The Word Robotics is Used To Collectively Define A Field In
Engineering That Covers The Mimicking Of Various Human
Characteristics.
Sound Concepts in Many Engineering Disciplines is Needed
For Working in this Field.
It Find Its Uses In All Aspects Of Our Life.

4. * DEFINITION OF A ROBOT
• "A reprogrammable, multifunctional manipulator
designed to move material, parts, tools, or
specialized devices through various programmed
motions for the performance of a variety of tasks" Or
a simpler version.
• An automatic device that performs functions
normally ascribed to humans or a machine in the
form of a human.

5. *
An automatic industrial
machine replacing the human
in hazardous work.
An automatic mobile sweeper
machine at a modern home.
An automatic toy car for a
child to play with.
A machine removing mines in a
war field all by itself and many
more….

6. * THE PURPOSE OF ROBOTS
 Repetitive tasks that robots can do 24X7.
 Robots never get sick or need time off.
 Robots can do tasks considered too dangerous for
humans.
 Robots can operate equipment to much higher precision
than humans.
 May be cheaper over the long term
 May be able to perform tasks that are impossible for
humans

7. *THE PURPOSE OF ROBOTS(cont.)
Dirty Tasks
 Repetitive tasks
 Dangerous tasks
Impossible tasks
 Robots assisting the handicapped.

8. 
It is a field of engineering that covers the
mimicking of human behavior.
. Robotics includes the knowledge of Mechanical,
Electronics, Electrical & Computer Science
Engineering.

The term robotics was coined in the 1940s by science.
fiction writer isaac asimov.
Asimov‟s Law of Robotics:
A robot may not injure a human being, or through inaction ,
allow a human being to come to harm.
A robot must obey the orders given it by human beings excepts
where such order would conflict with the first Law.
A robot must protect its own existence as long as such
protection does not conflict with the first or second Law.

Collision avoidance is somewhat different from
collision detection.
Possible collisions will depend on the shape and size of
both the object and robot as well as the position and
motion.
When making an attempt to avoid an obstacle, there are
many decisions to face.

The structure of a robot is
usually mostly mechanical and
can be called a kinematic
chain.
The chain is formed of links
(its bones),actuators(its
muscles),and joints which can
allow one or more degrees of
freedom.

23. *
Suitable Power Supply Is Needed To Run The Motors And
Associated Circuitry.
Typical Power Requirement ranges from 3Vto 24V DC.
220V AC supply must be modified to suit the needs of our
machine.
Batteries can also be used to run robots.
Robots are driven by different motors:-
DC motors
Stepper Motors
Servo Motors

24. *
As the name suggests, a motors which uses a DC(Direct
Current) power.
Can run in both directions.
Speed controllable

25. *
Used For Measured Rotation.
Can Be Held At A Particular
Position Of The Shaft
Ideal For Many Autonomous
Robots Requiring Higher
Precision.

26. *
Used in closed loop control
systems in which work is the
control variable.
An integral feedback
deceive(resolver) or devices
(encoder ) are either incorporated
within the servo motor or are
remotely mounted , often on the
load itself.

27. *
Actuators are the “muscles” of a robot , the parts which
convert stored energy into movement.
The most popular actuators are electric motors.

28. *
Robots which must work in the real world require
some way to manipulates objects ; pick up ,modify,
destroy, or otherwise have an effect.
Thus the „hands‟ of a robot are often referred to as end
effectors ,while the arm is referred to as a manipulator.
Some manipulators are:-
Mechanical Grippers.
vacuum Grippers.
General purpose effectors.

29. *
It is concerned with the motion of the robot.
Robots contains different types of drives:-
*Car type .
*Skid drive.
*Pivot drive.
*Articulated drive.

30. *
Revolution in medical science and health care systems.
New & wide scope in Education & training.
A good help in Nuclear industry.
Used tremendously in sports activities.
Play the role of an efficient assistance in Research and
Development sciences.
Can very well handle household business.

31. *
Scientists say that it is possible that a robot brain will exist by
2019.
Vernor Vinge has suggested that a moment may come when
computers and robots are smarter than humans.
 In 2009,some robots acquired various forms of semi-
autonomy, including being able to find power sources on
their own.
The Association for the Advancement of Article
Intelligence has researched on this problem.
