ROBOCON DAIRY 2016 ~ 7 ~ Team Knight Rider
1. THEME, RULES AND AIM ' 16
1. 1 Game Concepts
At Present, we utilize the energies for several purposes in daily lives. The sources of all energies
are from nature. Human extract synthesize these energies from nature. Among all the energies,
fossil energy is among the cheapest and easily available. In the past, we misunderstood that fossil
energy had unlimited amount and superfluously consumed them. Our energy-consuming habit
from the past has affected us a lot this day. The sources of fossil energy are harder to explore.
The existing fossil energy will last not too long. In order to solve this problem, we have to
efficiently utilize the existing energy and at the same time explore and utilize alternative,
sustainable energy which should be clean and renewable in order to compensate the energy from
fossil.
1.2 The Importance of Safety
The participating teams, as the robot designers, are responsible for the safety of their robot. They
must work and cooperate closely with the organizers to ensure the utmost safety of the contest.
Team members must wear running shoes with rubber sole, helmets, and safety goggles during
the matches and test runs.

ROBOCON DAIRY 2016 ~ 10 ~ Team Knight Rider
2.2 Outline of the Contest
Each team consists of no more than two robots: one manual (Hybrid) and one
autonomous (ECO) robot . The Eco robot does not have any actuator to drive itself. To drive
Eco robot, driving force is indirectly getting from the hybrid robot, for example, solar energy,
wind energy, gravitational force, magnetic force, etc.
Eco Robot carries wind turbine propeller, and pass through 3 zone, 1) Hills and Slope, 2)
River, 3) Down Hills. In River zone, Hybrid robot does not enter, but it has to be given a indirect
power supply from remote zone. It must pass through zig zag, highland and down hills. At the
end of down hills Hybrid robot picks up propeller from Eco robot to enter into the start zone 2.
Once the hybrid robot in manual mode is transformed to autonomous mode, hybrid robot
carrying wind turbine propeller climbs the wind turbine pole and assembles wind turbine
propeller on wind turbine attached on top of the wind turbine pole.
The team that successfully assembles wind turbine propeller earlier is the winner of the
game. This type of winning is called " Chai-Yo".
2.3 Game Field: Structure
The field consists of a game area having the dimension of 14000 mm X 14000 mm and
surrounded by a wooden fence with the height of 100mm and the thickness of 50mm. The game
field is divided equally for two teams by a wooden fence with the height of 100mm and the
thickness of 50mm.
White lines with the width of 30mm made of non-shiny sticker is drawn on the floor of the game
area which are used to guide the motion of hybrid robot and travelling the path of ECO Robot.
The game consists of a "3 Slopes and Hills", "River", "Down Hill".
Hybrid Robot Start Zone 1: - “Hybrid Robot Start Zone 1” is a square area with the length of
1,000 mm each side. At the beginning of the game, Hybrid Robot has to stay in Hybrid Robot

