摘要： Various embodiments include methods, devices, and robotic vehicles that adjust a proximity threshold implemented in a collision avoidance system based on whether a payload is being carried. Methods may include determining whether a payload is carried by the robotic vehicle, setting a proximity threshold for collision avoidance in response to determining that a payload is carried by the robotic vehicle, and controlling one or more motors of the robotic vehicle using the proximity threshold for collision avoidance. Some embodiments may include raising the proximity threshold when a payload is not being carried or decreasing proximity threshold when a payload is being carried. Some embodiments may include determining a classification of a payload and setting the proximity threshold based at least in part on the classification.

摘要： A long-distance drone (100) and a method of improving stability, robustness, endurance and/or durability of the drone (100) and a method of controlling a roll motion of the drone (100) are provided. The drone (100) includes a main body (110), two main wings (113, 114) and two forewings(111, 112), a left linear support (120) spaced apart from said main body (110) connecting the left forewing (111) to the left main wing (113), a right linear support (121) spaced apart from said main body (110) connecting the right forewing (112) to the right main wing (114), at least two propellers (131,132,133) coupled to the left linear support (120), at least two propellers (134,135,136) coupled to the right linear support (121). Therefore, the drone (100) is sufficiently efficient to travel longer distances, and when one propeller (131,132,133,134,135,136) fails, the drone (100) may still function and continue to stay in the air.

摘要： An imaging device can be mounted on a vehicle and used to capture images. The imaging device can include a camera assembly rotatable relative to a platform of the vehicle and about two or three camera axes. The camera assembly can include a camera and a mirror attached to the camera. The mirror can be rotatable relative to the camera and about one or two mirror axes, different from the camera axes. Users can provide input to controllers that operate the vehicle, the camera, and the mirror to control both flight and the line-of-sight of the camera. The controllers combine separate inputs as well as measured conditions, such as inertial angles, to coordinate control of vehicle, camera, and mirror parameters, such as yaw adjustments to both the camera and the mirror to achieve a desired line-of-sight.

摘要： Disclosed herein is a modular aerial vehicle system having a fuselage module configured to couple with a plurality of lift generation modules. The modular aerial vehicle system may comprise a fuselage module and a lift generation module. The fuselage module can include a first attachment interface, an avionics system operatively coupled with a power unit (e.g., via an ESC), and a communications system operatively coupled with the flight controller. The lift generation module can include a second attachment interface and a plurality of propulsors. The fuselage module may be configured to removably couple with the lift generation module via the first and second attachment interfaces. The first and second attachment interfaces may comprise (1) a plurality of electrical contacts to facilitate electrical communication between the fuselage module and the lift generation module and/or (2) one or more retention devices to couple structurally the lift generation module with said fuselage module.

摘要： A propeller assembly (200) comprising a propeller hub (201) which can be driven about an axis and at least two propeller blades (203) each mounted to the hub at a point distal from the axis by pivoting means (203, 211, 212) alloying the propeller blades to pivot generally parallel to the said axis between at least two positions relative to the hub, a first, folded position in which the propeller blade is not aligned with the axis and the point and a second, deployed position in which the propeller blade is aligned with the axis and the point, in which the pivoting means (203, 211, 212) is configured to allow the propeller blades to pivot freely relative to the hub when in the first position and, on driving the hub about the axis, to allow the propeller blades to pivot relative to the hub until the or each propeller blade is aligned with the axis and the point, the pivoting means being adapted to hold the or each propeller blade in the second position for as long as the bub is driven. An air vehicle (700) comprising at least one such propeller assembly (701) is also described..

摘要： An apparatus for mounting cameras to a drone may include a frame having camera mounts for mounting two 190-degree field-of-view cameras in a back-to-back orientation. Positioning two 190-degree field-of-view cameras in a back-to-back orientation enables obtaining 360-degree field-of-view by stitching images from the two cameras together. The frame may be configured to position the cameras at a 30-40-degree tilt angle (e.g., 35°) with respect to a main axis of the drone to enable the respective images to be stitched together with reduced stitch lines while allowing the lower-facing camera to be used for viewing the ground. In some embodiments, the camera apparatus may be mounted to a drone dampening system.
