3. ABSTRACT
 In the present days, number of situations exist where it is
not possible for a human operator to do an activity on
his/her own, due to a level of danger or difficulty involved.
 Employing robotic systems for performing difficult tasks,
rather than compromising on human lives.
 Here we propose to build a robotic arm controlled by
arduino uno.
 The development of this arm is based on Arduino platform
 A servo motor is a combination of DC motor, position
control system, gears.

4. Project Objective
 The main aim of our project is to build a robotic arm that can grip or
pick things .
 This project presents implementation of robotic arm that can be
controlled by arduino interface.
 Design and control of Robotic Arm using arduino.

5. TYPES OF ROBOTIC ARM’S :
 There are various ways in which a robotic arm may be
controlled.
 Typically, the following types of robotic arms are defined :
 Cartesian/Gantry Robot
 Cylindrical Robot
 Spherical/Polar Robot
 SCARA Robot
 Articulate Robot
 Parallel Robot

6. BLOCK DIAGRAM :

7.  What is ARDUINO ?
 The Arduino Uno is a microcontroller
board based on the ATmega328(datasheet).
 It has 14 digital input/output pins of which
6 can be used as PWM outputs.
 6 analog inputs, a 16 MHz crystal
oscillator, a USB connection, a power jack
and a reset button

8. ARDUINO BOARD

9. What makes a servo ?
Servo motors are constructed out of basic DC motors, by adding:
 some gear reduction
 a position sensor for the motor shaft
 an electronic circuit that controls the motor's operation

10. HARDWARE CONNECTIONS WITH
ARDUINO
The best thing about a servo motor is that it can be connected
directly to an Arduino.
 Connect the motor
to the Arduino
 Arduino with Simulink
program
 Arduino And Servo
Motors

11. How servo motor work’s:
• The third pin accept the control signal which is a pulse-width modulation
(PWM) signal.
• It can be easily produced by all micro- controllers and Arduino board.
• The control signal is fairly simple compared to that of a stepper motor.
• The pulse width sent to servo ranges as follows:
Minimum: 1 millisecond ---> Corresponds to 0 rotation angle.
Maximum: 2 millisecond ---> Corresponds to 180 rotation
angle.

12. Applications
 The robotic arm can be designed to perform any
desired task such as welding, cutting,picking and
packing
 In various industrial or home applications .
 Prototype of Bomb Disposal Bot.
 Used for Machine Tending
