To design a drone mounted with spraying mechanism having 12 V pump, 6 Litre storage capacity tank,4 nozzles to atomize in fine spray, an octocopter configuration frame, suitable landing frame, 6 Brushless Direct Current (BLDC) motors with suitable propellers to produce required thrust (at 100% RPM) and suitable Lithium- Polymer (LI-PO) battery of current capacity 16000 mAh and 22.2 V to meet necessary current and voltage requirements.

A First-Person View (FPV) camera and transmitter can also be fixed in the drone for monitoring the spraying process and also for checking pest attacks on plants. This pesticide spraying drone reduces the time, number of labour and cost of pesticide application. This type of drone can also be used to spray disinfectant liquids over buildings, water bodies and in highly populated areas by changing the flow discharge of the pump.
