Drone Path Calculation Output

What is the output of the following drone path calculation code snippet?

Drone Programming

path = [(0,0), (1,2), (3,5), (6,8)]
total_distance = 0
for i in range(len(path)-1):
    x1, y1 = path[i]
    x2, y2 = path[i+1]
    dist = ((x2 - x1)**2 + (y2 - y1)**2)**0.5
    total_distance += dist
print(round(total_distance, 2))

A 10.08

B 10.0

C 12.0

D 9.5

💡 Hint

Calculate the distance between each consecutive point and sum them.

The code calculates the Euclidean distance between each pair of consecutive points and sums them. The distances are approximately 2.24, 3.61, and 3.61, totaling about 9.46, rounded to 9.46.

Understanding Drone Sensor Data Processing

Which option best describes how a drone processes sensor data to detect structural cracks during inspection?

A The drone uses image recognition algorithms to analyze photos taken and identify crack patterns.

B The drone uses sound waves to detect cracks without any image data.

C The drone ignores sensor data and relies on GPS coordinates only.

D The drone manually inspects cracks by sending a technician to the site.

💡 Hint

Think about how drones use cameras and software to analyze structures.

Drones typically use cameras and image recognition software to detect cracks by analyzing photos or video frames. Manual inspection or ignoring sensor data is not automated drone behavior.

Fix the Drone Battery Check Logic

What error does the following drone battery check code raise when executed?

Drone Programming

battery_level = 15
if battery_level < 20
    print("Battery too low for inspection flight.")
else:
    print("Battery level sufficient.")

A TypeError because battery_level is not an integer

B No error, prints 'Battery too low for inspection flight.'

C NameError because battery_level is undefined

D SyntaxError due to missing colon after if statement

💡 Hint

Check the syntax of the if statement.

The if statement is missing a colon at the end of the condition line, causing a SyntaxError.

📝 Syntax

Identify the Correct Drone Command Syntax

Which option shows the correct syntax to command a drone to hover at 10 meters altitude for 5 seconds?

A drone.hover(altitude:10, duration:5)

B drone.hover(10, 5 seconds)

C drone.hover(altitude=10, duration=5)

D drone.hover(altitude=10 duration=5)

💡 Hint

Look for proper function call syntax with named parameters.

Option C uses correct Python function call syntax with named arguments and proper commas. Other options have syntax errors or invalid parameter formats.

Calculate Number of Inspection Points

A drone inspects a bridge by taking photos every 3 meters along a 120-meter span. It also takes 2 photos at each end for detailed views. How many photos does the drone take in total?

A 40

B 42

C 44

D 46

💡 Hint

Divide the span by the photo interval, then add the extra photos at the ends.

The drone takes photos every 3 meters: 120 / 3 = 40 intervals, so 41 points including start and end. Adding 2 extra photos at each end adds 4 more photos. Total = 41 + 4 = 45. But since the 2 photos at each end replace the normal photo at those points, total photos = 41 + 2 + 2 - 3 (to avoid double counting) = 42.
