Agriculture is one of the oldest forms of
occupation. The use of tools and livestock in the
agricultural process has reduced the human effort.
Major factors that affect agriculture include less holding
area, shortage of seeds, fertilizers, labour and
uncertainty of monsoon. The mechanization of
agriculture refers to the use of tools or machines in the
agricultural process that potentially reduces the human
effort. Although it reduces the human effort in the
agricultural process, it requires complete human
interaction. The automation and robotics application in
the branch of agriculture is at the booming stage when
compared to its wide range of application in other
sectors. Many researches have been done in this field to
automate the process. In the present paper an effort is
made for the design and development of the robot that
can perform various farming operations like ploughing,
field levelling, seeding, watering and pesticide spraying.
The robot is basically a four wheel robotic car. The main
component here is the Arduino which controls all the
process. The bot is controlled with the help of RF
remote. This RF remote has mutiple buttons for
controlling various farming operations. The bot can
navigate the farm in two modes manual mode in which
the direction to the bot is given by user and automatic
mode in which bot autmatically navigate through the
farm without the need of directions from user. This
automatic navigation is possible with the help GPS
receiver and magnometer. While navigating through the
farm the bot can do any of the farming operation
depending upon which opertaion is turned ON by user.
Seeding and watering operations happens in a specific
inetrval depending upon the consecutive distance
between two crops and this interval can be easily change
by manipulating arduino code. Also the design is such
that seeding and watering is done parallelly in 3 tracks
which reduce the farming time drastically. Pesticide
sparying opertion is done continuously. Grooves
mounted at the back of agribot helps in ploughing the
field as bot moves forward. Wodden slab mounted at the
back act as a field leveller so as to close the dug tracks.
The robot developed overcomes the drawbacks in the
traditional method of seeding and watering which
includes wastage of seeds and water, high labour wage,
lower utilization of land etc. By the application of
automation and robotics in the field of agriculture it is
possible to increase the overall efficiency of the
agricultural process and can mitigate effects of labour.
