2.  What is robotics.
 History of robotics.
 Mechanism of robotics.
-locomotion of robot.
-power supply system
-actuators.
-control system.
 Type of robots by application.
 Conclusion.

3.  The word robotics is used to
collectively define a field in
engineering that covers the
mimicking of various human
characteristics.
 The word robot comes from the
Slavic word robota, which is
used to refer forced labor.
 The desired task must be
achieved within some given
limitations.

4.  The word robotics was derived from
the word robot, which was
introduced to the public by Czech
writer Karel Capek in his play R.U.R.
(Rossm’s Universal Robots), which
premiered in 1921.
 The play begins in a factory that
makes artificial people called robots

5.  The first digitally operated and
programmable robot, the
Unimate, was installed in 1961 to
lift hot pieces of metal from a die
casting machine and stack them.
 Fully autonomous robots only
appeared in the second half of
the 20th century.

6.  As the name suggests a robot must have a
system to make it move.
 This system gives our machine the ability to
move forward, backward and take turns.
 It may also provide for climbing up and
down.

7.  The concept of locomotion invariably needs
rotational motion e.g. a wheel driven by
some power source.
 This involves conversion of electrical energy
into mechanical energy, which we can easily
achieve using electrical motors.
 The issue is to control these motors to give
the required speed and torque.

8.  Suitable power source is needed to run the robots.
 Mobile robots are most suitably powered by batteries.
 The weight and energy capacity of the batteries may
become the determinative factor of its performance.

9.  They convert the electrical energy into
meaningful mechanical work.
 Mechanical output can be rotational or linear
(straight line).
 Motors provide rotational motion.
 Electromagnets provide linear motion

10.  Controlling the current by passing it through
a variable resistor is not advisable as it is
extremely energy inefficient.
 A trick is done to achieve reduced average
power.
 Power is supplied to the motor in short
intermittent bursts, as explained further

11.  Nowadays, robots do a lot of different tasks in many
fields and the number of jobs entrusted to robots is
growing steadily. That's why in my opinion one of the
best ways how to divide robots into types is a division
by their application.
 There are :-
-- industrial robot
-- medical robot
-- military robot
-- service robot
-- space robot

12.  Industrial robots - Industrial robots
are robots used in an industrial
manufacturing environment.
Usually these are articulated
arms specifically developed for
such applications as welding,
material handling, painting and
others. If we judge purely by
application this type could also
include some automated guided
vehicles and other robots

13.  Medical robots - Robots used in medicine and
medical institutions. First and foremost -
surgery robots. Also, some automated
guided vehicles and maybe lifting aides.
 There seems to be high risk of difficulties in
most of the surgeries and some times there
are chances for mortality. Hence, most of
the scientists and doctors made various
researches in order to make the surgeries
safe and secure. In such situations, robots
can help a lot in making the surgery more
safer since they could make smaller cuts in
the organs or tissues. This would in turn
make the patients feel easier and
comfortable.

14.  Military robots - Robots
used in military. This
type of robots includes
bomb disposal robots,
different transportation
robots, reconnaissance
drones. Often robots
initially created for
military purposes can be
used in law
enforcement, search
and rescue and other
related fields

15.  Entertainment robots - These
are robots used for
entertainment. This is a
very broad category. It
starts with toy robots
such as robosapien or
the running alarm clock
and ends with real
heavyweights such as
articulated robot arms
used as motion
simulators

16.  Space robots - I’d like to single
out robots used in space as
a separate type. This type
would include robots used
on the International Space
Station, Canadarm that was
used in Shuttles, as well as
Mars rovers and other
robots used in space

17.  Today we find most robots working for
people in industries, factories,
warehouses, and laboratories. Robots
are useful in many ways. For instance,
it boosts economy because businesses
need to be efficient to keep up with the
industry competition. Therefore, having
robots helps business owners to be
competitive, because robots can do
jobs better and faster than humans can,
e.g. robot can built, assemble a car. Yet
robots cannot perform every job; today
robots roles include assisting research
and industry. Finally, as the technology
improves, there will be new ways to use
robots which will bring new hopes and
new potentials
