Since you are worrying about the visual appearance of the robot, I would not recommend spinning the wires. Instead, go to your local electronics store and buy wire with an outer casing. It makes everything look nice and neat, and in some stores, you have a choice of colors, so you can chose the wire to match the color of your robot. You will also have a choice of how many wires you want in the bundle, so that will eliminating having to run several strands side by side. We use these wires on our robot and they make it look great, and neat.
