) const
virtual

Given a set of joint angles and a set of links, compute their pose.

This FK routine is only used if 'use_plugin_fk' is set in the 'arm_kinematics_constraint_aware' node, otherwise ROS TF is used to calculate the forward kinematics

Parameters
link_namesA set of links for which FK needs to be computed
joint_anglesThe state for which FK is being computed
posesThe resultant set of poses (in the frame returned by getBaseFrame())
Returns
True if a valid solution was found, false otherwise

Implements kinematics::KinematicsBase.

) const
virtual

Given a set of joint angles and a set of links, compute their pose.

Parameters
link_namesA set of links for which FK needs to be computed
joint_anglesThe state for which FK is being computed
posesThe resultant set of poses (in the frame returned by getBaseFrame())
Returns
True if a valid solution was found, false otherwise

Given a desired pose of the end-effector, compute the joint angles to reach it.

const std::vector< double > &  ik_seed_state,
std::vector< std::vector< double >> &  solutions,
kinematics::KinematicsResult result,
const kinematics::KinematicsQueryOptions options 
) const

Given a desired pose of the end-effector, compute the set joint angles solutions that are able to reach it.

This is a default implementation that returns only one solution and so its result is equivalent to calling 'getPositionIK(...)' with a zero initialized seed.

Parameters
ik_posesThe desired pose of each tip link
ik_seed_statean initial guess solution for the inverse kinematics
solutionsA vector of vectors where each entry is a valid joint solution
resultA struct that reports the results of the query
optionsAn option struct which contains the type of redundancy discretization used. This default implementation only supports the KinmaticSearches::NO_DISCRETIZATION method; requesting any other will result in failure.
Returns
True if a valid set of solutions was found, false otherwise.

bool ikfast_kinematics_plugin::IKFastKinematicsPlugin::setRedundantJoints ( const std::vector< unsigned int > &  redundant_joint_indices)
virtual

Overrides the default method to prevent changing the redundant joints.

Reimplemented from kinematics::KinematicsBase.

void ikfast_kinematics_plugin::IKFastKinematicsPlugin::setSearchDiscretization ( const std::map< int, double > &  discretization)

Sets the discretization value for the redundant joint.

Since this ikfast implementation allows for one redundant joint then only the first entry will be in the discretization map will be used. Calling this method replaces previous discretization settings.

Parameters
discretizationa map of joint indices and discretization value pairs.
