helped the participants understand how Lego Mindstorm
works and helped them when they had issues assembling a
Robot. After building the Robot, we helped teams connect it to
the computer using Bluetooth and USB connection. Then we
explained to them how the coding software of Ev3 worked and
how to use it. For demonstration, we taught them how to write
a code to make the robot move forward and backwards. We
taught them how to make the robot turn in all angles and asked
them to code the Robot to traverse in a square. After trying a
few times, they eventually traversed in predetermined squares
and then rectangles.

First, we used to have our parts printed externally by giving the
file to a different person and having them print it for us. We first
used resin printing as we thought it would be better. We soon
realised resin printing would be too expensive and the parts
would arrive slowly. We then shifted to FDM printing but still
got it done by someone else. There were still a few issues we
faced with this. If there was even one mistake in the design,
then it would be a failure and it would be too expensive to keep
printing parts. Eventually, we decided to buy a budget 3D
printer. Along with it we bought 1kg of ABS and PLA filament.
Now we could design many parts independently, print them
right in our work area, and get the details ready quickly. We
could easily modify parts and reprint them. We had to learn
about using the 3d printer before printing.
53

At first, we had trouble slicing 3D models after setting up our
printer, but we learned how to slice using recommended
settings in Cura. However, we faced several issues with the
printer, such as filament getting stuck or needing to adjust the
baby-step value. As we learned more, we could use advanced
slicing settings and even swapped out the nozzle for better
print quality. But then we ran out of PLA filament and switched
to ABS, causing more printing issues. We tried to fix the issues,
such as parts getting ripped off the bed, by putting tape on the
bed. However, we eventually ordered more PLA filament
because we couldn't figure out how to use ABS correctly.
54

To hold the battery to our robot, we needed a holder to store it
and help us attach it to the robot.
Version 1
After taking the battery measurements by scale, we started by
creating a sketch to be the base and then extruding the walls
and the base.
Then we made a slot for the wire of the battery to be able to
come out.
With the rough design of the battery holder down, we started
the refinement of the build and filleted down all the sharp
edges. However, if we were to re-design this part, we could
count this step as a mistake as we have learnt that it is better for
us to fillet the design at the very end since it becomes easier to
edit the part.
55

We needed the holes based on the goBILDA pattern to attach
the battery to our robot. So we took the step file of the 3-hole
plate from the goBILDA website. We made a slit on the side of
the battery holder according to its size and placed it in the slit.
We did the same for the other side and put our name on the
side of the battery holder.
While putting our name on the battery holder, we realised that
we couldn’t use a standard font as the inside of the letters
would fall out, so we installed a 3D font and used that to put
our name on the part.
56

Thus the first version of our battery holder was completed, and
we sent it for printing.
We then put another plate on the bottom for maximum
connection points. To do this, we first cut the side of the
container to make it fit in the base and then, like before, made a
slit and put the plate there.
57

Version 2
We realised that the battery holder was slightly wider than the
battery, so we had to make it smaller. We were not very
experienced with editing at this time, so we had many issues.
First, since we didn’t know about the timeline and how to use it
then, we used a highly complex method to make it smaller. If
we had to do it now, it would take barely 5 minutes since we
could use the timeline to modify the original sketch and then
modify the remaining features. But instead, at that time, we
tried extruding the walls. We had to delete all the fillets that we
made and then extruded the wall to match the bottom plate.
We had to take it back out and remove more of it to fit. Also, in
the previous model, the base plate had been too thin and
didn’t print, so we fixed that issue.
We also discovered that in our old design, the plate was
actually slightly extruding out in one place. We promptly fixed
this. And thus, the second model of our battery holder was
completed.
58

Version 3
We realised that the bottom plate of our design was pretty
messed up due to our inexperience.
To fix this, we remade the entire bottom and made it proper.
With this, our entire battery holder was completed, and we
could use it correctly in our robot and still use it to hold the
battery.
59

Version 1
To grab our cones we needed a claw for this we first took
inspiration from a design we found on the internet by another
team. We changed the claw to be better suited to our robot.
Their claw was also very complicated a hard to assemble. We
improved on this by changing the different parts of the robot to
make it easier to attach. Their claw also used a bearing we did
not have so we changed the mechanism of the claw to work
for our parts.
60

Version 2
In the original version of the claw, the servo would hit our cone
holder. So we redesigned it from scratch and also changed the
angles of the curves to better pick up the cones. We also
added holes in the claw where we could put elastic surgical
tubing for a better grip on the cone.
61

Version 1
We wanted our claw to be able to come out to grab the cones
from a distance. To do this, we used a slider to extend the claw.
We originally planned to use a thread and the standard
method to extend the slider. We realized, however, that it
would be too complicated to put two motors. So we instead
came up with the idea of using a gear rack and pinion to
extend it. First, we downloaded and modified a rack and pinion
mechanism from the internet. We made it to the sizes we
needed according to the goBILDA viper slider.
We then made the gear hole according to the REV shaft and
put holes in the gear rack to put screws to connect it to the
slider.
To allow a better connection to the slider, we set places for the
nuts to place the nut in the rack and then put the screw
through from the slider. Thus the first version of our gear rack
was completed.
62

In the subsequent few versions, we made minor changes, such
as adding four holes for the gear to connect better to the Rev
shaft. We also changed the gear rack style from standard to
herringbone. We also removed the holes since, in a
herringbone design, the gear would not move over the rack
properly if we added holes. We instead used 2 compound
glues to attach the gear rack.
63

