Rigging with constraints
In this section, we will use empty objects and constraints to rig the tracks and wheels. In the following steps, we will bind the movement of the tracks to the rotation of an empty sphere using constraints:
- Create an empty sphere. To do so, press Shift + A, and find Sphere in the Empty menu.
An empty object is an object that exists but is not visible in renders. It is commonly used as a placeholder, reference, or rigging object.

- Select the tracks and find the Object Constraint Properties tab. Then, open the Add Object Constraint menu:

- Add a Transformation constraint:

This will create a menu in the Object Constraints tab, much like...
