Detailed Description

Base class for a mode.

Member Function Documentation

checkArmingAndRunConditions()

virtual void px4_ros2::ModeBase::checkArmingAndRunConditions ( HealthAndArmingCheckReporter &  reporter )

inlinevirtual

Report any custom mode requirements. This is called regularly, also while the mode is active.

completed()

void px4_ros2::ModeBase::completed

(

Result

result

)

Mode completed signal. Call this when the mode is finished. A mode might never call this, but modes like RTL, Land or Takeoff are expected to signal their completion.

Parameters

result

doRegister()

bool px4_ros2::ModeBase::doRegister

(

)

Register the mode. Call this once on startup, unless there's an associated executor. This is a blocking method.

Returns

true on success

modeRequirements()

RequirementFlags& px4_ros2::ModeBase::modeRequirements ( )

inline

Get / modify mode requirements. These are generally automatically set based on selected setpoint types, and are used to prevent arming or trigger failsafes.

onActivate()

virtual void px4_ros2::ModeBase::onActivate ( )

pure virtual

Called whenever the mode is activated, also if the vehicle is disarmed

onDeactivate()

virtual void px4_ros2::ModeBase::onDeactivate ( )

pure virtual

Called whenever the mode is deactivated, also if the vehicle is disarmed

setSetpointUpdateRate()

void px4_ros2::ModeBase::setSetpointUpdateRate

(

float

rate_hz

)

Set the update rate when the mode is active. This is set automatically from the configured setpoints, but can be set as needed.

Parameters

rate_hz

set to 0 to disable
