Why sensors provide situational awareness in Drone Programming - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to read the sensor value.

Drone Programming

sensor_value = sensor.[1]()

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

Aread

Bwrite

Cconnect

Dstart

💡 Hint

Common Mistakes

Using 'write' instead of 'read' will try to send data, not get it.

The read() method gets the current value from the sensor, which is essential for situational awareness.

medium

Complete the code to check if the sensor detects an obstacle.

Drone Programming

if sensor.[1]() < 10:
    alert('Obstacle nearby!')

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

Adistance

Bget_distance

Cmeasure

Ddetect

💡 Hint

Common Mistakes

Using 'distance' alone is not a method call.

The get_distance() method returns the distance to the nearest object, which helps the drone avoid collisions.

3fill in blank

hard

Fix the error in the code to update sensor data correctly.

Drone Programming

sensor_data = sensor.[1]

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

Arefresh

Bupdate

Crefresh()

Dupdate()

💡 Hint

Common Mistakes

Forgetting parentheses means the method is not called, just referenced.

The update() method must be called with parentheses to execute and get fresh sensor data.

4fill in blank

hard

Fill both blanks to create a dictionary of sensor readings above a threshold.

Drone Programming

important_readings = {sensor.[1](): sensor.[2]() for _ in range(5) if sensor.[1]() > 50}

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

Aget_temperature

Bget_humidity

Cget_pressure

Dget_light

Attempts:

3 left

💡 Hint

Common Mistakes

Using the same method for both blanks will cause incorrect data pairing.

This code collects temperature and humidity readings from the sensor when the temperature is above 50.

5fill in blank

hard

Fill all three blanks to filter sensor data and create a summary dictionary.

Drone Programming

summary = {sensor.[1](): sensor.[2]() for _ in range(10) if sensor.[3]() < 20}

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

Aget_light

Bget_temperature

Cget_distance

Dget_humidity

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing up the methods will cause wrong filtering or data collection.

This code collects light and temperature readings only when the distance detected is less than 20.
