Autonomous Recharging and Flight Mission Planning for Battery-operated Autonomous Drones

Autonomous drones (also known as unmanned aerial vehicles) are increasingly popular for diverse applications of light-weight delivery and as substitutions of manned operations in remote locations. The computing systems for drones are becoming a new venue for research in cyber-physical systems. Autonomous drones require integrated intelligent decision systems to control and manage their flight missions in the absence of human operators. One of the most crucial aspects of drone mission control and management is related to the optimization of battery lifetime. Typical drones are powered by on-board batteries, with limited capacity. But drones are expected to carry out long missions. Thus, a fully automated management system that can optimize the operations of battery-operated autonomous drones to extend their operation time is highly desirable. This paper presents several contributions to automated management systems for battery-operated drones: (1) We conduct empirical studies to model the battery performance of drones, considering various flight scenarios. (2) We study a joint problem of flight mission planning and recharging optimization for drones with an objective to complete a tour mission for a set of sites of interest in the shortest time. This problem captures diverse applications of delivery and remote operations by drones. (3) We present algorithms for solving the problem of flight mission planning and recharging optimization. We implemented our algorithms in a drone management system, which supports real-time flight path tracking and re-computation in dynamic environments. We evaluated the results of our algorithms using data from empirical studies. (4) To allow fully autonomous recharging of drones, we also develop a robotic charging system prototype that can recharge drones autonomously by our drone management system

Cities and Drones: What Cities Need to Know about Unmanned Aerial Vehicles (UAVs)

NLC's municipal guide, Cities and Drones, is designed to serve as a primer on drones for local officials, providing insight into the recently released federal rules relating to drone operation, as well as offering suggestions for how local governments can craft their own drone ordinances to encourage innovation while also protecting their cities.Drones have the potential to revolutionize many industries and city services, particularly as their technology advances. There are many applications for drones within the public sector at the local and state level. Drones can be used for law enforcement and firefighting, as rural ambulances, and for inspections, environmental monitoring, and disaster management. Any commercial arena that involves outdoor photography or visual inspection will likely be experimenting with drones in the near future, as will retailers who want to speed up package delivery.However, drones also present challenges. There are some safety issues, for instance, when operators fly their drones over people or near planes. City residents often have privacy concerns when any small device hovering nearby could potentially be taking photos or video. The FAA's final rule on drones left some opportunity for city governments to legislate on this issue. Rather than ban them outright, city officials should consider how this new technology might serve residents or enhance city services

Drones and the Fourth Amendment: Redefining Expectations of Privacy

Drones have gained notoriety as a weapon against foreign terrorist targets; yet, they have also recently made headlines as an instrument for domestic surveillance. With their sophisticated capabilities and continuously decreasing costs, it is not surprising that drones have attracted numerous consumers—most notably, law enforcement. Courts will likely soon have to decipher the limits on the government’s use of drones under the Fourth Amendment. But it is unclear where, or even whether, drones would fall under the current jurisprudence. Because of their diverse and sophisticated designs and capabilities, drones might be able to maneuver through the Fourth Amendment’s doctrinal loopholes. This Note advocates analyzing drones under an adapted approach to the reasonable-expectation-of-privacy test in Katz v. United States. Courts should focus more on the test’s oft-neglected first prong—whether a person exhibited a subjective expectation of privacy—and analyze what information falls within the scope of that expectation, excluding information knowingly exposed to the plain view of the public. This analysis also considers instances when, although a subjective expectation exists, it may be impossible or implausible to reasonably exhibit that expectation, a dilemma especially relevant to an analysis of drones. Courts that adopt the recommended analysis would have a coherent and comprehensible approach to factually dynamic cases challenging the constitutionality of drone surveillance. Until then, the constitutional uncertainties of these cases will likely linger

Usage and acceptance of drone technology in healthcare : exploring patients and physicians perspective

Modern technologies such as virtual reality, robots or drones are getting more and more important for organizations. Accordingly, the question arises in which industries these technologies can make a difference. This paper examines the use of drones in Swiss hospitals. A literature review is conducted outlining the most relevant flied of application for drone usage in healthcare. These use cases are then qualitatively rated by employees and patients of hospitals from different regions in Switzerland. Among others, the analysis revealed that employees and patients have strong concerns about drone usage in the hospital environment in the case drones provide diagnosis capabilities, but show less doubts if drones are used for delivery processes
