How does a Drone work and Fly?
Owning a drone is fun and useful at the same time. Shooting a video from a camera fitted on it can help with those Instagram views and take commercial videos at work. Alternatively, you could take it out in your backyard and enjoy a quiet Sunday afternoon.
However, what if the drone does not function efficiently? What if it doesn’t take flight smoothly or isn’t moving in the direction intended?
In these times, it is essential to know how a drone works and flies. More importantly, you can let your kid in the fun of learning too. This way, they’ll understand a drone's functioning and the importance of handling a device with care.
What you will learn while constructing a drone
We have STEM learning kits if you are building a drone, including the build-it-yourself Quadcopter Kit. It is a controllable rotorcraft motor with a Microduino Joypad. You can make it along with your child and learn how to construct a wireless-controlled drone.
While building a drone, you will understand the motor and propeller design. You will need the Quadcopter motor configuration, matching propellers, and electronic speed control circuits, among other systems.
A drone has a feature to attach a payload to it like a camera, time-of-flight, or a Lidar sensor. If you are wondering what a payload is, it’s the part of the transmitted data that becomes the intended message. For instance, the Lidar sensor is meant to capture imagery, which, when attached, the drone will do the same during flight.
Flying with a different payload will impact the drone’s control, flight, and balance. Therefore, additional payload requires different quadcopter motor thrusts accordingly.
While using our STEM products, your kid will learn the mechanism involved in the signals transmitted.
The movement on the remote control stick will send signals to the central flight controller. This signal will direct its motors to increase or decrease the speed required during take-off and flight. This central flight controller will share this information with the Electronic Speed Controllers.
How does a quadcopter fly?
Much like a ceiling fan, a drone uses rotors for propulsion. The spinning blades push the air downward, while the air pushes up on the rotor. That is because all forces come in pairs, controlling the upward and downward pressure; Physics!
A drone functions by executing three actions in the vertical plane:
§ Hover: The net thrust of the four rotors pushes the drone upward, but this force has to be equal to the gravitational force pulling it downward to stay and hover at the same level.
Climb: The thrust or speed of the rotors is increased, thus   enabling the drone to move upward in a vertical direction.
Descend: Reducing the speed of the thrust will allow the drone to   descend.
Now, imagine wanting to move the drone sideways. It’s time to switch your imagination from a ceiling fan to a car.
However, moving a drone sideways or forward and backward would mean controlling the rear rotors, specifically rotor 3 and 4. Simply increase the speed of the rear rotors while decreasing the rate of rotors 1 and 2. It’s a matter of also increasing and reduced speeds in the rotors that will help you understand how to fly the drone.
