The landing gear could also have a “barbed spike” that could screw into the surface for extra stability. Or it could also have a magnet to land on metal surfaces or a “vacuum suction cup”.
Amazon outlined that the drone could be made from lightweight materials such as graphite, aluminum or carbon fiber. The top part of the drone would have the ability to rotate which would allow the flying machine to position itself in the correct place in account for environmental conditions like wind.
“Specifically, the UAV may be re-oriented while it is landed by rotating the support coupling so that the body of the UAV rotates while the landing gear assembly remains stationary,” Amazon’s patent said.
In the second patent, the U.S. e-commerce titan laid out its ideas for robotic propellers that could help the drone face less resistance in the air. The patent outlines adjustable winglets on the propeller, much like those found on airplanes, which will help the drone counter the drag created by pressure in the air as it flies.
They will be adjustable and react to environment conditions.
