B A robot arm sprays paint on a car in a factory

3. What do robots in a warehouse move?

A Crops that are growing in a field

B Stock, such as boxes and shelves of goods

4. Why does a self-driving car need sensors?

A To detect obstacles such as people and other cars

B To store the music the passengers like

5. A warehouse robot's sensor detects a box in its path. What should it do?

B Drive straight into the box

Match the Pairs

Draw a line connecting each item on the left to its match on the right.

Left column		Right column
1driverless_car.detect(obstacle)		AA driverless car with no sensors cannot detect obstacles, so it could crash into people or other vehicles

3A warehouse robot moves stock from a shelf to the packing area		CA delivery drone flies a parcel to a customer's address, moving goods without a human driver
4A sensor on a transport robot stops it when an obstacle is too close		DIF distance < 1 THEN stop()
5driverless_car.drive() // no sensors fitted		EA self-driving car uses its sensors to detect an obstacle on the road so it can avoid it
6warehouse_robot.move(stock) // no destination		FThe warehouse robot has no destination, so it does not know where to carry the stock

Answer Key

Role of robots in transport

Section A: Quick Questions

B — A driverless car that moves passengers

A — A delivery drone carries a parcel to a house

B — Stock, such as boxes and shelves of goods

A — To detect obstacles such as people and other cars

A — Stop or steer around the obstacle

Section B: Match the Pairs

driverless_car.detect(obstacle) → A self-driving car uses its sensors to detect an obstacle on the road so it can avoid it

drone.deliver(parcel, address) → A delivery drone flies a parcel to a customer's address, moving goods without a human driver

A warehouse robot moves stock from a shelf to the packing area → warehouse_robot.move(stock, packing_area)

A sensor on a transport robot stops it when an obstacle is too close → IF distance < 1 THEN stop()

driverless_car.drive() // no sensors fitted → A driverless car with no sensors cannot detect obstacles, so it could crash into people or other vehicles

warehouse_robot.move(stock) // no destination → The warehouse robot has no destination, so it does not know where to carry the stock

Section C: Definitions

robots in transport — Robots move people and goods, for example driverless cars, delivery drones and warehouse robots, using sensors to detect obstacles.

Section D: Fill in the Blanks

IF obstacle = TRUE THEN
   stop_car()
ENDIF

IF distance < 2 THEN
   hover()
ENDIF

WHILE parcels_left > 0 DO
   carry_to_van()
ENDWHILE

obstacle ← read_sensor()
IF obstacle = TRUE THEN stop_car() ENDIF

IF blocked = TRUE THEN turn()
ELSE go_on()
ENDIF

Section E: Spot the Error

B — A motor is an actuator, not a sensor. The self-driving car must read the distance from a sensor, so the line should be READ distance FROM sensor.

C — The delivery drone is meant to climb to 50. Subtracting 5 makes the altitude fall, so the loop never ends. It should be altitude ← altitude + 5.

D — After picking up the item, the warehouse robot must carry it to the packing area. Moving to the shelf again means the stock never gets there. It should be move_to(packing).

B — The robot should stop when the obstacle sensor shows something CLOSE, meaning a small distance. d > 3 stops it when the obstacle is far away. It should be IF d < 3 THEN.

C — When the battery is above 20 the delivery drone has enough power to start its delivery. It should take off, not land. The line should be takeoff().
