A multicopter (100) having a plurality of propellers (1) is configured to be electrically operated. The multicopter (100) is provided with electric motors (2), at least one main battery (3), a generator (4), an engine (5), and a battery condition detecting section (71). The electric motors (2) drive the propellers (1). The main battery (3) is a first electric power source that supplies the electric power to the electric motors (2). The generator (4) is a second electric power source that supplies the electric power to the electric motors (2). The engine (5) drives the generator (4). The battery condition detecting section (71) detects abnormality of the main battery (3). When the battery condition detecting section (71) detects the abnormality of the main battery (3), the generator (4) supplies the electric power that has been converted from motive power from the engine (5) directly to the electric motors (2).

Systems and methods include UAVs that serve to assist carrier personnel by reducing the physical demands of the transportation and delivery process. A UAV generally includes a UAV chassis including an upper portion, a plurality of propulsion members configured to provide lift to the UAV chassis, and a parcel carrier configured for being selectively coupled to and removed from the UAV chassis. UAV support mechanisms are utilized to load and unload parcel carriers to the UAV chassis, and the UAV lands on and takes off from the UAV support mechanism to deliver parcels to a serviceable point. The UAV includes computing entities that interface with different systems and computing entities to send and receive various types of information.

A pan-tilt and an aerial camera containing a pan-tilt. This pan-tilt includes a motor which has a first part and a second part of relative movement, a slip ring which is installed in the motor and has a fixing part and a rotating part, and a control part which is installed under the motor and at which the second part is installed. The center of the motor has a first hole which longitudinally penetrates through, in which the slip ring is installed. The fixing part is static relative to the first part. The control part is electrically connected to the rotating part via a wire which is set to pass through the first hole. The control part is electrically connected with the motor. The pan-tilt can be rotated by 360 degrees.

A transportation network is provided that utilizes autonomous vehicles (e.g., unmanned aerial vehicles) for identifying, acquiring, and transporting items between network locations without requiring human interaction. A travel path for an item through the transportation network may include a passing of the item from one autonomous vehicle to another or otherwise utilizing different autonomous vehicles for transporting the item along different path segments (e.g., between different network locations). Different possible travel paths through the transportation network may be evaluated, and a travel path for an item may be selected based on transportation factors such as travel time, cost, safety, etc., which may include consideration of information regarding current conditions (e.g., related to network congestion, inclement weather, etc.). Autonomous vehicles of different sizes, carrying capacities, travel ranges, travel speeds, etc. may be utilized for further improving the flexibility and efficiency of the system for transporting items.
