Abstract: A method for flight path planning of unmanned aerial vehicles using flying routes of birds includes: recording multiple pieces of flight data, wherein multiple recording devices are used to record the multiple pieces of flight data when the birds fly from a first designated point to a second designated point and are respectively installed on the birds; generating an optimal flight path, wherein an analyzing device collects the multiple pieces of flight data and calculates the optimal flight path; and controlling a UAV to fly according to the optimal flight path, wherein the optimal flight path is inputted to the UAV. By virtue of bird's nature automatically avoiding obstruction and adapting to wind direction and air flow, multiple obstruction-free recording points between two places can be acquired to form an optimal flight path with the shortest flying time or distance.

Abstract: An exemplary packing case (20) includes a main body (21) and a plurality of protrusions (213). The main body includes four side walls configured for receiving substrates. The protrusions are formed at inner sides of two opposite side walls of the main body, respectively. The protrusions are separately parallel to each other. Each of the protrusions has a wedge shape and is perpendicular to the two opposite side walls. Each two adjacent protrusions define a groove (215) therebetween. The groove includes a first portion and a second portion. The first portion is adjacent to the corresponding side wall. A width of the second portion increases along with increasing of a distance far away from the corresponding side wall.

Abstract: An exemplary packing apparatus includes a main body (201), a cover (202), and a partition layer (212). The cover is configured to be attached to the main body and cooperatively forms a receiving space with the main body. The partition layer is received within the receiving space.
