Communication between drones in Drone Programming - Mini Project: Build & Apply

Communication between drones

📖 Scenario: You are programming a group of drones that need to share messages with each other to coordinate their tasks. Each drone has a unique ID and can send messages to other drones in the group.

🎯 Goal: Build a simple program that stores messages sent between drones and shows the messages received by each drone.

📋 What You'll Learn

Create a dictionary called drones with drone IDs as keys and empty lists as values to hold messages.

Create a variable called message with the text to send.

Write a loop that sends the message from one drone to another by adding it to the receiver's message list.

Print the messages received by each drone.

💡 Why This Matters

🌍 Real World

Drones often need to share information like location, status, or commands to work together safely and efficiently.

💼 Career

Understanding how to manage communication between devices is important for roles in robotics, automation, and IoT (Internet of Things) development.

1

Set up drones with empty message lists

Create a dictionary called drones with these exact keys: "drone1", "drone2", and "drone3". Each key should have an empty list [] as its value.

Drone Programming

# Create the drones dictionary with empty message lists
# Your code here

Need a hint?

Use curly braces {} to create a dictionary. Each drone ID is a key with an empty list [] as the value.

2

Create a message to send

Create a variable called message and set it to the string "Hello from drone1".

Drone Programming

drones = {
    "drone1": [],
    "drone2": [],
    "drone3": []
}
# Create the message variable
# Your code here

Need a hint?

Use = to assign the string to the variable message.

3

Send the message from drone1 to drone2 and drone3

Use a for loop with the variable receiver to go through the list ["drone2", "drone3"]. Inside the loop, add the message to the list of messages for each receiver in the drones dictionary.

Drone Programming

drones = {
    "drone1": [],
    "drone2": [],
    "drone3": []
}
message = "Hello from drone1"
# Send the message to drone2 and drone3
# Your code here

Need a hint?

Use append() to add the message to each receiver's list.

4

Show messages received by each drone

Use a for loop with variables drone and messages to go through drones.items(). Inside the loop, print the drone ID and its messages in this exact format: "drone1 received: []".

Drone Programming

drones = {
    "drone1": [],
    "drone2": [],
    "drone3": []
}
message = "Hello from drone1"
for receiver in ["drone2", "drone3"]:
    drones[receiver].append(message)
# Print messages received by each drone
# Your code here

Need a hint?

Use an f-string to format the print output exactly as shown.
