Developing robots with flea-like attributes seems to be quite popular these days, as researchers at the University of Lucca have apparently created a diminutive bot that was "developed to detect mercury poisoning in the ground and leap from place to place the way fleas or frogs jump." The creature measures in at ten-centimeters long and weighs just 80-grams, and can supposedly cover "vast amounts of land in shorter amounts of time" compared to less efficient pollution-seeking alternatives. Currently, the critters are purportedly being loosed in the wild with "special mercury-deteting sensors," so be sure not to squash any hard workin' mechanical pests if one accidentally hops in your tent.[Via The Raw Feed]