Version 2
We wanted to increase the speed of the gear rack, but
doubling the size of the gear did not produce enough speed.
We decided to add a small gear between the gear and the gear
rack, and connect the large gear to the motor to further
increase the speed. However, we needed to create a mounting
plate to connect the motor and gears, which we designed
based on the measurements of the goBILDA U channel and
made precise holes for the core hex motor to fit.
Thus, the gear rack was fully complete.
64

We needed a properly designed holder for our cone so that we
could properly hold the cone, and it needed to be in such a
way that no matter how our claw dropped the cone, it would
still land upright in the cone holder.
Version 1
TTo make the base of the cone holder we took the
measurements of the cone and made a rough shape of the
cone holder. We made sure that near the top, the holder was a
lot wider than the cone so that it could receive the cone from
any angle. We added a little bump near the bottom to align the
cone into the holder properly. We also added an elongated
stick that could directly connect to our servo motor for us to
move the cone holder.
65

Version 2
The problem with this design was that the cone holder was a
bit too big and the cone could slip around inside it. So we
made the cone holder a bit smaller and changed the inner
bump from a round tip to a conical shape. We also removed the
connecting stick and instead burnt through holes for screws
near the top.
66

Version 3
Now we realised we needed an active locking mechanism
powered by a servo that would hold the cone in place so that
even when we made the cone holder upside down, the cone
would still remain in place and then we could navigate to the
junction and then release the cone. To do this, we first
considered having an arm near the outside of the cone holder
which would then push the cone inward. But after thinking for
a while, we came up with the genius idea of having the
positional bump be taller and then extending a mechanism
into the cone. We then had to think of what mechanism we
could use which would be so small but still be able to extend
properly. Our first idea was to use a gear rack and gear on the
inside which when spun would extend out and into the cone.
We thought that this was however too flimsy and the gear rack
would bend, and the cone would fall out. So we started
thinking of something else. Then we got the idea of using a
gear in the centre and two smaller wings on the side which
would extend out and block the cone.
67

We decided to go through with this design.
First, we needed to figure out a way to connect the servo to the
cone holder. To do this, we made a small plate near the bottom
to which we could attach the servo.
68

We made the inner part of the inside bump a shaft with teeth to
match the servo near the bottom.
We assembled the central gear onto the shaft, attached the
wings with pins, and created a cover at the top. We made sure
there was a hole through everything so we could attach a
screw to the servo. We also created a depression at the top to
avoid interference with the cone. To attach the cone holder to
the robot at an angle, we added an extension near the back.
69

Version 4
While using the locking mechanism for a while we realized that
the gears were breaking. We replaced the gears several times
but the small gears of the wings kept breaking. Thus we
realized that this mechanism was wrong and we couldn’t use it
with small and fragile gears. So we decided to revert to our old
design and started making that. We made the gear racks
according to the teeth of the gear and we made a small bump
on the gear rack to align it.
We then implemented this design and made other slight
modifications such as the connection point, the thickness, the
edges etc. They all are shown on the next page.

A few teammates started unboxing the kit on 6th December
2022. We removed the parts and kept them in a box. The
screws and Allen keys were kept separate. We also tried
figuring out how to make the base. We forgot to order some
motors, U-shaped channels, etc. So we had to order those
parts.
74

Version 1
First, the teammates connected 3 REV C Channels. Then it was
fixed using M3 screws. M3 is a three mm-sized screw. Soon we
realised that we had to make a goBILDA slider to fit the
mecanum wheels so that the robot could move sideways.
Hence we changed the entire chassis build to fit the mecanum
wheels, their respective gears and axles. We had to wait till the
second kit arrived. Till that time, the teammates tried making
the slider.
75

Version 2
Till this time, all the required stuff (gamepads, kits, DriverHub,
etc.) had arrived. We again gathered and started working. We
took 3 U-channels. 2 at the side and 1 in the middle. Two Quad-
block mounts were attached at either side of the middle U-
channel. Finally, all three were connected using M4 screws and
our chassis was 50% completed.
76

Version 3
We had invited Team Sigma 20890 to guide us in building the
robot. They told us to use a beam to support the chassis at the
front and the back to make the robot more stable. For this, we
used a C-channel. Some Make-X pieces were connected at
either slide of the C-Channel so we could attach them to the
end sides of the u channels. Finally, it was connected using
3mm screws.
77

Version 4
We realised that the robot was too long in terms of length. So
our coach took the robot to the metal cutting shop. Finally, the
extra metal on the front and the back ends were cut off. Those
metal plates were later connected to the middle U-Channel and
it was used as a base to mount the slider.
78

Version 5
Eventually, we ended up removing the gear rack which made
some of the supports of the chassis unnecessary. We could
have left the parts but they were heavy and slowed the robot
down a bit. We removed the heavy rev parts and added two
thinner and lighter parts. Their ends weren't matching with the
two main sides of the chassis so we attached one side each
and connected them with smaller parts. We also added two
handles like extensions to the sides of the chassis so that we
can carry it easily and our hands won't get hurt.
79

