A video tutorial on how to rig an assembly line robot with an armature for animation.
This video covers all the information in an article I wrote for BlenderArt Magazine.
Additionally, I went ahead and refined the rig presented in the first video with constraints and controller bones to simplify the task of animating.
Then I continued on to tidy up the rig a little and create custom bone shapes for the controller bones.
The completed .blend files are attached.
Feel free to ask questions,
