The document discusses the definition and history of robots and robotics. It defines a robot as a machine that can perform tasks in place of humans, especially dangerous tasks. Robotics is the study of designing and building robots. The first uses of modern robots were in factories during the industrial revolution. The word "robot" was coined in a 1920 play by Karel Capek, and the word "robotics" was defined by Isaac Asimov in the 1940s to describe the field of robot study. The document also discusses Isaac Asimov's Three Laws of Robotics and the typical parts of industrial robots.

2.  A robot is a re-programmable,
multifunctional machine that is designed to
replace human in hazardous work.
 Usually it is electro-mechanical machine .
 A machine resembling a human being and
able to replicate certain human movements
and functions.

3.  Robotics is science of building and designing
applications for robots.
or
 Robotics is the branch of technology which
deals with the structure ,making and
applications of robots.
 A very simplest definition could be “Study of
Robots is called Robotics ”

4.  The history of robots belongs to ancient
myths and legends.
 The first uses of modern robots were in
factories as industrial robots – simple fixed
machines capable of manufacturing tasks
which allowed production without the need
for human assistance.

5.  The word robot was introduced to public by
Czech writer Karel Capek(1890-1938) in his
play R.U.R (Rossum’s universal Robots),
published in 1920. The play begins in a
factory that makes artificial people called
robots. Capek was reported several times a
candidate for Nobel prize for his work.

6.  The word “robotics” used to describe the field
of study , was defined by the Russian –born .
American scientist and science fiction writer,
Isaac Asimov (1920-1992) in 1940s.

7.  Robotics is important because of :
• Speed
• Accuracy
• For hazardous places work
• For doing a task repetitively

8.  First Law : A robot may not injure humanity,
or through inaction, not allow humanity to
came to harm
 Second Law : A robot must obey orders given
by human beings , except where such orders
would conflict with a higher order law
 Third Law : A robot must protect its own
existence as long as such protection does not
conflict with a higher order law

9.  Most industrial robots have at least five parts
• Sensor
• Effector
• Actuators
• Controllers
• Arms

11.  Advantages :
• Going far away on planets.
• Going far down into the unknown waters and mines where human
would be cursed
• Giving us information that human can’t
• Giving at places 24/7 without any salary and food. Plus they don’t
get bored
• They can perform tasks faster and accurate
• Mostly don’t need human help
 Disadvantages :
• People can lose jobs in factories
• It needs supply of power
• It needs maintenances to keep it running
• It cost money to make or buy a robot