3. A Glimpse of the Journey: An account of Robocons and its preparations
3.1 Before ROBOCON
Gujarat Technological University (GTU) Robocon Team selected through Written Test and
Personal Interview.
o Written Test
There are two separate papers for (Mechanical and Circuitix (EC/IC/EE/CE) branch)
Written test paper (75 Marks) consisted of 2 parts. The 1st part was completely based on
Rulebook and about Robotics (25 Marks) and the 2nd
part consisted of Basic Technical question
(45 Marks) for circuit branch Electronics, Programming, Digital Signal, Control System. While
for Mechanical branch CAD/CAM, Kinematics & Dynamics, Strength of Material, Vibration &
Balancing. The entire paper was MCQ based.
o Personal Interview
The selected students were interviewed one by one by the faculty advisor, Experts of Robotics
and Faculty member of the GTU. Detailed interview of every selected candidate and the panel
looked for every minute detail of the candidate ranging from Academic knowledge to the
enthusiasm for learning new things and readiness for working round the clock for the team.
3.2 Release of Problem Statement
The problem statement was released in mid-September. The primary task on our agenda was
discussing the design of our robots. The team was divided into groups of 4 (two each from
Circuitix and mechanical). Each team was expected to brainstorm all possible ideas and come up
with designs which were approved by both the departments in each team.
3.3 Design and Discussions
Gujarat Technological University, Team, 1
st time taking part in these types of national Robotics
event so Component selection and Design is the most crucial stage. A meeting was held every
alternate day all through the month of November to End of December.
ROBOCON DAIRY 2016 ~ 16 ~ Team Knight Rider
It was obvious from the problem statement that the Selection of Power transfer source from
Hybrid robot to Eco bot and design of Eco bot was the most crucial and that is where our
discussion begun. There was a general consensus on the use of wind energy source to transfer
power instead of any other alternate. So we set our target designs should be prototyped by the
end of December to gauge how far the wind force gave energy to Eco bot and the line following
in Eco bot.
In the early stages of design, when the problem statement was still being discussed, Hybrid was
considered to be the "easy" but, just mount four wheels and drive the robot.
We took the calculations at face value and considered only those mechanisms which seemed to
be feasible based on our calculations. Based on the discussions, team ordered some components-
motors, actuators, etc. - which fit our requirements.
Over here, we would like to mention one thing specifically- when deciding on the specifications
of motors, actuators, etc. it is necessary to arrive at decisions only after prototyping designs with
available equipment, not be calculations alone. As engineers, it is necessary that we are able to
observe from what we see in real and not depend on theoretical calculations -which involve lots
of assumptions.
3.4 ECO Robot Design
Objective
To design an Eco robot in such way that it can freely move on arena and it will not go down or
return back from the slope. And it has to follow the line so it can be easily controllable.
Iteration of ECO robot design
Majority of Mechanical design and change in Material were done in ECO bot.
Idea 1 :
First Eco bot were designed from PVC foam sheet, circular base and frustum in trapezoidal
shape was decided, while in electronics side two simple DC motor as free wheel, two robot
wheel and two caster wheel were used as actuators. To follow white line four line array sensor
(plus shape ) were used. But these design was failed because it cannot carry weight and air was
gone outside frustum.
ROBOCON DAIRY 2016 ~ 17 ~ Team Knight Rider
Fig: Pro - E Design 1 of ECO bot Fig: Testing of Pro - E Design 1 of ECO bot
Idea 2
To resolve the problem, to control air in one direction, different shape of frustums was designed
and tested. Finally, the conclusion is, large diameter circular shape frustum has capability to
control air in one direction. There is massive change in the design, Switch rectangular shape
from Circular based, circular frustum instead of rectangular or trapezoidal, Aluminum Material
used instead of PVC foam sheet.
As a result, we get the strength to carry weight and control air in one direction

Electrical Aspects (Components Used)
Microcontroller: For these competitions, open source microcontroller Arduino board was used.
Parallel programming was used, for that we established serial communication for communicating
between Arduino Mega and Arduino UNO. Mega was used to interface with the 15 LDR (Class -
2) sensors and send their data to the master whenever it ask for the data. While UNO was used to
interface with one servo motor for direction, purpose and two micro servo for breaking purposes.
Line follower Sensors: LDR sensors which give different analog values of different colors for
line following. Based on that value, Arduino controller gives the command to servo motor for
direction.
Motor Driver : The motor driver used for driving motors are L293D motor driver IC. These
could be used to drive two motors with a current rating of 1A.

3.5 Hybrid Robot Design
Objective
To design a Hybrid robot such way that it can carry power supply, actuators, and it also has a
mechanism to climb poles. The design arm such way, it can extend up to 1000mm to provide the
indirect power supply to Eco boat.
In parallel with the Eco boat design, hybrid boat design, and its electronics part was discussed to
get an idea of the type of sensors, wheels, arm mechanism that would be used.
Iteration of Hybrid robot design
Majority of Mechanical design changed in based and arm done in Hybrid robot.
ROBOCON DAIRY 2016 ~ 20 ~ Team Knight Rider
Idea 1
Initially, just after the problem statement for robocon 2016 was released, our initial thought was
the hybrid robot has functionality to carry all load, and able to extend its arm to provide wind
energy to Eco boat. First Hybrid robot design, was discussed on paper and designed in creo
software with consideration of all load calculation and other parameters.
As discussed in the meeting, C Shape is decided for hybrid robot, lower based is partially cut in
cross section at each corner while upper base is a rectangular cut with C Shape and 100 mm
omni wheel is mounted.
For robotic arm, total six link was designed, 3 links on the left hand side for transfer the wind
energy from hybrid robot to Eco robot and other 2 links on the right side for balancing purposes.
At the time of testing, this designer was not working properly.
During practice sessions, left side track and right side track, every time position of the link has to
change.
Handling of Omni wheel is difficult with a side cut section based

Idea 2
Second Hybrid robot design, was realized for fabrication to encounter problem faced in design 1.
This design was quite different from the first design. Designed hybrid robot with C shape
rectangular in both level and 100 mm mecanum wheels was mounted on the based while for arm,
3 link rack and pinion mechanism was discussed.
At the time of testing, this design was working properly to control robot, but during practice
sessions, a team facing a balancing problem and robot wheel was sleeping because of one side
rack and pinion mechanism.
Final Design
After being unsuccessful in getting balancing the wheel, sleep problem, third design was
realized for fabrication which is the combination of the first two designs.

