Technologies are changing radically; different organizations and institutions are using various core, allied technologies to make the things, systems, services, and product easier. The development of computing and information technology is changing massively; and as far as agriculture sector is concerned it is also increased in recent past. There are various technologies and systems in respect of agricultural promotion and development. Information technology is dedicated in information related activities in agriculture and allied activities. There are many reasons for the uses of IT and Computing in the Agriculture, namely, huge amount of crops, plants and agricultural product requirement, speed, disease detection, sustainable development promotion, and quality enhancement of agricultural products. Artificial intelligence (AI) powered solutions helps agricultural systems to do more in all sorts with less and further it helps in developing the quality of agro products and ensures faster go-to-market for crops. The complete agriculture landscape been changed by AI and there are many potentialities in regard to the applications of AI and allied technologies, namely, drone-based image processing and precision farming landscape. Different organizations, institutions associated with the agriculture are doing efforts on technological integration and especially AI due to its wider benefits. This paper is theoretical one and talks about the basics of AI and Robotics, Agricultural Informatics and specially applications of AI and Robotics in Agriculture and similar activities.
