Armature Issue

I have two issues with my armature:

  1. I parented an eye to a bone but it does not follow the armature properly
  2. None of the body parts of my robot follow the armature properly.

Could someone please help me?

Only have one object with collision (Dynamic, Rigid Body, etc.). Set the others to no-collision. Make sure the parent has a scaling of 1 (ALT+S).
