Only one item can be delivered at a time. It can’t weigh more than 5 pounds. It can’t be too big. It can’t be something breakable, since the drone drops it from 12 feet. The drones can’t fly when it is too hot or too windy or too rainy.
You need to be home to put out the landing target and to make sure that a porch pirate doesn’t make off with your item or that it doesn’t roll into the street (which happened once to Lord and Silverman). But your car can’t be in the driveway. Letting the drone land in the backyard would avoid some of these problems, but not if there are trees.
Amazon has also warned customers that drone delivery is unavailable during periods of high demand for drone delivery.
The problem is that the bigger and heavier the craft the higher it’s minimum drop height is going to be because it’s more dangerous and needs more clearance.
Obviously it also becomes much more costly to run.
Put a little parachute on the package to soften the fall! /s
That made me laugh… I was imagining a small parachute hooked up to a plasma TV 😲
