 Given a desired pose of the end-effector, search for the joint angles required to reach it. This particular method is intended for "searching" for a solutions by stepping through the redundancy (or other numerical routines). The consistency_limit specifies that only certain redundancy positions around those specified in the seed state are admissible and need to be searched.

const std::vector< double > &  joint_angles,
std::vector< geometry_msgs::Pose > &  poses 
) 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.

bool  lock_redundant_joints = false 
) const

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

Parameters:
ik_posethe desired pose of the link
ik_seed_statean initial guess solution for the inverse kinematics
solutionthe solution vector
error_codean error code that encodes the reason for failure or success
lock_redundant_joints?
