Why simulation prevents costly crashes in Drone Programming - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to start the drone simulation.

Bstop

Cstart

Dpause

Attempts:

💡 Hint

Common Mistakes

Using 'launch' instead of 'start' causes an error because 'launch' is not defined.

The start() method begins the drone simulation, allowing you to test flight without risk.

Complete the code to check if the drone has crashed in simulation.

Drone Programming

if drone.[1] == True:
    print('Crash detected!')

💡 Hint

Common Mistakes

Checking 'is_flying' will not detect crashes.

The has_crashed property tells if the drone crashed during simulation.

Fix the error in the code to safely land the drone after simulation.

💡 Hint

Common Mistakes

Using 'takeoff' or 'fly' will cause errors or unsafe behavior.

The land() method safely lands the drone to avoid crashes.

4fill in blank

hard

Fill both blanks to create a dictionary of drone status with battery and altitude.

Drone Programming

status = {'battery': drone.[1], 'altitude': drone.[2]

Drag options to blanks, or click blank then click option'

Abattery_level

Baltitude_meters

Cbattery_percentage

Daltitude_feet

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'battery_level' or 'altitude_feet' may not match the drone API.

battery_percentage gives battery status, and altitude_meters gives altitude in meters.

5fill in blank

hard

Fill all three blanks to filter sensor data for values above threshold.

Drone Programming

filtered = {sensor: value for sensor, value in data.items() if value [1] threshold and sensor [2] 'temp' and value [3] 0}

Drag options to blanks, or click blank then click option'

A>

B!=

C>=

D<

💡 Hint

Common Mistakes

Using wrong comparison operators causes wrong filtering or errors.

We filter values less than threshold (<), sensors not equal to 'temp' (!=), and values greater or equal to zero (>=).
