Sensor Data Interpretation Output

What is the output of this code that simulates sensor data readings for obstacle distance and drone speed?

Drone Programming

def sensor_readings():
    distance = 15  # meters
    speed = 5      # m/s
    if distance < 10:
        status = 'Obstacle too close'
    elif speed > 10:
        status = 'Speed too high'
    else:
        status = 'All clear'
    return status

print(sensor_readings())

A All clear

B Speed too high

C Obstacle too close

D None

💡 Hint

Check the conditions for distance and speed in the code.

The distance is 15 which is not less than 10, and speed is 5 which is not greater than 10, so the else block runs returning 'All clear'.

Why Sensors Are Critical for Situational Awareness

Which of the following best explains why sensors provide situational awareness for drones?

A Sensors collect real-time data about the environment, allowing the drone to react to changes.

B Sensors store flight plans for the drone to follow without changes.

C Sensors increase the drone's battery life by reducing power consumption.

D Sensors allow the drone to communicate with other drones only.

💡 Hint

Think about what situational awareness means in real life.

Situational awareness means knowing what is happening around you. Sensors provide real-time data so the drone can understand and react to its environment.

Identify the Error in Sensor Data Processing

What error does this code raise when processing sensor data?

Drone Programming

sensor_values = {'distance': 20, 'speed': 8}

if sensor_values['distance'] < 15:
    alert = 'Too close'
elif sensor_values['speed'] > 10:
    alert = 'Speeding'
else:
    alert = 'Safe'

print(alert)

A No error, output is 'Safe'

B KeyError because 'speed' key is missing

C TypeError because comparison is invalid

D SyntaxError due to missing colon after elif condition

💡 Hint

Check the syntax of the if-elif statements carefully.

The elif line is missing a colon at the end, causing a SyntaxError.

Output of Sensor Fusion Algorithm

What is the output of this code that fuses two sensor readings to decide drone action?

Drone Programming

def fuse_sensors(distance, light):
    if distance < 10 and light < 50:
        return 'Hover'
    elif distance >= 10 and light >= 50:
        return 'Move Forward'
    else:
        return 'Caution'

print(fuse_sensors(8, 60))

A Hover

B None

C Caution

D Move Forward

💡 Hint

Check both conditions carefully for distance and light.

Distance is 8 (less than 10) but light is 60 (not less than 50), so neither first nor second condition matches, so else returns 'Caution'.

Number of Sensor Alerts Generated

Given this code that processes a list of sensor distances, how many alerts will be generated for distances less than 5 meters?

Drone Programming

distances = [3, 7, 2, 10, 4, 6]
alerts = [d for d in distances if d < 5]
print(len(alerts))

A 4

B 3

C 2

D 5

💡 Hint

Count how many numbers in the list are less than 5.

The distances less than 5 are 3, 2, and 4, so 3 alerts are generated.
