If you decide you want root objects to always use their joint parameters, you
can turn off the Always Transform Children Of The World option.
Single, unlinked objects are hierarchies of one. An unlinked object is its own
root and is also a child of the World. Turning Always Transform Children of
the World will prevent you from transforming single objects in IK mode.
Animating with Applied IK
Select the end of a hierarchy > Hierarchy panel > IK > Set object parameters
such as Bind to Follow Object > Apply IK.
Applied IK requires you bind one or more parts of your IK structure to animated
follow objects. Once bound, you can select any object in your kinematic chain
and click Apply IK. This calculates the IK solution for each frame of the
animation and places transform keys for every object in the IK chain.
The Apply IK method of animation works best when you want objects in the
kinematic chain to match the motions of other objects exactly.
TIP Applied IK is a feature carried over from the earliest version of the software.
It is recommended that you explore the IK Solver methods first, and only use
Applied IK if you find the IK Solvers won't satisfy your needs.
