Allows to make every parameter's and computation wrt. a new robot base. This is handy if one wants to have everything computed wrt. a fixed hand frame. I needed a way to be in the hand frame, but also have the PD cartesian gains to also be in the hand frame.
Allows to set an optionnal offset to the end effector. E.g. Be able to reason about a screwdriver (no URDF link) grasped from a gripper.
Uses a ROS Service to update the pre/post segments as a geometry_msgs/PoseStamped. Just set the frame_id to apply the desired pre/post segments. An empty frame_id will remove the corresponding segment.
# Ability to add a chain before or after the robot chain (parsed by the URDF)
# Removes the chain if the frame_id is empty. Otherwise, overwrites the previous chain.
geometry_msgs/PoseStamped pre_robot_chain_offset # Attached before the robot base link
geometry_msgs/PoseStamped post_robot_chain_offset # Attached after end effector link

This should only bet set when the controller is stopped.

Update the feedback states with the correct frame_id.
