Receiving telemetry data in Drone Programming - Mini Project: Build & Apply

Receiving telemetry data

📖 Scenario: You are programming a drone that sends telemetry data about its position and battery level. You want to receive this data and process it step-by-step.

🎯 Goal: Build a program that receives telemetry data as a dictionary, sets a battery warning threshold, filters the telemetry data to find values below the threshold, and then prints the warnings.

📋 What You'll Learn

Create a dictionary called telemetry_data with keys 'altitude', 'speed', and 'battery' and values 120, 45, and 15 respectively.

Create a variable called battery_warning_level and set it to 20.

Use a dictionary comprehension called warnings to include only telemetry items where the value is less than battery_warning_level.

Print the warnings dictionary.

💡 Why This Matters

🌍 Real World

Drones send telemetry data to ground stations to monitor flight status and safety.

💼 Career

Understanding how to receive and filter telemetry data is important for drone software developers and engineers working with real-time sensor data.

1

Create telemetry data dictionary

Create a dictionary called telemetry_data with these exact entries: 'altitude': 120, 'speed': 45, and 'battery': 15.

Drone Programming

# Create the telemetry_data dictionary with altitude, speed, and battery
# Your code here

Need a hint?

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

2

Set battery warning level

Create a variable called battery_warning_level and set it to 20.

Drone Programming

telemetry_data = {'altitude': 120, 'speed': 45, 'battery': 15}
# Set battery_warning_level to 20
# Your code here

Need a hint?

Just assign the number 20 to the variable battery_warning_level.

3

Filter telemetry warnings

Use a dictionary comprehension called warnings to include only items from telemetry_data where the value is less than battery_warning_level.

Drone Programming

telemetry_data = {'altitude': 120, 'speed': 45, 'battery': 15}
battery_warning_level = 20
# Create warnings dictionary with items below battery_warning_level
# Your code here

Need a hint?

Use {key: value for key, value in telemetry_data.items() if value < battery_warning_level}.

4

Print warnings

Print the warnings dictionary.

Drone Programming

telemetry_data = {'altitude': 120, 'speed': 45, 'battery': 15}
battery_warning_level = 20
warnings = {key: value for key, value in telemetry_data.items() if value < battery_warning_level}
# Print the warnings dictionary
# Your code here

Need a hint?

Use print(warnings) to show the filtered dictionary.
