Quick Questions

Shade in the A or B circle for each question.

1. Which list gives the three characteristics of a robot?

A Mechanical structure, a screen, a keyboard

B Mechanical structure, electrical components, a program

2. A device has a metal frame and a motor and is powered by a circuit, but it has no program. Is it a robot?

A No, because it has no program

B Yes, because it has a frame and a motor

3. A robot vacuum cleaner has a body, motors, sensors, circuits and a program. Which statement is correct?

A It is not a robot because it is used at home

B It is a robot because it has all three characteristics

4. Which exam answer describes a robot using the three headings?

A It has a mechanical structure (arm), electrical components (motors, sensors) and a program that controls it

B It is a machine that is very fast, very strong and never needs to be switched off

5. A toy car is made of plastic and has a battery and a motor. It is driven by a remote and has no program. Which is true?

A It is missing one characteristic, so it is not a robot

B It has two characteristics, so it counts as a robot

Answer Key

The three characteristics of a robot together

Section A: Quick Questions

B — Mechanical structure, electrical components, a program

A — No, because it has no program

B — It is a robot because it has all three characteristics

A — It has a mechanical structure (arm), electrical components (motors, sensors) and a program that controls it

A — It is missing one characteristic, so it is not a robot

Section B: Match the Pairs

mechanical structure + electrical components + program → The three characteristics a device must have together to count as a robot

mechanical structure + electrical components + NO program → Not a robot, because one of the three characteristics is missing (it cannot be programmed)

Describing a robot using the three headings in an exam answer → Mechanical structure: metal arm | Electrical components: motors, sensors | Program: instructions it follows

Missing one characteristic means the device is not a robot → has_structure = True has_electrical = True has_program = False is_robot = has_structure AND has_electrical AND has_program

A toaster has a metal body and electrical parts, so it is a robot. → It has no program that controls its actions, so one characteristic is missing. All three are needed.

A robot only needs a program to be a robot: is_robot = has_program → A robot needs all three characteristics, not just a program. It also needs a mechanical structure and electrical components.

Section C: Definitions

mechanical structure + electrical components + program — A device is a robot only if it has all three: a mechanical structure, electrical components and a program. If any one is missing, it is not a robot.

Section D: Fill in the Blanks

IF structure AND electrical AND program THEN
  OUTPUT "Robot"
ENDIF

IF program = FALSE THEN
  OUTPUT "Not a robot"
ENDIF

count ← 3
IF count = 3 THEN
  OUTPUT "Robot"

FOR i ← 1 TO 3
  OUTPUT characteristic[i]
NEXT i

IF NOT electrical THEN
  OUTPUT "Not a robot"
ENDIF

Section E: Spot the Error

A — A device is a robot only if it has all three characteristics (mechanical structure, electrical components and a program), so needed should be 3, not 2.

D — OR would accept a device with only one characteristic. All three are needed, so the line should use AND: IF mech AND elec AND prog THEN.

C — The comment says a toaster has no program, so prog should be FALSE. Because one characteristic is missing, the toaster is not a robot.

A — This block returns a value (TRUE or FALSE) and ends with ENDFUNCTION, so it must start with FUNCTION, not PROCEDURE.

C — Wheels are not one of the three characteristics, because a robot can move in other ways. The second characteristic is electrical components.
