Member Function Documentation

refFrame()

const std::string & wbc::SpatialAccelerationTask::refFrame ( )

inline

Returns the reference frame. This is the frame in which the task reference is assumed to be given. In this case the given reference acceleration will be transformed from this frame to world frame.

setReference()

void wbc::SpatialAccelerationTask::setReference

(

const types::SpatialAcceleration &

ref

)

Update the Cartesian reference input for this task.

Parameters

ref	Reference input for this task. Only the acceleration part is relevant (Must have a valid linear and angular acceleration!)

tipFrame()

const std::string & wbc::SpatialAccelerationTask::tipFrame ( )

inline

Returns the tip frame. This is the tip of kinematic chain used by the task.

update()

void wbc::SpatialAccelerationTask::update ( )

overridevirtual

Compute the cartesian task matrix A.

Parameters

robot_model

Pointer to the robot model from which get the state and compute the cartesian task matrix A

Implements wbc::Task.
