Following from my first article on drones and how they might be used for making deliveries and how they could be organised I wanted to follow up with a closer look at how they would work when they reached their destination. Google and Amazon are both testing drones for this purpose, so it is a case of when, not if they will be used for this purpose, and I wanted to look at the potential impact on buildings for designers. I am interested in this in the first instance because I see that from their widespread use could lead to the removal of a large percentage of delivery vans off the streets of cities, a reduction in delivery cost, energy saving and lower pollution. This will bring attendant benefits to the attractiveness of urban life, with lower noise from traffic and more convenience for sending and receiving deliveries.
The diagram below shows the path a drone will take to its destination by ‘hopping’ from location signals from each address. While in the ‘circle’ of the signal it picks up delivery codes matching its package, these delivery codes will be time stamped, so to find the destination it has to follow the time stamped codes to their point of origin.
Another benefit arising from my ideas about how their distribution system would work is that a recipient of a package could have it delivered to wherever they were, in the office, at home, or in the park. That is covered in more detail in the first article.
I wanted to look at what happens when the drone arrives to your home or building. If you aren’t there, what happens to the delivery? How is it stored, and protected until you arrive to collect it.
I am assuming that there will be a horizontal separation of drone traffic above an urban zone. See Fig 1. Drones would be allowed to circulate freely in this area, with helicopters restricted to fly above them. Landing zones for helicopters would be created by geofenced openings in this layer.
To begin with the drone has to be guided down to its destination. Fig 2 shows a diagram of a geofenced area which a drone could follow when it leaves the circulation zone above buildings.
Once the drone has followed this guidance down to its landing area and has safely landed, it can deliver the parcel. The parcel needs to be stored until it is collected, and this could be a delivery box that could sit in a garden, or on a balcony if one is available, or on your roof if it is flat and accessible. This is shown in Fig 3.
The delivery box has a lid which opens when a drone arrives with a delivery, and the package is dropped by the drone into the box, which then closes up awaiting the owners to collect the package, or for another delivery. The box would be equipped with a system that recognises the delivery code of the package that the drone uses to match owner and package. The same code is used to open the delivery box by the package owner.
For people living in apartment buildings the problem is a bit more complex. If deliveries could be accepted on a balcony, the solution is similar to that for a garden or flat roof. A delivery box with a hatch and a door would work. If this can’t work and deliveries have to be made to the roof, the storage box has to be big enough to anticipate a lot of deliveries and needs an arrival box and a storage box, the sequence of how it could work is shown is Fig4.
This arrangement assumes that a concierge would come and collect the deliveries and take them to their relevant destinations. This is a weak point in the security of the system, and assumes that the concierge is trustworthy. In all cases the delivery is electronically tagged with a unique identifier, enabling the recipient to track its movement from when it leaves the shop to when it arrives at the delivery box.
