A payload retrieval apparatus including a support structure having an upper end and a lower end; a first sloped surface secured to the support structure and a second sloped surface positioned adjacent the first sloped surface; an opening between the first and second sloped surfaces leading to a space to allow a payload retriever attached to a tether suspended from a UAV to travel into the space; an angled channel positioned beneath the first sloped surface having a tether slot to allow for passage of the tether as the payload retriever is drawn through the angled channel; and a payload holder positioned at the end of the angled channel.

A payload retrieval apparatus having a base, an autoloader assembly mounted to the base including: a payload holder configured to hold a payload for retrieval by a UAV, a channel coupled to the payload holder configured to direct a payload retriever suspended from the UAV to the payload holder, and a locking feature configured to lock access to the payload on the payload holder that includes has a movable end that extends through a wall of the channel into an interior of the channel, wherein when the payload retriever contacts the movable end of the locking member, the movable end moves outwardly thereby unlocking the payload on the payload holder, wherein the payload holder is positioned such that when the payload retriever exits the channel, the payload retriever engages a handle of the payload and removes the payload from the payload holder.

A payload retrieval apparatus having a base, an extending member secured to the base, the extending member including a lower section that is attached to the base and an upper section coupled to the lower section and movable between a first lowered position and a second raised position, an autoloader assembly mounted to the upper section of the extending member, the autoloader assembly including a payload holder configured to hold a payload for retrieval by an uncrewed aerial vehicle (UAV), a channel coupled to the payload holder and configured to direct a payload coupling apparatus to the payload holder, and a first tether engager that extends away from the channel in a first direction, wherein the first tether engager is adapted to guide a tether having a first end attached to the UAV and a second end attached to the payload coupling apparatus towards the payload holder.

A combination payload retrieval and package pickup apparatus having a base, an autoloader assembly mounted to the base including a payload holder configured to hold a payload for retrieval by a UAV, a channel coupled to the payload holder and configured to direct a payload coupling apparatus to the payload holder, a package receptacle housing having package receptacles configured to house a package to be picked up, wherein each of the package receptacles includes a locking feature to secure a package to be picked up in the package receptacle, wherein the locking feature is configured to be unlocked upon receipt of a first access code to allow access to an interior of the package receptacle to allow a package to be placed into, or removed from, the package receptacle.

A payload retrieval apparatus having an extending member having an upper end and a lower end, a channel having a first end and a second end and first and second inner edges defining a tether slot therebetween, wherein the tether slot is configured to guide passage of a tether coupled to a payload retriever suspended from a UAV when the payload retriever is passing within the channel, a first tether engager that extends in a first direction from the first end of the channel adapted to guide the tether towards the channel, a payload holder positioned near the second end of the channel that is adapted to secure a payload, wherein the channel includes a first projection that extends from the first edge into the tether slot so as to hinder removal of the tether from exiting the tether slot once the tether has entered the tether slot.

Described herein are methods and systems for picking up, transporting, and lowering a payload coupled to a tether of a winch system arranged on an unmanned aerial vehicle (UAV). For example, the winch system may include a motor for winding and unwinding the tether from a spool, and the UAV's control system may operate the motor to lower the tether toward the ground so a payload may be attached to the tether. The control system may monitor an electric current supplied to the motor to determine whether the payload has been attached to the tether. In another example, when lowering a payload, the control system may monitor the motor current to determine that the payload has reached the ground and responsively operate the motor to detach the payload from the tether. The control system may then monitor the motor current to determine whether the payload has detached from the tether.

In some embodiments, systems and methods are provided to enable package delivery and interaction with customers. Some embodiments comprise unmanned aircraft system (UAS), comprising: a crane system comprising a first spool system and a crane motor, the first spool system comprises a first cord that is extended and retracted; a retractable interface system cooperated with the first cord; a package holder configured to hold a first package to be delivered by the UAS at a delivery location; a control circuit coupled with the crane motor to control the crane motor, and to activate the crane motor to extend the first cord and lower the retractable interface system while the UAS is maintained in flight at least at a threshold height; wherein the retractable interface system comprises an input interface to receive input from a customer at the delivery location.

Systems, apparatuses, and methods are provided herein for providing package release for an unmanned aerial system. An apparatus for releasing packages for retrieval by an unmanned aerial system comprises a plurality of arms configured to surround a plurality of packages stacked vertically in an extended position, a plurality of powered hinges at a base of each of the plurality of arms, and a control circuit coupled to the plurality of powered hinges. The control circuit being configured to: determine a height for a first lowered position for the plurality of arms at which the plurality of arms do not obstruct an unmanned aerial vehicle from coupling with a coupling structure on a first package of the plurality of packages positioned at a top of the plurality of packages, and cause the plurality of powered hinges to pivot the plurality of arms from the extended position to the first lowered position.

Described herein are apparatuses that provided various features related to unmanned aerial vehicles (UAVs). An example apparatus may include, among other features, (i) a launch system for a UAV, (ii) a landing feature that is arranged on the apparatus so as to receive the UAV when the UAV returns from a flight, and (iii) a mechanical battery-replacement system that is configured to (a) remove a first battery from the UAV, and (b) after removal of the first battery, install a second battery in the UAV.
