If you just purchased your first drone or have been using them for some time however don’t understand how they really work and you’re curious to know more, you’ve come to the right place.
The controllers, joysticks, and apps make flying a drone as simple as enjoying a video game. But throughout the drone, there are small parts that each one work collectively to verify the drone can fly. So, how do drones work?
The most important parts of a drone are the working system and the flight controller. Batteries power the rotors inflicting them to spin the propellers and generate carry. The flight controller uses the data collected by accelerometers, barometers, magnetometers, gyroscopes, and the controller to remain in the air.
Other necessary features that improve the functioning of a drone embrace GPS, obstacle detection and collision avoidance, cameras, and software program.
Please hold studying to find out how all elements of a drone work and how they all contribute to a drone’s flight.
How drones fly (UAV drone propulsion technology)
A lot goes into the drone generating upward carry and performing varied actions. And in this part, we’ll focus on how all that works. But before that, let’s first listing all of the components that play a task within the propulsion of a drone:
* Motor Bell
* Motor Stator
* Flight controller
Also, before we focus on how each of those parts works, let’s outline some widespread drone actions:
* Yaw – This is when the drone’s entrance part rotates in a clockwise or counter-clockwise course.
* Pitch – This is the lean the drone assumes relying on the path it’s transferring. To speed up ahead, drones decrease the front section and carry the rear part. To reverse, they lift the entrance section and decrease the rear part.
* Roll – This is the motion during which a drone strikes to the left or the proper.
I will clarify the function of propellers and motors in every of those actions later within the article.
This is considered one of the most vital parts of the propulsion system. Batteries energy the motors, inflicting them to rotate at high speeds. As a end result, the motors rotate the propellers, creating raise. Quite easy, right? Not really.
There are two major forms of motors; brushless and brushed motors. Brushless motors are essentially the most generally used as a end result of they’re environment friendly, sturdy, and may rotate at very excessive speeds.
So, what’s the distinction between brushed and brushless motors? It all comes all the method down to how they function. But earlier than I explain the differences, let’s define the primary parts that differentiate them.
* Stator – A stator is the part of a motor that has windings. It’s the half that gives a magnetic subject, which then initiates rotation within the rotor. To create a magnetic subject, stators have windings of copper wire which turn into magnets each time a present runs via them. In most circumstances, the stator is stationary.
* Rotor – The rotor is the half that rotates, causing a rotation in the shaft, which then causes a rotation of the propellers.
* Air Gap – This is the distance between the rotor and the stator. The bigger it’s, the less effective the motors might be.
* Motor Bell – This is the half that causes the propellers to rotate both clockwise or counter-clockwise.
Both brushed and brushless motors have a stator and a rotor. But in the brushed motors, the stator continually offers a permanent magnetic field. Stators encompass a rotor, which may have opposite polarity, and a rotation within the rotor will occur when the commutator brushes interact with a power provide.
The contact of these brushes with the power supply makes brushed motors ineffective since they put on out faster, and the warmth produced hastens the carrying of the drone.
On the opposite hand, brushless motors lack brushes. Instead, the stator goes on and off, providing a magnetic area when necessary. Attraction and repelling between the stator and rotor are what trigger the rotation. And since there’s no contact, like with the brushes within the brushed motors, there’s no heat generation, and there’s minimal wearing out.
Drone motor bearings
Bearings are often missed, and you might not know they exist unless you verify the motors. Still, they’re very useful in minimizing the air gap talked about earlier and preserving the rotors in place as they rotate.
As a matter of truth, if your motors fail, chances are bearings are the problem. When it comes to bearings, there are shielded and unshielded bearings. Shielded bearings work best for drone motors since the motors rotate at high speeds, generating very excessive temperatures that could destroy the bearings.
The propellers should rotate in several directions to generate carry and maintain the drone within the air. In each pair of propellers, one is rotating clockwise (CW), and the opposite one is rotating counter-clockwise (CCW).
As they rotate, they create a zone of low strain. Air strikes from low-pressure regions to high-pressure regions. That’s how the drone is ready to move up, down, forward, or backward relying on how the speeds at which the propellers rotate.
Also, the quantity of thrust generated needs to balance out the drone’s weight, causing it to be dislodged into the air.
