Snails with benefits? Our salt shaker might disagree. But some enterprising engineers over at Japan's Chuo University managed to turn this garden-variety pest into fodder for mechatronic inspiration. Based on the gastropod's preferred method of 'galloping' -- wherein waves of foot-to-head muscle contractions propel it forward -- researchers at the Mechatronics Lab created TORo II, an omnidirectional robot that could make its way to a hospital near you. Why's that? Well, the bot's large gripped surface area makes it ideal for narrow, slippery environments -- so it won't budge if knocked into (though you might wind up on the emergenc
