This document discusses robotics, including defining robots, types of robots, components of robots, and the future prospects of robotics. It defines a robot as a machine that performs tasks normally done by humans. There are many types of robots including mobile, stationary, remote controlled, and virtual robots. The main components of robots are its structure, power source, actuators, sensors, manipulators, and locomotion systems. The future of robotics is promising with potential applications in healthcare, education, industry, research, and household assistance. Scientists project that highly intelligent robots may surpass human levels of intelligence within the next decade.

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.

Power Source.
Actuation.
Sensing.
Manipulation.
Locomotion.

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.
