There are roughly two main categories of uses of
robotics based on the types of jobs robots have to
There are jobs that a robot can do better than a human, in
which they increase productivity, accuracy, and
There are also jobs that a human can do better than a
robot, but humans are removed from the activities
because they are dirty, dangerous, and dull tasks.
There are also unusual robots, which let us investigate
new types of robots. These new types of robots will be
able to solve real world problems when they are
Jobs that require speed, accuracy, reliability
or endurance can be performed a lot better
by robots than humans.
Robots have replaced humans in factories for over
fifty years now.
We’re allowed to have cheaper mass
including many automobiles, appliances, and
The amount of installed robots has grown to more than
800,000 worldwide (42 % in Japan, 40% in the European
Union and 18% in the USA).
Factory work suits robots because it can be
accurately defined and repeated in the same
manner every time, requiring no intelligence or
feedback from the robot. The robots may
require some basic exteroceptors to sense things
in their environment.
Automated Guided Vehicles
This is the number one example
of factory automation.
Factories have been dominated
by robots for the past three

There are many jobs that a human could do a lot
better than any single robot, but usually the human
does not want to do this particular job or cannot be
present to carry out the particular task needed to be
accomplished so he has robots carry out the task for
These types of jobs may be too boring to carry out, such as
house hold cleaning
Other jobs may be too dangerous to carry out, such as the
exploration from within a volcano.
Or jobs may be inaccessible, such as exploration of an
unknown planet, cleansing of a long pipe or the
performance of laparoscopic surgery.

Prices of these robots keep
on dropping and their

Currently more of these robots
have been sold than any other
single type of robot because
they seem to be relatively
autonomous, usually requiring
a command to begin their job.
Robots take on unwanted
tasks such as :
Telerobots are used when a
human cannot be present on
site to perform a specific task
because it is too dangerous, far
away, or inaccessible.
Usually the robot will be in
another room or country,
depending on where the robot
has to accomplish a task, away
from the operator.

Marine remotely operated
vehicles are used to work in
water that is too deep or too
dangerous for divers to explore.
These vehicles repair offshore
oil platforms and attach cables
to sunken ships to hoist them.

named Titanic was actually

This is the use of robotic technology to help
orthopedic surgeons in the healing, repair, and
replacement of any joint related conditions.
It is a minimally invasive method for viewing forms within
the body and performing surgery on a joint.
Arthrobotics uses a fiber
optic instrument, which is
inserted through a tiny incision that enables remote
viewing of the joint through an eyepiece or on a
Future arthrobotic uses will potentially incorporate
complete joint replacement with bionic bionics and
computer interfaces for limb control from
neural impulses in the brain.
Teleoperated robot aircraft, like the

army to search terrain, fire at targets

MIDARS is a four
wheeled robot outfitted with several cameras, a
radar, and possibly a firearm, that automatically performs random

It alerts a human when it detects movement in an unauthorized area,
or other programmed conditions.
The robot would also frequently scan radio frequency identification
tags placed on stored inventory. It would be able to record any items
that were missing.
U.S. scientists at MIT are looking into building a mechanical super
fighter who would be able to heal his own wounds, leap buildings,
deflect bullets and even become invisible. The invisibility part of
the robot wouldn’t be ready for at least another 10 years.

unavailable due to the increasing
amount of elder people and not

Japanese nursing homes have
robots installed within them to help
care for elderly people.
A package of sensors is placed inside
a teddy bear. The bear speaks to the
elderly individual and asks him or her

Researchers also hope to create robots as small as viruses or bacteria,
allowing them to carry out tasks on a small scale.
Some applications of these robots would include: micro surgery,
utility fog, manufacturing, weaponry and cleaning.
Medical technology might be used to identify cancer cells and destroy them.
Another potential application is the detection of toxic chemicals, and the
measurement of their concentrations, in the environment.
Rice University has recently demonstrated a single

environmental temperature and by positioning a scanning tunneling
Nanotechnology coatings are being used to make clothing with stain

friction with the water, and allow swimmers to go faster.

Specialized robots such as the
haptic interfaces are used
Haptic technology refers to
technology which interfaces the user
via the sense of touch by applying
forces, vibrations and/or motions to
the user. This type of virtual reality is
used in various video games.
Haptic interfaces allow touch
enabled user interaction with real
and virtual environments.
Robotic forces allow simulating the
mechanical properties of virtual
objects, which users can experience
through their sense of touch.