Number of propellers
Most drones have four propellers, and are generally known as quadcopters. This didn’t happen by likelihood or as a approach to give the drones their signature look. There’s a reason behind it. To clarify it better, let’s begin by assuming a drone had one propeller.
Such a drone would generate enough lift to propel the drone into the air, but will probably be very troublesome to control the drone because it has no method to transfer ahead or in reverse. Besides, the drone will continuously be rotating in the wrong way. This is actually based on Newton’s 3rd Law of Motion; when two objects interact and are in movement, they’ll affect each other in reverse directions.
Having a drone with two propellers would even be an possibility. And as a matter of fact, it will assist save on battery energy. Besides, when you get the propellers rotating in different directions, you cancel the torque exhibited by the single-rotor drone. However, it’s still troublesome to regulate such a drone since it’s not steady.
Unlike the 2-propeller drone, a 3-propeller drone isn’t an possibility since it undoes everything that the 2-propeller drone solves.
And this leaves us with solely four propellers or more. Quadcopters have the proper steadiness to allow the drones to hover, velocity ahead, and make maneuvers with out crashing. What occurs is that each one the motors cancel each other out, sustaining stability and stopping undesirable rotation.
More propellers create more stability, but also create extra draw on the battery. Therefore 4 propellers is the ideal quantity.
To hover, all motors receive equal power and rotate at the similar speed.
To move ahead, the entrance propellers decelerate, whereas the rear propellers increase their pace. This makes the drone pitch ahead by decreasing the entrance part.
To yaw, motors in a diagonal sample will decelerate, allowing the drone to rotate on an axis to the left or the best.
To roll, the rotors on the left or the best are slowed down depending on the path you want to roll in.
How flight controllers work (Transmitter, Receiver, and Smartphone Apps)
Now, all of the maneuvers defined above are constructed into the drone, but there’s one other piece of the puzzle; the flight controllers. Can you think about having to manually control the speeds of assorted rotors simply to show the drone proper or left?
And that’s why drones need a flight controller, a tool that collects knowledge from the various sensors and uses this data to regulate the drone’s motion. The flight controller is a mixture of hardware and firmware that incorporates algorithms that enable it to make sense of all the data it receives from the sensors and the controllers.
Through a process referred to as sensor fusion, the flight controller collects all the data and uses it to make choices in real-time. A good example of algorithms is the Kalman Filter that permits the controller to use previous and current information to make accurate choices.
How it all works
As mentioned earlier, drones speed, turn, slow drown, or roll by altering the speed of the motors. So, as soon as the flight controller collects knowledge from sensors, it sends it to the Electronic Speed Controller (ESC), which then interprets it by growing or decreasing the voltage depending on the motion you want to take.
For instance, if you would like to accelerate ahead, the ESC will cut back the voltage of the entrance rotors to slow them down and enhance the voltage of the rear propellers.
The flight controller additionally receives information from the remote controllers. All you should do is push the joysticks up, down, left, or proper, and the distant controller will send these instructions by way of a radio sign to the drone. On the opposite finish, the drone has a receiver that receives these alerts, interprets them, and effects the command on the drone.
If your drone is controlled via a smartphone, the drone and the gadget typically communicate through Wi-Fi. Most drones have their very own drone apps, which, whenever you set up them on your smartphone, let you easily management the drone with or without the remote controller. But the range may be restricted in comparability with utilizing the controller.
Speaking of range (the furthest distance a drone can travel from a controller), it could range from a few toes to a quantity of miles depending on the drone you’re using and the power of the connection. For toy drones, it’s usually a number of toes, however for shopper and prosumer drones like DJI drones, it can be so far as 5 miles.
> To learn more in regards to the range of frequent drone models, take a glance at our article about how far a drone can fly from the controller »
DJI has made a reputation for themselves in the client drone world by building OcuSync, a sophisticated communication system that enables them to have a protracted operating vary.
For some drones, you could also purchase vary extenders to permit the drone to function further than initially stipulated. However, you also needs to pay consideration to the regulations since, except authorized, you need to at all times fly your drone within visual line of sight.
How sensors work (The IMU system)
Now let’s talk in regards to the various sensors you’ll discover in a drone. But before we try this, it’s necessary to acknowledge that a drone can’t effectively fly without sensors. These devices are as small as the size of an ant, but they’re minicomputers that help measure the surroundings and ship accurate knowledge to the flight controller, which goes a good distance in stabilizing a drone’s flight. The more sensors a drone has, the more it’s going to account for errors or forces that act on the drone as it flies. Let’s have a glance at each of them.