We didn’t directly attach the motors to the mecanum wheels.
We used a 90-degree gear, as mentioned in the manual. First,
the grub screws of the gears were loosened so the shaft would
go through them. Later they tightened again. We used two
gears, as shown in the picture below. There were a limited
amount of grub screws with us; multiple times, they loosened
and fell out of the robot. We realised that if this happened, we
wouldn’t have any more grub screws and couldn’t attach the
wheels to the motors tightly. Hence we used a medium-
strength thread locker to make sure that it would be less
probable that the grab screws would fall.
80

Version 1
We first used BWTlink sliders. They were supposed to be
better than GoBilda sliders as they were lighter and simpler.
We didn’t have the right screws for these sliders. To connect
these sliders, we needed flat-head thin M3 screws. We did not
have such screws, so we used tape to connect the different
sliders. We strung it normally, but the problem was that it went
slow because the sliders moved one by one. We realized that
we had to make all sliders extend simultaneously. Therefore,
some team members brainstormed but could not find a
solution. Hence, we learnt how to make a cascade system. We
found out that it needed multiple strings to make the slider
move simultaneously. Hence, we cut the long string into
smaller pieces. We faced many issues with the BWT sliders as
they were not properly attached due to the lack of screws. And
we couldn’t figure out how to attach the sliders properly to our
robot at an angle. We wanted to attach them at an angle as
that would make it possible for us to reach the high junction
without leaving the substation.
16 INCH
81

Version 2
Due to these issues, we got the goBILDA viper slider kit. We
used the 4-slider, 12-inch kit. While assembling them however
we faced an issue with stringing. We couldn’t figure out how to
use the cascade system in reverse. Since now the sliders were
at an angle gravity couldn’t pull them down we needed a
reverse cascade system to bring it back down. We tried a lot
and even read articles on it but just couldn’t figure out how to
use the cascade reverse system. So we, unfortunately, had to
revert to the linear stringing system.
82

Version 3
We realized that we didn’t need 4 sliders to reach the height of
the high junction. We also needed sliders for the horizontal
slider to extend the claw. We took off two of the sliders we also
added 2 springs to the top and the bottom of the slider. We
also changed the angle of the slider using a different rev part.
We also added a rev gear near the spool and motor so that we
can turn it by hand by holding the gear.
83

Version 4
Team Sigma told us that we didn't need two springs and that it
would be better for us to use 1 spring as then we could move
the slider by hand and it would make it less jerky. So instead of
using two springs, we used one spring with more tension. At
this time we didn’t put the string properly on the spring which
caused it to keep slipping off the spring. We had to learn how
to put the string properly. We also added one more slider as 2
sliders were barely enough to reach the high junction. The Rev
gear we had earlier attached to the spool was hitting the
ground junction and reducing the clearance of the robot. So
we replaced it with a gear print from earlier which we didn't
need anymore.
84

Version 5
While practicing driving, the cone holder got stuck at a
junction and we tried to free it, but accidentally snapped the
pulley string. In the past, we would have fixed the slider
mechanism by tying the same string and stretching the spring.
However, since we had recently ordered a new and stronger
string, we decided to replace it. Unfortunately, we had trouble
removing the spool because there wasn't enough space
between the end of the axle and the chassis, and there was a
gear in the way. Instead of disassembling everything, we
melted the gear to remove it. After fixing the slider and
restringing it, we discovered that the new string was too thick
and caused friction against another part of the slider. So we
replaced that part with a smaller one that could still function.
85

Version 1
A beam *(Make-X piece) was connected using M-3 screws on
the end of the chassis. A Servo Motor was mounted in the
centre of the beam. A 3-D printed claw was attached to a beam
that was attached to a servo. Also, a servo was placed in the
claw to grab and ungrab the claw.
*MakeX is a competition in which our team has participated.
Similar parts are used to build this robot as we used in MakeX
86

Version 2
Since we thought of using the racks, we had to remount them.
Now we had to use some spacers to hold the claw and its arm
at a small height. Two small plates were attached which were
used as stoppers. It was done to stop the claw arm which was
moving up and down, to drop the cone at the appropriate
angle.
87

Version 3
The claw wasn’t stable with one beam. So, we upgraded it with
2 beams attached to the claw on either side. The motor was
connected to both beams using the axle of the motor. Spacers
were used to hold the beams tightly. Some arrangement was
made using gobilda pieces to hold the beams.
88

Version 4
We also replaced the Core Hex motor (which moved the claw
up and down) with the Planetary gear motor. Now it was
running too fast. So, again it was replaced with an HD Hex
motor. Its RPM was 6000 which was too fast and would lead to
damage. We had to reduce it by using gears; 5:1, 5:1 and 4:1.
Now it reduced to 60 RPM. Also, the beam (Make-X part) was
replaced with a C-Channel to hold the motor which was heavy
as compared to the servo motor.
89

Version 5
As the gear racks were removed, we had to update the claw
holder. Two square plates were attached to the end of the
Chassis. The claw arm was attached with the help of the
spacers. A bracket was used to protect the HD-Hex motor.
90

We wanted to make something to move the claw forward so
that it can pick up the cone without entering the substation
during the autonomous period. We thought of this when
thinking about the autonomous period. After brainstorming,
we first thought of using a scissor mechanism. So the
teammates started thinking about how we can use it. It was too
complicated to design and print it. So our mentor told us not to
use it and use gear racks and move it forward by rotating the
gears
91

