Minecraft Robot Rig 2.0
Blend file containing rig.
The complete Minecraft Robot character rig for Blender 2.9+.
You can view a video explaining how to use the rig below. The video is a bit older and features the 1.0 version rig but everything still works the same. Version 2.0 is just cleaner and works a little better. Plus it has bevels and some new face options.
See an example of the rig below.
