In one embodiment, a controller instructs an unmanned aerial vehicle (UAV) docked to a landing perch to perform a pre-flight test operation of a pre-flight test routine. The controller receives sensor data associated with the pre-flight test operation from one or more force sensors of the landing perch, in response to the UAV performing the pre-flight test operation. The controller determines whether the sensor data associated with the pre-flight test operation is within an acceptable range. The controller causes the UAV to launch from the landing perch based in part on a determination that UAV has passed the pre-flight test routine.

1. A landing perch for an unmanned aerial vehicle (UAV), comprising: a base having a plurality of posts that extend from the base and are configured to couple with apertures of the UAV to retain the UAV in a docked position on the base after landing, wherein one or more of the posts comprise an electrical contact configured to provide an electrical charge to the UAV when the UAV is docked on the landing perch;one or more electromagnets located on one or more of the plurality of posts; anda controller that includes: one or more network interfaces to communicate with a computer network;a processor coupled to the one or more network interfaces and configured to execute a process; anda memory configured to store the process executable by the processor, the process when executed operable to: detect the UAV within proximity of the landing perch;cause the UAV to align the apertures of the UAV with one or more of the plurality of posts of the base; andactivate the one or more electromagnets on the posts to retain the UAV on the landing perch. 2. The landing perch of claim 1, wherein the process when executed is further operable to: determine that the UAV is within a predefined distance, attitude, or orientation relative to the landing perch during approach to the base. 3. The landing perch of claim 1, wherein the process when executed is further operable to: determine that the UAV is within an arrival time at the landing perch during approach to the base. 4. The landing perch of claim 1, wherein the landing perch further comprises one or more proximity sensors, and wherein the process when executed is further operable to: detect the presence of the UAV near the landing perch by the one or more of the proximity sensors. 5. The landing perch of claim 4, wherein the sensor is a lens or a security camera. 6. The landing perch of claim 1, wherein one or more of the plurality of posts comprises a force sensor configured to measure a force exerted on the one or more posts when the UAV is docked onto the perch. 7. The landing perch of claim 1, wherein the process when executed is further operable to: cause the one or more electromagnets to interact with one or more magnets of the UAV. 8. The landing perch of claim 1, wherein the process when executed is further operable to: activate the one or more electromagnets to repel the UAV away from the perch. 9. The landing perch of claim 1, wherein the base further comprises an aperture through which the UAV deposits or receives a package for delivery. 10. The landing perch of claim 1, wherein one or more of the posts comprise an aperture through which a cooling or heating medium is provided to the UAV when the UAV is docked on the landing perch. 11. The landing perch of claim 1, further comprising: an optical or radio transceiver via which the controller communicates with the UAV. 12. The landing perch of claim 1, wherein in the process when executed is operable to: instruct the UAV docked on the landing perch to perform a pre-flight test operation of a pre-flight test routine prior to being launched from the landing perch;receive sensor data associated with the pre-flight test operation from the one or more force sensors of the landing perch, in response to the UAV performing the pre-flight test operation;determine whether the sensor data associated with the pre-flight test operation is within an acceptable range; andcause the UAV to launch from the landing perch based in part on a determination that UAV has passed the pre-flight test routine. 13. A method comprising detecting, by a controller, that an unmanned aerial vehicle (UAV) is within proximity of a landing perch, the landing perch comprising: a base having a plurality of posts that extend from the base and are configured to couple with apertures of the UAV to retain the UAV in a docked position on the base after landing, wherein one or more of the posts comprise an electrical contact configured to provide an electrical charge to the UAV when the UAV is docked on the landing perch, andone or more electromagnets located on one or more of the plurality of posts;causing, by the controller, the UAV to align the apertures of the UAV with one or more of the plurality of posts of the base; andactivating, by the controller, the one or more electromagnets on the posts to retain the UAV on the landing perch. 14. The method of claim 13, further comprising: instructing, by the controller, the UAV docked on the landing perch to perform a pre-flight test operation of a pre-flight test routine prior to being launched from the landing perch;receiving, at the controller, sensor data associated with the pre-flight test operation from the one or more force sensors of the landing perch, in response to the UAV performing the pre-flight test operation;receiving, at the controller, data indicative of an acceptable range for the sensor data associated with the pre-flight test operation;determining, by the controller, whether the sensor data associated with the pre-flight test operation is within the acceptable range; andcausing, by the controller, the UAV to launch from the landing perch based in part on a determination that UAV has passed the pre-flight test routine. 15. A system comprising: a roost having a communication system configured to execute processes to manage communication to the UAVs and a plurality of landing perches for a plurality of unmanned aerial vehicles (UAVs), each landing perch including: a base having a plurality of posts that extend from the base and are configured to couple with apertures of a particular UAV to retain the particular UAV in a docked position on the base after landing, and one or more electromagnets located on one or more of the plurality of posts; anda controller that includes: one or more network interfaces to communicate with a computer network;a processor coupled to the one or more network interfaces and configured to execute a process; anda memory configured to store the process executable by the processor, the process when executed operable to: detect that a UAV is in proximity of the particular perch;align the UAV with one or more of the plurality of posts of a selected perch; andactivate the one or more electromagnets on the posts of the selected perch to retain the UAV on the landing perch. 16. The system of claim 15, wherein the roost is positioned on a road vehicle or a seagoing vessel. 17. The system of claim 15, wherein the roost is positioned on a stationary structure. 18. The system of claim 15, wherein the roost further comprises a loading mechanism to load a parcel onto the selected UAV when in a docked position on the selected perch.
