💻 Code Challenges

Write code to solve these challenges. Test your solutions and get hints if you need help!

Challenge 1: Safe Takeoff Function

Write a function that checks the battery level before taking off. The function should:

Check if battery is above 30%
If yes, take off and hover for 2 seconds
If no, print a warning message

def safe_takeoff(drone):
    # Your code here
    pass

💡 Hint: Use drone.get_battery() to check battery level, then use an if statement to decide whether to take off.

Challenge 2: Obstacle Detection

Write a function that makes the drone move forward until it detects an obstacle within 50cm:

Use a while loop
Check front range sensor continuously
Stop when obstacle is detected

def avoid_obstacle(drone):
    # Your code here
    pass

💡 Hint: Use while distance > 50: to keep moving forward, and update the distance inside the loop.

Challenge 3: Square Flight Pattern

Write code to make the drone fly in a square pattern:

Take off and hover
Move forward, turn right, repeat 4 times
Land safely

drone = Drone()
drone.pair()
# Your code here

💡 Hint: Use a for loop with range(4) to repeat the forward and turn movements.

📖 Step-by-Step Tutorials

1 Understanding Drone Basics

Before programming, you need to understand the basic components:

Drone object: Represents your physical drone
Pairing: Establishes connection between code and drone
Safety checks: Always check battery before flight

2 Your First Flight

Let's write your first flight program:

from codrone_edu.drone import *

drone = Drone()
drone.pair()
drone.takeoff()
drone.hover(2)
drone.land()
drone.close()

This program pairs, takes off, hovers for 2 seconds, then lands.

3 Adding Safety Checks

Always add safety checks before flight:

battery = drone.get_battery()
if battery > 30:
    drone.takeoff()
    # Your flight code
    drone.land()
else:
    print("Battery too low!")

4 Using Sensors

Sensors help your drone understand its environment:

Front range sensor: Measures distance to obstacles
Color sensor: Detects colors
Gyroscope: Measures rotation

distance = drone.get_front_range()
if distance < 50:
    print("Obstacle detected!")
