A term used to describe technology that increases farm productivity and automates the cycle of crop or livestock production, is frequently linked to farm automation. Automation is the work done by robot without any man power. Automation used in all fields e. g., automobiles, manufacturing fields etc. Automation supports agriculture in the evaluation and maintenance of crops by using large-scale robotics and micro robots. Robotic farm swarms are one example of agricultural technology that is automated. This involves using numerous agricultural robots each equipped with multiple microscopic sensors that predict, extract, monitor, and cultivate crops without human intervention. Automation also includes precision agriculture Automation agriculture continuously developed by last few decades but automation agriculture by using modern technology (IoT, AI) is further more useful in different ways. The emerging agriculture technologies included blockchain, drones, satellites etc.
