3. Introduction
 One of the biggest and common needs of today’s world is the machine which
reduces the human efforts and increases the speed of work and also of low
budget.
 This requirements led the manufacturers’ to manufacture quality and cheap
product .Scientist and manufacturer are trying to develop such machines which
are capable of carrying out tasks with the help of some supervision and they are
getting into more and more demand.
 They are trying to minimize errors as well as to have experienced and well
trained employees for quality products.
 The important component part of automation system is Robot. In this project,
we have tried to make machine, which are operated with the need for human
assistance in advance also have been made to operate spontaneously without the
need of human power with the progress of technology like microcontroller and
programming machines.

4. Design
 The robotic arm for this project is the revolute type that closely resembles
the human arm.
 Shoulder that mounted on base can remove the arm through 180 degrees,
from horizontal to vertical on each side. The shoulder uses large-scale servo,
provide the torque needed to lift the rest of the arm, as well as any object
that it may be grasping. Attached to the shoulder piece is an elbow that can
move through 180 degrees, also powered by a large-scale servo. The wrist is
made up of one standard servo and can move through 180 degrees.
 The gripper is made of the metal and wooden body. Gripper is controlled by
the one single servo motor. It helps the gripper to pick any particular
object. As our project was on basic level the gripper is able to pick only
regular shapes like sphere , cube, cuboid, pyramid etc.

6. Working
The receiver and the transmitter pin of the Bluetooth model are connected to
pin 0 and pin 1 of Ardiuno Uno respectively and the GND and Vcc pin of the
Bluetooth module is connected to the GND and 5V of Ardiuno respectively. The
GND and Vcc of all the servo motors is connected to the common GND and Vcc
from the Arduino. The signal pins of the
servo motors are connected to
pin 3,5,6,9,10 and 11 of
ardiuno which are the digital
pulse width modulation(PWM)
pins in the ardiuno UNO.

 The Android app is used to transfer the
information from android device to the
bluetooth module with the help of android
application.
 The Bluetooth module transfers the
received signal to arduino uno.
 Arduino uno passes the information to the
servo motors and the servo motors are
driven accordingly.

8. Programming and Android App
8
ANDROID APPLICATION:-
The Android application we used in this project
was done with App Inventor. App Inventor is a free
web application developed by Google and later
developed by the Massachusetts Institute of
Technology (MIT).In this project the MIT app inventor
is used to design app to control 6 servo motors using
android device and Bluetooth module.
ANDROID PROGRAMMING:-
Programming is done using C language on
Arduino application available on Computer.The
code is written in accordance to the Android
application

10. Conclusion
 In this project we are designed a 6-DOF manipulator robotic arm and has
been successfully completed.
 With reference to many available manipulators and mobile platforms in
market, a practical design for the manipulators has been perceived and
computer aided designing tools like AutoCAD are used to model the
desired manipulators.
 Theoretical analysis of the inverse kinematics was carried out due to
determine the effectors position and orientation. Final analysis done by
practice application of arm in various situations .

11. Future scope
 Autonomous robots using the artificial intelligence can replace humans in
any field of work such as medical , industrial and military .
 A number of initiatives around the world are underway to create robots
that act as health care aides or personal "butlers.“
 Exoskeletons allow users to augment their physical strength , helping
those with physical disabilities to walk and climb , it also finds application
in the military
 Body-machine interfaces helps amputees to feed forward controls that
detect their will to move and also receive sensorial feedback that
converts digital readings to feelings .
 Telepresence robots act as your stand in at remote locations saving
business travelers both time and money .
