Detailed Description

A grasp is mainly specified by a TCP to object transformation.

Constructor & Destructor Documentation

Constructor

Parameters
nameThe name of this grasp.
robotTypeThe robot type for which this grasp is defined.
eefThe end effector name.
poseInTCPCoordSystemThe pose of the object, given in eef's tcp coordinate system
creationA custom string explaining how the grasp was created.

Member Function Documentation

VirtualRobot::GraspPtr VirtualRobot::Grasp::clone ( )
std::map< std::string, float > VirtualRobot::Grasp::getConfiguration ( )

Returns the (optionally) stored configuration of the fingers / actors.

std::string VirtualRobot::Grasp::getCreationMethod ( )
std::string VirtualRobot::Grasp::getEefName ( )
std::string VirtualRobot::Grasp::getName ( )
Eigen::Matrix4f VirtualRobot::Grasp::getObjectTargetPoseGlobal ( const Eigen::Matrix4f &  graspingPose)

The returned pose is the object pose that have to be set in order to apply a grasp at pose graspingPose.

std::string VirtualRobot::Grasp::getPreshapeName ( )
float VirtualRobot::Grasp::getQuality ( )
std::string VirtualRobot::Grasp::getRobotType ( )
Eigen::Matrix4f VirtualRobot::Grasp::getTargetPoseGlobal ( RobotPtr  robot)

Get the (current) global pose of the target object when the grasp is applied on the corresponding EEF of robot. Note, that this pose is only valid for the current configuration of the robot. When the robot moves, the grasping pose will change, and you have to call this method again.

Eigen::Matrix4f VirtualRobot::Grasp::getTcpPoseGlobal ( const Eigen::Matrix4f &  objectPose)

Get the global pose that has to be achieved by the tcp in order to apply the grasp on the object at position objectPose.

Eigen::Matrix4f VirtualRobot::Grasp::getTransformation ( )

Return the transformation of this grasp. The transformation is given in the coordinate system of the tcp (whereas the tcp belongs to the eef). This transformation specifies the tcp to object relation.

void VirtualRobot::Grasp::print ( bool  printDecoration = true)
void VirtualRobot::Grasp::setConfiguration ( std::map< std::string, float > &  c)

Optionally the configuration of the fingers / actors can be stored.

void VirtualRobot::Grasp::setName ( const std::string &  name)
void VirtualRobot::Grasp::setPreshape ( const std::string &  preshapeName)
void VirtualRobot::Grasp::setQuality ( float  q)
void VirtualRobot::Grasp::setTransformation ( const Eigen::Matrix4f &  tcp2Object)

Set the transformation of this grasp. The transformation is given in the coordinate system of the tcp (whereas the tcp belongs to the eef).

Parameters
tcp2ObjectThe transformation specifies the tcp to object relation.
std::string VirtualRobot::Grasp::toXML ( int  tabs = 2)
