A few weeks ago we showed you how to build a BristleBot, a tiny vibrating robot (vibrobot) that is formed from the unlikely union of a toothbrush (with directional bristles) and a vibrating pager motor. Despite its simplicity, it drives like a drunken bat out of hell– propelled by the ratcheting action of the vibrated bristles. Of course, toothbrushes aren’t the only system where you can find find oriented bristles. Approaching this process from an entirely different perspective, it turns out that certain types of velvet can also form a directional bristle system that can be driven with vibrations. Here we build a plush racing snail– a velvet vibrobot that crawls forward… at a snails pace.

Wow, I had no idea some velvet had this property! Lenore, you’ve got yourself a race. – Link.
