2. What Is Robotics...?
Robotics is science of designing or building an
application of robots. Simply ,Robotics may be
defines as "The Study of Robots". The aim of
robotics is to design an efficient robot.
Why Is Robotics Needed...?
Robotics is needed because:
 Speed
 Can work in hazardous/dangerous temperature
 Can do repetitive tasks
 Can do work with accuracy

3. History of robotICs
The word 'robotics' was first used in
Runaround, a short story published in 1942,
by Isaac Asimov.
But it was not until 1956 that a real robot
came into existence.
 The earliest robots as we know them were
created in the early 1950s by George C.
Devol
Isaac Asimov

4. Three Laws of Robotics
The Three Laws of Robotics (often shortened to The Three Laws or known as Asimov's Laws) are a set
of rules devised by science fiction author Isaac Asimov.
First Law
A robot may not injure a human being or, through inaction, allow a human
being to come to harm.
Second Law
A robot must obey the orders given it by human beings except where such orders
would conflict with the First Law.
Third Law
A robot must protect its own existence as long as such protection does not conflict
with the First or Second Law.

5. ROBOTICS TECHNOLOGY
Most industrial robots have at least the following parts:
 Manipulator : Main body of robot (Links, Joints, other
structural element of the robot)
 End Effecter: The part that is connected to the last joint of
a manipulator.
 Actuators: Muscles of the manipulators (servomotor, stepper
motor, pneumatic and hydraulic cylinder).
 Sensors: To collect information about the internal state of the
robot or To communicate with the outside environment.
 Controller: Similar to cerebellum. It controls and coordinates the
motion of the actuators.
 Processor: The brain of the robot. It calculates the motions and
the velocity of the robot's joints, etc.
 Software: Operating system, robotic software and the
collectionof routines.

7. MOBILE ROBOT

8. INDUSTRIAL ROBOT
Most of these robots perform repeating
tasks without ever moving.
Most robots are working in industries.
Especially dull and repeating tasks are
suitable for robots.
A robot never grows tired; it will perform
its duty day and night without ever
complaining.

9. ALPINE SKI HOUSE
AUTONOMOUS ROBOT
 Autonomous robots are self
supporting.
 They run a program that givesthem the
opportunity to decideon the action to
performdepending on their
surroundings.
 At times, these robots even learn new
behavior. They startout with a short
routine andadapt this routine to be more
successful at the task theyperform. The
most successfulroutine will be repeated.

10. REMOTE-CONTROLLED ROBOT
Complicated tasks are still best
performed by human beings with real
brainpower. A person can guide a
robot by remotecontrol. A person can
perform difficult and usually
dangeroustasks without being at the
spot where the tasks are performed.

11. ALPINE SKI HOUSE
VIRTUAL ROBOT
 Virtual robots don't exits in real life.
Virtual robots are just programs,
building blocks of software inside a
computer.
 A virtual robot can simulate a real robot
or just perform a repeating task.
 Search engines use such kind of robots.
They search the World Wide Web and
send the information to the search
engines.

12. ADVANTAGES
 Going to far away planets.
 Going far down into the unknown waters and
mines where humans would be crushed
 Giving us information that humans can't get
 Working at places 24/7without any salaryand
food. Plus they don't get bored
 They can perform tasks faster than humans
and much more consistently and accurately.
 Most of them are automatic so they can go
around by themselves without any human
interference.

13. DISADVANTAGES
 People can lose jobs in factories
 It needs a supply of power
 It needs maintenance to keep it running .
 It costs money to make or buy a robot
