What is Robot?
• Powered by Electricity.
• Programmed to carry out certain tasks, like
cleaning, etc.
• Senses the environment using sensors and
reacts accordingly on its own.

THE ‘SKELETON’
• What is a body without a skeleton? Nothing
but a soft sac, without the rigidity, and the
shape that defines it.
• Here, the only difference between the robot
and us is that it is not exactly a spongy sac; it
is a hard sac, with a lot of dismantled parts.
• Our skeleton has bones, a robot’s skeleton is
a robot chassis or simply a chassis – it is a
frame (in our case a base plate) onto which
everything - the actuators, the effectors, the
wheels, the castor, the grippers, the brain - is
attached and supported.

THE ‘SENSES’
• A sensor is a device that detects input from
the outside world and responds to it.
• Just like we have many different types of
senses and different ‘sensors’ for them, such
as eyes for seeing, ears for hearing, nose for
smelling, tongue for tasting, and skin for
touching, robots are also capable of sensing
different things such as light, sound, and
temperature, and have many different
sensors for them.

THE ‘e-BRAIN’
• The robot has detected all that is happening
around it. Now, it has to respond to it. But it
needs to make sure that it does to correctly.
Who or what is going to tell him what to do,
and how to respond in the right way?
• The brain is responsible for controlling all
the senses, and, functions of the body,
such as thinking (I think, therefore I am),
eating, sleeping, and moving the arms and
the legs.
• The robot’s brain also does the same. It
controls what it thinks, what it does, and
how it moves its arms and legs.

THE ‘e-BRAIN’
• At this moment, our robot’s got everything;
right from the brain down to the feet. But
since it is not exactly a human, it still doesn’t
know as of yet what to do and how to do it.
• You will give commands to the robot and ask
it to do what you want him to, and he has to
follow them!
• These commands that we are talking about
are nothing but the instructions that are
given by writing a program for the specified
task.
