Why waypoint navigation enables autonomous missions in Drone Programming - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a waypoint with latitude.

Drone Programming

waypoint = {'latitude': [1], 'longitude': -122.084}

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

A37.422

B'37.422'

Clatitude

Dlongitude

💡 Hint

Common Mistakes

Using quotes around the number, making it a string instead of a number.

The latitude value must be a number, not a string or variable name.

2fill in blank

medium

Complete the code to add a waypoint to the mission list.

Drone Programming

mission = []
mission.append([1])

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

B{'latitude': 37.422, 'longitude': -122.084}

Cmission

Dwaypoint

💡 Hint

Common Mistakes

Appending a variable name that is not defined.

You need to append a dictionary representing the waypoint, not a variable name.

3fill in blank

hard

Fix the error in the code to loop through waypoints correctly.

Drone Programming

for [1] in mission:
    print(f"Flying to {waypoint['latitude']}, {waypoint['longitude']}")

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

Bmission

Cwaypoint

Dpoint

💡 Hint

Common Mistakes

Using 'mission' as loop variable, which is the list, not an item.

The loop variable should be 'waypoint' to match the print statement.

4fill in blank

hard

Fill both blanks to check if the drone reached the waypoint.

Drone Programming

if current_location['latitude'] [1] waypoint['latitude'] and current_location['longitude'] [2] waypoint['longitude']:
    print('Waypoint reached')

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

B>

C<

D!=

💡 Hint

Common Mistakes

Using greater than or less than operators which do not confirm exact location.

We check if both latitude and longitude match exactly to confirm reaching the waypoint.

5fill in blank

hard

Fill both blanks to create a dictionary comprehension for waypoints above altitude 100.

Drone Programming

high_altitude_waypoints = {wp['name']: wp['altitude'] for wp in waypoints if wp['altitude'] [1] [2]

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

A>

B100

C<

D==

Attempts:

3 left

💡 Hint

Common Mistakes

Using '<' or '==' which do not select waypoints above 100.

The comprehension filters waypoints with altitude greater than 100.
