The invention discloses a multi-rotor unmanned aerial vehicle based on a universal rotor set. The multi-rotor unmanned aerial vehicle based on the universal rotor set comprises a rack, a flight control system, a GPS (Global Positioning System), a controller and the universal rotor set, wherein the rack comprises a center plate and a plurality of balance rotor sets uniformly extending from the periphery of the center plate; a plurality of lead frames are uniformly arranged on the periphery below the lower part of the center plate; the universal rotor set is arranged vertically below the center plate; the flight control system and the GPS are arranged above the center plate; and the flight control system is used for controlling the universal rotor set to be adjusted in different directions and speeds. The multi-rotor unmanned aerial vehicle based on the universal rotor set has the beneficial effects that the practicability is high, the flight speed and direction of the unmanned aerial vehicle are controlled through the universal rotor set; the balance of the unmanned aerial vehicle is kept through the multiple groups of balance rotors; the power consumption rate is reduced; the cruising power and flexibility are promoted; the practicability and convenience of the unmanned aerial vehicle are improved; and the multi-rotor unmanned aerial vehicle based on the universal rotor set has practical significance and can be produced in quantity to achieve the purpose of popularization.
