Quick Questions

Shade in the A or B circle for each question.

1. A factory robot welds 1,000 car doors. Which statement is true?

A Every weld is made with the same accuracy

B Welds get less accurate as the day goes on

2. Why can a robot keep working through the night?

A It does not get tired and needs no breaks

B It needs to sleep, but only for one hour

3. Which is an advantage of using robots for repetitive work?

A They do not lose concentration

B They get bored and make more mistakes

4. A company wants to make more products each day. How can robots help?

A They work slowly, so productivity falls

B They work faster for longer, so productivity rises

5. A human worker is on a long shift. What is likely to happen to the quality of their work?

A It will always stay perfect

B It may drop as they get tired

Answer Key

Advantage of robots: consistent and continuous work

Section A: Quick Questions

A — Every weld is made with the same accuracy

A — It does not get tired and needs no breaks

A — They do not lose concentration

B — They work faster for longer, so productivity rises

B — It may drop as they get tired

Section B: Match the Pairs

consistent work → A robot repeats a task with the same accuracy every time, so every product has the same quality

continuous work → A robot can run 24 hours a day without tiredness, breaks or loss of concentration

A car factory robot welds every door with the same accuracy, so every car has the same quality → for each door: weld(point1, point2, point3)

A packing robot works all night with no breaks and no loss of concentration, so more items are produced → while power_on: pack(item)

Robots get tired after 8 hours, so they must stop for a rest break like workers. → Robots do not get tired or lose concentration. They can work for long periods without breaks, apart from maintenance or recharging.

A robot welds a little differently each time, so the quality of each product varies. → A robot repeats a task with the same accuracy every time, so the quality does not vary. Variation is a human problem.

Section C: Definitions

consistent and continuous work — A robot repeats a task with the same accuracy every time and works for long periods without tiredness or breaks, so it raises productivity.

Section D: Fill in the Blanks

WHILE power = ON DO
   weldPanel()
ENDWHILE

FOR i ← 1 TO 1000
   paintDoor()
NEXT i

robotTired ← FALSE
OUTPUT robotTired

partsPerHour ← 30
total ← partsPerHour * 24
OUTPUT total

REPEAT
   checkPart()
UNTIL power = OFF

Section E: Spot the Error

C — The robot works all 24 hours, so the total must grow every hour. The line should be made = made + 10. Setting made = 10 throws away the earlier work.

D — The variable is called size, so print(siz) causes a NameError. It should be print(size). The robot makes every part exactly the target size.

B — A while statement must end with a colon. It should be while hours < 24: so the robot keeps making parts for 24 hours.

A — A function definition must end with a colon. It should be def weld_part(): so the robot can repeat the same weld each time.

A — The variable name goes on the left of the assignment and the value on the right. It should be parts_per_hour = 60.