Also generally recognized as MEMS (micro electrical mechanical systems), accelerometers use capacitive and piezoelectric know-how to detect linear acceleration because of gravity. In capacitive expertise, capacitors are placed in a parallel sample. Any change in acceleration forces impacts the distance between these capacitors, affecting their capacitance and sending the signals to the flight controller.
On the opposite hand, piezoelectric measures orientation using microscopic crystals compacted on account of acceleration. A change within the acceleration forces impacts stress, which changes the load and resistance of those crystals. Accelerometers are placed in a 3-axis sample in order that they’ll detect the motion and orientation of a drone in all directions.
Gyroscopes are one other important characteristic that helps stabilize a drone. They consist of a wheel rotating on an axis. This wheel rotates in such a means that, even if the drone tilts, it’s going to nonetheless preserve its stability.
Drones face a extensive range of forces within the air, including wind and gravity. As a outcome, it could become very troublesome to manage the drone, especially when there are huge wind gusts. Gyroscopes are designed to detect all these forces and compensate for them, so the drone will appear unaffected.
Of course, other factors such as the power of the wind and the drone’s weight will apply. But for probably the most part, drones will seem secure in reasonable winds. Gyroscopes also convert these motions into signals and send them to the ESC.
You could have heard of 3-axis gyroscopes and 6-axis gyroscopes. A drone solely wants the 3-axis gyroscopes, but most drone manufacturers will mention a 6-axis gyro as a outcome of they’re taking into account both the gyroscopes and the accelerometers.
Magnetometers measure the magnetic flux alongside the pitch, yaw, and roll axis, which helps detect the drone’s orientation in relation to the magnetic North Pole. When flying in areas with plenty of electromagnetic interference, or another kind of interference, magnetometers assist collect this data and ship it to the flight controller.
Also often recognized as stress sensors, barometers measure the atmospheric pressure to assist determine the drone’s altitude. If you’ve come across a characteristic generally known as altitude hold in most drones on the market, then this is amongst the sensors that make this characteristic possible. Sometimes, barometric sensors work alongside GPS sensors to find out a drone’s altitude and maintain it.
These sensors use lasers, Lidar, or ultrasonic waves to measure the space ahead of a drone and detect any obstacles.
Drone LED lights
All drones come with LED lights. And despite the very fact that they can be seen as decorations, these LED lights serve a function. In most cases, they are used to tell you of the standing of the drone. We have lined lots about drone LED lights in this post, however beneath are the main ones and what they mean.
* Red could imply low battery levels, IMU or other system errors, RTH mode, or agility mode.
* Green can be a standard colour that always reveals the battery ranges are suitable for taking off or for showing that the GPS has related to enough satellites.
* White – White coloured LEDs might imply a poor GPS connection or lack thereof, or that the transmitter is off.
* Blue – Blue can mean Blind Mode or Stability Mode.
* Orange/Yellow – These colours can mean a poor GPS connection or poor compass calibration that must be rectified.
* Purple – This shade is used to indicate Return to Home or Follow-Me modes are working. But if it’s blinking, it might imply there’s a difficulty with these modes. It can additionally be used to indicate AP Mode in some drones.
Below is another sort of LED lights.
* Anti-Collision Lights – Sometimes referred to as navigation lights, these are the lights that make your drone visible from far-off, serving to the operator forestall it from crashing into other drones or other objects. According to the FAA laws, including the recent Remote ID rules, you have to have these lights if you need to fly at night time. They can be blue, pink, white, flashing, or not flashing, depending on the drone mannequin.
Note: Different colors could mean different things depending on the drone you’re using. That’s why it’s necessary to at all times check your specific handbook for tips.
You are after all acquainted with the GPS on your phone or automotive that helps you navigate, however drones have it too. The installation of GPS in drones is amongst the causes drones are in a place to carry out location-based data collection such as surveying and aerial imagery. So, how does it work?
For GPS to work, there needs to be a GPS module or chip placed within the drone and satellites orbiting the earth. Currently, a minimal of 32 GPS satellites orbit the earth, also called the GLONASS (Global Navigation Satellite System). GLONASS is a Russian-based satellite system designed for positioning applications by the navy and civilians.
