Collision avoidance in swarms in Drone Programming - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to check if two drones are too close.

Drone Programming

if distance(drone1.position, drone2.position) [1] safe_distance:
    avoid_collision()

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

💡 Hint

Common Mistakes

Using greater than instead of less than.

Checking for equality only.

We check if the distance is less than the safe distance to avoid collisions.

2fill in blank

medium

Complete the code to update drone velocity to avoid collision.

Drone Programming

if distance(drone.position, neighbor.position) < safe_distance:
    drone.velocity = drone.velocity [1] avoid_vector

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

💡 Hint

Common Mistakes

Adding the avoid vector instead of subtracting.

Multiplying velocity by avoid vector.

We subtract the avoid vector to steer the drone away from neighbors.

hard

Fix the error in the collision check condition.

Drone Programming

if distance(drone.position, neighbor.position) [1] safe_distance:
    slow_down()

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

A<=

B<

D>=

💡 Hint

Common Mistakes

Using '>=' which checks the wrong condition.

Using '<' without equality.

The operator '<=' correctly checks if the distance is less than or equal to the safe distance.

4fill in blank

hard

Fill both blanks to create a dictionary of drones with their speeds above threshold.

Drone Programming

fast_drones = {drone.id: drone.[1] for drone in swarm if drone.[2] > speed_threshold}

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

💡 Hint

Common Mistakes

Using 'velocity' which is a vector, not a speed value.

Using 'altitude' which is unrelated.

We use 'speed' to get the drone's speed and filter drones with speed above the threshold.

5fill in blank

hard

Fill all three blanks to filter drones and create a dictionary with adjusted speeds.

Drone Programming

adjusted_speeds = {drone.[1]: drone.[2] * speed_factor for drone in swarm if drone.[3] < max_speed}

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

💡 Hint

Common Mistakes

Using 'altitude' instead of 'speed'.

Mixing keys and values incorrectly.

We use 'id' as the key, multiply 'speed' by a factor, and filter drones with speed less than max_speed.
