With everything that's going on right now, a lot of people probably wish a drone could deliver them groceries instead of having to battle it out in the real world or wait for a delivery slot to open up. We have discussed this with Alphabet's Wing drone division, many other providers are doing so, 1 of the major player is Amazon themselves. Click "Read More" to know their plan for drone delivery.
The ability to land autonomous drones in someone's backyard without crashing into anything is a pretty difficult for drones than it sounds, especially in crowded cities landscape that blocks reception needed for an accurate flight. One solution Amazon appears to be looking at is placing radar devices at landing sites, which could bounce signals to a drone to let it know where to land or things to avoid.
Amazon was also awarded another patent this week for using image-based codes to direct drones around, which would probably be helpful for the aircraft when they're maneuvering their way out of an Amazon facility and off for their delivery runs. It like some sort of QR code to provide information for the drones.
One of the great things about robots is that you can tell them to do multiple things at once. Amazon's patent suggests that while drones are out delivering you your packages, they can also be scanning the world below them to make better topographical maps. The patent also suggests that other types of aircraft, from personal drones to helicopters, could be doing the same thing while they're up in the sky. This probably won't do much to allay the worries of privacy advocates who aren't fans of the idea of drones constantly surveying the world below them as they pass, though.
