The document provides information about robots, including definitions, history, and key aspects. It defines a robot as a re-programmable, multifunctional manipulator designed to move materials through programmed motions. The term originated from a 1921 play and was later used by Isaac Asimov in 1941 to refer to machines that assist humans. Key robot aspects discussed include motors, sensors, mobility, programmability, and flexibility. Examples of present and future robots are also mentioned.
2. What is a Robot ?
“A re-programmable,
multifunctional manipulator
designed to move
material, parts, tools, or
specialized devices through
various programmed
motions for the performance of a
variety of tasks.”
3. History
The term robot originates from the Czech word robota,
meaning “compulsory labor.” It was first used in the
1921 play R.U.R. (Rossum's Universal Robots) by the
Czech novelist and playwright Karel Capek. The word
robot has been used since to refer to a machine that
performs work to assist people or work that humans
find difficult or undesirable.”
In 1956, George Devil and Joseph Engelberger
formed the world's first robot company, but writers
have been dreaming about robots long before that.

automata, including a fire engine, a wind organ,
a coin-operated machine, and a steam-

others
1st real known example was in 1206. First

5. According to the Oxford English Dictionary, the word
robotics was first used in print by Isaac Asimov, in his
science fiction short story "Liar!", published in May
1941 in Astounding Science Fiction. Asimov was
unaware that he was coining the term; since the
science and technology of electrical devices is
electronics, he assumed robotics already referred to
the science and technology of robots. However, in
some of Asimov's other works, he states that the first
use of the word robotics was in his short story
Runaround
6. Isaac Asimov's Three Laws of Robotics
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 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.

11. Mobility: It possesses some form of mobility.
Programmability: implying computational or symbol-
manipulative capabilities that a designer can combine
as desired (a robot is a computer). It can be
programmed to accomplish a large variety of tasks.
After being programmed, it operates automatically.
Sensors: on or around the device that are able to
sense the environment and give useful feedback to
the device
12. Mechanical capability: enabling it to act on its
environment rather than merely function as a data
processing or computational device (a robot is a
machine); and
Flexibility: it can operate using a range of programs
and manipulates and transport materials in a variety of
ways.
13. Motors: The vast majority of robots use electric
motors, including brushed and brushless DC motors.
Stepper motors: As the name suggests,
stepper motors do not spin freely like DC motors;
they rotate in discrete steps, under the command of
a controller. This makes them easier to control, as
the controller knows exactly how far they should
have rotated, without having to use a sensor. The
controller can't tell if the motor has stalled and the
shaft didn't turn. They are used on many robots and
CNC machines, as their main advantage over DC
motors, is that you can specify how much to turn, for
more precise control, rather than a "spin and see
where it went" approach.
14. Piezo motors: A recent alternative to DC motors are
piezo motors or ultrasonic motors.
Air muscles: The air muscle is a simple yet powerful
device for providing a pulling force. When inflated
with compressed air, it contracts by up to 40% of its
original length. The key to its behavior is the braiding
visible around the outside, which forces the muscle
to be either long and thin, or short and fat (almost
like a Chinese finger trap). Since it behaves in a very
similar way to a biological muscle, it can be used to
construct robots with a similar muscle/skeleton
system to an animal. For example, the Shadow robot
hand uses 40 air muscles to power its 24 joints.
15. Sensors
Sensors are the parts that act like senses
and can detect objects or things like heat
and light and convert the object
information into symbols or in analog or
digital form so that computers
understand. And then Robots react
according to information provided by the
sensory system
Vision Sensor
Proximity Sensors
Proprioceptive Sensors
Logical Sensors
16. POWER SOURCE
At present; mostly (lead-acid) batteries are used, but
potential power sources could be:
pneumatic (compressed gases)
hydraulics (compressed liquids)
organic garbages (through anaerobic digestion)
feces (human, animal); may be interesting in a
military context as feces of small combat groups may
be reused for the energy requirements of the robot
assistant (see DEKA's project Slingshot stirling
engine on how the system would operate)
17. Touch
Current robotic and prosthetic hands receive far less
tactile information than the human hand. Recent
research has developed a tactile sensor array that
mimics the mechanical properties and touch receptors
of human finger tips. The sensor array is constructed
as a rigid core surrounded by conductive fluid
contained by an elastomeric skin. Electrodes are
mounted on the surface of the rigid core and are
connected to an impedance-measuring device within
the core. When the artificial skin touches an object the
fluid path around the electrodes is deformed,
producing impedance changes that map the forces
received from the object.

It is the science and engineering of

27. Present Robots
Wakamaru
The Wakamaru is the first human-
size robot that can provide
companionship, or function as a
caretaker and house sitter. The
Wakamaru was created in Japan,
and will be for sale there for about
one million yen ($14,250). The
Wakamaru moves around on
wheels, is 3.3 feet tall, weighs 60
pounds, and recharges itself when
batteries run low.

42. Robots recently became a popular tool in raising
interests in computing for middle and high school
students. First year computer science courses at
several universities were developed which involves
the programming of a robot instead of the traditional
software engineering based coursework. Examples
include Course 6 at MIT and the
Institute for Personal Robots in Education at the
Georgia Institute of Technology with
Bryn Mawr College.
Some specialised robotics jobs require new skills,
such as those of robot installer and robot integrator.
While universities have long included robotics
research in their curricular offerings and tech schools
have taught industrial robotic arm control,
