This paper shows the plan and manufacture of farming automaton. Drones were primarily used in the military. As drones become an integral part of smart (or ‘precision’) farming, they assist farmers with managing a wide scope of difficulties and receive an incredible number of rewards. Precision technology has driven the cultivating upheaval as of late. Monitoring crops from the sky utilizing agricultural drones looks set to drive the following, as agronomists, agricultural engineers and farmers turn to UAVs (or UAS) to acquire productive harvest bits of knowledge and to all the more precisely design and deal with their tasks. The agricultural drone is manually controllable by remote controller. The motivation behind our venture is to build up a quad-copter which conveys pesticides to splash everywhere throughout the ranch which decreases crafted by ranchers just as it completes his work soon. The automaton mounted sprayer essentially comprise of BLDC engines, electronic speed controller, Lipo(Lithium Polymer)batteries, pesticides tank, sprinklers, visual eye camera and supporting edge alongside landing gear. This helps the farmers to be proactive against their crops, having a knowledge about the water damage, compaction and disease detection to prevent the crops from further damage. This sprayer is very useful where human mediations are unreasonable for showering of synthetic substances on crops including rice fields and ranch crops similarly as harvests under scene lands.
