Output of waypoint navigation sequence

Consider a drone programmed to follow waypoints in sequence. What will be the output of the following code simulating the drone's position updates?

Drone Programming

waypoints = [(0,0), (10,0), (10,10), (0,10)]
position = (0,0)
for wp in waypoints:
    position = wp
    print(f"Drone reached waypoint at {position}")

A Drone reached waypoint at (0, 0)\nDrone reached waypoint at (0, 0)\nDrone reached waypoint at (0, 0)\nDrone reached waypoint at (0, 0)

B Drone reached waypoint at (0, 0)\nDrone reached waypoint at (10, 0)\nDrone reached waypoint at (10, 10)\nDrone reached waypoint at (0, 10)

C Drone reached waypoint at (10, 10)\nDrone reached waypoint at (10, 10)\nDrone reached waypoint at (10, 10)\nDrone reached waypoint at (10, 10)

D Drone reached waypoint at (0, 0)\nDrone reached waypoint at (10, 10)\nDrone reached waypoint at (0, 10)\nDrone reached waypoint at (10, 0)

💡 Hint

Think about how the loop updates the position variable and prints it each time.

The loop updates the drone's position to each waypoint in order and prints the current position. So the output shows the drone reaching each waypoint in sequence.

Why waypoint navigation enables autonomy

Why does using waypoint navigation allow a drone to perform autonomous missions?

A Because the drone can follow a predefined path without human control once waypoints are set

B Because the drone requires constant manual control to reach each waypoint

C Because waypoints allow the drone to avoid obstacles automatically without any programming

D Because waypoints make the drone fly randomly to explore the area

💡 Hint

Think about what autonomy means for a drone mission.

Waypoint navigation lets the drone follow a set path by itself, so it can complete missions without a pilot controlling it all the time.

Identify the error in waypoint navigation code

This code is intended to move a drone through waypoints, but it raises an error. What is the error?

Drone Programming

waypoints = [(0,0), (5,5), (10,10)]
for i in range(len(waypoints)):
    print(f"Moving to waypoint {i+1}: {waypoints[i]}")
    drone.move_to(waypoints[i])
    drone.wait_until_arrived()

# drone object is not defined

A SyntaxError due to missing colon in for loop

B IndexError because the loop goes out of range

C NameError because 'drone' is not defined

D TypeError because waypoints is not iterable

💡 Hint

Check if all variables and objects are defined before use.

The code tries to call methods on 'drone' but no drone object is created or imported, causing a NameError.

📝 Syntax

Correct syntax for waypoint list comprehension

Which option correctly creates a list of waypoints with x and y coordinates from 0 to 4?

A waypoints = [(x, y) for x range(5) for y range(5)]

B waypoints = [(x, y) in range(5) for x in range(5)]

C waypoints = [(x, y) for x in range(5), y in range(5)]

D waypoints = [(x, y) for x in range(5) for y in range(5)]

💡 Hint

Remember the syntax for nested loops in list comprehensions.

Option D uses the correct syntax for nested loops in a list comprehension to generate all (x,y) pairs.

🚀 Application

Calculate total distance for waypoint mission

Given the waypoints [(0,0), (3,4), (6,8)], what is the total distance the drone will travel following them in order? Use Euclidean distance between points.

A 10.0

B 12.0

C 20.0

D 15.0

💡 Hint

Calculate distance between each pair: sqrt((x2-x1)^2 + (y2-y1)^2) and sum them.

Distance from (0,0) to (3,4) is sqrt(9+16)=5, from (3,4) to (6,8) is sqrt(9+16)=5, total 10.0.
