Where's my robot lawn mower? Roomba-maker now has an answer: Terra

BEDFORD, MASSACHUSETTS - Robot vacuums have now been around long enough that you might watch one bump around a living room and think, why isn't there a robot that could mow my lawn? Turns out, it's not for lack of trying. For more than a decade, iRobot, the company behind the Roomba vacuumbot, has been working -- and working -- on robotic lawn mowers. Now it finally has something to show for the effort, though it's come at a cost. "Honestly, this robot drove me insane," said iRobot CEO Colin Angle after showing off Terra, the company's long-awaited first lawn mower.
