As the world is advancing day by day, and we are becoming more and more technology-dependent, almost everything has become remote-controlled. From our home appliances to our vehicles, everything has become technologically advanced, and we can have anything ordered at one click. Similarly, spying, military, and other fields are trying their best to use top-notch technology to fight against the enemy.

The Wright Brother’s flying venture was seen with skepticism, now we are able to enhance information gathering using drone technology. With this past decades technological advancement, most people want to know more about a drone. What is a drone? How does it work? What are they used for? All these questions arise when we think about this small but a genius invention. We are going to answer all of these questions in the article below.

Drones also known as an ‘unmanned aerial vehicles’ (UAV) or un-crewed aerial vehicles, are an advanced form of quadcopter aircrafts which work without a human pilot on board. UVAs stem from unmanned aircraft system (UAS) which includes two main components; a ground-based controller, and the other is the UAV which includes a system of communications between the two. Different methods are used to operate the UAV including a remote control, autonomous operation or even onboard computers.

A drone can be defined as an “unmanned aerial vehicle (UAV) which can either be operated by a human from any remote location or you can make it work autonomously as per already set mode.”

A funner definition is that a drone can be considered as a robot that flies. Unlike aircraft, it does not have a dedicated remote unit. However, it does have many onboard working sensors like GPS, which are helpful in flight mode controls.

Origins of Drones

The history of drones goes back to as long as the military usage of technology can be traced. The primary purpose of the drones was to provide information to the military, prior to commercial use. Initial attempts can be traced back to as far as the 1930s, when the first aircraft with reusable type radio control mechanism was designed. It was the first model, and all the next models are based on that specific one. Other military drones were then established with sensors and camera units.

Moreover, the technology has so much advanced that now these drones can be fit into missiles too. Everyday more and more innovation is being brought in to this technology. Now the role of drones is not just restricted to military usage. However, many big companies are also working on these. For example, big item delivery companies are trying to develop their drones so their parcels can be delivered with ease. Another innovative idea is given by a social media giant to create a drone that can carry the internet signals to remote locations for direct and fast internet connections. Other primary usages includes media publishing. Here drones are not only used for information-carrying but also recording from remote and inaccessible locations.

How Does Drones Work?

RC Drones are also known as quadcopters, which tell us about its working using four different rotors. It should be interesting to know that drones are considered successors of helicopters. The succession can be found as they work on almost the same mechanism. However, a helicopter is a human-crewed vehicle. Yet, a drone can fly independently and does not need a pilot for directions. It may sound simple, but drones carry a very complex technology within them which predates to helicopters. To understand the working of drones, one must make oneself familiar with the helicopter technology that works on the propeller system.

Technology Used in Drones

A typical uncrewed aerial vehicle is made of light composite materials, so the weight is minimized, and maneuverability is increased. That is why these drones can go up to too high altitudes. The leading technologies used in these UAVs are as follows.

  • GPS
  • Infrared Camera
  • Laser (military UAV, commercial, consumer)
  • Ground Control System (GSC) for controlling the drone (it is also known as ground cockpit)

All the UAVs have a two-part system, one of them is the drone itself, and the other is the control system. All the sensors are located at the nose of the UAV. The other body has other technology systems because you don’t space to accommodate any pilot or operator. The material used in building a drone is highly complex composites designed so the vibration can be absorbed to make the sound lowered and to make it lightweight.

A specially designed multi propeller system is used inside a drone, which makes the device-independent and it helps to ground. The other important thing to know is the fact that with its multi propeller system, even if one of them stops working, it will continue flying because of support from other propellers. All of these propellers are working in a group, and one supports the other if there is a problem in one propeller. Drones with more motors inside them have more control over their elevation, and they can carry more loads. All of the propellers have their reliable source, and most of these devices have removable batteries so they can stay up for a more extended period. Powerful batteries can also be used to increase the flight time.

Flight of a Drone

The flying mechanism of a drone is part of it’s definition. To control the RC drone, a controller is placed in the hand of a person who wishes to fly and guide the drone. An expert uses this device to control every movement of a drone. This controller contains all the activities from launch to land and navigation. There are a lot of different types of controllers, and developers love to use innovation, and drones with many impressive features are out there. A controller plays a significant role in the proper communication channel between radio waves and the remote unit.

Most of the drones work on 2.4 GHz frequency range, and help is also taken from Wi-Fi networks so operational decisions can be made regarding movements. The drone’s functions also take inspiration from smartphones as it has many functions like GPS, Wi-Fi, and other standard sensor units. These onboard sensors make the decisions by drones about staying in the air for long run or height, direction, or basic movements. When the drone is landing, these sensors also decide motor rotation, speed, and altitude, etc. A drone is an intelligent air unit as it can cover a larger distance if powerful batteries are used. You can get all the information you want, and that is the main reason for its usage in military operations.

What are Drones used for?

Drones were first developed for military purposes, which is still one of the essential uses of drones. After a few years, different and innovative ideas for the benefit of drones are coming out, and people were thinking of more productive uses of drones. With the passage of time and advancement in technology, drones are now used for many other purposes. Now a drone can be seen photographing and delivering stuff and whatnot. Some of the most commonly seen functions of a drone are given below.


Drones are used heavily for military purposes. It has been documented that The British and U.S. militaries used their first drones in the 1940s to spy on the Axis Powers. Now they are more advanced with a lot of latest technology, and it can now spy a lot better along with missiles attached to them.


This one is my personal favorite because now drones are being used for capturing photographs and video recording. You want a birds-eye view of your building, city, or a place, and you can have it using your drone. Drones are now available, which are specially developed for a photograph.

Medical Usage

When people in remote areas require medical supplies, there are not always people available to provide resources to those areas. That’s where our drones come in. Other things, like delivering organs for transplant patients, can also be done by using drones.

Delivery of Goods

Another new and somewhat less common use of drones is the delivery of goods. Any autonomous UAV can be used for package transfer, food transport, and goods transport.

Emergency Rescue

When it’s not safe to send human help for rescue, that’s where the drones come in to save the day during a disaster or an emergency.

These are only a few uses of drones, and now many innovative ideas are coming through, which are only making drones more useful.
