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:

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.