However, solely about 24 will be functioning at any given time. Now, a drone doesn’t have to connect to all 24 satellites. They want to hook up with a minimum of 8, but the more satellites the module can hook up with, the higher. The module communicates with these satellites to calculate its position.
In the drone apps, there are bars displaying the energy of a GPS connection. And as mentioned earlier, there are even LED lights that will provide you with a warning of any issues with GPS. If your drone doesn’t have access to enough satellites, it may not take off. Some of the explanations you may be getting a poor GPS connection embrace cloud cover, tall timber, tall buildings, or mountains.
Now that you know how GPS works, beneath are a variety of the ways it helps the drone’s functioning.
As mentioned earlier, GPS and barometric sensors might help maintain the drone’s altitude. Some drones include an altitude restrict, and the FAA additionally requires drones to maintain an altitude of lower than four hundred ft. This being the case, GPS might help detect and restrict a drone to a certain altitude.
Also known as position maintain, that is the place a drone takes off and stays in the identical location and altitude till you start feeding instructions into it. This makes it very straightforward even for beginners to fly a drone.
When you’re not sure of the controls, the drone won’t move, it could drift slightly, particularly when it’s windy, however it will always appropriate that.
Return to residence
This is one other quite essential function, especially in emergencies corresponding to low battery levels. Return to house permits the drone to return to the take off point, and one of the simplest ways to do this is to have the coordinates of that location.
That’s why it’s necessary to calibrate the GPS appropriately and permit it to lock the take-off location. When you’ve carried out this, when you provoke the RTH characteristic, you will not lose the drone alongside the greatest way.
Some drones will mechanically provoke the RTH if they lose connection, have low battery ranges, or expertise interference.
Autonomous flying (Waypoints)
A drone can now fly on autopilot due to GPS. How? All you must do is assign waypoints, that are coordinates that the drone can fly via. If you’re using it for filming, mapping, or surveying, you’ll be able to focus on producing high-quality footage while the drone flies by itself.
Like airplanes or ships, drones could be detected by radar. It all boils right down to how radar works. Radar methods are designed to detect bodies emitting radio signals. And as mentioned earlier, drones talk with controllers through radio alerts.
So, you’ll be able to design a system that identifies alerts throughout the drone communication sign ranges and different habits that drones exhibit. As a matter of fact, such techniques already exist. Good examples embody DJI’s Aeroscope, AirSpace Galaxy, and DeDrone.
Internal compass and failsafe options
Drones also have inner compasses which work along with GPS to boost stability and guarantee the drone is in the proper orientation. More typically than not, the compass comes with the GPS module.
When organising a drone, one of the most very important things to do consists of calibrating the compass. Most drones is not going to take off except the compass is calibrated, so ensure you examine how to strive this.
To effectively calibrate the compass, make sure you are in a wide-open area, an space with no magnetic interference and no digital gear. Calibration can additionally be essential whenever you move to a unique location.
Remember, if the compass is incorrectly calibrated, most GPS features, together with finding the satellites, won’t work.
Drone compasses even have magnetometers, which, as I mentioned earlier, will detect any anomalies and help the flight controllers contemplate all elements. All that is to ensure the drone is properly oriented and prevent any fly-aways which may be typically attributable to poor GPS and electromagnetic interference.
Obstacle detection and collision avoidance know-how
When talking about sensors, I mentioned that drones use a variety of applied sciences to detect obstacles. These include LiDAR, monocular imaginative and prescient, time-of-flight, ultrasonic, stereo imaginative and prescient, and infrared.
But that’s a complete lot of sensors., So, how do drones utilize all of them to avoid obstacles? By utilizing a mixture of modeling, algorithms, machine learning, and AI. Algorithms can be trained on how varied objects look, and they’ll “learn” to associate every object they see with what they already know to discover out whether it’s an obstacle or not.
Another fascinating expertise that makes impediment avoidance potential is SLAM (Simultaneous Localization and Mapping). This feature allows drones to map their current setting primarily based on a pre-installed pre-existing environment and the data collected by sensors.
Now, what I’ve simply explained only helps a drone detect an object ahead. But for it to keep away from the object, it will want to calculate where precisely this object is and find an alternative route. One way drones achieve that’s through stereopsis or stereo vision.
