stolaroff et al [139] showed that although drones consume less energy per package-km than delivery trucks, the additional warehouse energy required and the longer distances traveled by drones per package significantly increase the life-cycle impacts. Govindarajan and Sridharan estimated the sizing and performance of four VTOL configurations, which are being used in package delivery missions [140]. A gradient-based optimization approach was used to determine the optimum designs for each configuration under each weight class.…”

During the past two decades, with the advancement of avionics, control systems, design, product methods, and communication systems, UAVs have gained more interest from both civil and military customers. Hence, more researchers have dedicated their time to developing new applications for drones and improving their performance. In this study, a literature review on drone applications is conducted. It is explained that they can be more effective and beneficial when merged with preexisting systems, and thus making a system of systems. Further, we have classified UAV applications more comprehensively. This classification can be very useful for providing insights when designing new UAVs. Finally, previous works are discussed thoroughly and diagrams are developed to show the research focus in this field. These statistical diagrams can also be used as a gap analysis tool.

“…The design of it considers various factors such as the size and weight of parcels, accessibility, and safety of parcels. Table 2 shows some of the delivery UAVs that are currently available and the payload that they can carry [4]. To further explain, payload is defined as the weight that an UAV can carry.…”

Unmanned Aerial Vehicle or UAV has evolved rapidly because of improved regulations and advancement in technology. During the COVID-19 pandemic, delivery UAVs were utilized more often than ever to deliver medical supplies, as well as parcels. Delivery UAVs work by collecting the goods and keeping it in a designated holder, which it then navigates through an area and dropping it off at the receiving point. The main factors that are considered for the design of a delivery UAV mechanism includes size and weight of parcels, security and the efficiency of loading and unloading parcels. The drop-box mechanism takes in the factors contributing to existing delivery UAV mechanisms and provides a solution that can overcome most of these concerns. The mechanism was designed through SOLIDWORKS software and 3D-printed. With the help of SOLIDWORKS, an analysis was performed, and it was concluded that the mechanism could handle a maximum of 2kg. Aside from that, the mechanism drops off parcels automatically and encourages contactless delivery.

“…While Swarnkar et al present a 6-DOF (degree of freedom) flight dynamics model and dynamic inversion based nonlinear controller for all modes of biplane quadrotor [46]. Govindarajan et al present a conceptual sizing and performance valuation of four VTOL configurations to conclude that wing-borne designs like the quadrotor biplane and tricopter are capable of quickly delivering packages [47]. In this paper, we designed backstepping controller for trajectory tracking and an adaptive backstepping controller for a scenario where we drop 6 kg weight at location a, and pick up 3 kg weight each from locations b and c, while reducing altitude by only 2 m, and maintaining 20 m height to get back to the original location.…”

Performance of the UAVs for a particular application can be enhanced by hybrid design, where take-off, hover, and landing happen like rotary-wing UAVs, and flies like fixed-wing UAVs. A backstepping controller and an adaptive backstepping controller are designed for trajectory tracking and payload delivery in a medical emergency or medical substance delivery like vaccine delivery in the presence of wind gust. Simulation results show that the backstepping controller effectively tracks the trajectory during the entire flight envelope, including take-off, hovering, the transition phase, level flight mode, and landing. A comparison between Backstepping, Integral Terminal Sliding Mode (ITSMC) and Adaptive Backstepping controllers for payload delivery show that the adaptive backstepping controller effectively tracks the altitude and attitude. ITSMC is capable of tracking the desired trajectory for a change in the mass but has sluggish response. The backstepping controller generates a steady-state error in altitude during the mass change in biplane quadrotor.
