Formation flying basics in Drone Programming - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to set the leader drone's speed to 5 meters per second.

Drone Programming

💡 Hint

Common Mistakes

Using zero speed which stops the drone.

Setting speed too high causing instability.

The leader drone's speed is set to 5 m/s to maintain a steady pace for the formation.

2fill in blank

medium

Complete the code to make the follower drone maintain a distance of 3 meters behind the leader.

Drone Programming

follower_drone.set_follow_distance([1])

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

💡 Hint

Common Mistakes

Setting distance to zero causing collision risk.

Using a distance larger than leader speed.

The follower drone keeps 3 meters behind the leader to maintain safe formation spacing.

3fill in blank

hard

Fix the error in the code to correctly update the formation position of the follower drone.

Drone Programming

follower_drone.update_position(leader_drone.position [1] follower_drone.offset)

💡 Hint

Common Mistakes

Adding offset causing follower to move ahead.

Multiplying or dividing positions causing errors.

The follower drone's position is the leader's position minus the offset to stay behind.

4fill in blank

hard

Fill both blanks to create a dictionary mapping each drone's ID to its current altitude if altitude is above 10 meters.

Drone Programming

altitudes = {drone.id: drone.[1] for drone in drones if drone.[1] [2] 10}

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

💡 Hint

Common Mistakes

Using speed instead of altitude.

Using '<' which filters drones below 10 meters.

We use 'altitude' to get the drone's height and filter drones flying above 10 meters using '>'.

5fill in blank

hard

Fill all three blanks to create a dictionary of drone IDs with their speeds if speed is less than 8 m/s.

Drone Programming

slow_drones = {drone.[1]: drone.[2] for drone in drones if drone.[2] [3] 8}

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

💡 Hint

Common Mistakes

Using altitude instead of speed.

Using '>' which filters faster drones.

The dictionary maps drone IDs to their speeds, filtering drones moving slower than 8 m/s.
