1. Give a detailed description of the working of the attack and the defense
mechanisms on the robot.
Our project is an armed robot which is an extract of our team’s vision and knowledge.
This robot is the perfect prototype of a war machine, which is ready to annihilate the opponent
robot.
The bot includes an attacking mechanism such as cutting, pushing, and flipping, which
makes the bot a full-fledged armed robot to attack the robot.the size of the robot is 50*45*25.
CUTTERS: The bot contains two cutters which is projected out of the bot in the two directions
at an inclination ,the set up helps the bot to counter attack the opponents with its high speed
rotations with its sharp edge.
RAMP: On the front end of the bot, we have placed a ramp at an inclination of 30 degrees.
While the bots are engaged with one another, the ramp plays an important role, since the ramp
is down to the ground and has an inclination which enables the opponent bot to slide up onto
the ramp of the bot. The ramp has an open and closing mechanism, when the weight is
projected on the ramp, then the open mechanism gets activated and hits the bot back, so that
the opponent bot turns upside down, this makes the task easy to destruct the opponent.
DEFENDER: It is a defensive mechanism placed at the rear end of the bot. Its tactical
placement allows it to push/send enemy bots that try to attack.
NAILS: The top of the bot is covered with sharp nails which look like long sharp thorns that
strengthens the defensive mechanism of the armed bot.

Team work below mentioned the details of robot

2. Give a detailed description of the mechanism used for locomotion.
Motors are the heart of any working mechanism.
For the locomotion of the bot –
• Four motors , each having a torque of 5 kg and 300 rpm are used for the wheels of
the base.
• The two cutters on the either side of the bot are equipped with 3kg motor each, of
300 rpm.
• The defender at the rear end is equipped with a motor of 8kg torque and 60 rpm.
• The flipper at front consists of two motors each of 3kg torque and 300 rpm.
3. Give a brief account of your game plan and strategies. Describe how you plan to
make optimum use of the arena weapons. If possible, also post the link to videos
demonstrating the mechanisms you have built until now. Post your videos on You-
Tube and attach the link in the TDP.
OFFENSIVE AND DEFENSIVE GAME PLAN
When the game begins, the bot attacks the approaching opponent with the dual
side cutters tahat offer a torque of 3kg and rotates with 300 rpm. The cutters not
only attacks but also defends our bot by keeping the enemy bot at a safe distance.
The cutters are designed to function in such a manner that, when a single switch is
pressed, they start rotating at the same time, with the same speed.
On the front end, we have strategically placed a slope at an angle of 30 degrees. It
has a creative open and close mechanism which assists in pushing the opponent
bot away and more importantly it can also topple the enemy bot.
On the rear end of bot, we have placed a specially designed defence mechanism
called the “defender”. It is a strong iron plate of length 25 cm that can move in
a semi-circular anti-clockwise and clockwise direction and hence pushes away the
approaching bot.
Even if the opponent bot attacks from the top, the thorny shell of the bot can
defend the control system and the connections placed inside the bot as it is very
tough. The thorns can also damage the attacking weapon.

5. Describe how you propose to push the opponent’s robot (20-25kg) over the wedge.
When the opponents bot is in such a heavy weight also we don’t have any problem to
make his bot to move over wedge .
As we have placed the base motors of 5kg with 300 rpm and defending mechanism of
8kg10 rpm.
These motors give the maximum strength to push the opponent and we use the
technique of stability where we can make the half bot on land and push easily on straight
forward way or in side angles way towards wedge and reaming will be done by the arena
wepon.

4. When your robot gets pushed over the wedge and is toppled over/ is toppled over
by a flapper, describe the mechanism (if there) you will use to revert back once the
retries are exhausted or when it is toppled over by the opponent bot?
Our robot is designed in such a way that it has a large surface area of dimensions
50x45 sq. cm and a height of 30 cm. These dimension along with a net weight of 10 kg
offered by the bot provides a large amount opposing to the enemy robot.
Also we are using a high profile battery because of which the rotating motors can
negate the momentum offered by opposing/ pushing bots.
So its very tough for the enemy bot to push us off the wedge.
Also the large weight and momentum makes it tough for the flapper or the robot to topple us.

6. Give a brief account of the power supply and the controls being used. Give detailed
description of the controller in case of a wireless controller. (Channels, frequency
etc.)
BATTERY: The battery which we have used is a lead acid battery supplying 12 V and 7amp
current. The power source of the bot is off board and used for balancing the weight, The
battery connections are made properly to avoid short circuiting. All the wire connections inside
the bot are protected by the thorny shell.
SWITCHES: The whole bot runs under the control of the switches.
Two DPDT switches are used for the movement of the bot throughout the arena, these
control the four wheels in the base section.
Another DPDT switch is used for the activation of the movable ramp to open and close.
A single DPDT switch is used for the activating both the cutters placed on both the sides
of the bot.
Finally an another DPDT switch is used for the operation of the defender, placed at the
rear end.

7. Attach the images and drawings for the robot to give us a better idea of the proposed
mechanisms. (view 1)
step1 : an iron sheet is used as the base
Step 2 :cutting it to fix the base motors

Step 3 fixing base motors and front flipper , back defender .
Step 4 construction of cutter weapons and fixing it to robot

Step5 :Fixing of all parts of the robot

Step6: connecting wires for the motors and switches
Step7 completing the wiring connections and fixing of iron shield for the bot to protect .

Step8 : final finshing work with complete connections of wires, switches and battery

8. Attach the images and drawings for the robot to give us a better idea of the proposed
mechanisms. (view 2)
9. Describe any other mechanisms/details (if there) here
