1. A system of unmanned aviation vehicles comprising the plurality of unmanned aviation vehicles capable of vertical landing and takeoff, the system communicating through a proprietary network or through GPS, WIFI and/or commercially available networks, and further comprising:
at least a drone box (100) having
a drone platform (110) with a plurality of limiting boundaries (113), made of a source transmitter (120) and a source receiver (121) with magnetic or optical line of sight radiation therebetween, and disposed along the limiting boundaries (113),
the drone platform (110) divided into a number of sensor zones (111), that are mechanically contiguous and electrically separated by an insulated separator (114) of insulation width (115), each sensor zone (111) having identification coordinates,
a levelled upper surface (117) of the drone platform (110),
a plurality of platform covers (112), and
at least two mounting dispositions (130) provided at a lower end of the drone box (100), each mounting disposition (130) manually adjustable in a longitudinal direction (131), and has a flexible cushion (135) at a free end (132) of the mounting disposition (130) capable of adjusting to an orientation commensurate with a surface of disposition (150),
each unmanned aerial vehicle being a drone (10) having a plurality of ground interfaces (11), each ground interface (11) of each drone (10) having a unique address code, each ground interface (11) has a charging terminal (13) at a far end, each charging terminal (13) having an interlocked switchable electricity polarity positive (+ve) or negative (−ve) or neutral (N),
a minimum terminal dimension (15) of the charging terminal (13) is such that a minimum contact area (14) is ensured when an axis (16) of the ground interface (11) of the drone (10) exactly coincides with a center of intersection (116) of the adjacent sensor zones (111), the ground interface (11) facilitates charging of batteries installed in the drone (10) via the sensor zones (111) after a safe landing of the drone (10).
