If you are interested in knowing more about this field of study, this blog explores robotics basics, types, importance, applications, and future scope.
What is Robotics?
Robotics is a multidisciplinary field that focuses on designing, building, operating, and using robots. A robot is a mechanical or virtual machine that is programmable and can autonomously (or with human assistance) execute tasks. These activities may be simple, such as lifting things, or challenging, such as conducting surgeries or space exploration.
History of Robotics
The history of Robotics spans centuries. It evolved from early mechanical inventions to today’s advanced robotics machines available in the market. The table below discusses the series of events that have shaped the world of Robotics that we know today.

Robotics Basics
Although robots perform different functions, the common denominator is that most systems have the following key elements:
Control System
The control system is the brain of the robot. It relies on software, algorithms, or programmable logic controllers (PLCs) to determine how a robot responds to the inputs. They are used to make sure that the robot functions effectively and safely.
Motors
Electrical energy is transformed into mechanical motion by motors. They facilitate the movement of various sections of the robot, including wheels, arms or joints. Common types include DC motors, servo motors and stepper motors.
Actuators
Actuators convert energy into physical motion. They enable robots to move, pick, or perform any action on a given object. Actuators collaborate with sensors to enable the robot to react favourably to its surroundings.
End Effectors
End effectors are instruments fitted on the arm of a robot that are used to interact with objects. They function like a robot’s “hands” and perform tasks such as gripping, cutting, welding, or assembling. They can be customised based on the task.
Power Supply
The power supply provides the energy required for the robot to operate. It may be provided through batteries, electrical or renewable energy. This is required to have reliable power in order to operate smoothly and continuously.
Communication System
This system enables the various components of the robot to communicate with each other, as well as to communicate with other systems or users. It can be wired or wireless and ensures smooth data transfer for proper functioning.
Program
The program is the set of instructions that controls the robot’s actions. It is written in a language such as Python or C++, and it defines how the robot operates, moves, makes decisions, and communicates with the environment.
Types of Robots
Robots come in all shapes and sizes. They are used in various industries such as education, healthcare, manufacturing, and entertainment, etc. The popular types of Robotics are as follows:
