Amidst all the whiz-bang technology that goes into motion-control and robotic systems --- motors, controllers, drives, and feedback devices --- one very important piece of the puzzle is often overlooked; the lowly cable hardware, and its support structure.

To avoid costly mistakes, take some time and learn about the design and selection of cable and track.
