ABSTRACT
Agricultural Robot or agribot is a robot deployed for agricultural purposes.Fruit
picking robots, driverless tractor / sprayer, and sheep shearing robots are designed to replace
human labour. In most cases, a lot of factors have to be considered (e.g., the size and colour of
the fruit to be picked) before the commencement of a task. Robots can be used for
other horticultural tasks such as pruning, weeding, spraying and monitoring. Robots can also be
used in livestock applications (livestock robotics) such as automatic milking, washing and
castrating. Robots like these have many benefits for the agricultural industry, including a higher
quality of fresh produce, lower production costs, and a smaller need for manual labour. Our
robotic vehicle is an agricultural machine of a considerable power and great soil clearing
capacity. This multipurpose system gives an advanced method to seed sowing, ploughing,
watering the crops and harvesting with minimum man power and labour making it an efficient
vehicle. The machine will cultivate the farm by considering particular rows and specific columns
at fixed distance depending on crop. Moreover the vehicle can be controlled through Bluetooth
medium using an Android smart phone. The whole process calculation, processing, monitoring
are designed with motors and interfaced with Microcontroller.

CHAPTER 1
INTRODUCTION
“The discovery of agriculture was the first big step toward a civilized life. “Is a famous
quote by Arthur Keith. This emphasizes that the agriculture plays a vital role in the
economy of every nation. Since the dawn of history agriculture has been one of the
significant earnings of producing food for human utilization. Today more and more lands
are being developed for the production of a large variety of crops.
The field of agricultureinvolves various operations that require handling of heavy
materials. For example, in manual ploughing, farmers make use of heavy
ploughingmachines. Additionally, while watering the crops farmers still follow the
traditional approach of carrying heavy water pipes. These operations are dull, repetitive,
or require strength and skill for the workers.
In the 1980’s many agricultural robots were started for research and development.
Kawamura and co-workers developed the fruit harvesting robot. Grand and co-workers
developed the apple harvesting robot. They have been followed by many other works.
Over history, agriculture has evolved from a manual occupation to a highly industrialized
business, utilizing a wide variety of tools and machines. Researchers are now looking
towards the realization of autonomous agricultural vehicles. The first stage of
development, automatic vehicle guidance, has been studied for many years, with a
number of innovations explored as early as the 1920s. The concept of fully autonomous
agricultural vehicles is far from new; examples of early driverless tractor prototypes using
leader cable guidance systems date back to the 1950s and 1960s.
The potential benefits of automated agricultural vehicles include increased productivity,
increased application accuracy, and enhanced operational safety. Additionally, the rapid
advancements in electronics, computers, and computing technologies have inspired
renewed interest in the development of vehicle guidance systems. Various guidance
technologies, including mechanical guidance, optical guidance, radio navigation, and
ultrasonic guidance, have been investigated.
A robot is a machine that can be programmed and reprogrammed to do certain tasks and
usually consists of a manipulator such as a claw, hand, or tool attached to a mobile body
or a stationary platform.
Agribot Introduction
Dept of CSE, NCET, Bengaluru 2 2015-2016
Autonomous robots work completely under the control of a computer program. They
often use sensors to gather data about their surroundings in order to navigate.
Tele-controlled robots work under the control of humans and/or computer programs.
Remote-controlled robots are controlled by humans with a controller such as a joystick
or other hand-held device. The word “Robot” came from the Czech word Robota, which
means forced labour or work.
The current state of agricultural robotics:
Today agricultural robots can be classified into several groups: harvesting or picking,
planting, weeding, pest control, or maintenance. Scientists have the goal of creating robot
farms. Where all of the work will be done by machines. The main obstacle to this kind of
robot farm is that farms are a part of nature and nature is not uniform. It is not like the
robots that work in factories building cars. Factories are built around the job at hand,
whereas, farms are not. Robots on farms have to operate in harmony with nature. Robots
in factories don’t have to deal with uneven terrain or changing conditions. Scientists are
working on overcoming these problems.
RobotsUsed for Agriculture:
The number of agricultural robots, agrobots, is increasing each year. The jobs they can do
are also increasing with new technology in hardware and software. Robots are milking
cows, shearing sheep, picking fruit, weeding, spraying, and cultivating, they use GPS and
sensors for navigation. The new robots are getting smaller and smarter.
Fungicides: Robots can be used to combat plant diseases that cause a lot of damage to
crops. Fungi are the most common causes of crop loss in the entire world. To kill a fungal
disease you need a fungicide, a kind of pesticide. Fungal diseases interfere with the
growth and development of a crop. They attack the leaves which are needed for
photosynthesis and decrease the productivity of the crop and cause blemishes on the crops
which make them worth less on the market. After the crops are harvested fungi can grow
and spoil the fruits, vegetables, or seeds. Robots can treat plants that have been infected
or destroy them if necessary. They could treat just the plants that need it, instead of
covering the entire crop with fungicide.
Agribot Introduction
Dept of CSE, NCET, Bengaluru 3 2015-2016
Herbicide: Another use for robots is in weeding. Robots can pull weeds from around
the plants or just cut the tops off. All of the material can be collected by a robot and
brought to a composting site limiting the need for herbicides, chemicalsthat destroy or
inhibit the growth of plants. Herbicides are intended to kill weeds but many times also
damage the crops.
Pesticide: Pesticides are used to control insects that can be harmful to crops. They are
effective but have many side effects for the environment. Insects also adapt to the toxin in
a pesticide and the survivors breed and pass the resistant trait on to the next generation
making stronger insects that are harder to kill. Robots could solve this by removing pests
from the crops without using chemicals. They might suck them up with a vacuum. A
bellow base air system makes a vacuum that doesn’t require the large amount of power of
regular vacuum systems. There are ways to kill the insects without chemicals. Microbial
fuel cells could be used to reduce the insects to electrical power with bacteria. Pesticides
kill everything. Robots could be programmed to rid particular pests and not harm
anything else.
Mushroom Picking Robot:
Mushrooms are a very difficult crop to grow. There is a lot of labour involved. Many
mushroom farms are becoming extremely high tech. They use computerized systems and
monitor all production phases. The robot mushroom picker is an ongoing research project
at the University of Warwick in the UK. Their goal is to develop farm machinery that can
reduce the labour costs of producing farm crops, in this case, mushrooms. The robot picks
the mushrooms using a small suction cap on the end of its robotic arm. The robot has a
charged coupled camera on board to tell which mushrooms to pick in a tray or bed, since
mushrooms mature at different times during a six to ten week period. It uses the camera
to tell the exact size of the mushroom and only pick the correct ones. Mushrooms grow in
dark, damp places that are often inhospitable to humans. This makes the robot a perfect
choice to work on a mushroom farm. The robots can only work half as fast as a human,
but it doesn’t mind working in the dark, or for 24 hours a day.
There are many advantages to robotics as well as removing the high cost of labour. One is
that it will do a job very repetitively and very much the same every time, so you can get
some huge quality improvements in a number of areas. One of the key advantages in
Agribot Introduction