Version 1
We started by removing two sliders from our main slider and
attaching them to the top of the side panels of our chassis.
Soon we got 3D-printed gear racks and attached them to the
sliders. We attached them to the sliders by tape as the gear
racks and the holes in the sliders were not matching. Two
gears were 3-D printed on either side, and a core hex motor
helped to move the gear racks. A rod was used to hold both
kits. For attaching a rod, two stands were made stoppers were
placed on either side of a stand and on the motor to keep it
fixed. This version could have improved many things. While
some team members were programming, the rack was tough
to reset to its original position. Also, it was moving very slowly;
hence, it delayed in dropping a cone.
92

Version 2
We had to remove one of the goBILDA sliders for our vertical
slider. So we replaced the lost slider with a BMT link slider from
earlier. We figured out a screw to attach the slider to the U-
channel. One of the stands broke. Also, the gear design
needed to be corrected, as it resulted in the braking of the gear
racks. They were re-designed. We wanted our robot ready so
that Team Sigma could understand and give us tips. So the
racks and gears were redesigned.
93

Version 3
The normal racks were replaced with a Herringbone design to
move faster. These Herringbone design racks and gears were
3-D printed. Now it was moving a little faster. Also, the design
of the stands was replaced, they were made triangular.
94

Version 4
We didn’t get the appropriate speed that was required. It
needed an update so that the speed becomes faster. Therefore
the size of the gears was redesigned. Now their diameter was 3
inches. Also to make it stable, one more gear was used at the
end of a rack to hold it. The core-hex motor was replaced with
the planetary gear motor. Now it was running at the
appropriate speed that we need.
95

Now, we found that after picking the claw, the slider arm could
reach the pole. The racks were not used at all. We could also
pick the cone and drop it without the use of the gear racks
during the manual period. So we thought of deleting it from
the robot.
96

The power cables for the motors are connected to the
Expansion Hub. The claw, cone holder, and cone cup motors
are all connected to the Expansion Hub, while the slider and
claw arm motors are connected to the Control Hub. Previously,
the gear rack motor was connected to the Control Hub. The
Control Hub and Expansion Hub are connected using a USB
Cable. Additionally, a camera is connected to a USB port on the
Control Hub for autonomous periods.
We first thought of using the Control Hub to run the chassis
and the Expansion Hub to move the slider. While doing the
actual robot, the chassis motors were connected to Expansion
Hub. Encoders were used to get the exact position of the 4
motors.
Top Right Motor to Pin 0
Top Left Motor to Pin 1
Back Right Motor to Pin 3
Back Left Motor to Pin 4
The connections of the encoders of the motors are as follows:
97

The wires were messy and too long, so some were cut short.
The encoders kept getting disconnected, so they were fixed
with glue. The wires for the slider, claw, and claw arm were
covered with wire sleeves, but the slider sleeve kept getting
stuck, so it was mounted with a beam. The extra wiring for the
wheels was placed under the C-Channel and packed with a
plate attached to the claw. A REV Battery powers the robot and
a switch was mounted on the side of the slider using a plate. A
potentiometer was connected to the Analog pin of the Control
Hub to get the angle of the slider arm servo.
98

While the drivers were practising for the manual control period,
we found that the cone was getting stuck within the robot and
we couldn't pick another cone according to the Power play
rules (one cone should be picked at a time). Therefore we
brainstormed and found a solution. First we used a corrugated
plastic sheets. We draw the design and cut it off. With the help
of tapes, we stuck it. This part was looking ugly. So, we
decided to give it an upgrade by using acrylic sheets. First, we
mounted 2 small L-Channels on the side of the handles on
either sides. It was mounted to hold the filters. then 2
rectangles were cut-off from the sheet and they were mounted
on those sliders with the help of nuts and bolts. A custom
shaped filter was mounted with the help of tape and glue at
the front.
99

We first coded the initialising program for the motor movement
of the robot using joysticks. Without any function, it was like a
mess. Then we decided to use functions in our code to make
the code much more accessible, more reliable and more
understandable.
We gave the variables
to perform a certain
function such as:
TRP-Top Right Motor
TLP-Top Left Motor
BLP-Back Left Motor
BRP-Back Right
Motor.
101

‘X' button for picking and
dropping the cone in the
Low Junction.
'Y' button for picking and
Medium Junction.
'B' button for picking and
High junction.
The first code is of the main
function and the second one
is of the auto function. Then
we used the joystick buttons
to move everything from
taking the cone and placing it
in the high junction. We used
condition statements to check
whether the gamepads'
buttons are clicked. We
decided to use:
We tried it for many days
because there were a lot of
problems. We needed to
change the values, again and
again, because we didn’t
know the main cause behind
the fluctuating values.
102

We now learnt that if the battery gets low, the speed of the
motor gets low too. So, we couldn’t rely on time. Then we used
in-built motor encoders instead of time, but couldn’t neglect
time because we need a delay before every function. If we
didn’t add a delay then the robot might have itself damaged.
But still, we were not using time for moving the motors and
only using it for the delay so there was no problem. Also, the
gamepad was facing issues because we were using all the
movements on the same gamepad.
103

During the Sigma team meetup, they suggested programming
separate buttons for each function. This would allow us to use
the dropping arm to properly place the cone if it wasn't placed
correctly in the holder. Initially, we reduced the workload to
one gamepad and split the functions equally between both
gamepads. The Sigma team also taught us how to program the
encoders. While the movement code remained the same, they
advised us to change the code for picking up and placing
cones in the junction. They assigned the second controller as
the function controller and the first as the movement controller.
In the second controller, we programmed the functions for
grabbing and placing cones.
104

