	)		const

virtual

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

Parameters

link_names	A set of links for which FK needs to be computed
joint_angles	The state for which FK is being computed
poses	The resultant set of poses (in the frame returned by getBaseFrame())

Returns: True if a valid solution was found, false otherwise

	)		const

virtual

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

Parameters

ik_pose	the desired pose of the link
ik_seed_state	an initial guess solution for the inverse kinematics
solution	the solution vector
error_code	an error code that encodes the reason for failure or success

Returns: True if a valid solution was found, false otherwise

		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_poses	The desired pose of each tip link
ik_seed_state	an initial guess solution for the inverse kinematics
solutions	A vector of vectors where each entry is a valid joint solution
result	A struct that reports the results of the query
options	An 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.
