I saw a demo recently where they had a drone flying high and it zip-lined a package down to the destination directly below it, so the drone never had to get close to the ground. I’m not sure if that’s current strategy but it seems like a cool idea to cut down on noise and proximity issues.
I think this is the popular route they’re going, to avoid drone theft/vandalism, problem is still the liability of dropping things on people’s heads regardless of CV or other sensors.
That’s actually an idea: create a lightweight Ariel tram way just for package delivery. Sort of like the old vacuum tube networks some cities used to have.
