“…From the above mentioned results, it is observed that the proposed system performs well in the outdoor environment and successfully operates and maintains a desired position for precise landing operation over the charging station. Unlike [4,5,9,11], in which precise positioning and landing tasks are performed indoors using precise position feedback from motion capture systems, the proposed solution utilizes GPS for localizing itself generally over the landing target and uses an onboard camera for precise tracking and positioning over the landing platform. The proposed solution in this research provides the suitable control for conducting wireless charging operation in outdoor environments extending the concept of autonomous wireless charging of UAVs proposed in [3] for indoor environments.…”

“…One major drawback of contact-based charging is the requirement of precise landing on the charging station and the mechanical system in order to strongly bond the electrodes for the conductivity, which eventually increases the control complexity and cost. Furthermore, it requires mm accuracy positioning, which is a challenge due to the unavailability of precise localization system in outdoor environments [11].…”

Rotary-wing unmanned aerial vehicles (UAVs) have the ability to operate in confined spaces and to hover over point of interest, but they have limited flight time and endurance. Conventional contact-based charging system for UAVs has been used, but it requires high landing accuracy for proper docking. Instead of the conventional system, autonomous wireless battery charging system for UAVs in outdoor conditions is proposed in this paper. UAVs can be wirelessly charged using the proposed charging system, regardless of yaw angle between UAVs and wireless charging pad, which can further reduce their control complexity for autonomous landing. The increased overall mission time eventually relaxes the limitations on payload and flight time. In this paper, a cost effective automatic recharging solution for UAVs in outdoor environments is proposed using wireless power transfer (WPT). This research proposes a global positioning system (GPS) and vision-based closed-loop target detection and a tracking system for precise landing of quadcopters in outdoor environments. The system uses the onboard camera to detect the shape, color and position of the defined target in image frame. Based on the offset of the target from the center of the image frame, control commands are generated to track and maintain the center position. Commercially available AR.Drone. was used to demonstrate the proposed concept which is equppied with bottom camera and GPS. Experiments and analyses showed good performance, and about 75% average WPT efficiency was achieved in this research.

A major limitation of existing battery-powered quadrotor UAVs is their reduced flight endurance. To address this issue, by leveraging the electrical model of a brushless DC motor, we explicitly determine minimum-energy paths between a predefined initial and final configuration of a quadrotor by solving an optimal control problem with respect to the angular accelerations of the four propellers. As a variation on this problem, if the total energy consumption between two boundary states is fixed, minimum-time and/or minimumcontrol-effort trajectories are computed for the aerial vehicle. The theory is illustrated for the DJI Phantom 2 quadrotor in three realistic scenarios.

“…Massachusetts institute of technology researchers [16] and ETH Zurich have developed an independent contact recharge station for UAVs. This charge solution involves contact with mechanical electrodes and the UAV must land on an accurate manner on the charging station, which ultimately increases the control complexity and therefore affects the costs of the entire system [27]. The system utilizes a Vicon Camera System which provides precise UAV and ground station position information, However, we should recognize that the Vicon Camera System cannot be used outside and that, instead, GPS sensors should be used despite inherent position mistakes [28].…”

An efficient charging station is a necessity for Unmanned Aerial Vehicle (UAV) systems. However, if that implementation adds more complexity and onboard weight, then that exercise becomes a burden rather than a benefit since UAV's engineers aim to improve efficiency by reducing the energy consumed by the software and hardware of the complete aeronautical system. This article recommends a fully automatic contact charging station for UAVs, which can charge UAVs and thus resolve flight endurance restrictions of the UAV. The ground station consists of square copper plates that are positively and negatively polarized successively in a chessboard with particular sizes to guarantee electric contact at the landing. The design methodology used with the loading station takes into account the differences in UAV orientation once the platform has landed. In addition, this innovation uses independent charging after touchdown. Thus, this technology relaxes common flight times and help to enhance general mission times. This paper presents a unique charging platform in a "chessboard" configuration, which is devised as an interconnecting interface to facilitate the charging process and overcome inaccuracies with the landing. The solution devised in this research requires few components and presents two power source options (solar & mains power). Additionally, this work presents, to the best of our knowledge, a uniquely innovative recharging landing platform, which incidentally requires no additional software or changes to the UAV's onboard software settings.
