This document describes designing and developing a robotic arm using servo motors controlled by an Arduino Uno microcontroller. The robotic arm uses 4 servo motors to control each joint and imitate the motion of a human arm. The arm is physically controlled, with the signals replicated by the microcontroller to synchronously control the servo motors of the robotic arm. The objectives are to help disabled people perform tasks independently and to use such robotic arms for applications like automated manufacturing and bomb disposal.

3. To design and develop Robotic arm using servo motors with the help of AT Mega 328P
Micro-Controller(i.e.Arduino Uno R3 Board).
The principle of motion Imitating Robotic Arm is a to control rotation of servo motor
using a voltage divider through variable resistor .
AT mega 328P micro-controller is used to read analog values and convert them into
them into pulse width modulation to control angle rotation angle of servo motor.

4. Our Project is a Arduino based Robotic arm capable of imitating its human arm. It
uses of 4 servo motors that control each joints and arm its motion.
This arm is generally controlled by physical means.The Physically controlled arm
functions as an analog input to the system , which replicates and records the signal
and synchronously functions with the servo motors ( i.e.:The Robotic Arm)

5.  Robotics is a Special Branch of Engineering which deals with electronics,
designing, programming and building it up.The motive behind designing this
project was exploring the different fields in robotics and in software domain. It is
made using Open source electronics prototyping platform. Another motive was of
making the valuable knowledge of robotics meet the need of people and help
them explore the wisdom of life.
 Many times, people affected from polio, major accident in which person lose their
arms, person affected paralysis so they become disabled physically to their
regular work.To overcome their disability we can use robotic prosthetic arm.
 The main motivation behind this project is to help out physically disabled people
to unleash their own potential with robotic prosthetic arm rather than simple
prosthetic mechanical arm.This project will provide a new approach for physically
disabled people to live with harmony so that they could do their work by
themselves without relying on other people.

6. The Objective behind the project is as follows:
1) To minimize efforts of physically disabled people so that could do their work as
normal people .
2) To make use of such arms as prosthetic arms or legs to the humans as well as to
the animals.
3) To Make use of Robotic Arm in automated Manufacturing Assembly lines used in
factories.
4) To make use of Robotic Arm to diffuse and test explosives in army applications.
Robotic arm are also used in army to diffuse land mines .This saves life of soldiers
from being injured from explosion.
5) To minimize cost of product materials to build prosthetic arm.
6) To make use of open source electronic prototyping platform like Arduino boards so
that cost is minimized and its free for future modifications.

7. Defence Packaging systems
Automated Manufacturing Assembly Lines. Prosthetics arm design.

8. 1) Variable resistors will be connected to Arduino as per circuit
diagram.
2) Necessary Programming will be done logically fit our
application requirements.
3) Output will be measures in terms of motion in combination
of working of different servo simultaneously.
4) Accuracy and Precision in robotic arm will verified and
tested after designing frame for robotic arm.
