As you all know, a robot is a programmable machine capable of performing tasks and interacting
            with its surroundings. Robotics is the science and technology behind designing, manufacturing, and
            applying robots. Robots cannot do anything by themselves. Different parts of Robots are meant to
            perform different tasks.
            First, let us understand the difference between humans and robots.


            Difference Between Humans and Robots

            The following table shows some of the common differences between humans and robots:

              S. No.    Humans                                        Robots

              1.        Humans are organic entities.                  Robots are mechanical devices.
              2.        Humans can die; they never come back          Robots cannot die; they can be repaired.
                        to life.
              3.        Humans have a highly developed brain.         Robots have a trained brain.

              4.        Humans are social beings.                     Robots do not socialise.

              5.        Humans are capable of performing              Robots can handle only specialised tasks.
                        creative and innovative tasks.
              6.        Humans have emotions and feelings.            Robots do not have emotions and feelings.


            Essential Parts of Robots

            Humans  have  set  body  parts,  whereas  robots  have  body  parts  according  to  their  needs.  This  is
            the reason robots come in different sizes and shapes. Industrial robots look very different from
            Astronaut robots.
            Let us study about some of the essential parts of Robots.

            Manipulator

            The  robot’s  Manipulator  is  just  like  a  human  arm  and  has  several  joints  and  links.  They  are
            electronically controlled devices consisting of multiple sections. A manipulator uses strong links
            connected by joints with one fixed end and one free end to perform a given job, such as moving a
            box from one location to another.
