INTRODUCTION
• India is the second-largest agricultural production country in the
world
• In India nearly 60% of the population depends upon agriculture
• Nowadays agricultural plants are damaged or killed by insect
pests. It results in reduced yields, lowered quality in products
• The farmers are using pesticides in agricultural production to
control pests and insects
• the labor cost high and in the pesticide spraying operation farmers
are direct contact with spraying which leads to skin cancer,
asthma,
• To overcome this problem the automatic pesticide-sparing robot
will be developed

LITERATURE REVIEW
• A M Kasim [1] (2020): Presented on “Design and Development
of Autonomous Pesticide Sprayer Robot for Fertigation Farm”
The Autonomous robot used in agriculture for the purpose of
pesticide spraying with the ability to navigate in the farm,
recognize the target and regulate the spraying mechanism.
• Ashutosh B [2] (2018): Presented on “Agricultural pesticide
spraying robotic system controlled using android application”
Using components such as ESP32 Microcontroller for the control
of agriculture robot, geared motors that facilitate the robot wheels
to move and mobile application to guide the robotic movement are
incorporated in this agriculture robotic vehicle.

ROBOT DIMENSIONS
SL no Item Specification
1 Tank dimensions 240×240×210 (l×b×h) in mm
2 Area of the tank 57600mm2
3 Volume of the tank 12×10⁶
4 Tank storage capacity 5 Ltr
5 Pay load 15 kg
Drive Wheel Motor Torque Calculation:
oRolling Resistance : RR= 1.66N
oGradient Resistance: 7.5N
oAcceleration Force: 3.05N
oTotal Tractive Effort 12.21N
oWheel Motor Torque: 0.6105N
Torque on each driving motor = total torque/no. of motor used = 1.54kgcm .
So we are using motors with torque of 2kgcm in order to avoid any problem

Results and Discussion:
Fig: Pesticide Spraying Robot
• Specialized Android pesticide Sprayer robot is successfully spray the pesticide to
each plant without human intervention.
• The robot will easily navigated and controlled and the robot will easily navigated
and controlled up to 100 meters distance by Bluetooth module.
• Even illiterate also able to operate this android pesticide robot. The robot is
successfully travelled constantly in flat surface areas. As compared to manual
pesticide spray system the robot requires less time to achieve particular task.

Conclusion
• In this project we come up with low cost pesticide spraying robot.
The project carried out by made an impressing task in agricultural
fields and farms.
• The project has been developed to reduce the wastage of pesticide
also to inspire and encouraging the physically challenged people
to get into agriculture.
• Through this farmers workload and health issues are reduced.
