Option:Helicopter

Pros

Diverse

As helicopters are not affected by the quality and/or presence of roads they can be used in both urban and rural areas, making them very diverse and suited for all kind of environments.

Delivery at door

Helicopter drones are typically relatively small and can take-off and land vertically in a small space. This means that they can land (almost) everywhere making delivery at your door possible. The helicopters have no fixed delivery start and end point locations.

Shortest routes

Because helicopters can fly they are not restricted to the infrastructure. This means that they can take the shortest routes to your home reducing travelling time and costs.

Small chance of being damaged

As helicopters fly high above everything and everyone there is little chance of getting damaged. Helicopters are thus a safe way to make sure your package gets to its destination undamaged.

Fast

As mentioned before the helicopters are high above everything. Because of this they can travel at high speeds without risk of collisions, making delivery times faster.

Cheap After the first big investment of buying the drones the costs are relatively low because they run on electricity.

Cons

Weight of package Because the drone needs to generate enough lift to lift the package the items can’t be very heavy or the drones need to be very large which takes away the advantage of door delivery.

Weatherproofness A helicopter drone will typically be really lightweight. Because of this strong winds could cause the helicopter to swerve or crash. Other weather conditions like for instance rain could also cause the drone to crash as it limits the visibility of the sensors.

Restrictions Nowadays there are a lot of restrictions on where drones are allowed to fly. This could make it hard for these vehicles to deliver packages everywhere. However, this problem could be solved by making new clear rules.

Small range Currently drones have a small range due because flying uses a lot of battery power. This problem could be solved with better batteries.

Privacy issues It is very likely that the helicopter drone will use some sort of camera to look where to land. When the drone flies over cities this camera can capture a lot of people giving rise to privacy issues. Also the use of GPS coordinates to locate where to deliver the packages can cause problems.

Failure can have large consequences Because the drones fly at great heights with packages which can weigh up to a few kilos a failure could be a very dangerous situation. If such drone crashes onto someone this could cause great injury.
