Hexbug Robot Ants Can Outrace Real Cockroaches

Hexbug's touch-and-sound-sensitive mini-robots have always moseyed, not scurried. But their latest, the Ant, locomotes with wheel legs—not quite a wheel, not quite a leg—zippily enough to give real bugs a run for their money.

It's got a new butt sensor, in addition to the usual antennae. It's cheap too, only $10.
