This document describes a 3D printed robotic arm that is controlled using an Arduino board. The aim of the project is to build a robotic arm that can grip and pick up objects. The arm uses servo motors connected to the Arduino board to control the movement of the arm joints. Applications of the robotic arm include industrial tasks like welding and cutting as well as bomb disposal and machine tending.

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

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
