Receiving telemetry data in Drone Programming - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to receive telemetry data from the drone.

Drone Programming

telemetry = drone.[1]()

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

💡 Hint

Common Mistakes

Using 'send_command' instead of 'get_telemetry'.

Trying to use 'connect' to receive data.

The get_telemetry() method is used to receive telemetry data from the drone.

2fill in blank

medium

Complete the code to extract the drone's altitude from the telemetry data.

Drone Programming

altitude = telemetry.[1]['altitude']

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

💡 Hint

Common Mistakes

Using 'send' or 'receive' instead of 'data'.

Trying to access 'status' which is not the telemetry dictionary.

The telemetry data is stored in the data attribute, which is a dictionary containing keys like 'altitude'.

3fill in blank

hard

Fix the error in the code to correctly print the drone's battery level from telemetry.

Drone Programming

print('Battery level:', telemetry.[1]['battery'])

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

Cstatus

Dbattery_level

💡 Hint

Common Mistakes

Trying to access 'battery' directly on telemetry.

Using 'battery_level' which is not an attribute.

The telemetry dictionary is accessed via the data attribute, which contains the 'battery' key.

4fill in blank

hard

Fill both blanks to create a dictionary of altitude and speed from telemetry data.

Drone Programming

info = {'altitude': telemetry.[1]['altitude'], 'speed': telemetry.[2]['speed']}

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

Adata

Bstatus

Cinfo

Dmetrics

💡 Hint

Common Mistakes

Using different attributes for altitude and speed.

Using 'status' or 'info' which do not hold telemetry data.

Both 'altitude' and 'speed' are keys inside the telemetry's data dictionary.

5fill in blank

hard

Fill all three blanks to filter telemetry data for altitude above 100 and speed below 50.

Drone Programming

filtered = {k: v for k, v in telemetry.[1].items() if telemetry.[1]['altitude'] [2] 100 and telemetry.[1]['speed'] [3] 50}

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

💡 Hint

Common Mistakes

Using 'status' instead of 'data'.

Mixing up comparison operators.

The telemetry data is in data. We filter where altitude is greater than 100 and speed is less than 50.
