Directional Friction

It doesn't look like there's any way to implement this, is there?
To be more specific, if I have a (small) worm, and I want it to crawl, if it's on agar, it creates a small channel due to water pressing down on it. This channel prevents the worm from moving sideways when it wriggles, and thus, it moves forward.
Another example, would be a snake -- snake skin exhibits reduced friction in one direction, (presumably) facilitating forward motion.
If directional friction isn't possible, are there any suggestions? One possibility is to affix wheels to the bottom, much like a train, so that movement would be restricted more laterally (due to friction of the wheel against the ground) than it would be forward/backward.
