Search and rescue assistance in Drone Programming - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

Complete the code to start the drone's search mode.

💡 Hint

Common Mistakes

Using 'land' instead of 'takeoff' will stop the drone immediately.

The takeoff() command makes the drone start flying and begin the search.

2fill in blank

medium

Complete the code to check if the drone has found a person.

Drone Programming

if drone.detect_person() [1] True:

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

D>

💡 Hint

Common Mistakes

Using '!=' will check for no detection, which is wrong here.

The condition == True checks if the drone detected a person.

3fill in blank

Fix the error in the code to send a rescue signal when a person is found.

Drone Programming

if drone.detect_person() == True:
    drone.[1]('rescue_signal')

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

💡 Hint

Common Mistakes

Using 'receive' or 'wait' will not send the signal.

The send() method is used to send signals like 'rescue_signal'.

4fill in blank

hard

Fill both blanks to create a dictionary of detected persons with their distances.

Drone Programming

detected = {person: drone.[1](person) for person in drone.[2]()}

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

Adistance_to

Baltitude

Cdetected_persons

Dbattery_level

Attempts:

💡 Hint

Common Mistakes

Using 'altitude' or 'battery_level' will not give correct distances or persons.

The drone calculates distance with distance_to() for each person in detected_persons().

5fill in blank

hard

Fill all three blanks to filter persons within 100 meters and prepare rescue messages.

Drone Programming

close_persons = {person: dist for person, dist in detected.items() if dist [1] 100}
messages = [f"Rescue needed for [2] at [3] meters" for person, dist in close_persons.items()]

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

A<

Bperson

Cdist

D>

Attempts:

3 left

💡 Hint

Common Mistakes

Using '>' will select persons farther than 100 meters, which is wrong.

We select persons with distance less than 100 (<), then use person and dist to create messages.
