  The agriculture sector requires a lot of labor and resources. Hence, farmers
are constantly being pressed for technology and automation to be
cost-effective. In this context, autonomous robots can play a very important
role in carrying out agricultural tasks such as spraying, sowing, inspection,
and even harvesting. This paper presents one such autonomous robot that is able
to identify plants and spray agro-chemicals precisely. The robot uses machine
vision technologies to find plants and RTK-GPS technology to navigate the robot
along a predetermined path. The experiments were conducted in a field of potted
plants in which successful results have been obtained.
