Delivery of parcels by drones is a relatively new niche in the field of mail forwarding: delivery drones can replace ordinary couriers with a human face.
Most of the proposed solutions currently use quadcopters with six or more propellers. The shipping container is placed in a compartment at the bottom of the drone or attached directly to the aircraft itself. The client receives the package by picking it up from the compartment of the drone that has descended to the ground or by disconnecting it from the rope of the trigger mechanism, thanks to which the drone can not land on the ground.
