How Does Drone Technology Work?

The term “drone” refers to an aircraft without a pilot. That’s why, it goes by the name of ‘remotely piloted craft’ (RPA), which doesn’t have any onboard pilot, or as, “remotely piloted systems” (RPAs). In simple words, it’s an “Unmanned Aerial Vehicle” (UAV), without any human crew, pilot, or passengers on board. Some drones are controlled with an application on a tablet, computer, or smartphone, while others are controlled with the help of a remote controller. This article will help you learn about the intricacies of drone technology, how a drone works, and our top three best drones, with detailed insight into their important features.

How Does Drone Technology Work?

With a GPS and a joystick, operating the most common consumer drones might not be more complex than playing your favorite video game. However, underneath the easy-looking user interface lie a gyroscope, an accelerator, and many other complex technologies working to make a drone flight as smooth as possible.

The technological advancements in the field of drones have been advancing ever since. Each day, there’s new drone technology, making life easier and smarter for individuals and organizations. Let’s have a look into the basic technological factors of a drone, and how they work.

1. Connectivity

Let’s start with one of the most basic controls of drones, connectivity. As discussed above, drones are remotely controlled from a tablet or a mobile phone. The pilot can view the surroundings of a drone, from a birds’ eye perspective, with wireless connectivity. As a remote pilot, you can also make use of some apps, to pre-program some specific GPS coordinates, and make an automated path for your drone flight. Another benefit of using wireless connectivity is that you can track the battery charge in real-time. This is an important factor, keeping in mind that most drones use smaller batteries to lower their weight.

2. Rotors for Vertical Motion

A drone mainly relies on rotors for its vertical motion. A rotor consists of a propeller that is attached to a motor, which makes the drone hover. This means that the downward thrust of the drone is the same as the gravitational pull working against it. To make the drone climb, the pilot increases the speed, to the point where the rotors manage to produce an upward force greater than gravity. Finally, for a drone to descend, the pilot would perform the opposite and decrease the speed.

A drone consists of four rotors. For a drone to hover, two of its rotors move clockwise, while the other two move anticlockwise. This movement ensures that the sideways momentum of the drone is balanced. To avoid the drone from going into an unexpected/irregular path of a vertical motion, the other two rotors increase the spin. The same rule applies to the forward and backward motion – the rotors of the drone should apply thrust, and their spin must balance out the drone.

3. Accelerometer and Altimeter – for Direction and Altitude

An accelerometer provides the drone with information about its direction and speed, while an altimeter feeds the UAV an input of its altitude. These features significantly help the drone land slowly and safely. Resultantly, they also help prevent the drone from sinking into an air vacuum, known as a wash that can pull the machine down in an unpredictable manner.

4. Cameras

Some drones come with built-in cameras that allow you (as a remote pilot), to track the flight path of the drone, without having a direct line of sight to the machine. The drone-mounted cameras are massively used by the content creators or filmmakers to reach high and difficult locations. These types of drones can also be a game-changer for first responders, specifically in search and rescue situations.
