    摘要： Methods and associated systems for autonomous package delivery utilize a UAS/UAV, an infrared positioning senor, and a docking station integrated with a package delivery vehicle. The UAS/UAV accepts a package for delivery from the docking station on the delivery vehicle and uploads the delivery destination. The UAS/UAV autonomously launches from its docked position on the delivery vehicle. The UAS/UAV autonomously flies to the delivery destination by means of GPS navigation. The UAS/UAV is guided in final delivery by means of a human supervised live video feed from the UAS/UAV. The UAS/UAV is assisted in the descent and delivery of the parcel by precision sensors and if necessary by means of remote human control. The UAS/UAV autonomously returns to the delivery vehicle by means of GPS navigation and precision sensors. The UAS/UAV autonomously docks with the delivery vehicle for recharging and preparation for the next delivery sequence.

    摘要： An unmanned aerial vehicle according to certain embodiments generally includes a chassis, a power supply mounted to the chassis, a control system operable to receive power from the power supply, at least one rotor operable to generate lift under control of the control system, and a motor operable to lower a free end of a line. The free end of the line is operable to engage a parcel to be delivered by the unmanned aerial vehicle. The control system is configured to operate the motor to cause the free end of the line to accelerate toward a delivery surface as the free end of the line passes through a first portion of a distance between the unmanned aerial vehicle and the delivery surface, and to decelerate as the free end of the line passes through a lower portion of the distance.

    摘要： Certain embodiments of the present application relate to a method for releasing a parcel from an unmanned aerial vehicle (UAV). The parcel is engaged with a hook attached to a line suspended from the UAV. The method includes lowering the hook such that the parcel is at least partially supported by a target surface, thereby performing an attempt to release the parcel from the hook, performing at least one iteration of an iterative procedure. The iterative procedure includes raising the hook, and determining whether the line remains loaded. The iterative procedure further includes lowering the hook an additional time in response to a determination that the line remains loaded, thereby performing an additional attempt to release the parcel from the hook. The iterative procedure further includes performing an additional iteration of the iterative procedure in response to the number of attempts failing to satisfy a threshold number of attempts.
