In recent times, all of you might have heard this technological term ” drone camera “. But do you know what is this drone in the true sense ? How does it work?
If you do not know the answers to all these questions, then there is nothing to worry because today we are going to discuss about this state-of-the-art gadget. As strange as it sounds in hearing, it seems equally strange in appearance.
In true sense it is a robot which can be controlled by humans. But it is a flying robot. It has been prepared by humans only for editing their works.
Then do not wait any longer, let’s start and know about what is a drone and how it works.
What is a drone?
What does drone mean? Drones are also called UAVs or Unmanned aerial vehicles . Actually these are only miniature robots which are capable of flying. Wherein they are controlled with the help of a remote control system.
For Army or Military people, these are UAVs ( Unmanned Aerial Vehicles ) or RPAS ( Remotely Piloted Aerial Systems ). Wherein they are commonly called “drones”.
They can monitor 24 hours a day, or even a whole week. Each drone can monitor for a long time and send you all real-time imagery. That’s why it is also called “eye of the sky”.
Drone technology is constantly evolving day by day with the help of new innovations. Unmanned aerial vehicle technology includes everything such as the aerodynamics of the drone, the materials used to make it, the circuit boards, chipset and software , which is also called the brain of the drone.
What is Quadcopter?
This quadcopter is a very common and popular flying drone design. It is a type of drone that uses four rotors to lift and propel.
Although the concept of quadcopter is not new, as they have been experimented before in the year 1920 , but due to lack of right technology at that time, its effectiveness had to bear heavy losses.
But with the advancement of electronic technology such as sensors, batteries, cameras and GPS systems, these quadcopters are now being widely used.
What does drone camera mean?
Talking about drone camera, it is a flying machine made by humans with technology, which can be flown from the earth without any pilot. It is controlled from mobile, computer or any remote. Drone camera is useful in many places today.
How does the drone fly?
The four propellers of the drone are fixed and oriented vertically. Each propeller has a variable and independent speed that allows it to cover a full range of movements.
Different drones have different propeller combinations which help them achieve different drone movements.
These are not like conventional helicopters which are controlled with propellers blades and which pitch dynamically around the rotor hub.
The components that are needed to make the blade pitch are very expensive, that’s why these quadcopters are now being used more.
How to make drone?
1. Chassis
This is the skeleton of the drone by which all the components are fixed. While designing these chassis design, their strength (this is when any additional weight like camera is attached) and additional weight is kept in mind, because otherwise longer propellers and stronger motors may be required to lift them. For.
2. Propellers
This often affects the load of the quadcopter, how much load it can lift, how fast it can fly and how fast it can maneuver around.
Their length can be modified; Longer propellers can easily lift more weight that too in lower rpm but they take little more time to speed up or speed down.
Whereas smaller propellers can change their speed more easily and are therefore more manoeuvrable, but they require more rotational speed to achieve the same power as longer blades.
Due to this there is excess strain on the motor and due to which their lifespan is reduced.
We can say that a more aggressive pitch may provide quicker movement but it reduces the hovering efficiency to a great extent.
3. Motors
Each propeller has 1 motor, drone motors are rated on “Kv” units which means the number of revolutions per minute it achieves when a voltage of one volt is supplied to the motor without any load.
A faster motor spin may provide more flight power, but it also requires more power from the battery, resulting in a reduction in flight time.
4. Electronic Speed Controller (ESC)
It provides a controlled current to each motor to generate the correct spin speed and direction.
5. Flight Controller
This is called the onboard computer that interprets the incoming signals sent by the pilot and then sends the corresponding inputs to the ESC, which controls the quadcopter.
6. Radio Receiver
It receives control signals which are sent by the pilot.
7. Battery
Lithium polymer batteries are generally used in this because they have high power density and the ability to be recharged.
Along with this, many sensors can also be used such as accelerometers, gyroscopes, GPS and barometers for positional measurements. Wherein Cameras are often mounted for navigation and aerial photography.
how does a drone work
A typical unmanned aircraft is made of very light composite materials to reduce weight and increase control.
This composite material gives strength to these drones so that they can fly very high for military purposes.
Drones are laced with many different technologies such as infrared cameras, GPS and laser (they are in all types whether it is consumer, commercial or military UAV).
Drones are controlled with the help of remote ground control systems (GSC) and also called a ground cockpit.
Basically, an unmanned aerial vehicle system has two parts, the drone itself and its control system.
All the sensors and navigational systems are located in the front part of the drone. Whereas all the drone technology systems are located in the rest of the body because there is no place to keep humans in them.
The engineering materials that are used to make them are highly complex composites , which are specially designed to absorb the vibrations being generated, thereby reducing the noise generated. Is. These materials are very light weight.
type of drone
Although there are many types of drones, but they are mainly divided into two parts.
- Rotary Drone
- Fixed Wing Drone
Rotary Drone
These rotary drones also have different types.
1. Single Rotor
There is only a single rotor located in it. At the same time, there is a tail rotor at the rear which provides it with control and stability.
2. Tricopter
It consists of three different types of powerful motors, three controllers, four gyros and one servo motor.
