Jul. 3--CAMBRIDGE, Mass.--Scientists at MIT have created what they believe is the world's first robotic snail, a humble collection of gears, wiring, and a rubbery membrane that creeps forward on a thin layer of gooey slime.

The robot was built to help scientists learn how snails and slugs manage to push themselves along on their slime trails, a method that puzzles biologists despite years of scrutiny. On a larger front, however, the snail is the latest -- and perhaps strangest -- development in the booming field of "microfluidics," which is the science of understanding how li...uids behave on a very small scale.

Just as engineers revolutionized electronics by...
