The agricultural sector is vital to the economy. Agricultural automation is a subject that is getting more and more attention and interest around the world. With the growing number of people, the need for both food and work is rising quickly. The farmers' tried-and-true ways of doing things didn't meet these standards, though. So, high-tech, machine-based methods have come into being. Not only did these new ways of doing things meet the need for food, but they also gave jobs to billions of people. AI has changed the way farming is done in a big way. The effects of climate change, population growth, an unstable job market, and food shortages have been lessened by this new idea. The main goal of this study is to take a look at all of the different ways AI can be used in farming, such as putting cameras and other tools on robots and drones to help with irrigation, weeding, and spraying. These innovations cut down on the wasteful use of water, pesticides, and herbicides. They also protect the soil's nutrition, help people work more efficiently, and increase both output and quality. This study is a summary of what many researchers have found about the state of automation in agriculture, especially in terms of how robots and drones can be used to get rid of weeds. In addition to the different soil water sensing systems, there are also two automatic ways to get rid of weeds. This study talks about drones and the many ways they can be used to spray crops and keep an eye on them. It also talks about how they can be used.
