Abstract: The present invention provides a stackable drone and a drone swarm comprising at least two stackable drones. Each drone comprising: a fuselage comprising a first end and a second end; a mating structure arranged in the fuselage and configured to have an opening at the first end of the fuselage, the mating structure forming a mating recess on a first side of the fuselage, the mating recess having an opening at the first side of the fuselage for receiving a mating projection from a further stacking unmanned aerial vehicle. The stackable drones do not require a large area of ground for take-off and landing, require only a small space for storage and transportation. When landing, based on the conical or pyramidal structure, the drone may slide down by gravitational force into the mating recess of another drone thereunder without needs of high precision positioning or alignment system.
Abstract: This invention comprises a control device and a communication port device applied to drone, and a drone using such devices. The control device comprises a carrier board and a main control board that is detachably configured on the carrier board, said main control board is electrically connected with the carrier board, and the carrier board is configured with an interface device in which connections between a plurality of kinds of external devices with said carrier board are established. The carrier board is mainly used for connection with other external electronic devices and power distribution, and the main control board is responsible for processing sensor data and delivering control information. The main control board and the carrier board are connected through a single interface to enable a data transmission. The communication port device is configured on the drone flight controller.