We added Zero Power Behavior for the brake.
Driver 1 and Driver 2 functions in the main code . Code in
Driver 1 is as same as earlier but was only to the Driver 1

‘X’ for Claw Up.
‘B’ for Claw Down.
‘DpadUp’ for Slider Up.
‘DpadDown’ for Slider Down.
‘DpadLeft’ for Dropping Arm Up.
‘DpadRight’ for Dropping Arm Down.
But first, we made different functions for driver 1 which is
gamepad 1 and for driver 2 which is gamepad 2 for making the
code more understandable. Then we called the function in the
main code.
112

After that, we were doing the manual practice but the claw was
not properly placing the cone in the cone holder (bucket for
holding the cone). After a few days of working on the robot, the
Claw Servo got jammed because of too much pressure
applied. We realised that the servo was overused even if the
claw closed. This caused the servo to jam. We replaced the
servo.
We replaced the Claw Hand Servo with a Core Hex Motor and
programmed it, but the inbuilt encoder of the Core Hex Motor
was not accurate and kept changing values. We tried using a
potentiometer, but even its values kept changing, so we
replaced it with a Bore Encoder which worked properly.
However, the Slider motor overheated due to overuse, similar
to the Claw's servo.
113

After a few days, the team decided to change the hardware.
We Added a locking system in the Cone Holder (which was
controlled by the servo) so that it can hold the cone once the
slider is extended.
‘X’ for holding the cone
‘B’ for releasing cone
Auto-locking code when dropping arm is going up.
Auto unlocking code when dropping arm is going down.
114

Auto-locking code with dropping arm up when the slider is
going up.
Auto-locking code with dropping arm up when the slider is
going down.
We added an auto-locking system so that when the slider goes
up the locking system locks the cone and when the slider
comes down the locking system unlocks the cone and falls in
the junction. While changing the mechanism, the build team
rewired everything. The wires were wrongly attached, so the
robot was not sliding properly. Without realising changing the
whole code. After we realised the problem, we changed
everything to normal. The wires were rewired, and we spent
nearly three hours figuring out the problem and we fixed it. We
calibrated each motor properly and it worked.
115

Machine Learning
The FIRST Tech Challenge Machine Learning toolchain (FTC-
ML) allows us to create custom TensorFlow models for the
game challenge. Machine Learning can use them to detect the
signal sleeve and other game elements incorporated in the
autonomous code using Vuforia.
When we first tried ML, we trained the model on a cube for
testing.
116

It could have been more accurate, seeing we had prepared it
for 200 steps to save on the minutes used.
After this, we trained on the red cones for 200 degrees; Our first
strategy was to position our robot according to the cones in
the autonomous period.
A block in ML gives us the angle to the cone from the robot;
negative means the cones are to the robot’s left, and positive
means the cones are to the robot’s right.
Our strategy was positioning the robot in the center and then
moving towards the cones.
To move towards the cone, we were going to use the
“regonitionHeight” block.
117

We figured out where the robot needed to be to catch the
cone correctly.
But this didn't work as we realized the “regonitionHeight”
block distance values are not proportional.
Our code also used to get stuck in loops since we didn’t know
back then how to use while loops in blocks correctly.
After this, we realized we didn’t need ML to position the robot
to the cones. Instead, we needed it to recognize the signal
sleeve for parking.
We started working on an entirely different strategy. We
decided to try parking with the help of the custom-designed
sleeve, as it would give us 20 specific points shortly.
Then we will start increasing the complexity of the robot.
118

So we began by designing the signal sleeve, and came up with
a design.
We then trained the first sleeve model,
112
119

But there was a big issue, The model wasn’t working!
We tested it on the example code we can get on the
programming page while creating a new op Mode.
After debugging hours, we realized we did not label a few
hundred frames.
So we re-trained the model with all of the videos fully tagged.
120

We printed our signal sleeves on poor-quality paper, but then
our mentor suggested printing them on vinyl for better quality.
After printing six copies on vinyl, we realized that we needed to
retrain our model because the vinyl had a different finish,
making it challenging for TensorFlow to detect it with our
previous model.
We trained the model in the afternoon, but in the evening, it
stopped working due to the glossy, shiny finish of the vinyl
causing detection issues in certain lighting conditions.
We decided to shift back to paper sleeves since they
responded better to different lighting conditions.
The code we made is displayed on the next page.
121

We first were going only to use seconds bases programming.
But we quickly realized this was not going to work out.
So our first strategy was to use external encoders.
But this was hard for us since we would either not have a part
or the part needed to be the correct size.
So we decided to use internal encoders for the movement of
the robot.
All codes are displayed on the next page.
To start it we stop and reset the encoders of the movement
motors,
Then we set the target position to 1075 * tiles.
Then we set it to Run to Position. The logic for running the
motor is if the current position isn't in 10 to 15 ticks of the
current position then it runs the motors but if it is it stops the
motors.
Similarly, we have used this logic for moving backwards
forwards and sideways.
For turning we were first just going to use the encoder like we
are for moving, But we quickly realized this wouldn't work
since the robot would be too fast and would overshoot.
So we used the gyro of the IMU
124

