Ordering the control objects in the correct hierarchy and linking them to joints
In this section, we need to organize our rig controllers in the correct hierarchy. Just like with all our parent/child hierarchies in our Animation Rigs, the hierarchy needs to be parented in the right order, so our rig works correctly.
Controller hierarchy
Like with our Alien Plant Control Rig, we need to figure out how we want our hierarchy to work.
Firstly, we want an overall root controller (RobotRoot) that can move our entire Animation Rig if we need to. That needs to be at the top of the hierarchy and the parent of everything in the Animation Rig.
Secondly, we want the body controller (RobotBody) as the child of the root controller. We just need to left-click to select and hold the mouse button to drag the RobotBody controller on top of the RobotRoot controller, as shown in Figure 15.19:
