CE 2.2 Project Background
CE 2.2.1 Characteristics of the project
The outline of the framework engineering must consider the accompanying perspectives
Robustness and execution; cost; measure; control prerequisites; weight. An individual depiction
of each detecting framework is given along these lines, yet despite the particular properties of
every framework, it is imperative to consider the autonomous vehicle all in all as opposed to as
an amalgamation of sensors. In such manner, a lot of thought must be given ahead of schedule in
the outline procedure to how the greater part of the sensors and actuators shape a special body,
much the same as the human body. In spite of the fact that field vehicles can be huge, lodge
stend to be brimming with gadgets, levers and controls without much space to save, so it is
fundamental to design proficiently and, for instance, blend the data from a few sources in to a
solitary screen with an unmistakable show and inviting interfaces.

CE 2.2.2 Objectives developed for the project
The main objective of this study work is to design and develop a low cost Auto-Steering
System for an agricultural tractor in the laboratory.
1. To conduct extensive review of autonomous agricultural vehicles especially
agricultural robotics using artificial intelligence devise based on Microcontrollers and GPS.
2. To design auto steering system based on reference set point instead of GNSS includes
linear variable deferential transformer, hydraulic actuator, solenoid control valve, relief valve,
hydraulic pump, steering wheel, LCD Screen and microcontroller.
CE 2.2.3 My area of work
I have designed several autonomous parts of the off road vehicle which are also made for
the designing of the main system which is based upon the auto steering mechanism. I have also
understood all the concepts and the mechanism of the systems and I have also understood about
the functioning of the system. I have designed the sensors and the transducers for the system.
After completion of this project I have created the documentation and I have collected all the
information from several study and internet.
CE 2.2.4 Project Group
I have done this project under the supervision of my project guide and he has helped me a
lot in making this project. There were also several engineered in the mechanical department who
have also introduced me with several instruments and their mechanism. I was also thankful to all
those employees and the project manager of the company for assisting me in the project and to
teach me a lot.

CE 2.2.5 My responsibilities throughout the project
I was responsible for making the design and the functionality of the system and the main
concept related to the system. I have also responsible for any kind of errors present in the system.
I have also implemented the main concept of the system and the outline of the student. I had the
responsibility to prove the assurity of the information which I have used in this project.
CE 2.3 Distinctive Activity
CE 2.3.1 Comprehending the theory of the project
The multifaceted nature of the wise framework does not really need to be made an
interpretation of in to the lodge controls, and it ought to never be overlooked that the last client
of the vehicle will be an expert rancher, not an aircraft pilot. The physical places of the sensors
and actuators are additionally basic to guaranteeing an effective plan. One of the primary slip-
ups made while arranging a robotized vehicle that is proposed to wander in the open field is an
absence of thought of the unforgiving condition to which the vehicle can be uncovered: frigid
temperatures in the winter, motor and street vibrations, grating radiation and temperatures in the
late spring, solid breezes, high stickiness, dew and unpredicted downpours, tidy, grating from
branches, introduction to splashed chemicals, and so on. These conditions make rough terrain
vehicle outline unique, as it veers from exemplary mechanical applications where portable robots
are outlined to work inside. In the event that unwavering quality is the principle worry, as
already talked about, hard product continuance is then a critical issue. Not just must the gadgets
utilized be of high calibre, yet they should likewise have the correct insurance and be situated
ideally. Much of the time, putting a fragile piece in a fitting position can shield it from
unpleasant climate and hence expand its working life. It demonstrates a robotized tractor with a

portion of the standard frameworks that include keen vehicles. I have composed a few self-
sufficient parts of the rough terrain vehicle which are additionally made for the outlining of the
principle framework which depends on the auto guiding instrument. I have additionally seen
every one of the ideas and the component of the frameworks and I have likewise comprehended
about the working of the framework. I have composed the sensors and the transducers for the
framework. After consummation of this undertaking I have made the documentation and I have
gathered all the data from a recent report and web.

system and the basic idea of the mechanism are also discussed in this project in order to make the
system more advanced.

2.3.4.1 Issues
The lessening of capital info has dependably been a basic issue for farming. A great deal
of the industrially accessible direction frameworks are extremely costly to be of down to earth
utilize what's more, execution, and are for the most part suited to specific needs. Worldwide
