2. What do we mean by Robotics?
Robotics is an interdisciplinary field that integrates
computer science and engineering. Robotics involves
the design, construction, operation, and use of robots.
The goal of robotics is to design machines that can
help and assist humans.
Why is Robotics important?
Robotics technology influences every aspect of work
and home. Robotics has the potential to positively
transform lives and work practices, raise efficiency and
safety levels and provide enhanced levels of service.

3. Application Of Robots
Robots can be used in many situations and for many purposes,
but today many are used in dangerous environments (including
inspection of radioactive materials, bomb detection, and
deactivation), manufacturing processes, or where humans cannot
survive (e.g. in space, underwater, in high heat, and clean up and
containment of hazardous materials and radiation).
Robotic aspects
There are many types of robots; they are used in many
different environments and for many different uses.
Although being very diverse in application and form, they
all share three basic similarities when it comes to their
construction.

4. History Of Robotics
In 1948, Norbert Wiener formulated the principles of cybernetics, the
basis of practical robotics. Fully autonomous robots only appeared in
the second half of the 20th century. 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.
Commercial and industrial robots are widespread today and used to
perform jobs more cheaply, more accurately, and more reliably than
humans. They are also employed in some jobs which are too dirty,
dangerous, or dull to be suitable for humans. Robots are widely used
in manufacturing, assembly, packing and packaging, mining,
transport, earth and space exploration, surgery, weaponry, laboratory
research, safety, and the mass production of consumer and industrial
goods.

5. Types of Robots
Mechanical bots come in all shapes and sizes to
efficiently carry out the task for which they are
designed. From the 0.2 millimeter-long “RoboBee” to
the 200 meter-long robotic shipping vessel “Vindskip,”
robots are emerging to carry out tasks that humans
simply can’t. Generally, there are five types of robots:
Pre-Programmed Robots
Pre-programmed robots operate in a controlled environment
where they do simple, monotonous tasks. An example of a pre-
programmed robot would be a mechanical arm on an automotive
assembly line. The arm serves one function — to weld a door on, to
insert a certain part into the engine, etc. — and its job is to perform
that task longer, faster, and more efficiently than a human.

6. Humanoid Robots
Humanoid robots are robots that look like and/or mimic human
behavior. These robots usually perform human-like activities (like
running, jumping and carrying objects), and are sometimes designed
to look like us, even having human faces and expressions. Two of the
most prominent examples of humanoid robots are Hanson Robotics’
Sophia (in the video above) and Boston Dynamics’ Atlas.
Autonomous Robots
Autonomous robots operate independently of human operators.
These robots are usually designed to carry out tasks in open
environments that do not require human supervision. An example
of an autonomous robot would be the Roomba vacuum cleaner,
which uses sensors to roam throughout a home freely.

7. Teleoperated Robots
Teleoperated robots are mechanical bots controlled by humans.
These robots usually work in extreme geographical conditions,
weather, circumstances, etc. Examples of teleoperated robots
are the human-controlled submarines used to fix underwater
pipe leaks during the BP oil spill or drones used to detect
landmines on a battlefield.
Augmenting Robots
Augmenting robots either enhance current human
capabilities or replace the capabilities a human may have
lost. Some examples of augmenting robots are robotic
prosthetic limbs or exoskeletons used to lift hefty weights.

8. Components Of a Robots
Power Supply
Actuators
Electric motors (DC/AC)
Sensors
Controller

9. Power Supply
The working power to the robot is provided by batteries,
hydraulic, solar power, or pneumatic power sources.
Actuators
Actuators are the energy conversion device used
inside a robot. The major function of actuators is to
convert energy into movement.

10. Sensors
Controller
Sensors provide real time information on the task environment.
Robots are equipped with tactile sensor it imitates the mechanical
properties of touch receptors of human fingerprints and a vision
sensor is used for computing the depth in the environment.
Controller is a part of robot that coordinates all motion of the
mechanical system. It also receives an input from immediate
environment through various sensors. The heart of robot's
controller is a microprocessor linked with the input/output and
monitoring device. The command issued by the controller
activates the motion control mechanism, consisting of various
controller, actuators and amplifier.
