Battery failsafe in Drone Programming - Mini Project: Build & Apply

Battery failsafe

📖 Scenario: You are programming a drone to monitor its battery level during flight. To keep the drone safe, it must automatically land when the battery level gets too low.

🎯 Goal: Build a simple battery failsafe system that checks the drone's battery level and decides when to land.

📋 What You'll Learn

Create a variable to store the current battery level as a percentage.

Create a variable for the battery low threshold percentage.

Write a condition to check if the battery level is below the threshold.

Print a message to land the drone if battery is low, otherwise print that flight continues.

💡 Why This Matters

🌍 Real World

Drones need to monitor battery levels to avoid crashes and damage by landing safely when power is low.

💼 Career

Understanding battery failsafe logic is important for drone software developers and engineers working on autonomous systems.

1

Set the battery level

Create a variable called battery_level and set it to 35 to represent the current battery percentage.

Drone Programming

# Create a variable called battery_level and set it to 35
# Your code here

Need a hint?

Use a simple assignment like battery_level = 35.

2

Set the low battery threshold

Create a variable called low_battery_threshold and set it to 30 to represent the battery percentage that triggers landing.

Drone Programming

battery_level = 35
# Create a variable called low_battery_threshold and set it to 30
# Your code here

Need a hint?

Use a simple assignment like low_battery_threshold = 30.

3

Check battery level and decide

Write an if statement that checks if battery_level is less than low_battery_threshold. If true, set a variable action to "Land the drone". Otherwise, set action to "Continue flight".

Drone Programming

battery_level = 35
low_battery_threshold = 30
# Write an if statement to set action based on battery level
# Your code here

Need a hint?

Use if battery_level < low_battery_threshold: and set action accordingly.

4

Display the action

Write a print statement to display the value of the variable action.

Drone Programming

battery_level = 35
low_battery_threshold = 30
if battery_level < low_battery_threshold:
    action = "Land the drone"
else:
    action = "Continue flight"
# Print the action
# Your code here

Need a hint?

Use print(action) to show the decision.
