Technology and Uses of Drones

Drones, or UAVs, are unmanned aerial vehicles initially used for military purposes but have gained commercial popularity. Modern drones use a multi-rotor design for lift and steering, controlled via radio waves. They are used in various fields, including media and delivery services, and are expected to become more prevalent in daily life.

What is a key characteristic of UAVs that differentiates them from other aerial vehicles?

• They have a human pilot inside.

• They cannot fly autonomously.

• They are controlled by a computerized system or remotely.

• They are only used for military purposes.

What is the primary function of the multi-rotor design in drones?

• To reduce the weight of the drone.

• To increase the speed of the drone.

• To make the drone more aerodynamic.

• To provide lift and help steer the drone.

How do drones typically receive commands from their controllers?

• Through infrared signals.

• Using radio waves.

• Through a wired connection.

• Via satellite signals.

In what way is the multi-rotor design particularly beneficial for photography and videography?

• It provides a steady flight path.

• It allows for faster flight speeds.

• It reduces battery consumption.

• It enables drones to carry heavier cameras.

Which of the following is a modern application of drones?

• Only military reconnaissance.

• Delivering packages to homes.

• Only for shooting movies.

• Exclusively for toy models.
