3. • Robotics
• Why Robotics?
• Types of Robotics
• Laws of Robotics
• Components of Robots
• Advantages
• Future Prospectus
• Smoke Sensor
• Queries

5. • THE WORD “ ROBOTICS ” IS USED COLLECTIVELY TO
DEFINE A FIELD IN ENGINEERING THAT COVERS
THE MIMICKING OF VARIOUS HMAN CHARACTRISTICS
• SOUND CONCEPT IN MANY ENGINEERING DISCIPLINES IS
NEEDED FOR WORKING IN THIS FIELD
• IT FINDS ITS USES IN ALL ASPECTS OF LIFE

6.  A Automatic Industrial
machine replacing a Human
In Hazardous ways.
 An Automatic mobile sweeper machine
at modern home.
 An Automatic toy car for children to play
 An Machine use for spying or safety purposes.

7. ROBOTICS INCLUDE A KNOWLEDGE
OF MECHANICAL, ELECTRONICS,
ELECTRICAL & COMPUTER SCIENCE
ENGINEERING.

8. THE TERM ROBOTICS WAS COINED IN 1940s BY SCIENCE FICTION
WRITER ISAAC ASIMOV
ASIMOV’s LAWS OF ROBOTICS
 A robot may not injure a Human Being OR, THROGH, INAACTION,
allow a Human Being to come to harm.
 A robot must obey the orders given it by Human beings except where
such order would conflict with the first law.
 A robot must protect its own existence as long as such protection does not
conflict first or second law.

10.  Speed.
 It can work in Hazardous/Dangerous Environments.
 To perform repetitive task.
 Efficiency.
 Accuracy.
 Adaptability.

11.  Wheeled
 Legged
 Climbing
 Flying

12. o Structure.
o Power Source.
o Actuation.
o Sensing.
o Manipulation.
o Locomotion.

13. • The structure of Robot is usually
mostly Mechanical & can be
called as kinematic chain
• The chain is forms of link‟s (it‟s bones),
actuators (it‟s muscles), and joint which
can allow one or more degrees of freedom.

14.  Suitable power supply is needed to run the
motors and associated circuitry.
 Typical power requirement ranges from
3V to 24V DC.
 220 AC supply must be modified to suits the
need of our machines.
 Batteries can also be use to run the robots.
 Robots are driven by different motors :-
o DC Motor.
o Stepper Motor.
o Servo Motor.

15.  Actuators are “ muscles “ of
a robot, the parts which convert
stored energy into movement.
 The most popular actuators are
electronic motors.

16. • Robots which must work in the real world
require some way to manipulate objects;
pickup, modify, destroy, or otherwise
have an effect.
• Thus the „hands‟ of robot are often refereed
to as end effectors, while the hand is refereed
as to be manipulation
• Some Manipulators are :-
• Mechanical Grippers.
• Vacuum Grippers.
• General Grippers.

17.  It is concerned with the motion of the robot.
 Robots contain different types of drivers :-
Differential drive
Car type.
Skid steer drive.
Synchronous drive.
Pivot drive.
Articulated drive.

18. 1. Revolution in Health care Medical Science system.
2. New & wide scope in Education & Training.
3. A Good help in Nuclear Industry.
4. Used tremendously in Sports activities.
5. Can very well handle House hold business.

19.  Scientists say that it is possible that robot brain will
exist in 2019.
 Vernor Vinge has suggested that a moment may come
when Computers & Robots are smarter than Human.
 In 2009 some robots are acquired various
forms of semi-autonomy, including being able to
find power sources on their own.
 The ASSOCIATION FOR THE ADVANCMENT OF
ARTIFICIAL INTELLIGENCE has researched on
this problem.

20. • When smoke is present in the gap of the photo interrupter
module, the light beam from LED to the phototransistor
is obstructed. As a result, the phototransistor stops conducting
and pin4 (reset) of IC 555 goes high to activate the alarm.
• The photo transistor and LED must be housed inside an
enclosure with holes to allow entry of smoke.
• This smoke detector circuit project require a power supply
between 9 and 12 volts .