You’ll discover that most superior drones will have two cameras on the entrance. Once they get the picture of the item in 2 perspectives, they will calculate the 3D perspective by triangulation. This allows them to view their setting in 3D, perceiving both distance and depth.
Intelligent flight modes
As highlighted several instances in this article, drones are actively amassing data, which might then be used to map out a path that the drone will comply with, with minimal enter from the pilot. With the help of an operating system (more on this later), you can also pre-program various flight patterns that a drone can accomplish on its own. These are also called clever flight modes.
Besides detecting objects, this expertise additionally allows drones to establish objects, also called Follow-Me, or ActiveTrack in DJI drones. As such, you can lock your self as the POI and jog, skate, or take part in any activity, and the drone will observe you whereas filming while additionally avoiding any obstacles along the way.
Other intelligent flight modes include;
* Altitude Hold
* Auto-Return Home
* Position Mode (P-Mode)
* Attitude Mode (ATTI Mode)
* TapFly –
* Quickshots – Dronies, Helix, Circle, Rocket, and so forth.
* Cinematic Mode
Nowadays, drones are designed to communicate their real-time telemetry information to the controller or the app. This includes battery levels, GPS connection, altitude, and different aspects of the drone.
You can also get alerts whenever you exceed an working range, if you fly too high and even whenever you fly in restricted areas. All this information makes it simpler to watch the drone and minimizes crashes.
Geofencing is a characteristic that enforces restrictions and alerts when a drone enters restricted airspace, also identified as No-Fly Zones. These zones include navy bases, the White House, airports, prisons, etc. Unless you discover a way to bypass this restriction, your drone is not going to take off when in these areas.
However, not all drones are restricted by geofencing. For it to work, the drone must have GPS, and it must be integrated with the map containing No-Fly Zones.
Drone working techniques (Firmware)
Drones can most simply be thought of as flying computers. As we’ve established, a lot goes on when a drone takes off and while it’s in the air. There are sensors amassing knowledge, communications with the controller, propellers, batteries, and lots of other functions.
But what powers this complete system? Drones have firmware, often constructed on the Linux operating system, though some use MS Windows. There are also several open-source drone operating techniques that producers can use as a substitute of building one from scratch. These embody;
* Linux’s Dronecode
Drone firmware must be updated regularly to make sure all the drone parts are working as they should, or to introduce new features.
Software and firmware
To successfully fit in in varied industries, there has been increased development of software for drones. Below are some of the hottest industries the place drones are applicable, and the software drones can use.
* Filming and Photography – Lightworks, iMovie, VSDC Free Video Editor, HitFilm Express, and Davinci Resolve.
* Surveying, Mapping, and Aerial Photography – DroneDeploy, Pix4D, ArcGIS, Maps Made Easy, and PrecisionHawk.
* Construction – 3DR, PixPro, and Datumate.
* Agriculture – SLANTRANGE, AgEagle.
Thanks to technological developments, it’s now possible to attach high-quality cameras to drones. As already mentioned, drones now play a serious function in filming and pictures, where we previously wanted helicopters and different expensive equipment.
For a moderate worth, it’s attainable to find a drone that can film in 4K at 30fps. A good example that’s both a interest drone and a professional drone is the DJI Mavic Mini 2. The Mavic sequence, particularly the Mavic Air drones, are some of the greatest images drones for newbies and skilled photographers thanks to their ease of use, extended flight occasions, wonderful cameras, and superior flight control techniques.
Drones like the Autel Robotics EVO II series may even film in 8K decision. And drones like the Inspire collection from DJI feature the Zenmuse X7, which may movie in 6K resolution, and they’ve been instrumental in filming many blockbuster motion pictures.
Besides capturing in high-resolution, some drones also have a zoom characteristic, which allows drones to have a close take a glance at objects, even when they’re at a distance. Depending on the drone you’re using, the zoom feature can both have a gentle loss or lossless zoom. DJI has the Zenmuse Z30 with a zoom of as much as 180x, which is amongst the largest you’ll find in a prosumer drone.

Gimbals and tilt control
As much as drones have superior stability techniques, they are nonetheless not very steady, which might be bad for filming since that movement would make the footage useless. Thankfully, there are gimbals that assist stabilize the cameras regardless of the turbulence.
Even low-cost drones now have gimbals, mostly 3-axis gimbals, that stabilize the cameras in all directions. These gimbals permit for easy, clear pictures, compensating for the movement of the drone.
