the same structure created in section 7.5 with the same parenting

relations.

For the animation, we will use the structure, a sphere, and three empties

to mark key locations for animation (Figure 7.26).

Figure 7.26 - Scene for animation

The objective is to make our structure grab the sphere and release it on

the opposite side. It is a simple animation, which would require a lot of

work to create without constraints.

Before we start, set all objects relations using the parenting tool. The

empty close to our arm's tip must be a child of the object at the top,

named "hand." Select the empty first and then the "hand." Press

CTRL+P to create a parenting relation.

Info: You will see a dashed line connecting the Empty and "hand" once

they have a parenting relation.
