The core of drone delivery: safety, safety and safety.
The appearance of Wing’s UAV is distinctive. It looks like a hybrid of a glider and a helicopter with not only 6 hovering rotors on the left and right sides of the fuselage, but also wings and 2 cruise rotors. The aircraft can lift and hover vertically, and cruise smoothly in lateral flight.
In order to minimize the harm to people caused by the accidental fall, the fuselage of Wing is wrapped with foam and thus it is very light.
Wing said that the design of the entire aircraft was completed by the cooperation of institutions including Virginia Tech, and that the safety of the aircraft was tested specifically in designing.
During the delivery, Wing generally controls the flight in a low-altitude area 30-40 meters above the ground, and complies with urban airspace management, basically not affecting manned aircraft.
One of the biggest difficulties for drone delivery is to ensure the safety of landing. Generally speaking, drones need to use sensors to find an open and safe place in order to land smoothly. However, the ground condition is complicated, and it is an engineering problem to land safely.

The design that Apple has insisted on for more than 10 years is going to disappear? - part 2
First introduce the reasons why Apple is unwilling to abandon the Lightning interface, and from this draw forth the MFi certificate. Then introduce the purpose of Apple's MFI certificate and the author's interpretation of this purpose. Finally, introduce that the current fast charging technology is developing very rapidly, and Apple has fallen behind in this regard.
Mechanical hard drives will be eliminated? (III)
It is crucial for scientists to find ways to manage the thickness of COC in order for them to increase the mechanical hard drive’s storage capacity per square inch.
Only 37 square meters? What black technology is hidden in the "container apartment" where Musk lives? - part 5
First introduce Boxabl's orders and cooperation, then take a province of Canada as an example, calculate the required transport and assembly costs, and calculate the total cost of prefabricated houses. Next, introduce the breakdown categories of assembly costs, and finally point out that the prefabricated houses are quite cost-effective compared with other houses.
