Member Function Documentation

◆ addToGUI()

void mc_tasks::OrientationTask::addToGUI ( mc_rtc::gui::StateBuilder & )

overrideprotectedvirtual

Add elements to the GUI through the helper

This will be called by the solver when the task is added.

The default implementation adds the type of the task under the {"Tasks", name_} category.

Reimplemented from mc_tasks::MetaTask.

◆ addToLogger()

void mc_tasks::OrientationTask::addToLogger ( mc_rtc::Logger & )

overridevirtual

Add entries to the logger

This will be called by the solver if it holds a valid logger instance when the task is added.

The default implementation adds nothing to the log.

Reimplemented from mc_tasks::MetaTask.

◆ orientation() [1/2]

Eigen::Matrix3d mc_tasks::OrientationTask::orientation ( )

Get the current frame orientation target.

Returns: The body orientation target in world frame

◆ orientation() [2/2]

void mc_tasks::OrientationTask::orientation ( const Eigen::Matrix3d & ori )

Set the frame orientation target.

Parameters

ori	Body orientation in world frame

◆ reset()

void mc_tasks::OrientationTask::reset ( )

overridevirtual

Reset the task.

Set the task objective to the current frame orientation

Implements mc_tasks::MetaTask.
