/diy/ - Do It Yourself

I have a small flexible tube, and I need to be able to move it. My idea is a number of wires (2-4) controlled by a motor (or whatever is best) that pull whatever wires necessary to lift in the direction required. So the picture is the tube (Black) surrounded by 4 red wires that the motor (or whatever is best) will pull to lift the tube.

My question is, a motor has 2 directions, forward and back, if I go with 3 or 4 cables, how do I get it to control different wires?

I feel like I have asked this terribly.
