Quick Questions

Shade in the A or B circle for each question.

1. Which is part of a robot's mechanical structure?

A A robot arm with joints

B The robot's program code

2. What does the mechanical structure of a robot do?

A Holds the parts together and lets the robot move

B Stores the instructions the robot follows

3. A program running on a laptop that can plan a route but has no body. Is it a robot?

A Yes, a program alone is a robot

B No, it has no mechanical structure

4. Which robot part is an example of a joint?

A The elbow of a factory robot arm

B The microprocessor chip

5. A wheeled vacuum cleaner robot moves around a room. Which part of its mechanical structure lets it travel?

A Its sensors

B Its wheels

Answer Key

Characteristic of a robot: mechanical structure or framework

Section A: Quick Questions

A — A robot arm with joints

A — Holds the parts together and lets the robot move

B — No, it has no mechanical structure

A — The elbow of a factory robot arm

B — Its wheels

Section B: Match the Pairs

robot.frame = "steel body" → Sets the frame, the body that holds the robot's parts together

robot.wheels = 4 → Gives the robot four wheels so that it can move across the ground

A joint is a mechanical part that lets a robot arm bend and turn → robot.arm.joint = "elbow"

A robot must have a physical body, not just a program → hasMechanicalStructure = True

robot = "program only" hasBody = False → A program with no physical body is not a robot, because every robot needs a mechanical structure.

structure = "the robot's software" → The mechanical structure is the physical frame, arms, joints or wheels. It is not the software.

Section C: Definitions

mechanical structure — The physical body or framework of a robot, such as its frame, joints, arms or wheels, that holds its parts together and lets it move. A program alone is not a robot.

Section D: Fill in the Blanks

IF hasFrame = TRUE THEN
    OUTPUT "Could be a robot"
ENDIF

IF hasFrame = FALSE THEN
    isRobot ← FALSE
ENDIF

wheels ← 4
joints ← 2
OUTPUT wheels

IF wheels > 0 THEN
    OUTPUT "Structure lets it move"
ENDIF

hasProgram ← TRUE
hasFrame ← FALSE
isRobot ← hasProgram AND hasFrame

Section E: Spot the Error

D — Every robot has a mechanical structure (frame, joints, arms or wheels). It should be hasStructure <- TRUE.

C — A robot needs a physical structure AND a program. With OR, a program alone would count as a robot. It should use AND.

D — Wheels are part of the mechanical structure and let the robot move. Thinking is done by the microprocessor. It should say 'move'.

C — Joints are part of the mechanical structure and let the arm bend and move. They do not store data. It should say the joints let the arm bend.

C — A program is not a physical part, so it is not part of the mechanical structure. Wheels, a frame, joints or arms belong in the list.
