Q & A

What are the primary uses of drones in today's world?

Drones are used for filming, military, surveillance, and recreational activities.

What is the intersection of fields that drones belong to?

Drones belong to the intersection of aerospace, robotics, and mechatronics.

What is another term for drones?

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

In what types of situations are drones typically used?

Drones are primarily used in situations that are too dry, distant, dull, or dangerous for human pilots.

What is the first and most important part of a commercially available drone?

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

What materials are commonly used for drone frames and what are their advantages?

Frames are typically made from plastic or carbon fiber. Carbon fiber is preferred for its strength and minimal weight.

How does the weight of a drone frame affect its performance?

The heavier the frame, the less lift can be achieved, but a super lightweight frame might break upon impact.

What is the role of motors in a drone and how are they selected?

Motors provide the power for each blade or arm of the drone. They are selected based on required power and the intended use of the drone.

What are propellers in a drone and what materials are they commonly made from?

Propellers are the wings of the drone and can be made from plastic or carbon fiber, with carbon fiber being more durable but also more expensive.

How does the size of a drone's propeller affect its performance?

Smaller propellers are chosen for more aggressive builds, while larger ones are used for higher payload and longer flight time builds.

What is the source of power for a drone and how does battery capacity affect its weight?

The power for a drone comes from its batteries, which vary in weight and capacity. As capacity increases, so does the weight.

What is the function of the electronic speed controller in a drone?

The electronic speed controller controls the speed of the motors, ensuring they do not all run at the same speed, which would result in constant hovering.

How do the Transmitter and Receiver facilitate communication in a drone?

The Transmitter sends signals to the Receiver, which is connected to the flight controller, delivering inputs and then outputting responses to the motors.

What is the role of the flight computer in controlling a drone's movement?

The flight computer uses algorithms and codes to take directions into consideration and apply the necessary power to each propeller for smooth and controlled movement.