7th-14th November, 2022
Team Legogoa has officially
commenced its preparations to
participate in the Worlds largest
Robotics competition FIRST Tech
Challenge India under the banner
of FIRST Tech Challenge. The
team is named as Legogoa Axi0m
and has 15 students from all over
Goa. We started off with formal
introduction of all the team
members and their parents
followed by presentations by
team members on what FTC
means to them. The item on
agenda for this week on raising
sponsorships to fund the team
activities.Various roles were
assigned to each parent of the
team members. The first
successful meeting was
concluded with snacks and
photo sessions.
127

15th-22nd November, 2022
During this period, we mainly
focused on skill-building. Team
Sigma was teaching us CAD
(Computer aided designing)
using an app called OnShape. We
learnt the importance of CAD,
and we also came to know how
we will use it in the competition.
We were given various CAD
assignments so that we could
improve our CAD skills. In CAD,
we learnt to use multiple parts
such as Fillet, Chamfer, Sweep,
Loft, Revolve, Extrude, etc. We
were also introduced to the Rev
website during our training, and
we learned more about the parts
of FTC and its uses. We were also
involved in making our team's
logo for the FTC competition.
There were almost 20 logos
designed by our team members.
We were also involved in
developing the website for
fundraising purposes. Many
could learn more about FTC and
its fundamental importance
through the website.
128

23rd-30th November, 2022
We were focusing on the type of
programming to be used: Block-
based or text-based. Since we are
a Rookie team, our coach
approached Block-based. During
these days, we were learning how
to use Onshape-Computer Aided
Designing. During this period,
many were practising CAD by
making various designs. Also, we
all sent our details(achievements,
bio, etc.). During these days, we
were also finalising our Team
logo. We were trying to create a
simple logo with very few
elements, a deep meaning, and
signifies something about Goa
and the club Lego Goa. The team
members created 20+ logos.
129

1st-7th December, 2022
Finally the kit arrived in the first
week of December. We enjoyed
unboxing the kit and had alot of
fun. We also learnt FTC sim. FTC
sim introduced us to some
fundamental programming
challenges and helped us
understand the robot's
movement. We got a basic idea of
how the robot would move using
the FTC sim. We were also
introduced to the colour sensor
section in the FTC sim. Our
website also went live during this
period. We were also tasked with
submitting the certification on
Onshape. Everybody was also
charged with presenting so that
our mentors got to know how
much we understood about FTC.
We also got a few funds for the
competition and planned on
starting outreach activities. We
also conducted a workshop on
4th December and we managed
to raise Rupees 6000 through the
workshop.
130

8th-15th December, 2022
We finally started working on our
documentation and also the
build. Team members built the
1st version of the slider. We
started to attach all of the slider
parts with a string. (Thread) After
this, we realized that how the
threading was done, made the
sliders come one after the other.
This made it slow. We wanted all
sliders to move together to make
it faster. So the team members
tried using physics to understand
the concepts of pulleys. After
brainstorming they came up with
the idea of threading which made
all the sliders go up together.
Then a few members got
together and started building and
threading. Our first version was
made of Rev Parts. Team
members also worked on the
daily presentations. We made
high progress in building and
raised money through our
outreach this week.
131

16th-23rd December, 2022
Brainstorming - is the only word
this week could be described in.
Our coach told us that we have to
strategise on how to hold our
cones. A few team members
immediately started the work on
designs. Some notable ideas
include an arcade toy grabber
claw or a diamond shaped claw.
Most of these ideas were given
keeping in mind that the cone
would easily fit in them. We
celebrated a robotic-themed
birthday of our team member
Shounak. Our team coach
Saieesh Sir introduced us to
GitHub and we had our first
training session with Shri Anay
Kamat. GitHub is a platform
where a team can collaborate on
website development and it
keeps a record of contributions
and changes made. During the
session, we built a small website
using HTML and learned the
basics of GitHub. We were also
made aware of the different
awards that could be won by us
this season. We understood the
importance of documentation.
Grateful to the guidance of an
external instructor.
132

24th-31st December, 2022
FTC Team LegoGoa Axiom was
the first customer for a 3D
printing lab and requested the
lab to 3D print a claw for their
robot. The lab staff explained the
3D printing process to the team
and they learned about the
advantages of 3D printing, such
as reducing the number of molds
needed to make a part and
decreasing fabrication time. The
team was also able to introduce
the concept of FIRST to the lab
staff and Shri Rohan Khaunte
Honorable Minister of IT for the
State of Goa presented the team
with the 3D printed part. Team
Sigma 20580 declared the results
of a claw design competiton that
was hosted by them a week back.
We had a major outreach
planned for the new year ie. on
31st Of December. It was at the
Innovation Hub, Goa Science
Centre. We were busy in
preparations for that. We also
created an instagram page to
promote the activities that we do
and also to show our progress.
133

1st-7th January, 2023
New Year Began with the second
day of the workshop at
Innovation Hub. We started to
design our website using a tool
called Github. We also started
working on the robot's
programming, such as the robot's
controller, and on the manual
code for the gamepad. Another
workshop was conducted on 2nd
January for fundraising purposes
and one to create awareness of
various national and international
competitions. The robot-building
process had already begun, and
the main parts of the robot, such
as the claw, were already 3D
printed. We also started working
on the slider and the pulleys. The
robot was being built bit by bit.
During this week, a mentor of
RoboFunLab RFL Mumbai
guided us on the domain of
documentation that included the
engineering notebook and
portfolio.
134

