Quick Questions

Shade in the A or B circle for each question.

1. Which job is a typical role for a robot in industry?

A Welding car body parts on an assembly line

B Deciding which new car design to sell

2. Why are robots used for spray painting car bodies?

A The fumes are harmful to humans, and the robot paints every car the same way

B Robots are paid less than humans, so they never need maintenance

3. Which task is a robot in a factory most suited to?

4. Which place is best suited to a robot rather than a human worker?

A A quiet, safe office with no dangers

B A hot, hazardous area such as a furnace room

5. True or false: On a car assembly line, robots can assemble parts repeatedly in the same way.

Answer Key

Role of robots in industry

Section A: Quick Questions

A — Welding car body parts on an assembly line

A — The fumes are harmful to humans, and the robot paints every car the same way

A — Lifting heavy loads again and again all day

B — A hot, hazardous area such as a furnace room

B — True

Section B: Match the Pairs

robot.weld(car_body) → A factory robot joins metal parts of a car together, a repetitive and dangerous job done safely by a machine

robot.spray_paint(car_door) → A factory robot paints a car part evenly, so humans avoid breathing in harmful paint fumes

Industrial robots can lift heavy loads again and again without getting tired or injured → robot.lift(heavy_engine)

Industrial robots can work in hot or hazardous places where it is unsafe for humans → robot.work_in(furnace_room)

Industrial robots are only used to serve food in restaurants. → Industrial robots work in factories on repetitive or dangerous manufacturing tasks such as welding, painting, assembling and packing, not serving food.

A car assembly line uses robots because they are paid wages and need rest breaks. → Robots are used because they do repetitive or dangerous tasks safely and without tiredness, and they do not need wages or rest breaks.

Section C: Definitions

industrial robot — A robot used in factories to do repetitive or dangerous jobs such as welding, spray painting, assembling and packing, often on car assembly lines or in hot, hazardous places.

Section D: Fill in the Blanks

WHILE lineRunning = TRUE
  robot.weld(carDoor)
ENDWHILE

robot.spray(carBody, "red")

FOR n ← 1 TO 500
  robot.pack(box)
NEXT n

IF hazardous = TRUE THEN
  robot.enter()
ENDIF

robot.lift(heavyLoad)

Section E: Spot the Error

A — A FOR loop needs the keyword TO between the start and end values. It should be FOR panel ← 1 TO 4, so the welding robot repeats the weld on each of the 4 panels.

B — The closing bracket is missing from the spray painting command. It should be robot.spray_paint(red) so the painting robot can run the instruction.

C — Industrial robots are used in hot, hazardous places so that people are not put at risk. The lifting should be done by robot.lift(casting), not by a human.

A — A WHILE loop needs the keyword DO at the end of the first line. It should be WHILE car_on_line = TRUE DO, so the welding robot repeats the task on every car on the line.

C — The counter goes down instead of up, so it never reaches 10 and the packing robot would never stop. It should be items ← items + 1.
