Quick Questions

Shade in the A or B circle for each question.

1. Which statement about a drone is correct?

A A drone is just a toy that has no electrical parts or program

B A drone is a flying robot with a frame, rotors, electrical parts and a program

2. Which part of a drone is its mechanical structure?

A The frame and rotors

B The microprocessor and sensors

3. What do the sensors on a drone do to help it stay level in the air?

A They spin to make the drone fly upwards

B They measure its tilt and position and send the data to the microprocessor

4. What does the microprocessor do when a sensor shows the drone is tilting?

A It processes the sensor data and tells the motors to change speed

B It measures the tilt itself and turns the rotors directly

5. Which drone is flying by remote control?

A A drone whose movements are steered by a person using a handset

B A drone that follows a route stored in its program with no one steering

Answer Key

Example robot: drones

Section A: Quick Questions

B — A drone is a flying robot with a frame, rotors, electrical parts and a program

A — The frame and rotors

B — They measure its tilt and position and send the data to the microprocessor

A — It processes the sensor data and tells the motors to change speed

A — A drone whose movements are steered by a person using a handset

Section B: Match the Pairs

rotors → The spinning blades turned by motors that push air down and lift the drone into the air

IF tilt_sensor = "left" THEN speed_up_right_rotors → A sensor reading is used by the program to adjust the rotors and keep the drone level

An autonomous drone follows a programmed route without a pilot, so it still counts as a robot → FOR each waypoint IN route: fly_to(waypoint)

A remote-controlled drone is flown by a human pilot who sends commands from a handset → IF stick_pushed = "forward" THEN move_forward

A drone is a robot because it has wings and no electrical parts → A drone has a frame and rotors, not wings, and it needs electrical components such as sensors, a microprocessor and motors to be a robot.

A drone flown only by remote control with no program is a robot → A drone needs a program that controls its flight to be a robot, because the microprocessor must run instructions.

Section C: Definitions

drone — A flying robot with a frame and rotors, sensors, a microprocessor and motors, and a program that controls its flight, either by remote control or by following a programmed route.

Section D: Fill in the Blanks

FOR rotor ← 1 TO 4
   spin(rotor)
NEXT rotor

IF tilt > 0 THEN
   correctTilt()
ENDIF

INPUT command
IF command = "UP" THEN
   climb()

WHILE battery > 20
   flyTo(nextPoint)
ENDWHILE

hasFrame ← TRUE
hasElectrics ← TRUE
isRobot ← hasFrame AND hasElectrics

Section E: Spot the Error

D — A sensor only gathers data. The motors are the actuators that change the rotor speeds to level the drone, so line 4 should be ADJUST motors.

A — The frame material is text, so it must be in quotes. Without the quotes the program treats carbon and fibre as variable names. It should be frame ← "carbon fibre".

A — The drone must receive the chosen mode (remote control or programmed route), so line 1 should be INPUT mode. OUTPUT would only display a value that does not exist yet.

C — The drone is climbing to 30 m, so the altitude must increase. Subtracting would make the loop run forever. It should be altitude ← altitude + 5.

B — An IF statement needs the keyword THEN at the end of the condition. Line 2 should be IF tilt > 0 THEN.