8th-15th January, 2023
Our GitHub website and robot
build was upto mark. The camera
was helpful as it could score
points by detecting the cones
through the machine learning
programme. Now we started
working more on programming
and focused on improving our
autonomous navigation and
machine learning. After the
testing the robot, we started
working on our strategy for
scoring points and posting daily
blogs on the GitHub website.
Although many challenges were
faced while building the robot,
and solutions to them were found
easily by us. The week ended
with a photoshoot of all the team
members.
135

16th-23nd January, 2023
CAD and FTC sim were mainly
revised and practised during this
week. The build team watched
videos of the FTC robot so that
we could learn more about robot
building and implement the ideas
in our robot. We were focused on
the build, did various things such
as tightening the tyres and
working on the claw, and worked
on the design to fix the distance
between the cone and junction
problem. Many of us were also
learning about programming and
watching videos on machine
learning and autonomous
navigation. We were working on
the encoders as we weren't using
odometry. We even worked on
the engineering notebook.
136

24th-31st January, 2023
Our 3D printer arrived during this
week. Apart from that
preparations were on to welcome
Team SIgma to Goa. They
assisted us as we were a rookie
team and they were a veteran
team. A 3-day workshop
conducted by Team SIgma gave
us useful tips about FTC. They
helped us with the robot build
and solved our problems with
programming, documentation,
field setup, and the game
element. The most remarkable
advice they gave was on scoring
points and strategy-making. At
night we had a scrumpcious
dinner with them. There were
also team bonding sessions
conducted by Ms Karuna
Satardekar. It was an honour
having Shri Rohan Khaunte IT
Minister Goa concluding
ceremony. We were greatful that
he posted on his social media
channels about our workshops.
This workshop was covered by
Goa's leading newspapers.
137

1st-7th February, 2023
We followed team sigma's advice
on our robot. We learnt a bit
about scouting. We wrote blogs
on the 3-day workshop and
posted them on our website. We
rebuilt the robot based on the
suggestions of Team sigma to
remove the shortcomings
pointed out by them. We also
changed the claw hand servo to a
core hex motor because of
weight and trained the ML model.
We also learnt a bit of scouting.
We focused on the engineering
notebook and also made a lot of
progress on the engineering
notebook because of Team
sigma's advice.
138

8th-15th February 2023
The programming team did many
things, such as coding the
autonomous cycle of picking and
dropping the cones and also
manual gamepad programming.
A potentiometer was also added
to the claw hand for more
accuracy via the encoder values.
The slider motor overheated
once, and we realised that our
code was putting too much
pressure on the motor causing it
to overheat. The servo motor of
the claw hands broke as the gear
teeth inside the motor were
smashed. We then studied what
caused it.The reason that the
code tried to close the claw more
than physically possible leading
to motor overload everytime it
was used. During this week our
game elements arrived after a
long wait.
139

16th-23rd February 2023
The claw more than physically
possible leading to motor
overload everytime it was used.
During this week our game
elements arrived after a long
wait. Some of the team members
conducted another workshop for
the underprivileged at Hamara
School, Goa. Thus creating
awarenesss about robotics and
coding to the weaker sections of
the society.
140

24th February-3rd March, 2023
It was the last week of the FTC
season 2022-23 preparations. We
concluded our outreach sessions
by hosting a robotics workshop
for the specially-abled kids. That
same afternoon we also
participated in the science fiesta
at the Goa Science Center and
gave a demonstration on our
escapade through FTC. The next
day the team geared up to go to
Chorao Island for our final
outreach. It was a fun journey as
we had to cross the River
Mandovi to reach there. We
convinced a few school students
to form a team for the next FTC
season. The last week was a real
roller coaster ride for our team as
our slider broke, and we had to fix
it. The ML team had also given
their efforts to finish the Signal
Sleeve Detection Model. As we
completed the robot build, the
building team focused more on
documentation. A minor issue
was faced every time we
practised, so we had to fix them.
Another disaster we faced at the
end of this week was that our REV
Control Hub Failed.
After contacting
REV support we
tried to resurrect
the robot, but that
failed. So we tried
to ask for help, and
luckily we ordered
a new REV hub.
141

Going to the Terminal at the end as scoring cones or owning a junction is
much more effective. If the other team starts trying to make a junction, we
immediately get their area's ground junction. However, if they get one of
their junctions, we take the other one to block.
NOTE : All are under BLUE
Strategy Number 1
143

First, one of the robots places a cone on their circuit junction to block
them. Then we split the role of Capturing High-Junctions between the
two of us teams, and we go for one high junction while the other team
goes for the other high junction. Then as soon as the game ends, we cap
both Junctions left for the opponent with a beacon. It means they can't
use the junctions near them while we can. While doing this, our partner
team will split from us and go for capping medium and low junctions to
earn points while we focus on the same high junction.
Strategy Number 2
144

At the start of the manual stage, TeamPlacer will go for high-blue and use
quick placing strategies to secure many cones. Meanwhile, TeamSpeed
zips around the arena and conquers mid and low stations for points. They
will also dominate the ground station near red. Once the end game starts,
Team Speed will place both beacons on High-Red, High-Up, or High-
Down.
Strategy Number 3
145

