Failsafe actions (RTL, Land, SmartRTL) in Drone Programming - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to set the drone's failsafe action to Return To Launch (RTL).

Drone Programming

drone.setFailsafeAction([1])

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

AFailsafeAction.SMART_RTL

BFailsafeAction.LAND

DFailsafeAction.HOVER

💡 Hint

Common Mistakes

Choosing LAND instead of RTL will make the drone land immediately instead of returning.

SMART_RTL is a different mode that may not be supported everywhere.

The correct failsafe action to make the drone return to its launch point is FailsafeAction.RTL.

Complete the code to make the drone land immediately as a failsafe action.

Drone Programming

drone.setFailsafeAction([1])

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

AFailsafeAction.LAND

BFailsafeAction.HOVER

💡 Hint

Common Mistakes

Using RTL will make the drone fly back instead of landing.

SMART_RTL is a smarter return mode, not immediate landing.

To make the drone land immediately on failsafe, use FailsafeAction.LAND.

hard

Fix the error in the code to set the failsafe action to Smart Return To Launch (SmartRTL).

Drone Programming

drone.setFailsafeAction([1])

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

AFailsafeAction.SMART_RTL

BFailsafeAction.LAND

CFailsafeAction.RTL

DFailsafeAction.HOVER

💡 Hint

Common Mistakes

Using RTL instead of SMART_RTL misses the smart features.

LAND will cause the drone to land immediately, not return.

The correct constant for Smart Return To Launch is FailsafeAction.SMART_RTL.

Fill both blanks to check if the failsafe action is set to RTL or Land.

Drone Programming

if drone.getFailsafeAction() == [1] or drone.getFailsafeAction() == [2]:
    drone.alertPilot()

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

💡 Hint

Common Mistakes

Checking for SMART_RTL instead of RTL or LAND.

Using HOVER which is not a failsafe action here.

This code checks if the failsafe action is either RTL or LAND, then alerts the pilot.

5fill in blank

hard

Fill all three blanks to create a dictionary mapping failsafe actions to their descriptions.

Drone Programming

failsafe_descriptions = {
    [1]: "Return To Launch",
    [2]: "Land Immediately",
    [3]: "Smart Return To Launch"
}

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

AFailsafeAction.RTL

BFailsafeAction.LAND

CFailsafeAction.SMART_RTL

DFailsafeAction.HOVER

💡 Hint

Common Mistakes

Mixing up the constants and descriptions.

Including HOVER which is not part of the failsafe descriptions here.

This dictionary links each failsafe action constant to a clear description string.
