Answer Key

What a robot is

Section A: Quick Questions

A — A machine that carries out tasks automatically by following a program

A — No, it can look like an arm, a vacuum or a drone

B — No, a person controls each action

A — A robot arm that welds car parts by following a program

B — A program

Section B: Match the Pairs

robot → A machine that carries out tasks automatically by following a program, usually without a person controlling each action

automatic task → A job the machine does by itself, following its program, without a person controlling each step

A robot does not have to look like a human. A robot arm that welds car parts is still a robot. → robot_arm = Robot("welding")

A real robot follows a stored program to act on its own, unlike a film robot that is only acted or animated. → while True: run_program()

A robot must always look like a person. → Robots do not need a human shape. Many real robots, such as factory arms and robot vacuum cleaners, look nothing like people.

A robot needs a person to control every action. → A robot works automatically by following a program, usually without a person controlling each action.

Section C: Definitions

robot — A machine that carries out tasks automatically by following a program, usually without a person controlling each action. It does not have to look human.

Section D: Fill in the Blanks

WHILE floorIsDirty = TRUE
  CALL cleanFloor()
ENDWHILE

mode ← "automatic"

IF obstacleAhead = TRUE THEN
  CALL turnAway()
ENDIF

FOR step ← 1 TO 4
  CALL flyForward()
NEXT step

IF batteryLevel < 20 THEN
  CALL returnToCharger()
ENDIF

Section E: Spot the Error

D — The machine has a program and no person controls each action, so it is a robot. The THEN branch should output "Robot".

B — A robot carries out tasks automatically by following a program. The mode should be "automatic", not "manual".

A — A robot does not have to look human. The test should be whether the machine runs a program (runsProgram), not what it looks like.

C — This line describes real robots, so it must use realRobot (follows a program). filmRobot describes the film version, which is not how real robots work.

B — A robot works by following a program, so programmed should be TRUE. With FALSE the machine would not carry out the task automatically.