At the start of the manual stage, TeamPlacer will go for high-blue and use
quick placing strategies to secure many cones. Meanwhile, TeamSpeed
zips around the arena and conquers mid and low stations for points. They
will also dominate the ground station near red. Once the end game starts,
Team Speed will place both beacons on High-Red, High-Up, or High-
Down.
Strategy Number 3
146

The two teams in our alliance will be divided into Team A & Team B, Team
B is the faster team that can zip around the area fast. Team A is the slower
team that can place cones faster. Once the manual starts Team B will
immediately go to claim g-t-l to block Red’s Circuit. Team A will get g-b-l
to start our circle. From here the First Stage of the mission will begin.
Stage Circuit. For Stage, Circuit Team B has to claim G-t-r, l-uu-r, g-u-m,
and H-U.Meanwhile Team A will claim g-b-l, l-mb-l, M-b-l, H-L and M-t-
l.Once this is completed The main stage starts.
During this stage, Team B will zip around capturing all Middle low, and
high junctions for ownership. Team A will focus on getting H-l and spam
cones on it. Then comes the stage Endgame: During this stage, Team B
will retake all junctions lost in the circuit and Team A will place both
beacons on High Junctions.
Strategy Number 4
High Junction (h) if left high junction
then called high left, (h-l)
Medium Junction (m) if
right then called medium
right (m-r)
Low Junction
has the same
naming trick.

conduct workshops : Guru Pawaskar, Santosh Naik Raikar, Rukmi & Uday
Dangui and Milind Subedar.
151

Import of Components from USA and Clearance from
Customs & Excise Department, Government of India:
Several components had to be imported from the USA for the fabrication
of the Robot. Any item imported from foreign into requires clearance from
the Customs & Excise Department, Government of India. The clearance is
a process by itself, and the imported items are released for usage only
after the complete satisfaction of the C&E Department. The releasing of
the components imported by Team LegoGoa Axion was a challenge in
itself, and the Government officials at the C&E had to convince the usage
of these components in India besides completing all formalities for the
release of the components. Imported parts include :
153

Conducting of Awareness Workshop programmes as
part of the Outreach programmes:
Goa is one of the smallest states in India with limited avenues to conduct
activities related to Outreach programmes. Conducting such workshops
was a challenge for the team due to the limited resource availability. As
the knowledge was limited amongst the students in the state of Goa,
Team LegoGoa Axion decided to carry out workshops across the State.
The activity would require publicity, venue and other resources,
participation, etc. Team LegoGoa Axiom successfully conducted such
workshops across major towns in the State of Goa besides in several
schools mostly in the Rural part of the State. The students were thrilled
with the workshop as it provided a briefing about the programming of the
Robot, live demonstrations and hands-on experiences. The team also
conducted workshops in the schools for specially-abled students and
underprivileged students.
154

Problems with Building and Coding
The Team faced numerous challenges while building and coding the
Robot. The Team had members located across the State of Goa. Each
member or group of members were assigned separate tasks. There
needed to exist perfect coordination among all the members for the
proper execution of the project. It was also needed that the team
members met frequently for building the Robot. All challenges faced by
the team members were resolved to the best of the knowledge of all the
participants sometimes with the help of the mentors or information
available online.
155

Control Hub Failure
The Control Hub failure just few days before the competition was the
major challenge faced by the Team LegoGoa Axiom. The team spent over
12 hours trying to debug the issue including connecting to Rev support
and following their instructions to reset the control the hub OS to rule out
software issues. It was finally concluded that the issue was with the
Control hub hardware. Shipping a new Control hub from USA would be
time consuming. Considering all the efforts put by the team and the
limited timeline available for shipping of the hub, the Team mentor made
an appeal to FTC India community to invoke Gracious Professionalism to
help out with ideas, advice or spare control hub to enable the team to
participate. The team finally arranged for the Control Hub by purchasing
the same from a vendor from Pune associated with FTC.
156

Conducted
By
Ms.
Karuna
Satardekar
Ms. Karuna Satardekar is an associate professor at GVMs Dr Dada Vaidya
College of Education Ponda Goa. She conduct workshops for in-service
teachers, students, NGO and self-help groups on different topics of life
skills. She is certified trainer of Junior Chamber International (India) and
helped Team Legogoa Axiom by conducting “Team Bonding Session”.
She helped us to know more about each other. She planned many great
games and taught us to play them.
158

In this game, we had to form two teams and each team had to stand in
line. Everyone had to be blindfolded except the last person at the end of
the each line who is the team leader. There were some bottles kept on the
floor. There is a bag kept at the starting point in which you need to put
maximum bottles. The two teams discuss and plan their strategy. The
team leader controls his team. We had code words like “Push” means go
forward, “Pull” means go backwards and “Shake” means the first person
has to bend and pick the bottle. The team which puts the maximum
bottles in the bag which is kept at the starting point wins.
159

The second game is where Mrs. Karuna Satardekar divided us into
two teams and formed two circles. She gave each team a sheet of
paper with brain teasers. We had to discuss together and find the
answers of the brain teasers. The team with the most correct
answers wins.
Then Mrs. Karuna Satardekar formed two lines and announced
numbers. Each number had a specific action to perform. She said
some number and when each number was spoken we have to do a
specific action like: Number 1: Give a high five Number 2: Scream
Legogoa Number 3: Turn around
