Quick Questions

Shade in the A or B circle for each question.

1. Which job is a robot doing in agriculture?

A A robot arm with a camera picks ripe strawberries

B A robot arm welds a car door in a factory

2. Which device is used to spray crops from the air?

B A crop-spraying drone

3. True or false: a robotic milking machine can milk cows without a farmer doing it by hand.

A False

B True

4. Which is a way sensors help robots to monitor crops?

B Soil sensors move the plants into rows

5. Which is the best example of a robot used for monitoring crops?

Answer Key

Role of robots in agriculture

Section A: Quick Questions

A — A robot arm with a camera picks ripe strawberries

B — A crop-spraying drone

B — True

A — Soil sensors measure moisture so the right amount of water is used

A — A drone with sensors that checks the health of a field

Section B: Match the Pairs

fruit-picking robot → Uses a camera sensor to spot ripe fruit and a robotic arm to pick it gently without bruising it

crop-spraying drone → Flies over fields to spray water, fertiliser or pesticide on crops, covering large areas quickly

A robotic milking machine milks cows automatically using sensors to find the cow's udder, so farmers do not need to milk by hand → milkingRobot.attachToCow()

Soil sensors monitor crops by measuring moisture and send the readings to a microprocessor, which decides if watering is needed → IF soilMoisture < 30 THEN waterCrops()

Fruit-picking robots plant the seeds in the field → Fruit-picking robots harvest (pick) ripe fruit. They do not plant seeds, which is a different farm job done by planting robots.

Farmers must walk the fields to check soil moisture because robots cannot monitor crops → Robots can monitor crops and soil using sensors, and they send the data to a microprocessor, so walking the fields is not needed.

Section C: Definitions

agricultural robot — A robot that does farm jobs such as planting, picking, spraying and monitoring crops, e.g. fruit-picking robots, spraying drones, milking machines and soil sensors.

Section D: Fill in the Blanks

arm.pick(ripe_fruit)
arm.place(basket)

drone.spray(crops)
drone.return_home()

machine.milk(cow)
machine.clean()

level = sensor.read_soil()

IF moisture > 80 THEN
  pump.off()
ENDIF

Section E: Spot the Error

A — An IF statement needs THEN after its condition. The line should be IF soil_moisture < 30 THEN so the farm robot knows when to start watering.

B — The fruit-picking robot starts at 0, so fruit > 50 is false and it would never pick anything. The condition should be fruit < 50.

A — A count-controlled loop uses the keyword TO, not OF. The line should be FOR row ← 1 TO 10 so the spraying drone covers rows 1 to 10.

D — This replaces the running total with one cow's yield each time. It should add to the total: milk ← milk + yield(cow).

C — DO is used for loops. An IF statement must use THEN, so the line should be IF moisture < 30 THEN.
