Inspection of infrastructure in Drone Programming - Mini Project: Build & Apply

Inspection of Infrastructure

📖 Scenario: You are programming a drone to inspect a set of infrastructure points such as bridges, towers, and pipelines. The drone needs to check each point's status and decide if it requires maintenance based on a damage score.

🎯 Goal: Build a simple program that stores infrastructure points with their damage scores, sets a damage threshold, filters points that need maintenance, and prints the list of points requiring maintenance.

📋 What You'll Learn

Create a dictionary with infrastructure points and their damage scores

Set a damage threshold value

Use a loop or comprehension to find points needing maintenance

Print the list of points that require maintenance

💡 Why This Matters

🌍 Real World

Drones inspecting infrastructure help find problems early to keep bridges, towers, and pipelines safe.

💼 Career

This project shows how to process sensor data and make decisions, skills useful for drone programming and maintenance automation jobs.

1

Create infrastructure data

Create a dictionary called infrastructure with these exact entries: 'Bridge A': 3, 'Tower B': 7, 'Pipeline C': 5, 'Bridge D': 2, 'Tower E': 8

Drone Programming

# Create the dictionary 'infrastructure' with the given points and damage scores
# Your code here

Hint

Use curly braces {} to create a dictionary with keys as point names and values as damage scores.

2

Set damage threshold

Create a variable called damage_threshold and set it to 5

Drone Programming

infrastructure = {'Bridge A': 3, 'Tower B': 7, 'Pipeline C': 5, 'Bridge D': 2, 'Tower E': 8}
# Create the variable 'damage_threshold' and set it to 5
# Your code here

Hint

Just assign the number 5 to the variable damage_threshold.

3

Find points needing maintenance

Create a list called needs_maintenance that contains the names of points from infrastructure where the damage score is greater than damage_threshold. Use a list comprehension with point and score as variables in for point, score in infrastructure.items()

Drone Programming

infrastructure = {'Bridge A': 3, 'Tower B': 7, 'Pipeline C': 5, 'Bridge D': 2, 'Tower E': 8}
damage_threshold = 5
# Create the list 'needs_maintenance' using a list comprehension
# Your code here

Hint

Use a list comprehension to check each score and include the point if the score is greater than damage_threshold.

4

Print points needing maintenance

Write a print statement to display the list needs_maintenance

Drone Programming

infrastructure = {'Bridge A': 3, 'Tower B': 7, 'Pipeline C': 5, 'Bridge D': 2, 'Tower E': 8}
damage_threshold = 5
needs_maintenance = [point for point, score in infrastructure.items() if score > damage_threshold]
# Print the list 'needs_maintenance'
# Your code here

Hint

Use print(needs_maintenance) to show the points that need maintenance.

Practice

1. What is the main purpose of using a drone's inspect() function in infrastructure inspection?

easy

A. To control the drone's speed during flight

B. To repair damaged parts of the infrastructure

C. To send the drone to a specific location for inspection

D. To charge the drone's battery automatically

Solution

1. Step 1: Understand the function purpose

   The inspect() function is designed to send the drone to a location for inspection.

2. Step 2: Compare options with function role

   Only To send the drone to a specific location for inspection matches the purpose of sending the drone to inspect infrastructure.

3. Final Answer:

   To send the drone to a specific location for inspection -> Option C

4. Quick Check:

   inspect() sends drone to location = A [OK]

Hint: Remember: inspect() means 'go check there' [OK]

Common Mistakes:

• Confusing inspect() with repair functions
• Thinking inspect() controls speed
• Assuming inspect() charges battery

2. Which of the following is the correct syntax to capture an image during a drone inspection?

easy

A. drone.captureImage()

B. drone.capture-Image()

C. drone.captureimage()

D. drone.capture_image()

Solution

1. Step 1: Identify correct method naming style

   In drone programming, method names use lowercase with underscores for readability.

2. Step 2: Match options to correct style

   drone.capture_image() uses capture_image(), which is the correct syntax.

3. Final Answer:

   drone.capture_image() -> Option D

4. Quick Check:

   Method names use underscores = D [OK]

Hint: Use underscores for multi-word method names [OK]

Common Mistakes:

• Using camelCase instead of snake_case
• Omitting underscores between words
• Using invalid characters like hyphens

3. What will be the output of this code snippet?

drone.inspect('bridge')
image = drone.capture_image()
print(image)

medium

A. SyntaxError

B. 'bridge_image.jpg'

C. None

D. 'image captured'

Solution

1. Step 1: Understand the inspect and capture_image functions

   The inspect('bridge') sends the drone to the bridge, and capture_image() takes a photo and returns the filename.

2. Step 2: Analyze the print output

   Printing image shows the filename string, which is 'bridge_image.jpg'.

3. Final Answer:

   'bridge_image.jpg' -> Option B

4. Quick Check:

   capture_image() returns filename = C [OK]

Hint: capture_image() returns filename string [OK]

Common Mistakes:

• Expecting a boolean or None instead of filename
• Confusing print output with status messages
• Assuming syntax error without checking code

4. Identify the error in this drone inspection code:

drone.inspect('tower')
image = drone.captureImage()
print(image)

medium

A. Method name should be capture_image(), not captureImage()

B. Missing parentheses after inspect

C. print() cannot print variables

D. inspect() requires two arguments

Solution

1. Step 1: Check method names for correct syntax

   The method captureImage() is incorrect; it should be capture_image() using underscores.

2. Step 2: Verify other code parts

   inspect('tower') is correct with parentheses and one argument; print() can print variables.

3. Final Answer:

   Method name should be capture_image(), not captureImage() -> Option A

4. Quick Check:

   Method names use underscores = A [OK]

Hint: Check method names carefully for underscores [OK]

Common Mistakes:

• Using camelCase instead of snake_case
• Thinking print() can't print variables
• Assuming inspect needs two arguments

5. You want the drone to inspect multiple infrastructure points and save images with names matching each point. Which code correctly does this?

points = ['bridge', 'tower', 'dam']
images = {}
for point in points:
    drone.inspect(point)
    images[point] = drone.capture_image()
print(images)

hard

A. {'bridge': 'bridge_image.jpg', 'tower': 'tower_image.jpg', 'dam': 'dam_image.jpg'}

B. ['bridge_image.jpg', 'tower_image.jpg', 'dam_image.jpg']

C. {'bridge_image.jpg', 'tower_image.jpg', 'dam_image.jpg'}

D. SyntaxError due to missing colon in for loop

Solution

1. Step 1: Understand the loop and dictionary usage

   The code loops over points, inspects each, and stores the image filename in a dictionary with the point as key.

2. Step 2: Predict the dictionary content after loop

   Each key is the point name, and value is the image filename matching that point, e.g. 'bridge_image.jpg'.

3. Final Answer:

   {'bridge': 'bridge_image.jpg', 'tower': 'tower_image.jpg', 'dam': 'dam_image.jpg'} -> Option A

4. Quick Check:

   Dictionary keys = points, values = filenames = B [OK]

Hint: Use dictionary to map points to images [OK]

Common Mistakes:

• Using list instead of dictionary for mapping
• Forgetting colon after for loop
• Confusing set notation with dictionary
