Speed control during mission in Drone Programming - Mini Project: Build & Apply

Speed control during mission

📖 Scenario: You are programming a drone to fly a mission. The drone must adjust its speed based on the distance to the next waypoint to fly safely and efficiently.

🎯 Goal: Build a program that sets the drone's speed for each waypoint based on the distance to that waypoint.

📋 What You'll Learn

Create a dictionary with waypoints and their distances

Add a speed limit variable

Use a loop to set speed based on distance

Print the speed settings for each waypoint

💡 Why This Matters

🌍 Real World

Drones need to adjust their speed during missions to save battery and avoid obstacles safely.

💼 Career

Understanding how to control speed based on conditions is important for drone software developers and robotics engineers.

1

Create waypoints with distances

Create a dictionary called waypoints with these exact entries: 'WP1': 100, 'WP2': 250, 'WP3': 400, 'WP4': 150

Drone Programming

# Your code here

Need a hint?

Use curly braces to create a dictionary with the waypoint names as keys and distances as values.

2

Set maximum speed limit

Create a variable called max_speed and set it to 50 to represent the maximum speed of the drone.

Drone Programming

waypoints = {'WP1': 100, 'WP2': 250, 'WP3': 400, 'WP4': 150}
# Your code here

Need a hint?

Just assign the number 50 to the variable max_speed.

3

Calculate speed for each waypoint

Use a for loop with variables wp and dist to iterate over waypoints.items(). Inside the loop, create a variable called speed that is max_speed if dist is greater than 200, otherwise dist / 4.

Drone Programming

waypoints = {'WP1': 100, 'WP2': 250, 'WP3': 400, 'WP4': 150}
max_speed = 50
# Your code here

Need a hint?

Use a conditional expression to set speed based on the distance.

4

Print speed settings

Inside the same for loop, write a print statement that outputs: "Waypoint {wp} speed set to {speed}" using an f-string.

Drone Programming

waypoints = {'WP1': 100, 'WP2': 250, 'WP3': 400, 'WP4': 150}
max_speed = 50
for wp, dist in waypoints.items():
    speed = max_speed if dist > 200 else dist / 4
    # Your code here

Need a hint?

Use print(f"Waypoint {wp} speed set to {speed}") inside the loop.
