Abstract

A base station for automated battery pack or payload exchange and methods for using the same. The base station provides a landing surface for receiving a mobile platform and includes a manipulator controlled by a manipulator compartment for accessing resource storage. The base station is operable to ascertain a location of the platform on the landing surface and move the manipulator to the mobile platform. Thereby, the base station system advantageously accommodates low-accuracy landing of the mobile platform and further enables extended and autonomous operation of the mobile platform without the need for user intervention for exchanging battery packs and payloads.

First claim

1 .- 30 . (canceled)

31 . A base station for a mobile platform having a payload, comprising:
a landing surface; and a maintenance system configured to:
ascertain a location of the mobile platform on the landing surface,
move to the mobile platform based on the ascertained location of the mobile platform, and
actuate a power switch of the mobile platform.

32 . The base station of claim 31 , wherein the maintenance system is configured to move translationally along an X-axis, a Y-axis, or a Z-axis or rotationally to the mobile platform based on the ascertained location of the mobile platform.

33 . The base station of claim 31 , wherein the maintenance system is further configured to interact with a selected replacement payload and the payload of the mobile platform automatically and without user interaction.

34 . The base station of claim 31 , wherein the maintenance system is further configured to ascertain a distance between the mobile platform and another base station located on a flight path of the mobile platform.

35 . The base station of claim 34 , wherein the maintenance system is further configured to provide a signal to the mobile platform, the signal instructing the mobile platform to land on the landing surface or travel to the other base station.

36 . The base station of claim 31 , wherein the maintenance system is further configured to connect a physical cable assembly to the mobile platform.

37 . The base station of claim 36 , wherein the physical cable assembly comprises at least one of a first communication cable assembly for transmitting data from the base station to the mobile platform, a second communication cable assembly for transmitting data from the mobile platform to the base station, a power cable for providing electrical power to the mobile platform, or a fuel line for refueling the mobile platform.

38 . The base station of claim 31 , wherein the maintenance system is further configured to wirelessly provide power to the mobile platform.

39 . The base station of claim 38 , wherein the landing surface comprises a charging pad for wirelessly providing the power to the mobile platform.

40 . The base station of claim 38 , wherein the landing surface comprises an electric coil system for wirelessly providing the power to the mobile platform.

41 . The base station of claim 31 , wherein the maintenance system is further configured to move the mobile platform from the ascertained location to a predetermined location on the landing surface.

42 . The base station of claim 41 , wherein the predetermined location comprises one or more receiving cavities defined on a predetermined surface of the landing surface and configured to receive one or more landing legs of the mobile platform.

43 . The base station of claim 31 , wherein the maintenance system comprises a mechanical manipulator configured to:
move along an X-axis and a Y-axis to a selected replacement payload positioned in a selected resource-slot, extend a resource-carriage along a Z-axis, grasp the selected replacement payload; retract the resource-carriage along the Z-axis to remove the replacement payload from the resource-slot, move the replacement payload proximate to the ascertained location of the mobile platform, insert the replacement payload into a mobile platform resource-slot provided on the mobile platform, and decouple from the replacement payload.

44 . The base station of claim 31 , wherein the maintenance system is further configured to:
identify a service marker on the mobile platform indicative of a position of the payload, and interact with the payload based on a location of the service marker.

45 . A method of inserting a replacement payload into a mobile platform, comprising:
ascertaining a location of the mobile platform on a landing surface; grasping the replacement payload positioned in a selected resource-slot; moving the replacement payload to the mobile platform based on the ascertained location of the mobile platform; inserting the replacement payload into a payload-slot positioned on the mobile platform; and decoupling from the replacement payload.

46 . The method of claim 45 , wherein moving the replacement payload comprises moving a maintenance system grasping the replacement payload translationally along an X-axis, a Y-axis, or a Z-axis or rotationally of the landing surface to the mobile platform based on the ascertained location of the mobile platform.

47 . The method of claim 45 , wherein grasping the replacement payload comprises moving a mechanical manipulator of a maintenance system along an X-axis, a Y-axis, or a Z-axis of the landing surface.

48 . A maintenance system comprising:
a sensor for ascertaining a location of a mobile platform on a landing surface; and a mechanical manipulator configured to:
grasp a replacement payload positioned in a selected resource-slot,
move the replacement payload to the mobile platform based on the ascertained location of the mobile platform,
insert the replacement payload into a payload-slot positioned on the mobile platform, and
decouple from the replacement payload.

49 . The maintenance system of claim 48 , wherein the mechanical manipulator is further configured to move translationally along an X-axis, a Y-axis, or a Z-axis or rotationally of the landing surface to move the replacement payload to the mobile platform based on the ascertained location of the mobile platform.

50 . The maintenance system of claim 48 , wherein the mechanical manipulator is further configured to move along an X-axis, a Y-axis, or a Z-axis of the landing surface to grasp the replacement payload.
