AI in Agricultural Robotics and Robotic Weeding Quiz

Answers and explanations appear as you take the quiz.

1. Which pressures does the guide say push growers away from broadcast herbicide spraying?
   • Too much rainfall and cheap chemicals
   • Herbicide-resistant weeds, rising chemical costs and labor shortages for hand weeding
   • A ban on all farm machinery
   • Declining demand for vegetables
2. John Deere's See & Spray is built on technology from which company?
   • Blue River Technology, acquired by Deere in 2017
   • Carbon Robotics
   • Naïo
   • Tevel
3. What does 'green-on-green' detection refer to?
   • Detecting any green plant on bare soil
   • Measuring chlorophyll in the crop
   • Distinguishing weeds from crop plants growing right beside them
   • Painting weeds a different color
4. Why do targeted sprayers run inference on onboard GPUs rather than in the cloud?
   • Cloud computing is illegal on farms
   • GPUs make the nozzles spray more
   • Onboard GPUs are required to read GPS
   • The system must fire the nozzle within a tight latency budget while moving at field speed
5. Why do herbicide savings from spot spraying vary so widely between fields?
   • Because nozzles wear out at different rates
   • Because savings depend on weed density, and heavily infested fields save little
   • Because cameras work only at night
   • Because weeds are always evenly spread
6. Where must a laser weeder aim to kill a weed effectively?
   • At the weed's growing point, the meristem
   • At the soil beside the weed
   • At the crop plant
   • At the top of the tallest leaf only
7. What does the sensitivity threshold on many see-and-spray systems let farmers trade off?
   • Tractor speed against fuel use
   • Crop yield against market price
   • Missed weeds against extra spraying
   • Camera resolution against battery life
8. Why is harvest automation less mature than robotic weeding?
   • Fruit is easier to detect than weeds
   • Harvest robots do not need computer vision
   • Farmers do not want to harvest crops
   • Robots must find fruit hidden by leaves, judge ripeness and grasp without bruising
