The snail is probably one of the most picked-on creatures in the
world. How could this small, slow animal possibly benefit anyone, other than on the French menu as escargot? Even gardeners
dislike snails! However, researchers are now copying the design of the snail when making small robots. The advantage is that
snails are very small and have only one foot, making them mobile and potentially simple to copy. Snails are able to travel
straight up walls and even across ceilings, a sought-after goal for small robots.
The RoboSnail was designed as a rubber "foot" that
slides on a thin layer of silicon oil. Real snails actually travel by three different modes of movement, and researchers have
copied two of them. Both involve using pressure produced by a layer of mucus (or oil) beneath a flexible boundary. A special
version of the RoboSnail has been designed to clean aquariums, crawling along the sides of a glass or acrylic aquarium just
like a snail.
part of God's creation has a purpose and function given by the Creator. One of those purposes for the natural world is to
provide human beings with engineering models that we can study and learn from in order to improve our own designs. Even the
lowly snail fulfills this purpose of the Creator.
