Payload delivery and drop device for unmanned aerial vehicle for automatic release upon surface contact

摘要

Embodiments of a payload delivery and drop device for an unmanned aerial vehicle, and method of its use are described herein. In some embodiments, an apparatus includes a moveable collar defining a lumen having a centerline, and a rigid bar that has a first portion and a second portion different from the first portion. The first portion of the rigid bar has a centerline and the second portion of the rigid bar has a centerline different from the centerline of the first portion. The second portion of the rigid bar is disposed within the lumen of the collar when the rigid bar is in a first position. The centerline of the first portion of the rigid bar is substantially non-parallel to the centerline of the lumen of the moveable collar when the rigid bar is in the first position. The centerline of the second portion of the rigid bar is substantially non-parallel to the centerline of the lumen when the rigid bar is in the second position.
