A Drive-through Recharging Strategy for a Quadrotor

AutoCharge: Autonomous Charging for Perpetual Quadrotor Missions

“…As a result, tethered charging solutions are not portable. The authors in [18] propose a charging system that uses onboard sensing to attach a tether with a pair of loose hooks mid-flight. However, this method is not orientation-agnostic because the pair of hooks must match the station's polarity, requires precise control to localize and grasp the tether, and the loose tether attachment limits the quadrotor's ability to roll and pitch to avoid detachment.…”

“…Various solutions have been proposed for extending the flight time of quadrotors, from battery expansion and battery replacement methods [2]- [7], wireless charging [8]- [11], contact charging [12]- [15], and tethered charging [16]- [18]. However, these approaches do not meet all the requirements of the ideal autonomous charging system for quadrotors, but trade-off efficiency, portability, universality, and robustness.…”

Droneport: From Concept To Simulation

“…One option to keep the drone operational is to recharge the battery, which can be done automatically without human involvement [5,11]. However, that solution requires the drone to remain on the ground for long periods of time and results in blocking the charging station for other drones.…”
