Agriculture plays a very important role in human survival. Now - a - days, the availability of manual power has gradually reduced. In order to reduce the manual work power in the field of agriculture, the authors have proposed a model of multi-purpose agricultural robot to perform dropping seeds, monitoring crops, de-weeding, irrigation and pesticide supply. To provide a proper monitoring, the authors have used a technique of the line following robots. This will involve efficient utilization of water resources, intensive plant and soilmonitoring, condition based use of fertilizers and the ability towork in unstructured environments.