Electrical Aspects (Components Used)
The PS2 Remote: To Control Hybrid robot
PS2 controller is used. This provided a better
speed control and enabled us to incorporate the
number of controls we needed for different
mechanisms. PS2 controller came as a savior
and proved to be one of the most fruitful things
we did in electrical point of view.
Arduino Platform: The Arduino Mega 2560 is
a microcontroller board based on the
ATmega2560. It has 54 digital input/output pins
(of which 14 can be used as PWM outputs), 16
analog inputs, 4 UARTs (hardware serial ports), a
16 MHz crystal oscillator, a USB connection, a
power jack, an ICSP header, and a reset button. It
contains everything needed to support the
microcontroller; simply connect it to a computer
with a USB cable or power it with an AC-to-DC
adapter or battery to get started.
ROBOCON DAIRY 2016 ~ 24 ~ Team Knight Rider
First, interfacing the PS2 remote control with it. One of the most precious features of the
Arduino platform was that of serial monitor. Now, joystick data value could be read on laptop
screen. DC Motor were interfaced with Arduino through Hercules motor driver. The code we
employed was so robust and detailed that it gave a clear error if the controller was not properly
connected. Pneumatic cylinder were also interface with the controller through the solenoid.
Interfacing the Hercules motor driver with Arduino
To drive DC geared motor Hercules motor driver were interfaced
with Arduino controller. PS2 Controller gave proper integers
ranging from 0 to 255, it was obvious to use serial
communication to give commands to the Hercules motor.
Mechanical
Pneumatic Cylinder
Pneumatic Control system high pressure air
could make the system faster and more reliable
than convectional motor drive system. In a
hybrid robot pneumatics were used for linear
movement for pole climbing. Three pneumatic
cylinders were used. The pneumatic cylinder
has a 12mm diameter provide stroke of
250mm. The pressure provided by the cylinder
was up to 6 bars. The bottle was preloaded in
the robots which was used for pole climbing.
Air Compressor
Air Compressor was used to store energy as a
compressed air in the pneumatic Cylinder and
with the help of a solenoid valve the cylinder
was closed. In a desire moment the valve was
set open and the energy of the compressed air
was released. This system was quicker and
efficient if could have done properly.
ROBOCON DAIRY 2016 ~ 25 ~ Team Knight Rider
Four Wheel Drive:
The holonomic drive system basically consists of
4 Mecanum wheels arranged in such a way that
the robot can be driven in all directions without
having to rotate the bot. These drives can have 2-3
configurations, one of which was used. While
implementing the four wheel drive the only thing
that was kept in mind that, it would be easily
controllable and to reduce the time.

4.4.2 League Match - 2 (4th
March 2016)
In League match 1, team faced the problem of wind energy, hybrid robot was not providing
sufficient wind energy to Eco bot so, we purchased new BLDC motor 2200kV, and fan size was
made 10 inches before the beginning of 2nd
match.
Match 71 Time 9:00 AM to 9.09 AM
In Second Match, GTU team played with Muffakham Jah Collage of Engineering & Technology,
Hyderabad. We did not score any point, due to some technical reason and during 2nd
League
match our team member touched the hybrid robot in field without taking the permission of the
referee. So, we were penalized by 5 points. It was heart-breaking, when we realized our
incapability to complete the tasks. On the brighter side, we did finish in the river zone in the
previous match and team performed well as the debut.

4.4.3 Things learnt from the robots of other teams
The team MIT Pune had used accurate line follower sensor. Their sensor change sensor color
when Eco bot pass from the different color area.
Muffakham Jah Collage and some other colleges use omni wheel for the braking system.

Learnt from ROBOCON 2016
The Experience of Robocon 2016 was something which shall always remain with us for our
entire life. Working in a team of 32 members with so much ecstasy and dedication was what we
enjoyed the most. Right since we received the problem statement, we were into it with full flow
and enjoyed every big and small milestone throughout the whole journey.
From the experience of Robocon, we conclude that in order to reach the higher
limits we always dream of, we should put in our efforts until everything is
complete and we should not get complacent just by reaching smaller milestones. We must realize
the importance of performance, and there are teams which work extremely hard, so to get at par
with them or beat them, we should work harder and get motivated by the final goal.
On the brighter side, team performed well as debated, and placed 1st Runner up among all
debut team and 51th
Rank among the 105 registered teams.
