CHAPTER 2
2.0 Project Work Done During Internship
During the period, I handled industrial based projects like 3D Printer, NRF based communication
system, Arduino & ESP8266 based Quadcopter, Smart Air Purifier and some other automation
based on IoT like universal remote & home automation. Also designed some professional Printed
Circuit Boards(PCBs).
2.1 Obstacle Avoiding Robot
Obstacle Avoiding Robot is an intelligent device which can automatically sense the obstacle in
front of it and avoid them by turning itself in another direction. This design allows the robot to
navigate in unknown environment by avoiding collisions, which is a primary requirement for any
autonomous mobile robot. An Ultrasonic sensor is used to sense the obstacles in the path by
calculating the distance between the robot and obstacle. If robot finds any obstacle it changes the

direction and continue moving. The application of Obstacle Avoiding robot is not limited and it
is used in most of the military organization now which helps carry out many risky jobs that
cannot be done by any soldiers.

2.2 NPK Detection of Soil
This project aims at developing a high cost-effective method to detect the presence of Nitrogen
(N), Phosphorus (P) and Potassium (K) of soil. Also measure the other parameters of soil like
Moisture, Temperature & humidity. This can improve the quality of soil and reduces the
undesired use of fertilizers to be added to the soil. These three elements nutrients promote the
growth of the plant in different ways Nitrogen promotes the growth of leaves and vegetation,
Phosphorus promotes root and growth and Potassium promotes flowering, fruiting and keeps
regulation of nutrient and water in plant cell. we are using optical transducer method for
detection of Nitrogen, Phosphorus & Potassium of soil. The optical transducer was formed by the
integration of light transmission system and light detection system. The Arduino microcontroller
was used to operate the light source in a transmission system. Apart from that, it was also used as
a data acquisition from the light detection system, light transmission system utilized three LEDs
with different wavelength. Each of the LED was chosen according to the spectrum absorption
wavelength by the NPK soils.

2.4 Wi-fi Based Quadcopter
Every quadcopter comes with a microcontroller board with sensors on it, in our case – the
Arduino board. I chosed Arduino Uno because it cheap and easy availabe in market.
Arduino uno work on Atmega328p microcontroller which is 8 bit microcontroller have enough
processing speed and Clock Speed 16 MHz, Can provide 8-bit PWM output with the
analogWrite() function.
This board, together with the components choose, controls the motors. It is up to you to choose
how self-controlling you want your quad to be, and you can use only the basic ones such as the
gyro, or a bunch of other, more advanced sensors such as barometer, or a GPS, or even a sonar
so that your quad can be able to detect and avoid obstacles that are in its way. In this quadcopter
I used ESP-01 as a receiver and smart phone as transmitter or controller. For programming and
calibration of quadcopter I used multwii firmware which is easy to use because of its graphical
interface.

CHAPTER 3
3.0 Conclusion
On the whole, this internship was a useful experience .I have gained new knowledge, skills and
met many new people. I achieved several of my learning goals, however for some the conditions
did not permit. I got insight into professional practice. I learned different facets of working
within a Roboslog Pvt Limited.
Along my training period, I realize that observation is a main element to find out the root cause
of a problem. Not only for my project but daily activities too. During my project, I cooperate
with my colleagues and operators to determine the problems. Moreover, the project indirectly
helps me to learn independently, discipline myself, be considerate/patient, self-trust, take
initiative and the ability to solve problems. Besides, my communication skills is strengthen as
well when communicating with others. During my training period, I have received criticism and
advice from engineers and technician when mistakes were made. However, those advices are
useful guidance for me to change myself and avoid myself making the same mistakes again.
Apart from that, I had also developed my programming skills through various programs that I
had done. The activities that I had learned during industrial training really are useful for me in
future to face challenges in a working environment. Throughout the industrial training, I found
that several things are important:
 Critical and Analytical Thinking

19
To organize our tasks and assignment, we need to analyze our problems and assignment, and to
formulate a good solution to the problem. We would have to set contingency plan for the
solution, so that we are well prepared for the unforeseeable situations.
 Time Management
As overall technician and programmer are always racing against tight timeline and packed
schedule, a proper time management will minimize facing overdue deadlines. An effective time
management allows us to do our assignment efficiently and meet our schedules. Scheduling
avoids time wastage and allows us to plan ahead, and gaining more as a result.
 Goal Management
Opposing to a Herculean goal seemed to be reachable at first sight, it is better to sub-divide the
goals to a few achievable tasks, so that we will be gaining more confidence by accomplishing
those tasks.