For these with no gimbals, some are appropriate with third-party gimbal systems.
Live video transmission
It’s now quite common to search out drones that can relay video footage, also called FPV (First Person View).
All of this is made attainable by Wi-Fi connectivity and radio signals between the drone and the controllers. Drones have a transmitter that collects the video footage and sends it as a signal to the controller.
At the opposite finish, the drone will have an antenna or receiver that may receive the signal and convert it to a video that you can view on the smartphone’s display screen. Or you ought to buy FPV goggles that make it feel like you’re sitting within the drone’s cockpit. FPV is also a significant element of drone racing, a fast-growing sport.
Despite being only some years old, there are several drone racing leagues such because the Multi GP and DRL, where drone pilots compete for thousands of dollars and revel in sponsorship offers simply as regular professional athletes. These races are also streamed on reside TV, giving different pilots and hobbyists a view and feel of the adrenaline involved in such a race.
Other drone sensors
One of the most effective issues about drones is the flexibility to hold a payload. Therefore, if you want to prolong its utility and usefulness, all you want to do is find a suitable device to add to the drone, and one of those gadgets is sensors.
Besides the sensors I mentioned earlier that help the drone navigate, you presumably can attach multispectral sensors for agricultural functions, Lidar sensors for development inspection, or thermal sensors for hearth analysis.
Even cameras are sensors that work in seen light. These sensors are hardware, and the info you get from them could be analyzed utilizing the software program I talked about earlier to get significant information crucial in choice making.
Security and hacking
Since they’re flying computers, drones could be hacked, and they may additionally be used to hack into other methods and even spy on other individuals. And the unhealthy information is that it’s not that difficult to hack into a drone.
A hacker can hack into your drone and download footage that you’ve been taking and even use the drone to hack into your house network. They also can hack and take management of the drone by way of a process often known as GPS Spoofing, the place they guide the drone to “false” coordinates. With that in thoughts, under are some methods you probably can prevent your drone from being hacked.
* Firmware upgrades – As mentioned earlier, drone manufacturers replace firmware regularly. To make sure your drone is protected, all the time make sure you’re using the latest firmware.
* Use a VPN to dam your community from being accessed by outsiders.
* Protect your smartphone and laptops with Anti-Virus. When transferring footage between the drone and the smartphone or using the smartphone to regulate the drone, you’re exposing your drone to malware attacks.
* If attainable, manually set the Return to Home level.
* Use a strong password in your app and residential network.
* Limit the number of people using the home network at a given time.
Drone Types and Uses
Now that we all know how drones work, let’s have a glance at the principle forms of drones and how they’re greatest used.
Also often identified as quadcopters, these are the preferred types of drones. They are also the drones I was speaking about when explaining the propulsion system. They have a minimum of 4 rotors, though some of them can have extra rotors.
Their small measurement, agility, velocity, and maneuverability enable them to find functions in plenty of industries, including agriculture, filming, and industrial inspection. The only problem with these drones is the propulsion system consumes plenty of energy. As a result, their batteries don’t final lengthy.
This is another in style type of drone. Unlike the multi-rotor drones which have propellers, these drones have fixed wings, much like those you’ll discover on planes. They need some sort of runway or catapult system to take off. But as soon as they do, they conserve energy, permitting them to fly for long.
They’ve been fairly useful in agriculture, such because the SenseFly drones, and in land survey, such because the Delair drones.
These are merely tiny helicopters that depend on one rotor. They control their pace, roll, pitch, and yaw by adjusting the angle of the rotor. Most of the single-rotor drones you’ll discover are toys. Still, there are additionally bigger superior fashions with the ability to carry heavy payloads, and they can be powered by gas as a substitute of normal batteries.
Hybrid or VTOL drones
VTOL stands for Vertical Take-Off and Landing, that are drones that make the most of the extended flight time of a fixed-wing drone and the vertical taking off and maneuverability of a multirotor. This makes them the most versatile drones, however they are additionally fairly expensive. A good instance is the Wingtra drones, which are very useful in surveying and mapping.
You can even categorize drones based on how they are used, which embody:
* Toy drones
* Consumer drones
* Professional drones
* Racing drones
* GPS drones
Fixed-wing, multi-rotor, single-rotor, and VTOL drones can fit in any of these categories relying on how they are constructed and their options.
