Given the name of an object existing in the planning scene, attach it to a link. The link used is specified by the second argument. If left unspecified, the end-effector link is used, if one is known. If there is no end-effector link, the first link in the group is used. If no link is identified, failure is reported. True is returned if an attach request was succesfully sent to the move_group node. This does not verify that the attach request also was successfuly applied by move_group.

| arg1, | |||
arg2 = None, |
|||
arg3 = None |
|||
| ) |
Specify a target joint configuration for the group. - if the type of arg1 is one of the following: dict, list, JointState message, then no other arguments should be provided. The dict should specify pairs of joint variable names and their target values, the list should specify all the variable values for the group. The JointState message specifies the positions of some single-dof joints. - if the type of arg1 is string, then arg2 is expected to be defined and be either a real value or a list of real values. This is interpreted as setting a particular joint to a particular value. - if the type of arg1 is Pose or PoseStamped, both arg2 and arg3 could be defined. If arg2 or arg3 are defined, their types must be either string or bool. The string type argument is interpreted as the end-effector the pose is specified for (default is to use the default end-effector), and the bool is used to decide whether the pose specified is approximate (default is false). This situation allows setting the joint target of the group by calling IK. This does not send a pose to the planner and the planner will do no IK. Instead, one IK solution will be computed first, and that will be sent to the planner.
