Drone saw

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 a 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;
• and
• 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.
