Pre-flight checklist automation in Drone Programming - Mini Project: Build & Apply

Pre-flight checklist automation

📖 Scenario: You are preparing a drone for flight. To ensure safety, you need to check several important systems before takeoff. Automating this checklist helps avoid mistakes and saves time.

🎯 Goal: Build a simple program that stores the drone's system checks, sets a threshold for passing, filters which checks passed, and then displays the final list of passed checks.

📋 What You'll Learn

Create a dictionary called system_checks with exact keys and values for system names and their status scores

Create a variable called pass_threshold with the exact value 75

Use a dictionary comprehension called passed_checks to include only systems with scores greater than or equal to pass_threshold

Print the passed_checks dictionary exactly as shown

💡 Why This Matters

🌍 Real World

Automating pre-flight checks helps drone operators quickly verify that all important systems are ready, improving safety and efficiency.

💼 Career

Knowledge of filtering data and using dictionary comprehensions is useful for software developers working on automation, robotics, or embedded systems.

1

Create the system checks dictionary

Create a dictionary called system_checks with these exact entries: 'Battery': 80, 'Motors': 90, 'Sensors': 70, 'GPS': 85, 'Camera': 60

Drone Programming

# Create the system_checks dictionary with exact entries
# Your code here

Need a hint?

Use curly braces {} to create the dictionary with the exact keys and values.

2

Set the pass threshold

Create a variable called pass_threshold and set it to the integer 75

Drone Programming

system_checks = {'Battery': 80, 'Motors': 90, 'Sensors': 70, 'GPS': 85, 'Camera': 60}
# Set pass_threshold to 75
# Your code here

Need a hint?

Just assign the number 75 to the variable pass_threshold.

3

Filter passed system checks

Use a dictionary comprehension called passed_checks to include only the systems from system_checks where the score is greater than or equal to pass_threshold

Drone Programming

system_checks = {'Battery': 80, 'Motors': 90, 'Sensors': 70, 'GPS': 85, 'Camera': 60}
pass_threshold = 75
# Create passed_checks dictionary comprehension
# Your code here

Need a hint?

Use {system: score for system, score in system_checks.items() if score >= pass_threshold} to filter.

4

Display the passed checks

Print the passed_checks dictionary exactly as it is

Drone Programming

system_checks = {'Battery': 80, 'Motors': 90, 'Sensors': 70, 'GPS': 85, 'Camera': 60}
pass_threshold = 75
passed_checks = {system: score for system, score in system_checks.items() if score >= pass_threshold}
# Print passed_checks
# Your code here

Need a hint?

Use print(passed_checks) to show the filtered dictionary.
