NEED OF PROJECT

Extensive applications in hazardous conditions

Replaced massive human work force

Areas of application:

Medical science

Surgeries

Defense

Artificial intelligence

We extended applications of robotics

To use in industries for purpose of picking and

placing objects

To use it in case of wars

To pull out casualties from war front

Autonomous robot that could reach far and wide

This gave birth to surveillance pick and place robot

GENERAL DESIGN

Defined as mechanical design capable of

performing tasks in human like manner

Requires expertise and programming

Sub systems

Pick and place robot has an arm and a

wireless camera

Serves the purpose of surveillance

AIM

Thus a machine that is

Compact

Rugged

Efficient

Capable of pick and place

Operate from a remote place

Controls motion of robotic arm

STEPS OF IMPLEMENTATION

Designer needs to be fully aware of

system requirements

Process begins with hardware design

o Mechanical design assembly

o Stable structure capable of bearing load

Electronic circuit is designed in ‘eagle’

o Microcontroller is chosen

o Circuit designed around it

Implementation of code

o Code is compiled using ‘KEIL’ compiler

Code tested on simulators

o Adjustments made on code

o Removal of errors

PCB for the main board is etched

o Components are mounted

o Soldering is done

Testing of entire system

o Put through tasks

o Performance parameters are observed

o System checked for faults

SOFTWARE ASPECT

Q. WHY KIEL?

ANSWER:

For coding the CPU, we have utilized the KEIL software.

It enables the programmer to use high level languages

such as C to code the microcomputer.

KEIL encases and supports a well equipped chip library

from a variety of manufacturers.

It supports various register architectures which can be

incorporated in the code by including a header file.

PCB DESIGNING

Easily Applicable Graphical Layout Editor(EAGLE)

APPLICATIONS:

Military applications Surveillance device

To pull out casualties

Can be used to transport objects just

on a click of a button

Industrial applications Loading of objects

Serving security purposes

Surveillance

Reaching places out of human reach

ADVANTAGES:

Wireless

Simple design

Reliable

Easy up gradation

Organized control

Thermal Overload Protection

Short Circuit Protection

Output Transistor Safe Operating Area Protection

L293D LINE DRIVER

600mA Output current capability per

channel

Over temperature protection

Logical “0” input voltage up to 1.5 v

Internal clamp diodes

High voltage, high current four channel driver

Accepts TTL logic levels

Drives inductive loads (DC motors)

Each channel has enable input

Suitable for use in switching applications at

freq up to 5 KHZ

PIN CONNECTIONS

Microcontroller insufficient to drive

motors

L293D consists of array of darling ton

current amplifiers

It helps to boost supply to motors

INTERFACING OF L293D WITH MICROCONTROLLER

DC MOTORS

Low torque and high speed devices

Gear set can be used to increase torque at the

cost of speed

The movement of shaft is smooth

Easiest to operate

Can rotate in both directions

Thus speed needs to be controlled to handle it
