Btake_off

Chover

Dmove_forward

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'land' instead of 'take_off' will make the drone land.

The take_off() method makes the drone lift off the ground.

Complete the code to make the drone fly forward by 10 meters.

Drone Programming

drone.move_forward([1])

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

A10

B5

C15

D20

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing a smaller or larger number will move the drone the wrong distance.

Passing 10 makes the drone move forward 10 meters.

hard

Fix the error in the code to check if the drone's battery is above 20%.

Drone Programming

if drone.battery_level [1] 20:

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

A<

B<=

C>

D==

Attempts:

💡 Hint

Common Mistakes

Using '<' will check if battery is less than 20, which is wrong here.

The '>' operator checks if battery level is greater than 20%.

4fill in blank

hard

Fill both blanks to create a dictionary of drone sensors with their status.

Drone Programming

sensors_status = {"camera": [1], "gps": [2]

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

ATrue

BFalse

C"active"

D"inactive"

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing up True/False or using strings instead of booleans.

The camera is active (True) and GPS is inactive ("inactive") in this example.

5fill in blank

hard

Fill all three blanks to filter drone data for sensors with values above 50.

Drone Programming

filtered_data = {k: v for k, v in drone_data.items() if v [1] [2] and k [3] "temperature"}

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

A>

B50

C!=

D==

Attempts:

3 left

💡 Hint

Common Mistakes

Using '==' instead of '!=' will only keep temperature sensor.

This code keeps sensors with values greater than 50 and excludes the temperature sensor.

Practice

1. Why are drones useful in industries like agriculture and construction?

easy

A. They can reach hard-to-access places quickly and safely.

B. They replace all human workers completely.

C. They only work indoors and need constant supervision.

D. They are very slow and expensive to operate.

Solution

1. Step 1: Understand drone capabilities

   Drones can fly and reach places that are difficult or dangerous for people to access.

2. Step 2: Compare options

   Options A, B, and C are incorrect because drones do not replace all workers, can work outdoors, and are designed to be efficient.

3. Final Answer:

   They can reach hard-to-access places quickly and safely. -> Option A

4. Quick Check:

   Drones reach tough spots = D [OK]

Hint: Think about where humans struggle to go safely [OK]

Common Mistakes:

• Thinking drones replace all human jobs
• Assuming drones only work indoors
• Believing drones are slow and costly

2. Which of the following is the correct way to command a drone to take off in a simple drone programming language?

easy

A. takeoff()

B. fly.takeoff

C. start_fly()

D. drone fly()

Solution

1. Step 1: Identify correct function syntax

   In most simple drone programming languages, commands are functions with parentheses, like takeoff().

2. Step 2: Check other options

   Options A, B, and D are incorrect because they either miss parentheses or use wrong syntax.

3. Final Answer:

   takeoff() -> Option A

4. Quick Check:

   Function call syntax = takeoff() [OK]

Hint: Look for function calls with parentheses [OK]

Common Mistakes:

• Missing parentheses in function calls
• Using incorrect command names
• Combining words without proper syntax

3. What will the following drone program output if it prints the drone's altitude after commands?

drone.takeoff()
drone.ascend(10)
print(drone.altitude)

medium

A. 0

B. Error

C. 1

D. 10

Solution

1. Step 1: Understand the commands

   drone.takeoff() makes the drone lift off, setting altitude to 0. drone.ascend(10) raises it by 10 units to 10.

2. Step 2: Calculate final altitude

   takeoff() sets altitude to 0, ascend(10) adds 10 for final altitude of 10.

3. Final Answer:

   10 -> Option D

4. Quick Check:

   Altitude after ascend(10) = 10 [OK]

Hint: Add ascend value to current altitude [OK]

Common Mistakes:

• Thinking altitude stays 0 after takeoff
• Thinking takeoff sets altitude to 1 only
• Expecting an error from print

4. Find the error in this drone program snippet:

drone.takeoff()
drone.ascend(5)
drone.ascend(-3)
print(drone.altitude)

medium

A. Missing parentheses in takeoff command.

B. No error; program runs and prints altitude 2.

C. Print statement syntax is wrong.

D. Negative ascend value is invalid and causes error.

Solution

1. Step 1: Check each command

   takeoff() lifts drone to altitude 0, ascend(5) adds 5 (total 5), ascend(-3) subtracts 3 (total 2).

2. Step 2: Verify print and syntax

   All commands have correct syntax; negative ascend reduces altitude, which is allowed.

3. Final Answer:

   No error; program runs and prints altitude 2. -> Option B

4. Quick Check:

   Negative ascend allowed = altitude 2 [OK]

Hint: Negative ascend changes altitude down, not error [OK]

Common Mistakes:

• Thinking negative ascend causes error
• Missing parentheses in commands
• Assuming print syntax is wrong

5. You want a drone to survey a large farm by flying over 5 points and collecting data at each. Which programming approach best solves this efficiently?

hard

A. Fly randomly and hope to cover all points.

B. Write separate commands for each point manually.

C. Use a loop to fly to each point and collect data automatically.

D. Only collect data at the first point to save time.

Solution

1. Step 1: Understand the problem

   Surveying multiple points requires repeating similar actions for each point.

2. Step 2: Choose efficient programming method

   Using a loop automates flying and data collection at each point, saving time and reducing errors.

3. Final Answer:

   Use a loop to fly to each point and collect data automatically. -> Option C

4. Quick Check:

   Loop automates repeated tasks = A [OK]

Hint: Loops repeat tasks efficiently [OK]

Common Mistakes:

• Writing repetitive manual commands
• Flying randomly without control
• Skipping data collection points