3. Quadcopter
Four rotor blades are used in this. In this brushless type DC motors are used. In this, two motors rotate clockwise, while two motors rotate anti-clockwise. Lithium Polymer Batteries are used.
4. Hexacopter
In these 6 rotor blades are used. In which 3 motors rotate clockwise, while 3 motors rotate anti-clockwise. Their landing is the safest.
5. Octacopter
In this, 8 functional propellers are used with 8 motors. It naturally has high flying capability, while its stability is the best.
Fixed Wing Drone
This is a completely different type of drone. Their design is also quite different from multi-rotor designs. In this you can see wings like a traditional place. At the same time, they are not very stable in the air and along with this, gravitational force seems to have more effect on their movement. At the same time, they cannot lift more weight than quadcopters.
What is VTOL Drones?
VTOL drones can easily take off, fly, hover and land vertically. The full form of VTOL is ” Vertical Take-Off and Landing “.
What is Drone – UAV Technology?
By the way, many advanced technology is used in Drone. About which many of you may not know anything. So let’s get some information about them.
Radar Positioning And Return Home technology
Many of the latest drones include dual Global Navigational Satellite Systems (GNSS) such as GPS and GLONASS.
Drones can fly in both GNSS and non-satellite modes.
It is very important to have highly accurate drone navigation while flying, as it is needed in many applications such as creating 3D maps, surveying landscape and SAR (Search & Rescue) missions.
Now let’s know how it works
When the drone is switched on, it searches and detects GNSS satellites. These high-end GNSS systems use Satellite Constellation technology . Basically, this satellite constellation is a group of satellites that are working together and which have coordinated coverage and are synchronized so that they can overlap and provide the right coverage.
Pass or coverage is the period when a satellite is visible above the local horizon.
Whereas the radar technology located in the Drone sends the below mentioned signals to the remote controller display;
- Many drone GNSS satellites of signal have been detected and drone is now ready to fly
- Displaying the correct position and location with your pilot
- Simultaneously recording the home point. This is for ‘Return To Home’ safety feature
What are the types of Return to Home Drone Technology?
Most of the latest drones mainly follow 3 types of Return to Home drone technology;
1. Return to home initiated by pilot in which button is pressed in remote control or app.
2. Due to the low battery level, where the UAV will automatically fly to its home point location.
3. Even if there is a loss of transmission between the drone and the remote controller, the drone will still fly to its home point location.
Obstacle Detection And Collision Avoidance Technology
Collision avoidance systems are now being installed in many drones. These drone vision systems use obstacle detection sensors to scan the surroundings, while using software algorithms and SLAM technology, the images can be converted into 3D maps so that the flight controller can know about the upcoming objects. He goes so that he can avoid accidents.
These systems use the following sensors to sense obstacles and avoid them;
- Vision Sensor
- Ultrasonic
- Infrared
- Lidar
- Time of Flight (ToF)
- Monocular Vision
These drones have such features that they can sense and actively attempt to avoid obstacles so that they can return home easily.
By the way, let us now know how this obstacle avoidance technology works when the lighting is sufficient;
1. When an obstacle is detected, the drone automatically slows down.
2. Then they stop and start hovering, then fly backward and start rising up, then they keep going up until they feel that there is no obstacle in front.
3. Then the RTH process starts and the drone returns to its home location.
Gyro Stabilization, IMU and Flight Controllers
Gyro stabilization technology is the component that gives the drone its smooth flight capabilities.
These gyroscopes have to act immediately, that too contrary to the forces that are working against the drone.
This gyroscope provides all essential navigational information to the central flight controller.
The full form of IMU is inertial measurement unit (IMU). It works by detecting the current rate of acceleration and for this it uses one or more accelerometers.
This IMU detects any change in its rotational attributes such as pitch, roll and yaw, for this it uses one or more gyroscopes.
Some IMUs also have a magnetometer built in to help them calibrate against orientation drift.
This Gyroscope is a component of IMU and IMU is an essential component of drones flight controller. This flight controller is the central brain of the drone.
Drone Motor Direction and Propeller Design
Here motors and propellers are those drone technology, which move the drone in the air and help it to hover in any place.
They receive data from the flight controller and electronic speed controllers (ESC) that provide the correct direction to the drone motor to hover and fly.
Onscreen Real-Time Flight Parameters
Most drones have a Ground Station Controller (GSC) or a smartphone app that allows you to track current flight telemetry.
No Fly Zone Drone Technology
To increase flight safety and keep them away from restricted areas, a “ No Fly Zone ” feature is being installed in many new drones.
These no-fly zones are divided into two categories: A and B.
Manufacturers can easily update and change this no-fly zone drone technology with firmware updates.
GPS Ready To Fly Mode Drone Technology
When the compass is calibrated, the drone searches for the location of the GPS satellites. And when 6 or more are found, then it allows the drone to fly in ” Ready To Fly ” mode.
Internal Compass and Failsafe Function
This allows the drone and remote control system to know the exact flight location. Compass calibration is required to set a home point.
This home point is the location where the drone returns when there is a loss of signal between the drone and the remote control system. This is called “fail-safe function”.
