Keywords

💡Drones

Drones, also known as Unmanned Aerial Vehicles (UAVs), are aircraft without a human pilot on board. They are controlled either autonomously by computers in the vehicle or remotely by a pilot on the ground. In the context of the video, drones are highlighted for their use in various fields such as filming, military, surveillance, and recreational activities, showcasing their versatility and importance in modern technology.

💡Aerospace

Aerospace is the human effort in science, engineering, and business to fly in the atmosphere of Earth (aeronautics) and surrounding space (astronautics). The script mentions that drones fall under the intersection of aerospace, indicating that they are part of the broader field of technologies and industries that deal with flight within and beyond Earth's atmosphere.

💡Robotics

Robotics is an interdisciplinary branch of engineering and science that includes the design, construction, operation, and use of robots. In the video, drones are part of this field, as they incorporate robotic elements such as automation and the ability to perform tasks without human intervention, particularly in situations deemed too dangerous for human pilots.

💡Mechatronics

Mechatronics is the synergistic combination of precision mechanical engineering, electronic engineering, and software engineering in the design and manufacture of intelligent robotic and机电一体化 systems. The script points out that drones are an intersection of mechatronics, highlighting the integration of mechanical, electronic, and software components in their design.

💡Unmanned Aerial Vehicles (UAV)

Unmanned Aerial Vehicles, or UAVs, are pilotless aircraft that are guided by remote control or onboard computers. The video uses this term interchangeably with 'drones' to emphasize the unmanned nature of these vehicles and their use in various applications where human presence might be risky or impractical.

💡Frames

In the context of drones, the frame refers to the structural component that holds all the parts together, including the motors, propellers, and electronic components. The script discusses how frames are typically made from materials like plastic or carbon fiber, and their importance in determining the drone's weight and flight characteristics.

💡Motors

Motors are the components that convert electrical energy into mechanical energy to power the propellers and enable flight. The script explains that each blade or arm of a drone has a separate motor, and the choice of motor depends on the required power and the intended use of the drone, such as carrying heavy payloads or providing agile maneuverability.

💡Propellers

Propellers are the rotating airfoils that create thrust by moving air. In the video, they are described as the 'wings' of the drone, made from materials like plastic or carbon fiber, with the latter being more durable but also more expensive. The size and choice of propellers are crucial for the drone's performance, affecting factors like flight time and payload capacity.

💡Batteries

Batteries are the energy storage devices that power drones. The script notes that batteries come in various weights and capacities, and their selection is a balance between providing sufficient power for flight and maintaining a manageable weight for the drone.

💡Electronic Speed Controller (ESC)

The Electronic Speed Controller is a device that controls the speed of an electric motor by managing the amount of electrical current supplied to it. In the video, the ESC is highlighted as a critical component that ensures the motors can spin at different speeds to achieve various flight maneuvers rather than just hovering.

💡Transmitter and Receiver

The transmitter and receiver are communication devices used in drones to send and receive signals between the operator and the drone. The script explains that the transmitter sends control signals, and the receiver, connected to the flight controller, interprets these signals to adjust the drone's movements, allowing for precise control during flight.

💡Flight Controller

A flight controller is the central processing unit of a drone that manages its flight dynamics and stability.

Transcripts

In today's modern world, drones are used for many reasons, including filming, military

surveillance and recreational activities.

Drones fall under an intersection of aerospace, robotics, and mechatronics.

They can range from entirely autonomous military-grade drones to your average remote-controlled drones

you might see a kid flying in the park.

Another name for drones is Unmanned Aerial Vehicles, or UAV.

These machines are primarily used in situations where the conditions are too dry, distant,

dull or dangerous for human pilots.

However, the term drone can be highly misleading, as there are many different kinds.

Today, we will be talking about popular drones available for recreational use.

The first and most important part of a commercially available drone is the frame.

Frames are typically made from plastic or carbon fiber and can be arranged with different

arm variations.

The end of each arm houses the motor and propeller, while the center holds the flight controllers,

gimbals, and other electronic gear, such as cameras.

Most of the weight should be at the center, as this leads to the best flight characteristics.

Weight matters, as the heavier the frame, the less lift can be achieved.

However, you also don’t want a super lightweight frame that will break upon impact.

Carbon fiber is preferred for its strength and minimal weight.

Next are the motors.

There is a separate motor for each blade or arm.

Motor decisions are based on required power, and what you want the motor to do.

If a multi-rotor is being built to carry heavy payloads and maintain the best possible flight

times, then a slower-spinning, higher torque motor is ideal.

However, you may want an aggressive, fast system with lots of maneuverability and faster-spinning

rotor systems.

Propellers are the wings of the drone, and can be made from plastic or carbon fiber.

Carbon fiber is the more durable choice, but it's also more expensive.

The size of the propeller should also match your intended purpose.

If you wish to have a more aggressive build, choose smaller propellers.

The opposite is true for higher payload, longer flight time builds.

The power of the drone comes from its batteries, which come in a wide variety of weights and

capacities.

As the capacity of the battery increases, so does its weight.

There is a certain point where more capacity is no longer beneficial, and the benefits

begin to diminish.

The system that controls the drone is the electronic speed controller, which will run

the motors you have.

Since the motors are constantly spinning at different speeds, they need a speed controller

to dictate that speed to them.

If the motors all ran at the same speed, you would always be hovering.

The Transmitter and Receiver help in communication between the drone and the person controlling

it.

The transmitter “transmits” the signal and the receiver “receives” it.

The receiver is connected to the flight controller; it delivers these inputs and then outputs

the responses to the motors.

The algorithm and codes built into the flight computer take all of your directions into

consideration and apply the necessary power to each propeller to achieve smooth and controlled

movement.

Now, the next time you go out to fly your drone, you’ll know exactly how much planning

and delicate technology is involved!
