Category talk:DriveTrains
This Category:DriveTrain should focus on the way electrical (or other) energy is converted to motion.
The Category:Mechanical arrangement lists the various ways that the head and platform is moved around using these DriveTrain components.
It could do with a main page at some point.
If it is required the appropriate sections from these categories and the sections in the General_FAQ#Mechanical_3D_robot could be folded in and just a summary and link to main page left in their place. The category pages could be more light weight and the DriveTrain and Mechanical Arrangement topics could be better separated.
