ABSTRACT
Robots, in general, have fascinated human beings since ancient period. Robots were initially construed as thinking machines and those capable of certain activity helpful to mankind. Robotic clocks based on movement of water were among earliest automatic machines. Agricultural expanses that generate grains/forage in large scale are worldwide in distribution. So far, large-scale production has been accomplished using mechanization, and cheap human labor leading to perceptible economic gains to farmers. Effort to replace human labor in the crop belts with robots has been delayed. By definition, Agricultural robot or Agri-robot could be autonomous or semi-autonomous equipment used for various procedures during agricultural crop production. Agri-robots are used mainly in land preparation, ridging, making channels, spraying liquid fertilizers, spraying pesticides, sprinkling irrigation water and most importantly in harvesting grains or picking fruits. The new generation agricultural robotics envisages use of small, compact and lightweight farm vehicles capable of tillage, inter-culture and other operations related to soil management.
