Applications of Drones
Question
Consider the following activities: At the present level of technology, which of the above activities can be successfully carried out by using drones?
- 1.
Spraying pesticides on a crop field
- 2.
Inspecting the craters of active volcanoes
- 3.
Collecting breath samples from spouting whales for DNA analysis
Options
1 and 2 only
2 and 3 only
1 and 3 only
1, 2 and 3
Explanation
Agricultural drones are extensively used today for precision spraying of pesticides (Statement 1). Unmanned Aerial Vehicles (UAVs) are routinely deployed to safely inspect extreme environments like active volcanic craters (Statement 2). Researchers use specialized drones (nicknamed 'SnotBots') to hover over whales and collect biological material from their blowholes for DNA analysis (Statement 3). > One-line conceptual takeaway: Drone technology is heavily utilized for remote sensing and physical interaction in hazardous or inaccessible environments. Answer: (d).
