Acknowledgement
First we would like to express our greatest gratitude to the Almighty for giving us a chance
to complete the project without whose blessings it would not have been possible. We would
like to acknowledge our professor Ekta Singla. We are very thankful that he supervised our
work and provided with the much needed assistance in understanding the project. Without
her guidance we might not have been able to achieve the goals of the project. Beside this
we would like to thank lab assistant of Robotics Lab who literally helped us to a very large
extent and without his aid we wouldn’t have been able to shape up the project in this
manner like we had now. Apart from this we would like to thank our institution for
providing a state of art facility laboratory equipped with all the instruments required for the
project and we don’t think we will be able to do justice if we don’t mention our batch-mates
who did help us at different stages of the project.

Abstract:
In our project we have concentrated on some special type of problem which is the problem
of entering the person with shoe where shoes are not allowed. It can be converted to some
other applications also because this is made in such a way that it is easily convertible with
other application. The main motivation behind this project is give a proper shape to this
problem which is more effective than just putting a paper and saying shoes are not allowed.
It is best fit way to coming modern world to control this type of problem.
Introduction:
Robotics is big area which includes lots of technologies. These technologies deal with
automated machines that can take the place of humans in different environments or
manufacturing processes, or resemble humans in appearance, behaviour, and cognition.
Many of today's robots are inspired by nature contributing to the field of bio-inspired
robotics.
There are lots of problem which are required automation with some beautiful environment
creation. We have selected one of the problem which is generally faced in some restricted
area where shoes are not allowed but even in that case also people ignore the rules and any
written statement and enter that particular area without removing shoes. This is also faced
in individual homes in which people enter into the clear area without considering any
problem. So this problem should be solved in such a manner that is does not harm anyone
but try to restrict the person or giving some idea of importance of cleanness at that field.
We have chosen dog as bio-inspiration. Because the dog is considered as the best option for
activity related to door. Giving any restriction using dog at the door is not considered as
weird this is the best part of idea of using dog. Also it supports the modernization of our
society. This should also be used friendly.

Parts Used:
Arduino: It is an open-source computer hardware and software company, project and user
community that designs and manufactures kits for building digital devices and interactive
objects that can sense and control the physical world. It is mind of whole computer. It takes
signal from computer then gives to motor.
Dc Motor: A DC motor is any of a class of electrical machines that converts direct current
electrical power into mechanical power. The most common types rely on the forces
produced by magnetic fields. Nearly all types of DC motors have some internal mechanism,
either electromechanical or electronic, to periodically change the direction of current flow
in part of the motor
We have used two dc motors which are attached to the front legs to give motion.

Speaker Module:
In this we can save any kind of voice and then we produce that using loudspeaker. In our
case we just adopt the voice of the barking dog which will create a environment suitable for
our target.
Design And Working: It has 4 lags but only front two legs rotates to give motion in front
direction other two are just give the particular height. In the down section a of dog height
support is used which gives less friction because of the point contact section.

Whenever a black shoes is brought in front of camera it detects that using matlab code and image
processing then it is proceed to the arudino which is mind of the whole system then it decide what
to do next as the already installed program. According to required decision dog starts barking and
creating forward motion toward the man which enters which the shoes and which is recognized.
Safety Issues:
Description of Risk Possible
consequences
Prob. of Risk Severity
of Risk
Overall
Risk
Contingency Plan
1.Motor Failure It can stop
somewhere
where it can get
damaged
M M M We can make a another mode in
which another motor is attached with
relatively easy working
2.Misguided By
Similar Target
It can leave its
path without
giving any
problem signal
L H H We need to make some better
images processing for unique feature
of dog
3.No differentiation
Between shoes and
other black objects
Reaction toward
the black shoe
and black other
obstacles may be
dangerous
M L M We need to make some extra if
conditions to make system better
differentiator.
4.Less space and
suitable path
Available for Robot
It may happen
that dog cannot
cross the some
section through
which main is
going
M M M We can decide our robot size in such
a manner that it can pass through all
possible paths in the way.
5.Instant Change In
Environmental
conditions
Change in
conditions can
harm the robotic
dog.
L M M Robot should have sensor which can
detect the change in environmental
conditions like rain etc.

Conclusion
This type of model gives the acceleration to the speed of modernized world because it creates a
environmental of creating biomimetic situation not just the forcing statement and all that. This can
be used for other purpose also because it has the speaker module which is of multi voice recording
system. Best part of this is that its controls the situation or timing according to the requirement as
included in our programing. Safety consideration of this design so attractive because it does not
have any hazard that is greater than the medium level.