agriculture is that robots can work 24 hours a day – often when there’s no light, which
can be a big factor with certain crops.”
In this project we will be designing a multipurpose vehicle that will be able to plough the
land, sow the seeds, water the crops, level the land and carry out harvesting. We will be
using an android smart phone application to control the vehicle to respond to the control
signal. This type of vehicle should be useful for the farmers as a low investment option,
also for the ease of use and friendly user interface it provides. Instead of buying 2 or more
machines to carry out the various functionalities, the farmer can get his work done by
using our single efficient multipurpose agribot.

Agribot Introduction
Dept of CSE, NCET, Bengaluru 5 2015-2016
Agribot is deployed on a metal sheet developed with inbuilt roller and cultivator. The
front end of the metal sheet is given the harvesting feature, while both Water pump used
to water the crops and seed sowing will be added at the cultivator end. We use two motors
to control the forward, backward, left and right movement. One motor each is used to
control harvesting, seed sowing and watering the crops.
The working begins when the Farmer opens the application and can press the options
provided on the display screen. This android application is developed using Java. The
Bluetooth on the android phone will send the RF signals serially, on the other hand the
Bluetooth present in the robot will take actions according to the instructions given by the
Farmer. We use Embedded C and Keil Vision compiler. The Interfacing is done using
Microcontroller 8051.
The heart of our robot is Intel’s most powerful family of microcontroller 8051,we are
using AT89C2051 Two microcontrollers IC2 is first microcontroller which acts as master
controller decodes all the commands received from the transmitter and is responsible for
executing all the commands received from the remote and also generating pwm pulses for
the speed control .LD293 motor driver IC which drives two motors these two motors are
vehicle driver motors and it also runs the motors for all other attachments of agriculture in
the vehicle.
