1. An unmanned aerial vehicle (UAV) for trimming tree branches, said UAV comprising:
a base supporting a propulsion system for generating thrust through a plurality of flight impellers secured thereto to enable controlled flight;
a protective frame coupled to said base extending outwardly that provides protective enclosures for said impellers;
a first articulating arm secured to said base having pivoting rotational coupling along a proximal end with the length of said first articulating arm extending to a distal end and a second articulating arm having a proximal end with the length of said second articulating arm extending to a distal end, wherein said first articulating arm is pivotally coupled to said second articulating arm below a lower surface of said base;
a saw mechanism coupled to said distal end of said second articulating arm having a cutting chain that spins around a chain base;
a control system including a set of processors and actuators configured to receive and process input data and control the flight parameters of the UAV;
a power source for providing electrical power to the UAV components, said power source including a battery pack slidably positioned along a slide table coupled to said lower surface of said base and movable between a forward position along said proximal end of said first articulating arm and an aft position along an outer edge of said frame; and
a micro engine coupled to a fuel tank to generate power for recharging said battery power pack and to operate said saw.