Firmware and Flight Assistant Port
These flight control systems communicate with a PC assistant, that too through a Micro-USB cable. This allows in the configuration of the drone as well as to upgrade the drone firmware.
A simple definition of Drone is that it is a flying computer with a camera and some sensors. Like computers, drones also have firmware software that sends commands to the physical components of the aircraft and remote controller.
Drone manufacturers release new firmware upgrades to fix bugs and add new features to the aircraft, remote control unit and software if they are needed to fly the drone.
LED Flight Indicators
You can see them in the front and rear part of the drone. Generally, drone LEDs are of green, yellow or red colour .
Where the front LEDs are to indicate where the front of the drone is located. Whereas the rear LEDs flight indicators are used to indicate the different status of the drone such as when the power is on, when the firmware upgrade is happening and when it is flying.
All drones come with a user manual, which explains the meaning of each flashing LED light .
High-Performance Camera
The latest drones are equipped with cameras that can shoot HD photos and videos, some even have the facility of recording 4k videos.
Gimbals AND Tilt Control
Gimbal technology is a very important technology when it comes to quality aerial photography. Using this, quality aerial photos, film and 3D imagery can be easily captured.
This gimbal prevents any kind of vibration from reaching the camera. Along with this gimbal also helps you to tilt the camera so that the best photos can be taken even while flying.
Practically all the latest drones already have integrated gimbals and cameras. This changes the definition of photography itself.
How can you fly the drone?
A drone is controlled manually by a hand-held radio control transmitter which manually controls the propellers.
Sticks in the controller allow you to move in different directions and trim buttons allow the trim to be adjusted so that the drone can be balanced.
Screens can also be used to receive live video footage from on-board cameras and display sensor data there.
Apart from this, the on-board sensors also provide many helpful settings such as;
Auto altitude where the drone moves in a fixed altitude;
GPS hold, where the drone is stabilized in a fixed GPS position .
Drones can also be flown autonomously, nowadays modern flight controllers use software that already marks GPS waypoints as to how a drone is going to fly, where it is going to land and where its destination point is. But it is situated etc.
how does the drone fly
A very important feature of drones is their flight time. A simple answer to the above question is that where better quality drones can fly up to 30 minutes , cheap drones fly only for 5 to 10 minutes.
By the way, there can be many reasons behind how long a drone can fly above such as: –
1. How much is Battery Life
Batteries come in many types depending on the sizes and types of drones. It is only natural that a battery of better quality can provide more backup , while it is a matter to remember that over time, batteries also start deteriorating slowly if they are not maintained properly.
Lithium Batteries are capable of giving backup for a long time.
2. Drone का Weight
Flying depends on how big your drone is and how many motors and propellers are attached to it, as well as how much it weighs. Because in this the batteries have to do more work to keep the whole vehicle in the air.
Drones which are made of light weight materials can fly for a long time.
3. Availability of Add-Ons
The weight of the drone is not only limited to its own weight but also depends on all the gadgets attached to it. This is because drones are rarely sent empty-handed, but cameras, sensors, recorders, etc. are also attached to them.
The heavier its add-ons, the less time it can fly.
How to keep the drone in the air for a long time?
Till now you have understood the basic principle of drones, along with that you have also come to know how it works. Now let us know how we will increase its flight time.
1. If your drone is equipped with a lithium-polymer battery , use it sparingly in cold environments as cold has a negative effect on the battery’s efficiency and causes it to discharge sooner.
2. At the same time, it should not fly in the hot area because by flying it there, the motor of the drone has to do more work to lift the drone. Due to which the battery charge will end soon. So leave the battery to cool down first and then charge it again.
3. At the same time, they should not be flown in a windy place as it requires more energy to stabilize the drone and also there is a fear of colliding with other buildings and trees.
4. Water is not good for drones at all. That’s why never fly drones in humid climate. This can reduce the flight time of drones.
5. Keep them away from unnecessary add ons and apply only those add ons which you need.
6. If you are using guards then it will protect them from accident but it increases their weight. Therefore, as soon as you become experienced in flying them, do not forget to remove these guards.
7. Fly them at high speeds for a very short time because by doing so their battery drains quickly. On the other hand, if you do not want to use it for some time, then store it fully charged and that too in room temperature in a dry and ventilated area.
If you follow these tips, then you can increase the flight time of your drone, as well as protect it from damage.
What are the Applications of Drones?
There are many applications of flying drones such as: –
- Automatic pollination in grain fields
- Carrying out his work in many search and rescue operations
- To do traffic monitoring
- In exploring Hazardous Sites
- To do military surveillance
- to mapping the weather
- To do aerial photography
- Even to provide Drone-delivery services
- Sport – to do drone racing
Who was the inventor of the drone?
Nikola Tesla is considered the inventor of the drone, it is said that in 1915 he had made such a combat drone which we could control from one place and attack the enemies.
How high can the drone fly?
These drone cameras equipped with smart features can fly up to a height of 50 meters .
What does drone mean?
An unmanned aircraft is called a drone . It is controlled from a remote location.
