In the modern world, we are too dependent when it comes to technology .There is no denying that we simply can’t live without it now. Smart phones are always in our hands with speedy access to the internet on- the- go to the extent of instantly getting in touch with almost anyone across the world. We shop online, order food online and make bill payments online, to name a few.
Drones (Unmanned Aerial Vehicles) are new emerging equipment in science and technology which play a major role in addressing so many problems in Society and they are surely going to standardize our living.
Although the word ‘Drones’ come from the military background, but today it is offering numerous exciting opportunities with equal number of challenges. Just like any other aircraft, drones must be flown in safe way.
Drones overall will be more impactful than I think people recognize, in positive ways to help society.
– Bill Gates
DRONE word stands for Dynamic Remotely Operated Navigation Equipment. Drones are more formally known as unmanned aircraft systems (UASes) or unmanned aerial vehicles (UAVs). A drone, in technical terms, is an unmanned aircraft without onboard pilots.
A drone is a flying robot that can be operated remotely by either a human or by a computer. Drones are equipped with state of the art technology such as onboard GPS, infrared Sensors, and Lasers and embedded system for controlling purpose and flight plans. The unmanned vehicle consists of mainly two parts, the drone itself and control system.
Drones come in different size, configuration, shape and characteristics.
Drone System Parts
The first drones use in history was on August 22, 1849 when Austria launched 200 pilotless balloon bombs against Venice. This was followed by Japan’s World War 2 balloon attacks on North America. The birth of modern drones began with US Air Force in 1959 and used in 1960 under the code name Red Wagon against Soviet Union shoot down.
After 1980s, Drones were successfully developed to use in military and currently they are becoming increasingly popular in commercial and private market for various uses.
The need for Drones became apparent when US army took serious note on its army pilot’s losses during aerial attacks in hostile territory. Drones are used in situations where manned flight is considered too risky, too expensive or too difficult.
So many inventions happened in 21st century like smart phones, social networking, GPS, Artificial Intelligence, IOT, Robotics so on etc but problems still persist in the world in fields like Agriculture, Healthcare, Transportation and Wars. Satellites provide aerial view but they cannot go physically to assist on field problems. But drones play a major role to minimize the amount of burden these sectors are facing and they are surely going to standardize our living.
Multi Rotor Drones: These are made with central body and multiple rotors usually four, but can have six to eight rotors that power propellers to take flight up. They can be lifted up vertically and easy to use. Stability in air is the drawback for this. These are used in Aerial Photography and Video Aerial Inspection.
Fixed Wing Drones: These are designed more like traditional airplanes which have a central body and two wings and a single propeller. They cannot be lifted up vertically and need space for launching. They can cover large area with high speed and are stable in the air. These are used in Aerial Mapping, Pipeline and Power Line Inspection.
Single Rotor Drones: These are designed similarly like a helicopter with one big rotor plus a small sized rotor on the tail for direction and stability. They can be lifted up vertically, are strong and durable and have long lasting flight time. They are expensive and complex. These are used in Research, Aerial LIDAR laser scan, Surveying.
Fixed Wing Hybrid VTOL: Still in development.

Drones are used in variety of areas from agriculture to vacuuming up ocean waste to delivering pizza, and more. Below are some of the main uses of drones across industries.
Some of Indian Military Drones: DRDO AURA, Lakshya PTA, Pawan UAV, Gagan UAV
Drones in Healthcare
Drones in Agriculture
Drones for Disaster Control
Drones in Wildlife Conservation
Drones are of great use for society in all aspects when used properly. But if we don’t give much attention are if we use them for illegal activities drones only can turn into drawback for people. Some of the disadvantages drones are below.
Although drones are criticized more for violating human privacy and irresponsibility by hobbyists, new uses of drones are promising to greatly benefit the society. Today, In society Drones are used to capturing new videos, recording vacation travel logs, filming movies, surveying , delivering packages , military purposes , agriculture , predictions on weather and so many that drones are really needed for the society for fast pace growth.
