Now as we rotate the Box01 object (which is not the bottom support, but the bottom piece of the robotic arm) you can see the whole arm rotates with it. That means everything is linked as it should be.
Let's animate the thing. Go into Auto Key animation mode. Select Box02.
Follow these steps in order: press Set Key (1); move the current frame slider to frame 15 (2); rotate the object 45 degrees towards you (3). For added precision use angle snap (a) (shortcut: A) and set the axis to Local (b). A key will be created automatically (4).
