Companion computer integration (Raspberry Pi) in Drone Programming - Mini Project: Build & Apply

Companion Computer Integration with Raspberry Pi for Drone Control

📖 Scenario: You are building a simple program on a Raspberry Pi that acts as a companion computer for a drone. The Pi will read sensor data, decide if the drone should take action, and send commands accordingly.This project simulates reading sensor values, setting a threshold, filtering sensor data, and printing commands to control the drone.

🎯 Goal: Create a program that stores sensor readings, sets a threshold for action, filters sensor data above the threshold, and prints commands to the drone based on filtered data.

📋 What You'll Learn

Create a dictionary called sensor_data with exact sensor names and values

Create a variable called threshold with the exact value 50

Use a dictionary comprehension to create filtered_data with sensors having values above threshold

Print the filtered_data dictionary

💡 Why This Matters

🌍 Real World

Companion computers like Raspberry Pi help drones process data and make decisions independently from the main flight controller.

💼 Career

Understanding how to filter and process sensor data on companion computers is important for drone software developers and robotics engineers.

1

Create sensor data dictionary

Create a dictionary called sensor_data with these exact entries: 'altitude': 45, 'temperature': 55, 'battery': 80, 'speed': 30

Drone Programming

# Create the sensor_data dictionary with exact sensor readings
# Your code here

Need a hint?

Use curly braces {} to create a dictionary with keys and values separated by colons.

2

Set threshold value

Create a variable called threshold and set it to the integer 50

Drone Programming

sensor_data = {'altitude': 45, 'temperature': 55, 'battery': 80, 'speed': 30}
# Create the threshold variable and set it to 50
# Your code here

Need a hint?

Just assign the number 50 to the variable threshold.

3

Filter sensor data above threshold

Use a dictionary comprehension to create a dictionary called filtered_data that includes only the sensors from sensor_data with values greater than threshold

Drone Programming

sensor_data = {'altitude': 45, 'temperature': 55, 'battery': 80, 'speed': 30}
threshold = 50
# Create filtered_data using dictionary comprehension
# Your code here

Need a hint?

Use {key: value for key, value in dict.items() if condition} to filter dictionary entries.

4

Print filtered sensor data

Print the filtered_data dictionary to display sensors with values above the threshold

Drone Programming

sensor_data = {'altitude': 45, 'temperature': 55, 'battery': 80, 'speed': 30}
threshold = 50
filtered_data = {sensor: value for sensor, value in sensor_data.items() if value > threshold}
# Print filtered_data
# Your code here

Need a hint?

Use print(filtered_data) to show the filtered dictionary.
